Abstract
The study examined the relationship between teacher support and reading performance via the multiple mediation effects of reading engagement (emotional engagement and cognitive engagement). Data were extracted from Programme for International Students Assessment (PISA) 2018, with a sample of 171,429 adolescents from 5,692 schools across 22 countries/regions. Using multilevel serial mediation analysis, the results confirmed that teacher support enhanced adolescents’ reading performance by fostering reading engagement. Emotional engagement and cognitive engagement worked in tandem and sequentially as serial mediators. Explicitly, the positive impact of teacher support on reading performance was positively mediated through emotional engagement solely, and serially mediated through emotional engagement and then cognitive engagement. Cognitive engagement also exerted significant mediating effects in most territories. The current study provides new findings in depicting the sole and simultaneous functions of emotional and cognitive engagement in relations with teacher support and reading performance with cross-national evidence. It also suggests the practical implications for instructors to apply various pedagogical interventions to support adolescents’ reading performance growth.
Introduction
Skilled reading performance is key to adolescents’ lifelong learning and full participation in modern societies. Among the various determinants, teacher support has proved to be significantly influential on reading achievement (Wang & Hu, 2022; Guay et al., 2019; Khine et al., 2023; Ma et al., 2021). If student perceived teacher support for them, they exhibited higher level of engagement and would be more likely to show positive emotions (e.g., enjoyment) and use metacognitive strategies in learning process, thus gain better academic achievement (Förtsch et al., 2016; Tao et al., 2022). According to the model of reading engagement (Guthrie & Wigfield, 2000), reading engagement is also pivotal in developing reading performance, and has been acknowledged to mediates the instructional effects on reading outcome (Wigfield et al., 2008). Nevertheless, few studies shed lights on how individual engagements would separately or jointly predict reading development and the factors that promote them (Jang et al., 2022). Especially, we have far less knowledge about the influences from the teacher-related factors (Gu & Lau, 2023).
Therefore, this study aims to reveal the synergistic effects on reading growth from two contributing dimensions: teachers who are important others for students in the school setting, and individual factors which are determining for student development. It also provides valuable insights to address the discrepancy by examining the impact of teacher support on reading performance through the multiple mediation effects of reading engagement (emotional and cognitive aspects). Specifically, this study investigates the serial mediating effect of emotional engagement and cognitive engagement, and how it relates to teacher support and reading performance. This study offers empirical evidence to the reading engagement theory by exploring the mediating role of reading engagement between teacher support and reading achievement from diverse cultural contexts. Meanwhile, it also provides pedagogical implications on reading in provoking students’ positive emotions and activating their cognitions, which contribute much to the educational psychology research. Based on above, the multilevel serial mediation is adopted in the sample of 15-year-old students to gain international evidence on the interrelationships among studied variables.
Literature Review
Teacher Support, Reading Engagement and Reading Performance
Teacher support refers to the extent to which students perceive the teachers’ help on their study (Organisation for Economic Cooperation and Development [OECD], 2019; Wentzel, 2016). An autonomy supportive teacher acknowledges students’ perspectives (Bureau et al., 2021), provides opportunities for choice (Reeve & Cheon, 2021), or motivates them to participate in the interesting learning activities (Wentzel, 2016). These instructional behaviors that promote student intrinsic motivation are termed as autonomy support (Jiang & Zhang, 2021; Tao et al., 2022). Extends beyond creating an emotionally supportive climate, teacher support also involves direct strategy instruction, which activates students’ cognition by relating to their own experience (Wentzel, 2016), building prior knowledge into new concepts (Kitsantas et al., 2021), relating facts and ideas (Förtsch et al., 2016) or using questioning techniques (Law, 2011). These instructional behaviors that support students in academics are termed as academic support (Patrick et al., 2007; Tao et al., 2022). In the reading context, the PISA-related study conceptualizes teacher supportive behaviors in encouraging students’ independent thinking and free expressions of their own opinions about a text (Yu et al., 2022), and explicit explanations on reading text, such as to relate the reading materials to real life or build the text information on previous knowledge (F. Zhang et al., 2024).
Grounded in the model of reading engagement, individual factors hold distinctive importance on reading development. It also assumed that this decisive impact could be influenced by classroom instruction, combining motivational enhancing practices, and reading strategy instruction (Guthrie & Wigfield, 2000). A supportive teacher plays a vital role in providing such classroom-based instructional practices. Therefore, the model underpins the theoretical foundation of our conceptual framework in which we aimed to explore the relationship among support from teacher (who provides classroom instruction), reading engagement and reading performance. As the model posited, reading engagement incorporated various aspects (Guthrie & Wigfield, 2000). According to the Programme for International Assessment (PISA) 2018, reader’s emotional and cognitive aspects of engagement are the consistently robust predictors of reading performance (OECD, 2019). Substantial PISA-related studies have conceived of reading engagement a joint functioning of motivation and metacognitive strategies (Gu & Lau, 2023; Jang et al., 2022). Followed the PISA 2018 framework and previous studies, we explore reading engagement as a two-dimensional construct, namely, emotional engagement, and cognitive engagement and will further clarify these conceptual terms in the following sections.
The effect of teacher support on reading achievement has been extensively identified but yielded inconsistent results (Guthrie & Klauda, 2014; Kikas et al., 2015; Wang & Hu, 2022). When teachers utilized motivational strategies and provided cognitive support, students exhibited higher reading proficiency in Hong Kong (Law, 2011). However, in a longitudinal study (Silinskas et al., 2016), 13% of Finnish-speaking children’s reading skills showed no associations with teacher support, while 49% of children acquired reading skills slowly, irrespective of teachers’ support in reading. Kikas et al. (2015) discovered a negative correlation between teacher individualized support and reading proficiency of Estonian children. The reasons behind the inconsistency might be attributed to the multifaceted nature of teacher support and the differentiation of research types. In the previous studies, teacher support was evaluated either on classroom level (e.g., Law, 2011) or individual level (e.g., Kikas et al., 2015). Some longitudinal studies are restricted to the sample size, thus cannot involves an extensive sampled population. Therefore, this study adopted a secondary analysis extracting massive quantitative data from a large-scale assessment PISA that involves different countries/regions, to gain more empirical evidence on the inconsistent results. In this study, we examined the teacher support for the entire class and hypothesized it can facilitate successful reading performance by fostering student engagement across countries/regions.
Teacher Support, Emotional Engagement, and Reading Performance
Emotional engagement refers to the emotional responses and motivational commitment to reading (Gu & Lau, 2023; Ho & Lau, 2018). Reading enjoyment is a vital form of intrinsic reading motivation pertaining to the emotional aspect of reading engagement (Mak et al., 2016), which is one of the most frequently investigated variable that measures positive and enjoyable feelings about reading. Considerable studies have verified that emotional engagement can be affected by teacher support (Guay et al., 2019; Khine et al., 2023). Teacher autonomy support contributed to student intrinsic motivation and reading achievement in a large longitudinal study from Canada (Guay et al., 2019). Additionally, reading enjoyment is better predictive of reading performance than other moderators, such as extrinsic motivation or amount of reading (Taboada et al., 2008; Wang & Guthrie, 2004), with significant cross-country difference (Cheema, 2018; Ho & Lau, 2018). Students who read for enjoyment or are intrinsically motivated to read appear to be more skilled in reading (Mullis et al., 2007). Some researchers have further confirmed that teacher support can also boost reading improvement by fostering academic enjoyment in the mainland China (Hu & Wang, 2022a; Ma et al., 2021). The above cited studies provide the impetus for the present study, unfortunately, only the Chinese sample were examined. The present study aimed to make an extension of their studies with a larger size and more various sample to get a broader view of this issue. Therefore, it is hypothesized that emotional engagement could mediate the relationship between teacher support and reading performance across countries/regions.
Teacher Support, Cognitive Engagement, and Reading Performance
Cognitive engagement is learners’ self-regulated psychological efforts in learning process. Readers are cognitively engaged when they exhibit deliberate, selective, and sustained attention to comprehend reading tasks (Guthrie et al., 2012). While reading printed or digital information, readers are required to retrieve the target information, make inferences, or stay selective and assess the sources of information to minimize their visits to irrelevant pages (OECD, 2011). These abilities draw on the readers’ involvement of metacognitive strategies, that is, understanding of literal meaning, summary of main idea as well as the assessment of text quality and credibility (OECD, 2011). The cognitive engagement is widely operationalized as learning strategies (Appleton et al., 2006; Tao et al., 2022; Walker et al., 2005), correspondingly metacognitive reading strategies in PISA studies (Jang et al., 2022; Mak et al., 2016). Therefore, the three facets of PISA metacognitive reading strategies lie in well with the manifestation of reading engagement, which are integral for reading growth, and underlie the construct of cognitive engagement in this study.
The perceived teacher support is identified to have beneficial influence on cognitive engagement (Lau & Chen, 2013). Young (2005) also demonstrated that US students employ learning strategies more extensively when taught by caring teachers who give supportive feedback. Numerous studies have also discovered a positive correlation between metacognitive knowledge and reading performance (Gu & Lau, 2023; Jang et al., 2022; Trigueros et al., 2020). Prominent and self-regulated readers can effectively interact with a text by using more appropriate reading strategies, thus are more high-achieving in the reading test (L. Zhang et al., 2014).
To conclude, previous studies have supported that cognitive engagement is significantly associated with both teacher support and reading proficiency. However, little is known about whether teacher support can enhance students reading performance by promoting their cognitive engagement. The similar interrelations were merely investigated in chemistry or mathematics (González & Paoloni, 2015; Yıldırım, 2012). The scarcity of studies has probed into the multilevel mediation hypothesis of these variables in terms of adolescents’ reading. To fill this gap, this study hypothesized that cognitive engagement could mediate the relationship between teacher support and reading performance.
The Associations Between Emotional and Cognitive Engagement
Motivation researchers have delved into how motivation affect metacognition. Pekrun (2006) highlighted that those academic emotions (e.g., enjoyment) influence various cognitive processes and metacognitive knowledge. Intrinsic motivation is viewed as an energizer that helps students cognitively engaged during reading. For instance, emotionally engaged readers, who have stronger desire to read, will get deeper impression of what they have read and are better at connecting text will prior knowledge in future reading (Taboada et al., 2008). Empirical evidence also indicated that that some motivational attributes affect how readers approach (by use of strategy and metacognition) reading text (Wigfield & Tonks, 2004) or influence depth of cognitive processing (Schiefele, 1999) to promote text comprehension.
Recent researchers explored whether the impact of emotional engagement on cognitive engagement will subsequently be passed on the reading performance (Miyamoto et al., 2019). In German, sufficient empirical evidence confirmed the mediating role of metacognitive strategies in the relationship between intrinsic motivation and reading comprehension (Schiefele et al., 2012; van Kraayenoord & Schneider, 1999). Based on the above literature, emotional engagement can exert either direct effect on reading performance, or indirect effect through cognitive engagement. Given the solid bond of emotional engagement with teacher support, it is assumed that teacher support could enhance emotional engagement and this enhancement would have a chain effect on reading performance through cognitive engagement. As a result, we conjectured that the effect of teacher support on reading performance was serially mediated by emotional engagement and then cognitive engagement.
The Present Study
In light of previous literature review, perceived support from teacher holds distinctive importance on student emotional engagement (Guay et al., 2019; Hu & Wang, 2022b; Ma et al., 2021) and cognitive engagement (Lau & Chen, 2013), and the two aspects of reading engagement also significantly related to reading performance (Cheema, 2018; Gu & Lau, 2023; Ho & Lau, 2018; Jang et al., 2022; Trigueros et al., 2020; L. Zhang et al., 2014). Despite these direct effects, the indirect effects of teacher support on reading performance have not yet been fully explored. Although the model of reading engagement has highlighted the mediating role of reading engagement, the existing studies mainly focused on emotional aspect of reading engagement as a mediator (Ma et al., 2021). The cognitive factors are primarily explored in the science-related subjects (González & Paoloni, 2015; Yıldırım, 2012). Recent evidence has suggested the mediating role of cognitive factors (such as cognitive flexibility) that could benefit reading performance (Hu & Hu, 2024) and captured the interplay between emotional and cognitive processes (Miyamoto et al., 2019; Schiefele et al., 2012). Therefore, it is assumed that the subtypes of reading engagement function simultaneously to impact the relationship between teacher support and reading performance. To my knowledge, the internal mechanism behind teacher support, emotional engagement, cognitive engagement and reading performance remains an open question, which constitute the major motivation of our inquiry. To address these gaps, we proposed the conceptual framework, to reveal the under-explored relationships to enrich the existing model of reading engagement, which also offers compelling empirical evidence by delineating the constructs in the context of PISA data. Thus, we developed our hypothesized serial mediation model (see Figure 1) to depict the mechanism of how teacher support predicts reading performance. As perceived teacher support is measured at the student level, while it may vary across classes or schools. This study attempts to reduce common method variance by employing a multilevel mediation analysis. To summarize, our research will address three hypotheses as follows:
H1: The effect of teacher support on reading performance is solely mediated by emotional engagement across countries/regions.
H2: The effect of teacher support on reading performance is mediated by cognitive engagement across countries/regions.
H3: The effect of teacher support on reading performance is serially mediated by emotional engagement and then cognitive engagement across countries/regions

The serial mediation model of how perceived teacher support predicts reading performance through emotional engagement and cognitive engagement.
Method
Data Source
The data were obtained from PISA 2018 database, which is the latest survey with reading as the major domain. PISA is the most influential large-scale survey administered every 3 years to assess the performance of 15-year-old students. The massive PISA data provides the most comprehensive and rigorous cross-national evidence for educational research and policymaking, thus often serves as an authoritative benchmark for evaluating the quality of educational systems worldwide. After eliminating the countries whose studied variables are not significantly correlated in the data preprocessing, we selected all the other 22 countries/regions (See details in Table 1) that performed above OECD average in PISA 2018, including a whole population of 171,429 (female = 84,905) participants from 5,692 schools, to draw on the experiences of their successful educational systems.

Variables
As an independent variable, four items were used to assess teacher support (TS) from students’ perception. The adolescents were asked to rate how frequently their teacher exhibited a particular behavior, for example, “encourages students to express their opinion about a text (ST152Q05IA)” represented autonomy support, “helps students relate the stories they read to their lives (ST152Q06IA)” represented academic support (The Cronbach’s α values ≥ .807 in all territories).
As a dependent variable, the students’ reading performance (RP) was measured by scores of the computer-based reading assessment. During the assessment, students were required to click on links, browse the website, evaluate documents and retrieve relevant information. The assessment adjusts its difficulty by dynamically extracting portions of the item pool based on how the students performed in the previous stage.
Two mediating variables were selected to capture the two subcomponents of reading engagement. Five items were used to measure emotional engagement (coded as “JOY”), for example, “Reading is one of my favourite hobbies (ST160Q02IA)” (The Cronbach’s α values ≥ .812 in all territories); Cognitive engagement was a latent variable measured by three variables of metacognitive strategies, understanding and remembering (META1), summarizing (META2) and assessing credibility (META3). META3 was newly assessed to access information credibility and quality, concerning the emerging genres of digital-based reading, such as e-mail. For each scale, students are asked to evaluate a set of strategies regarding their usefulness for solving a given reading task. Six items were used to assess META1, five items each for META2 and META3, for example, “I underline important parts of the text (ST164Q04IA)” (The Cronbach’s α values ≥ .804 in all territories).
Gender and ESCS were selected as control variables to account for individual variations. As a dichotomous variable, gender was dummy recoded as female = 1, male = 2 (Hardy, 1993).
Data Preprocessing
The data preprocessing consists of imputation, dummy coding, normalization, and correlation analysis. First, missing values were imputed by K-nearest neighbor (KNN). KNN imputation uses values of the neighbors and the weighted average of their values to fill in the unknown value, which has been widely used in to predict the missing data of large-scale assessment datasets (Hu & Yu, 2022). This was performed in R (R Core Team, 2019) using the KnnImputation function in the DMwR2 package (Torgo, 2020). Next, dummy coding was used to convert the gender variable into a dummy variable, as noted above. Data normalization was in accordance with centering and variance scaling principles. Correlation analysis was conducted to capture significant relationships among the variables. The correlations between variables for all 22 territories are calculated (see Supplemental Materials). As suggested, all the variables are significantly correlated with each other. The PISA data are highly clustered in nature, with students nested in schools and schools nested in countries. To account for the hierarchical structure of the data, intraclass correlation coefficients (ICCs) were calculated to assess the need for multilevel analysis.
Data Analysis
The present study adopted a multilevel serial multiple mediator mediation model, as there are two mediators and it assumes potential chain effects among mediators, as well as accounting for the inherent feature of hierarchical data. The statistical model can be classified as a 1-1-1 multilevel mediation model (Krull & MacKinnon, 2001), as all variables were measured at level-1 (student level). The hypothesized model was based on the multilevel structural equation model (MSEM) approach, with a measurement model, a structural model and model fit as necessary components.
The statistical model was performed with the cfa and sem functions in the lavaan package (Rosseel, 2012) using R. Initially, confirmatory factor analysis (CFA) was conducted to confirm the validity of the latent construct, that is, cognitive engagement based on three indicators. CFA was also accommodated within the multilevel framework, which permits elements of some coefficient matrices to vary at the cluster level. As for structural model, the total, indirect and direct effects were calculated to display the paths and quantify the mediation effects. To take higher-level effects into account, the scores of variables at the student level were clustered at the school level, the of which was to be analyzed at the school level. The multilevel mediation model was run at the within-and between-level spontaneously to quantify the variance of different levels. Regarding the effect size of the total indirect effects, the proportion mediated (PM) was computed as the effect size measure.
The model fits of the CFA model and mediation model were both calculated. The assessed fit indices include the comparative fit index (CFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). As a rule of thumb, CFI greater than 0.90, RMSEA lower than 0.08 and SRMR lower than 0.1 indicate an acceptable model fit (Hu & Bentler, 1999).
Results
Preliminary Analysis
The ICC above 0.059 (see Table 2 in bold) suggests that a multilevel model should be preferred (Cohen, 1988) and the students’ reading proficiency presents discrepancies across schools for all datasets. Table 2 also presents the standardized factor loadings for the latent variable. All the indicators significantly loaded on their latent variable (95% CI excluding zero) and above the cutoff value (above 0.40) of accepted standardized factor loadings.

Total Effects and Direct Effects of Teacher Support on Reading Performance
In Table 4, the total effects are significantly positive for all datasets. Regarding the direct effect, it appeared to be nonsignificant (c′ in bold) in most territories. The direct effect is often used as statistical evidence to measure the strength of mediation (Zhao et al., 2010), which will be discussed later.
Indirect Effects of Reading Engagement
The total indirect effect (ab) examines the mediating role of reading engagement. As Table 4 suggests, the unstandardized regression coefficients range from 0.031 to 0.115, and the effect size is reported to measure the total mediated effects of teacher support on reading performance through reading engagement. Since a suppression effect, when the direct effects c’ and mediated effects ab have opposite signs (MacKinnon et al., 2000), were detected in this study, there are some territories whose effect sizes are above 1 (see Belgium, Canada, France, Macao, Germany, Sweden). The effect sizes of the other datasets range from 58.7% to 95.9%. All indicators of effect size suggest that a large proportion of effect from teacher support on reading performance is mediated through two intermediary variables, indicating that reading engagement is a significant mediator in all territories.
The specific indirect effect represents the ability of the intermediary variable to mediate the effect controlling for all other mediators (Preacher & Hayes, 2008). Table 5 reports three mediating effects (a1b1, a2b2, a3b3) of two meditators, that is, JOY and META. According to Table 5, JOY is a significant and positive mediator for all datasets. The unstandardized regression coefficients range from 0.0062 to 0.0297, among which China (B-S-J-Z) exhibited the largest impact. With respect to META, 18 out of 22 territories reported significantly positive mediating effect of META between teacher support and reading performance (a2b2), while only a few territories, that is, China (B-S-J-Z), Chinese Taipei, Singapore, and Sweden, reported no significant mediating effect. Additionally, the relationship between teacher support and reading performance are serially mediated from JOY to META (a3b3 significant) in all territories. By comparing three mediating effects, META is the upmost mediator in the largest number of territories (16 out of 22), eliminating China (B-S-J-Z), Chinese Taipei, Singapore with JOY as their predominant mediator, and Australia, Estonia, Sweden reporting the most significant mediation effect through JOY and then META.
Discussion
Teacher Support, Reading Engagement, Reading Performance
Our results indicate consistency on the total effects of teacher support on reading performance across different territories. According to Cohen (1988), the effect size over 0.50 is considered large. In our study, the effect sizes of total indirect effects strongly indicates that mediation of reading engagement did exist and provide compelling evidence, from a total sample of 171,429 participants, that reading engagement mediates the relation between teachers support and reading outcomes.
Notably, the strengths of mediation differ across our sampled territories. Methodologists have proposed interpretations of the implications of various medication types. Zhao et al. (2010) asserted that full mediation indicates the validity of the hypothesized meditation framework, while partial mediation points to the likelihood of an omitted mediator. It is claimed that a significant direct effect usually results from the omission of a mediator from the model (Shrout & Bolger, 2002). Correspondingly, more than half of the territories (c′ in bold, see Table 4) exhibited a full mediation pattern, which extensively validates our mediation hypotheses as consistent with the hypothesized model. The remaining territories should be considered by future studies to explore additional mediators for a comprehensive model.
Emotional Engagement as a Mediator
The present study identifies that emotional engagement is a persistent predictor in relation to teachers’ facilitation of reading outcomes. Moreover, our study provides new findings by extending the current Chinese context in literature with the cross-national generalizability of 22 countries/regions. Teacher support can help students exert control over their study, maintain affective relationship with teachers and achieve desired competence. Thus, students who perceive teacher support for their basic needs of autonomy, relatedness and competence become intrinsic motivated to improve their academic performance (Deci & Ryan, 2000). In terms of reading, supported students are easier to gain positive reading experiences or enjoyment, consequently, improve the reading amount and breadth, strategy use and achieve higher reading achievement (Cheema, 2018; Guthrie & Wigfield, 2000).
Intriguingly, the model coefficient for China (B-S-J-Z) was largest among all contexts, and significantly larger than the other path coefficients (a2b2, a3b3). There are two possible explanations for this exception. First, recent studies have rejected the stereotypy of Chinese students as passive learners. Instead, they exhibited high level of reading enjoyment than OECD average (Gu & Lau, 2023; Ma et al., 2021; Wang & Hu, 2022). As the Confucian heritage culture place high value on education, Chinese learners maintain positive attitude toward learning, hence are more devoted and dedicated in academics (Watkins & Biggs, 2001). Second, the new reforms in the curriculum, pedagogical methods have collectively shaped the Chinese educational system with “the Chinese characteristics for a new era.” The current curriculum in mainland China attempts to abandon rote learning and shift to a humanistic and competence-based approach (Ministry of Education of the People’s Republic of China, 2022). The educational objective is underpinned by equipping the students with core competences, rather than merely knowledge, that prepare them to fulfill their potential in personal and occupational life. The primary goal for teachers is to engage students in an active, cooperative, and reflective learning environment (Tam, 2015). Therefore, Chinese teachers are guided to use innovative teaching methods to motivate and engage adolescents, which dispelled the traditional impression of the Chinese classroom as authoritarian and mechanical skill-training (Guo et al., 2018; Ma et al., 2021; Qian & Lau, 2022). The comprehensive influences from the learners, cultural backgrounds and educational systems contribute to this “Chinese exception.” Additionally, the study results also reveal that the new reform works efficiently in encouraging Chinese teachers to use diverse pedagogies to engage adolescents in light of their outperformance in the PISA 2018 reading test.
Cognitive Engagement as a Mediator
The findings confirm the mediation effect of cognitive engagement among most of the territories, supporting hypothesis 2. This is congruent with the studies that verified the parallel correlations in science literacy (Yıldırım, 2012), and one of the first study to examine these correlations in the reading domain. Among all intermediary variables, cognitive engagement proved to be the most influential in promoting reading performance in the majority of territories. It is plausible that when teachers provide explicit strategy instruction, students have a better grasp of reading strategies, and those cognitively engaged readers are more proficient in decoding a text, understanding words and constructing the meaning of a text (Miyamoto et al., 2019). Hence, teacher support can precisely predict reading comprehension by facilitating the cognitive engagement.
However, META did not serve as a sole mediator in some territories. Further examination of their path coefficients showed that TS is nonsignificantly correlated with META (a2). According to the 2018 PISA framework, readers become independent of the teacher after these strategies have been acquired (OECD, 2019). Some European researchers also found that teacher autonomy support failed to predict students’ metacognitive strategy use in a longitudinal study by arguing that metacognition was a more stable personality trait than intrinsic motivation, thus was harder to be influenced by teacher support (Schuitema et al., 2016). In the Swedish context, the deterioration of reading literacy and its negative correlation with ICT accessibility according to the PISA results initiated the government’s concern about the excessive digitalization in education and a call to revert to traditional pedagogical methods in reading instruction (Díaz et al., 2024). Research showed that Swedish teachers resist technology integration (Syahrial et al., 2022) and lack the preparation with technology (Schmitz et al., 2023), which might result in inadequate and inefficient teacher support for students’ cognitive engagement. The evidence above could possibly explain the result why there were nonsignificant associations between TS and META in these territories.
Serial Mediator of Emotional Engagement and Cognitive Engagement
Our results suggests that adolescents who perceive support from their teachers feel more emotionally engaged and thus spontaneously use more complex reading strategies to improve reading performance. More importantly, our study fills the gap by depicting the internal mechanism and the simultaneous function of subcomponents of reading engagement that relates to teacher support and reading performance. The mechanism behind can be explained by the following assumptions. The teacher-supported students are more emotionally engaged. Such readers might easily get involved in deep interactions with the text (e.g., immerse in the plot, empathize the characters, select the relevant information), and therefore adopt sophisticated and extensive reading strategies, such as underline the important sentences, relating personal experiences to the text or assess the information source, to help interpret the text. Additionally, reading enthusiasts read and use metacognitive strategies more frequently and become more competent in reading strategy use. Even though teacher support fails to impact reading performance through metacognition, teachers can facilitate students’ reading achievement by stimulating their interest in reading, whereas students driven by intrinsic motivation will activate their metacognition when processing reading texts. This hypothesis is supported with consistent evidence from all sampled countries/regions, which generalizes the research findings and provides global researchers with cross-national evidence. As Table 5 illustrates, the serial mediating effect maintains the most significant in Estonia, compared with the other mediators. From Estonian Lifelong Learning Strategy 2020 to its follow-up of the Education Strategy 2021–2035, the key educational goals were set out to achieve the personalization and diversification of learning (Ministry of Education and Research of Estonia, 2021). Our results corroborated the implementation of educational policy decisions in cultivating Estonian population’s lifelong learning competences, such as learner autonomy, growth mindset etc.
Conclusion
This study contributes to the educational field by illustrating multiple mediation pathways among adolescents’ perceptions of teacher support, emotional engagement, cognitive engagement and reading performance, which exacts the sub-datasets of 22 countries/regions from a large-scale educational assessment. First, it reinforces the mediating role of emotional engagement in relations with teacher support and reading performance in all contexts. Second, teacher support exerts positive, significant indirect effect on reading performance through cognitive engagement in most places. The findings verify the theoretical assumptions of reading engagement theory that instructional practices can take effects through reading engagement to facilitate reading performance. Empirically, the findings provide solid and reliable evidence with a relatively wide range of sample, as few studies have extensively investigated this issue from as many datasets with diverse countries/regions at once. Thus, this study offers a comprehensive depiction by employing PISA data, which can trigger general interest and allow cross-national/regional comparisons for global educators, scholars, and policymakers. Furthermore, this study further clarifies the serial mediating effect of emotional engagement and then cognitive engagement, highlighting how two mediators work together to predict reading performance. Theoretically, it also adds new findings to the reading engagement model by revealing the internal mechanism of how teacher support predicts the reading performance via reading engagement, that is, the simultaneous function of emotional and cognitive engagement in relations with teacher support and reading performance should be taken into account. The research findings address the synergistic effects of situational factor (teacher support) and individual attribute (emotional and cognitive constructs), and suggest teachers to utilize motivational enhancing practices and cognitive activation strategies, which are of vital importance to promote reading growth. However, there might be equivalent mediators that remain to be further explored for contexts in which reading engagement serves as a partial mediator.
Implications
The mediation hypotheses of present study have great practical implications. On the national level, the government should devote to promoting the competence-oriented educational reforms and multi-dimensional evaluation. The policy initiatives should proactively support schools and teachers in establishing an inclusive environment that student’s perceptions of instruction quality and sense of fulfillment are highly valued. On the school level, teachers’ belief of multiple intelligences and sustainable development should be encouraged to allow teachers being more emotionally and cognitively supportive. As the findings indicated that students’ perception of teacher support is indirectly correlated with reading performance through emotional engagement and cognitive engagement. Therefore, it is essential that teachers attach great importance to improving reading enjoyment and metacognitive strategies. Moreover, the study showed that the effect of teacher support on emotional engagement will serially take effect on reading performance through cognitive engagement. Therefore, it is especially meaningful for adolescents to receive more joyful reading experience from teachers. For learners whose metacognition has weak or no associations with teacher support, continuous enhancement of reading enjoyment is still advisable, as it will rouse an intensive drive that promotes reading strategy use to achieve higher performance at length. To promote reading engagement, it is considered as a general rule for teachers to create an enjoyment-inducing classroom climate and provide academic scaffolding with sufficient reading strategy instructions. The process feedback from teachers can also help students realize their academic potential (Hu & Zhang, 2024).
Limitations
There are some limitations to be acknowledged. First, it is a cross-sectional study collecting data from self-report questionnaires, so causal relations could not be established. Future studies are advised to consider in-depth observations or longitudinal designs to validate the students’ perception of teacher behaviors and detect the dynamics of individual development, which may provide more conclusive evidence on the tested relations. Comparable studies can be conducted to reveal the potential reasons behind the differences across countries/regions from the perspectives of the instructional, individual and cross-cultural differences. Second, the studied variables are multiple-dimensional constructs that could be interpreted differently across studies, there might be equivalent mediators that remain to be further explored. It is beneficial to identify other individual factors such as control-value appraisals, to expand the current findings on reading instructions and learning in further studies.
