Abstract
BACKGROUND:
While studies have investigated relationships among learning motivation, social presence, and cognitive presence, there appear to be no studies on the inclusion of industry talks and the theory of inventive problem-solving (TRIZ) in strengthening engineering students’ learning motivation, social presence, and cognitive presence within a blended learning setting.
OBJECTIVE:
This study investigated the influence of industry talks and TRIZ on learning motivation, social presence, and cognitive presence in a blended learning environment.
METHODS:
Data samples were obtained from 98 engineering students in a blended learning course and analysed using Spearman’s correlation test, regression, ANOVA, and
RESULTS:
Findings suggested that TRIZ and industry talks strongly, positively, and significantly correlated with learning motivation, social presence, and cognitive presence. A well-rounded learning experience compounded of TRIZ and industry talks significantly affected learning motivation, social presence, and cognitive presence, thereby enhancing students’ programme outcome (PO) achievement.
CONCLUSIONS:
These findings can be attributed to the students’ independent learning capabilities with TRIZ and industry talks. Analogically, embracing TRIZ and industry talks helps turn blended learning into a “sweet instead of bitter pill to swallow” for engineering students in the face of the COVID-19 pandemic.

Introduction
The outbreak of the COVID-19 pandemic severely impacted the emotional functioning and motivational quality of many students [1]. This pandemic has somewhat forced a change in the landscape of conventional teaching and learning methods in higher education. Many higher learning institutions around the world were forced to either fully or partially migrate their physical classrooms to virtual learning environments. Consequently, the use of blended learning and digital education tools slowly became a staple in teaching and learning practice that many educators around the globe had to embrace [2–6].
Researchers have reported challenges in implementing blended learning from the perspectives of both students and educators. Some of these challenges include technical challenges, organisational challenges, instructional design challenges, self-regulation challenges, challenges in using technology for teaching and learning, training support challenges, increased class preparation time, and fairness in online grading [7–10]. If educators were compelled to use blended learning for emergency remote teaching whilst confronting its challenges in the face of the COVID-19 pandemic, then blended learning could turn out to be a “bitter pill to swallow” for both learners and educators.
Studies have dived into the constructs of learning motivation, social presence, and cognitive presence, and their impacts on students’ learning performance in a blended learning environment [11–13]. Researchers have also investigated the success of a unique problem-solving method known as the theory of inventive problem solving (TRIZ) in aspects of education such as entrepreneurship education, industrial training, and engineering design [14–17]. Studies found that the educational experience of students also improves with more frequent industry talks and engagement [18, 19].
However, there is still a need to study how the inclusion of industry talks and TRIZ correlates with engineering students’ learning motivation, cognitive presence, and social presence during the COVID-19 pandemic. To understand this relationship, the following research question is proposed:
How are TRIZ and industry talks related to the learning motivation, social presence, and cognitive presence of engineering students in a blended learning setting?
Therefore, it is of interest for this study to investigate the impacts of TRIZ and industry talks on learning motivation, social presence, and cognitive presence in the blended learning environment of engineering students. The study begins with a review of literature on the relevant variables and development of the hypotheses. The research and data collection methods are then described, followed by the data analyses, results, and discussion. Finally, the conclusions are drawn together with the directions for future research.
Literature and hypotheses development
Learning motivation
According to Lin et al. [20], learning motivation is a mediator between stimulus and response, where learners have different knowledge acquisition needs due to their distinct and individual opinions. Learning motivation is a crucial enabler for academic success [21–23] and learning performance [11, 21].
Learning motivation can be classified as intrinsic and extrinsic. Studies on blended learning often suggest that intrinsic motivation is more effective in learning as students who are intrinsically motivated tend to perform better and complete assignments faster than extrinsically motivated students [11, 25]. However, research has also shown that long video lectures for online learning during the COVID-19 pandemic increased the boredom in learning, and reduced students’ motivation to learn [26].
In engineering education, intrinsic factors such as individual attitudes and expectations can prove to have a more dominant motivating effect in contrast to extrinsic factors such as pulling forces, learning approach, and peer pressure [27]. Yacob and Saman [28] assert that both intrinsic and extrinsic factors contribute in motivating engineering students to learn better. They point out that the intrinsic factors include individual attitude, expectation, and challenging goals, while the extrinsic factors include clear direction, reward and recognition, punishment and social pressure, and competition.
Social presence
Social presence refers to the ability of students in relating, communicating, and forming productive and personal relationships with their peers in the classroom [29]. It is a concept that can be used to examine the social interaction quality of a virtual learning setting [30]. According to Whiteside et al. [31], it is advantageous for institutions to support the integration of social presence into the learning environment as it enriches student learning experience. Several studies also concur that social presence improves student learning satisfaction and performance [30, 32–34].
In the context of students who are new to distance learning, So and Brush [35] suggested that the instructional scaffolding and modelling of social presence behaviours might be required. Beginners of online learning should be assisted not only in establishing and maintaining social presence, but also in reading and making sense of the social presence of others [36]. Instructors could also model strong social presence expectations via teacher immediacy skills when planning online course assessments and activities [32].
Cognitive presence
Cognitive presence is defined as the degree of which online learners can construct and validate meaning according to continuous and critical thinking and communication [37–39]. Studies have found that cognitive presence reinforces critical thinking, evidence-based thinking, knowledge construction and learning experience [40–42]. Aside from teaching and social presences, cognitive presence was found to be the most powerful predictor for perceived learning and satisfaction in soft-pure, soft-applied, hard-pure and hard-applied academic disciplines [12]. Cognitive presence is positively affected by externally-induced motivation through grades and externally-facilitated regulation scaffolding techniques [43].
In the matter of cognitive presence development, Kovanović et al. [44] suggested that quality is more important than quantity when it comes to learning activities as highly metacognitively skilled learners can be just as successful as highly engaged learners. Hence, the lack of utilisation in learning management tools or systems would not necessarily allude to poor cognitive development. Other researchers pointed out that increasing cognitive presence among learners could automatically lead to the increase in their social presence to an extent [45]. In another perspective, online instructions could also emphasise on using social presence as a catalyst for enhanced cognitive presence [46].
TRIZ
TRIZ is a Russian acronym which stands for the theory of inventive problem-solving [47, 48]. It is an analysis, forecasting and problem-solving approach based on logic as opposed to spontaneous creativity which emerged from the investigation of invention patterns in the global patent literature [49–51].
TRIZ improves self-efficacy which is a crucial component in the long-term development of both problem finding and problem-solving abilities [52, 53]. Belski et al. [54] found that engineering students developed significantly better problem-solving skills when learning TRIZ as contrasted with learning other engineering modules in their four-year programme. TRIZ not only positively affects learners’ problem analysis skills, but also improves their creativity and abilities in solution identification, selection, and implementation [16].
TRIZ can be used as a foundation for learners’ knowledge systematisation which is a didactic aspect involving concepts such as system, systemness, systems approach, and system development rules [14]. It is important for educators to harmonise current teaching arrangements with systematic thinking tools such as TRIZ, especially in new curriculums which aim to develop learners’ thinking abilities [55].
Industry talks in higher learning institutions
In principle, industry talks organised in higher learning institutions are lectures or sharing sessions conducted by industry experts for the purpose of improving students’ exposure to the real-world practice. In an industry talk, the industry expert usually discusses important topics of influence over their business or ideas from their professional experience [56]. Students would also gain insights into their future workplace requirements by networking and interacting with the industry expert, and work towards developing applicable skills [57].
In Malaysian engineering programmes, the Engineering Accreditation Council [58] considers industry talks as key components of exposure to engineering practice that should be integrated throughout the engineering curriculum. The exposure to practical experiences via industry talks helps students appreciate their learning and go beyond academics through insights, practical knowledge, applications, and a critical mindset [59]. Industry talks also help students master the essential soft skills in graduate attributes such as responsibility and ethics, lifelong learning, and knowledge on the current issues [60].
Hypotheses development
Numerous researchers have contended that the systematic TRIZ approach and exposure to industry talks can significantly enhance students’ learning, cognitive abilities, and communication skills [14, 59]. Nonetheless, the use of TRIZ and industry talks has never been observed or studied in a blended learning environment. Furthermore, while the relationships among learning motivation, cognitive presence, and social presence have been carefully studied [12, 61], the investigation of their relationships with TRIZ and industry talks have remained unresearched. Owing to the effectiveness of TRIZ in harnessing creativity and inventiveness in teaching and learning, and higher education [62–64], and success of industry engagement activities in engineering education programmes, it would be of interest to investigate how TRIZ and industry talks can be related with the learning motivation, social presence, and cognitive presence of engineering students in a blended learning environment [65–67]. However, as of now, there has yet to be a study that explored such a relationship. Hence, the following hypotheses are proposed:
Methods
Measurement instrument
The hypotheses were tested using a quantitative survey. Most of the survey items pertaining to learning motivation, cognitive presence, and social presence were built upon from the studies of Lim and Richardson [12], Law et al. [11], Kozan [46], and Kozan and Richardson [45]. Items related to industry talks were based on a study from Markom et al. [59] and a specific topic of the course known as intellectual property law. The items on TRIZ were based upon literature studies from Berdonosov [14], and Greenberg [55], and specific TRIZ tools known as function analysis and cause-and-effect-chain (CEC) analysis.
The full list of survey items can be found in the Appendix. The first section comprises the participants’ demographic profile, which includes age, gender, programme and year of study. The second section includes the items classified under learning motivation (LM), social presence (SP), cognitive presence (CP), TRIZ, and industry talks (IND).
A seven-point Likert scale was administered for this study as it is more accurate, more reliable, easier to use, and gives a better reflection of the respondent’s true evaluation in contrast to other Likert scales [68–70]. The internal consistency reliability of the survey instrument was evaluated through the Cronbach’s alpha coefficient. From Table 1, the alpha values suggested that the internal consistency of the survey instrument was high (α> 0.7) for all the variables [71, 72].

A factor analysis was done as well. From Table 2, the factor loading for every item of each variable exceeded 0.6, signifying that each factor extracts an acceptable amount of variance from the variable [73]. To avoid social desirability effects and common method bias, the survey was administered anonymously and online. To assure face validity, the survey was vetted by 2 education experts from different higher learning institutions who are familiar with engineering education, industry engagement activities, and TRIZ.
Factor Loadings for Variables
The survey was shared with all the 98 students who enrolled in a blended learning course on engineering law. The response rate was 100%. The students came from 3 different engineering programmes, namely mechanical engineering, robotics and automation engineering, and telecommunications engineering.
The engineering law course consisted of topics such as introduction to law, contract law, tort, cyber law, intellectual property law, employment legislation, and laws pertaining to engineers. Due to the COVID-19 pandemic and movement control order in Malaysia, the lectures were facilitated online synchronously via Google Meet. Apart from the 40 hours of online synchronous lectures, there were 7 hours of asynchronous learning in the form of pre-recorded videos, infographics, articles, and notes for students to engage with before the lectures.
Digital education tools such as Padlet, Google Docs, and Quizziz were used during lectures to reinforce students’ understanding on the topics, and better prepare them for their group assignments. TRIZ tools such as function and CEC analyses were used alongside these digital tools to help students systematically break down and analyse cases and complex issues pertaining to engineering law. For the topic on intellectual property law, an industry expert from an intellectual property consulting firm in Malaysia was invited to a lecture session.
TRIZ integration into teaching and learning
To spark the interest in learning topics on law among engineering students, a TRIZ technique known as function analysis was used. Students were asked to link the functions of every entity within the Malaysian legal system in a Padlet setting. This technique was used to improve the visualisation and memorising capability of the engineering students about the legal system. Figure 1 shows the Padlet activity. All students were required to participate in completing the function model with the guidance of the instructor.

Padlet Activity on TRIZ Function Analysis (Malaysian Legal System).
The students were also guided on how to formulate engineering contradictions for contract law case studies. One of the cases was adopted from Sobri [74]. The students were requested to type their contradiction statements about the case in a Padlet setting. The technique used in formulating the engineering contradiction was the If –Then –But technique (See Fig. 2). This technique was used so that the students are able to relate better with the details of the case study.

Padlet Activity on TRIZ Technical Contradictions (Contract Law Case Study).
Another TRIZ technique known as the cause-and-effect-chain (CEC) analysis was also taught to students under the topic of employment legislation. The case discussed in Padlet involved the reasoning behind an employee’s surprise to an employment termination. The students were required to ask the question “why, and why else?” until an acceptable root cause is ascertained (See Fig. 3). This technique was used to stimulate the critical thinking ability of students in employment law cases.

Padlet Activity on TRIZ CEC Analysis (Employment Legislation Case Study).
The CEC analysis was also used in other case studies on the laws pertaining to engineers in Malaysia. In the example, the students were required to ascertain the root cause behind the inability of an engineering graduate, who studied a 3-year bachelor of engineering programme overseas, in registering as a professional engineer with a practising certificate in Malaysia (See Fig. 4). The TRIZ technique was used to help the engineering students better understand the requirements to register as a professional engineer and graduate engineer in Malaysia.

Padlet Activity on TRIZ CEC Analysis (Case Study on Laws pertaining to Engineers).
The industry talk was integrated into a topic on intellectual property law. A CEO of an intellectual property consulting group in Malaysia was invited to deliver a 2-hour industry talk on “owning and monetising engineering ideas with intellectual property rights”. The CEO is a patent, trademark and industrial design attorney, a lawyer, and an angel investor. The talk covered how engineers could protect their innovation with the right type of IP, an overview of different categories of intellectual property rights, requirements of patents and patentability, and commercialisation of university intellectual property rights. An intellectual property assignment was created based on the industry talk. The assignment describes a company that is suing another company for a patent infringement. The sued company intends to invalidate the patent. For this intellectual property assignment, the students were required to give their expert opinions on the validity or invalidity of the patent.

Participant demographics
According to the demographics reported in Table 3, the participants were mostly 20 to 23 years of age (about 90%). Males accounted for almost 89%, while females comprised only about 11% of the total participants. Most of the participants were from the mechanical engineering programme (about 58%). Approximately 23% of them came from the robotics and automation engineering programme, while around 18% originated from the telecommunications engineering programme. The majority of them (around 79%) were third year students.

The data for the dependent and independent variables were not normally distributed. Therefore, Spearman’s correlation test was used to assess the strength and direction of association existing among the variables according to the hypotheses.

Notes:
It was found that TRIZ correlated strongly with learning motivation (rs = 0.765,
While TRIZ encourages the ability for self-directed learning and strengthens motivation among learners [75], industry talks expose them to social responsibility and accountability in teams [59]. In the present study, industry talks correlated strongly with learning motivation (rs = 0.750,
The authors of the present study believe that the students were highly motivated due in part to the use of innovative tools and strategies such as TRIZ and industry talks in the course. More often than not, introducing a variety of innovative approaches in teaching and learning tends to improve students’ learning motivation [78–80].
A general regression analysis and ANOVA were performed with a Box-Cox power transformation. The optimised lambda values for all the regression analyses were found to be around 1.1 to 1.3, and were hence rounded to a value of 1. The results of the general regression and ANOVA are summarised in Table 5. The variance inflation factors throughout the model were found to be less than 5 (VIF < 5), which is still within the acceptable range in regard to multicollinearity. The Durbin-Watson statistic was found to be within the normal range (1.5 to 2.5) with regard to positive autocorrelation.

General Regression Model and ANOVA Summary for Learning Motivation, Social Presence, and Cognitive Presence
Notes:
On the whole, it was found that all the independent variables significantly predicted learning motivation, social presence, and cognitive presence. TRIZ was found to be a significant predictor for learning motivation [β= 0.571, t(95) = 5.413,
Y1 = 0.690 + 0.568 X1 + 0.301 X2
Y2 = 0.626 + 0.687 X1 + 0.213 X2
Y3 = 0.436 + 0.581 X1 + 0.334 X2
Where Y1 –Learning Motivation; Y2 –Social Presence; Y3 –Cognitive Presence; X1 –TRIZ; X3 –Industry Talks
The present research contends that the inclusion of TRIZ and industry talks in teaching and learning significantly affects learning motivation, social presence, and cognitive presence with an explained variability of around 70 to 80%. This finding could be attributed with the strong influence of TRIZ on students’ creativity and problem-solving abilities [16, 53], and positive impacts of industry talks on students’ practical and lifelong learning [59, 60]. Thus, H7 is supported.

Notes:
This finding provides some general evidence that the integration of TRIZ and industry talks in a blended learning environment enhances the achievement of POs. The evidence is consistent with findings from several studies that combined the use of various innovative techniques and strategies to enhance programme and learning outcomes [16, 81–83].
In addressing the research question of this study, the researchers confirm that TRIZ and industry talks are positively and significantly correlated with the learning motivation, social presence, and cognitive presence of engineering students in a blended learning setting. The findings of this study support the concept of including TRIZ and industry talks along with other essential teaching and learning variables to reinforce learning performance in a blended learning environment. Such a concept could reduce some of the challenges in implementing blended learning. If imparted from an analogical viewpoint, the adoption of TRIZ and industry talks in teaching and learning could help turn blended learning into a “sweet instead of bitter pill to swallow” for both learners and educators in spite of the challenges faced during the COVID-19 pandemic. Several specific conclusions can be drawn from this study: The use of TRIZ and industry talks with digital education tools potentially motivated students to learn, thus improving their cognitive presence, social presence, and also achievement of POs. While correlations between industry talks and other variables were strong, the slightly low correlation between industry talks and social presence was perhaps due to the limited scope of topics covered by the talks and assignment. The inclusion of TRIZ and industry talks significantly affected learning motivation, cognitive presence, and social presence on the whole, with explained variations of about 70 to 80%.
The findings of this research should be generalisable across courses under the soft-applied disciplinary areas, such as health and social care, modern languages, business and education. Concerning the directions for future research, further studies that explain the moderating and mediating effects of TRIZ and industry talks on the other variable relationships could be explored to reinforce the findings of this research. Further investigations regarding control and experimental groups could be done to compare the performance between a class taught in a traditional setting and a class exposed with TRIZ knowledge and industry talks.
Limitations
Although the sample size of this study was sufficient for the researchers to run the required analyses, it was comparatively lower than the sample size used for other similar studies that investigate factors affecting students’ learning motivation in blended learning settings. The researchers intend to extend their study to other blended learning courses in the future. This study emphasised on the participation of engineering students in an engineering law course, which is categorised under the soft-applied disciplinary area. Admittedly, the generalisability of this study’s results might be somewhat inexact in the context of other hard-pure, hard-applied, or soft-pure disciplines. Thus, future research should involve data collection from courses of varying disciplinary areas.
Implications
The findings of this research provide important implications for online learning instructors and instructional designers. The inclusion of TRIZ and industry talks in teaching and learning could assist instructors in addressing the self-regulation challenges faced by students in an online learning environment [10]. In particular, the use of TRIZ tools and involvement of industry experts for talks might complement the use of prompts in supporting students’ self-regulation [84], which could increase online student engagement. For instance, the aspect of metacognitive prompts which requires reflection on online learning contents [85] can be systemised and given form using TRIZ tools such as function analysis, CEC analysis, technical contradictions, and inventive principles. Furthermore, in the midst of employment uncertainties due to the COVID-19 pandemic, linking students with industry experts through talks not only gives them a simulated experiential learning experience, but also confidence in the context of preparing them for employment as engineers [86].
