Abstract
In this study, we investigated Texas teachers’ perceptions of instructional coaches’ (ICs) practices that improve professional learning communities (PLCs) to enhance teachers’ instructional capacities. The study’s participants included 67 teachers from rural, urban, and suburban school districts across the state of Texas. They enrolled in a virtual professional development (VPD) module related to improving instruction in high needs schools. Data were collected from participants via an open-ended survey. To answer the study research question, we employed a qualitative phenomenological research approach. Findings indicated that teachers perceived ICs can perform two main types of practices that contribute to enhancing PLC meetings: (a) practices for creating a safe PLC learning environment and (b) practices in PLCs for enhancing teachers’ instructional capacities. Our findings add to the literature providing the first empirical study in which researchers investigated teachers’ perceptions about ICs’ practices within PLCs.
Keywords
Over 20 years ago, Hord and Southwest Educational Development Laboratory (1997) indicated several design elements for professional learning communities (PLC) as follows: (a) Supportive and shared leadership, (b) Shared values and vision, (c) Collective learning and application of learning, (d) Supportive conditions (physical and human capacities), and (e) Shared practice. Dufour (2004) added to information about PLCs and noted they should emphasize a tool for educators with three big ideas: (a) an emphasis on learning, (b) developing a culture of collaboration, and (c) a focus on results (pp. 6, 11). More recently, Irby (2021) challenged the traditional definitions of the PLC, but did not advocate removing anything previously recommended by Hord and/or Dufour. Rather, Irby suggested intentionally adding the following premises to the definitions of PLCs: (a) instructional capacity of teachers is of primary importance in PLCs as a component of their learning, (b) infusion of new information into PLC discussions is required; without it, the learning in professional
Dufour, along with others, found that PLCs can play an important role in enhancing teachers’ instructional capacities (DuFour & Mattos, 2013; Marsh et al., 2015). Evidence collected on well-structured PLCs has indicated that they provide teachers with opportunities to collaborate with each other and with other professionals in ways to enhance their instruction (Farley-Ripple & Buttram, 2014). Though there are studies that include the examination of PLCs
In this study, we sought to identify practices that ICs engage in during PLCs which may enhance teachers’ instructional capacities as perceived by teacher participants in the study. The participants included 67 teachers across Texas who were enrolled in virtual professional development (VPD) on the topic of PLCs, which was provided by Project Massive Open Online Individualized Learning (MOOPIL) at Texas A&M University in Texas.
Literature Review
We reviewed literature from the ERIC, JSTOR, and Education Source databases related to practices that ICs perform in PLCs as related to enhancing teachers’ instructional capacities. Keywords we used were: instructional coaches, coaching, professional learning communities, or PLCs. About 25 papers were discovered and reviewed in one search and 321 were found in the second search. In the literature we reviewed, we found information on how ICs helped individual teachers to analyze student achievement data and make changes in their instruction as needed (Farley-Ripple & Buttram, 2014; Marsh et al., 2015; Thornton, 2015). We also found information on how well-structured PLCs provided teachers with opportunities to collaborate with other teachers on instruction, which contributed to improving the quality of teaching and learning (Irby et al., 2020; De Neve & Devos, 2017; Lee et al., 2011). However, we were not able to find literature investigating ICs’ practices in PLCs. The one study that we found about IC coaching PLCs was by Voelkel et al. (2021), who investigated the perceptions of district leaders (principals, ICs, and district-level leaders) on the procedures a particular district followed to shift the role of ICs from coaching individual teachers to coaching PLCs. However, the authors did not explore practices ICs may perform in PLCs.
To the best of our knowledge, our empirical study is the first to investigate the perceptions of teachers related to ICs practices in PLCs that could contribute to improving the quality of PLCs and teachers’ instructional capacities. This makes what the 67 participant teachers in this study shared on ICs’ practices in PLCs (whether actual ICs’ practices participant teachers observed in PLCs of their schools or ICs’ practices teachers believe are needed to improve the quality of PLCs) a unique contribution to the literature related to ICs practices in PLCs.
Since we did not find practices of ICs in PLCs, we divided our review of the literature into two sections as follows: (a) instructional coaches’ practices with individual teachers and (b) characteristics of PLCs that enhance teachers’ collaboration. The findings in this related literature may help to inform the actions of ICs as they engage in PLCs.
Instructional Coaches’ Practices With Individual Teachers
Coaching is a formal and structured professional relationship in which a coach targets specific skill(s) to develop and strengthen in a coachee over a specific time period (Irby, 2018). Although districts put notable emphasis on instructional coaches, though not specifically related to PLCs, with the specific task of helping teachers improve their teaching quality, they often do not specify clear descriptions of the coaches’ roles or responsibilities in attaining this goal (Galey, 2016). Evidence collected about ICs’ influence on individual teachers showed that ICs performed some practices that had a positive impact on enhancing teachers’ instructional capacities, mainly assisting with data analysis and teaching strategies (Farley-Ripple & Buttram, 2014; Marsh et al., 2015; Thornton, 2015). However, there was not strong evidence in the literature about which structured roles ICs play in PLCs with large groups of teachers and how those roles contributed to PLCs’ success enhancing teachers’ capacities for improving student achievement (Galey, 2016; Voelkel et al., 2021). This is because most of the studies that investigated ICs roles were qualitative in nature and restricted to case studies of individual schools (Galey, 2016). Hopkins et al. (2018) highlighted the importance that ICs foster trust in their professional relationship with teachers. Once established, this trust motivates teachers to take leadership roles at their schools and provide instructional assistance to other colleagues (Hopkins et al., 2018).
Assisting teachers in analyzing and using student data
Analyzing student achievement data and making decisions on instructional practices is not an easy task for many teachers (Farley-Ripple & Buttram, 2014; Marsh et al., 2010, 2015). There is evidence that ICs
The Delaware Department of Education had an initiative to assist teachers in analyzing and using student achievement data to inform instructional changes in Delaware (Farley-Ripple & Buttram, 2014). They mandated 90-minute PLCs in all schools, focusing the core of PLCs on analyzing data, providing teachers with data coaches in PLCs, hiring a data center to work on finding data and making them accessible to teachers so they could obtain student performance reports. In the four elementary schools from the two districts that participated in the study, ICs worked with teachers in PLCs on data analysis in only one school. However, they did not seem to make connections related to how these data could inform changes in instruction. Thus, those procedures were not perceived by teachers as sufficient to help them make major changes in their instruction (Farley-Ripple & Buttram, 2014). Understanding student data was not enough; teachers also needed assistance to make instructional decisions and to modify their instruction to help improve student achievement (Farley-Ripple & Buttram, 2014; Marsh et al., 2010).
The ability to analyze data is very important for a professional teacher; however, the literature we were able to find did not address an IC working
Characteristics of PLCs That Enhance Teachers’ Collaboration
In addition to the definitions noted previously, PLCs are described in the literature as professional meetings that allow interactions, discussions, and reflections among teachers on issues of teaching concern such as lesson planning, teaching strategies, and best practices (DuFour et al., 2008; DuFour & Mattos, 2013; Hord & Southwest Educational Development Laboratory, 1997). Many scholars have highlighted the importance of PLCs in helping teachers improve their teaching capacity (Brodie, 2013; DuFour et al., 2008; Marsh et al, 2015; Stoll et al., 2006). For PLCs to be beneficial to instruction, they need to be well-structured and provide opportunities for professional collaboration among teachers (Brown et al., 2018; Chua et al., 2020; Coburn & Russell, 2008; Jones-Goods, 2018). PLCs without a clear purpose and those in which some teachers may just tell stories about their classrooms are not expected to inform discussions or provoke deep reflection about instructional practices (Coburn & Russell, 2008). Pirtle and Tobia (2014) found that actually determining a clear purpose for PLCs helped to make teachers’ interactions and activities more goal-oriented.
There are a number of PLC characteristics that help enhance teachers’ instructional capacities (Scott et al., 2011; Teague & Anfara, 2012). For example, fostering trust among PLC members contributed to creating a safe learning environment for teachers to engage properly in PLC through conversation, asking questions, and reflecting on their teaching (Thornton, 2015). Antinluoma et al. (2021) identified a number of positive characteristics in schools’ relationships that contributed to advancing professional relations among teachers at four schools and in their PLCs. These characteristics included being flexible, open, supportive, professional, and tolerant.
Clear values and goals for PLC meetings
Establishing a framework of clear values and goals for PLC meetings ensures good communication between teachers (Walkowiak, 2016) and increases the meetings’ effectiveness and focus on improving student learning (Pirtle & Tobia, 2014; Stoll et al., 2006). In his qualitative case study on one high school, Jones-Goods (2018) found that structured PLCs with scheduled meeting times and clear purposes for teachers’ collaboration were perceived by teachers as contributing to advancing their instructional capacities. Similar to this, Pirtle and Tobia (2014) explained that for PLCs to be effective they need to have a clear focus on increasing teachers’ collaboration in ways that advance their self-reflection. These goals of collaboration and self-reflection are necessary to improve classroom instruction, which contributes to improving student achievement.
Collaboration among teachers on instruction
Many scholars reported that teachers collaborating on matters of instruction contributes to the improvement of teachers’ teaching practices (e.g., Antinluoma et al., 2021; Brown et al., 2018; De Neve & Devos, 2017; Farley-Ripple & Buttram, 2014; Jones-Goods, 2018; Lee et al., 2011). Brown et al. (2018) concluded from reviewing the literature that focusing PLCs on identifying students’ learning needs and improving their learning contributes to enhancing both teachers’ pedagogical capacities and student achievement. Similarly, Lee et al. (2011) found that providing teachers with opportunities to ask questions and solicit feedback during PLCs increases their efficacy and commitment to students. Aligned with that, De Neve and Devos (2017) found that dialogue between teachers during PLCs, whether on content knowledge or pedagogy, assists new teachers, in particular, in differentiating their instruction.
Antinluoma et al. (2021) argued that when teachers collaborate on lesson planning and co-teaching, they have better opportunities for professional discussions on improving the quality of instruction. Though dialogue and planning for lessons
Research Question
One research question guided our study: As perceived by teacher participants, what practices can ICs engage in during PLCs which may enhance teachers’ instructional capacities?
Theoretical Framework
To interpret the findings of the study, we used theoretical assumptions of the theory of organizational learning (OL; Fiol & Lyles, 1985; Leithwood et al., 1998) and of the zone of proximal development (ZPD) from Vygotsky’s (1978) sociocultural theory. The theory of OL introduced the positive impact of the different learning levels within an organization: individual, group, and entire organization, and how they contribute to increasing the strength and competitiveness of organizations (Fiol & Lyles, 1985). Drawing on the theory of OL, Leithwood et al. (1998) explained how this theory can help in understanding why valuing different levels of learning at schools, as organizations, and creating PLCs, could contribute to advancing the effectiveness of those schools. The theory of OL, thus, is appropriate for the study as it helps in understanding how the surrounding beliefs that the leadership team, instructional coaches, and teachers value in relation to the importance of learning for organizational effectiveness to facilitate their support and contribution to PLCs (Figure 1).

Theoretical framework.
On the other hand, in the ZPD, Vygotsky (1978) and Verenikina (2003) explained how individuals can master skills by receiving scaffolding assistance that helps them to move from their current learning stage to the learning stage they want to achieve. Although the ZPD was originally used by Vygotsky (1978) to interpret the social environment for child development, scholars such as Bonk and Kim (1998) asserted that the ZPD can also be applied to interpret skills development for adults.
The ZPD is appropriate for the study as it helps in understanding how the practices of ICs in PLCs, perceived as effective by the teacher participants in the study, could provide teachers with the instructional scaffolding they need to enhance their teaching and level up their instructional capacities. This scaffolding assistance could take several forms of social interactions between teachers and ICs, such as questioning, feedback solicitation, inquiries, discussions, and reflections that usually occur during PLC meetings. Teachers use the scaffolding assistance of instructional coaches and translate their data analysis, instruction modeling, and suggested feedback into more effective teaching strategies for their students.
Methods
Research Approach
A phenomenological research approach (Creswell, 2012; Creswell et al., 2007) was employed to identify teachers’ perceptions of ICs’ practices that contribute to improving PLCs to enhance teachers’ instructional capacity as perceived by teacher participants in the study. A phenomenological approach can help researchers analyze the perceptions of multiple participants with the goal of understanding a certain phenomenon (Creswell, 2012; Creswell et al., 2007). This approach was appropriate for a study analyzing what 67 teachers perceived as practices of ICs as they work in PLCs.
Participants
The participants of this study included 67 K-12 teachers, 56 females, and 11 males. Teachers were recruited from rural, urban, and suburban school districts across the state of Texas. The teachers taught a range of subjects including English/Language Arts, Mathematics, Science, and Social Studies. Each teacher was enrolled in a virtual professional development (VPD) module related to improving instruction in high-needs schools. To ensure participant confidentiality, we used pseudonyms to replace the real names.
Data Collection
We collected data for the study from the responses of 67 teachers to an online qualitative survey prior to their participation in a VPD. The survey included seven questions: (a) How might the instructional coach be involved in PLCs?; (b) What might the IC do differently to encourage a safe PLC environment of respect and trust and engage all members?; (c) How might learning be structured to provide differentiated support and learning for all team members?; (d) How might engaging in intentional discourse during the PLC foster professional learning?; (e) How might learning be structured to provide differentiated support and learning for all team members?; (f) How might engaging in “intentional discourse,” rather than avoidance, foster professional learning?; and (g) How might the professional learning community members ensure that their learning remains student-focused?
Data Analysis
Two members of the research team read teachers’ responses to the survey questions in order to make sense of the data collected. Then, the
Trustworthiness and Credibility of the Study
To advance the trustworthiness and credibility of the study, the research team employed two major techniques: investigator triangulation (Krefting, 1991) and low inference descriptors (Johnson, 1997). For the investigator triangulation, two members of the team worked with NVivo 11 Software to identify the emerging sub-themes, which were validated by a third member (Krefting, 1991). Triangulation of investigators is an effective qualitative research technique to reduce bias that might occur in studies with a single author. Triangulation is especially useful when the researchers are from different backgrounds, which is the case in our study (Krefting, 1991). The third technique, low inference descriptors (Johnson, 1997), refers to the researchers using participants’ actual wording from their specific responses to the qualitative survey questions.
Findings
We report the findings of the study with the emergence of two themes and six sub-themes of ICs’ PLC practices associated with perceived effective IC practices in PLCs. The two sub-themes were determined to be: (a) ICs create and sustain a safe PLC learning environment and (b) ICs assist teachers in enhancing their instructional capacities. The six sub-themes are shown in Figure 2. Two were identified under the theme of ICs creating and sustaining a safe PLC learning environment and four sub-themes were identified under the theme of ICs assisting teachers in enhancing their instructional capacities. Each sub-theme with low inference descriptors is shared.

Emerging themes and sub-themes from data analysis.
IC Practices in PLCs: Create and Sustain a Safe PLC Learning Environment
As shown in Figure 3, teachers’ perceptions of ICs’ practices for creating and sustaining a safe PLC learning environment were divided into two sub-themes: (a) establish norms and rules for PLC meetings and (b) foster trust and mutual respect among PLC participants.

Perceived ICs’ practices for creating and sustaining a safe PLC learning environment.
Establish norms and rules for PLC meetings
Forty-Five teachers believed that one of the most important ICs’ practices to create and sustain a safe PLC environment is to establish norms and rules for PLC meetings. For example,
Foster trust and mutual respect among PLC participants
Nineteen participants highlighted fostering trust and mutual respect among participants as important practices of ICs to create a safe PLC environment. For example,
To attain trust in PLC meetings,
Demonstrating respect for teachers and their opinions was also perceived as an important key to gaining teachers’ trust. Teacher 34 stated, “
IC Practices in PLCs: Enhance Teachers’ Instructional Capacities
The second type of ICs’ practices perceived by the participants as effective in PLCs were those associated with advancing teachers’ instructional capacities. As shown in Figure 4, the participants reported four practices: (a) assist teachers in analyzing student data, (b) share instructional strategies and ideas with teachers; (c) facilitate collaboration among teachers on instruction, and (d) engage teachers in intentional discourse rather than avoidance.

Assist teachers in analyzing student data and improving their instruction in PLCs
Twenty-five teachers believed that ICs can play a remarkable role in assisting teachers in understanding, analyzing student achievement data, and utilizing best instructional practices that would work for students. For example, The
The participant also explained how ICs can help teachers identify patterns and trends from analyzing their student data. For example,
Helping teachers address low performing students by analyzing their data was another role the participants in the study highlighted as important practices of ICs in PLCs. For example,
Share instructional strategies and ideas with teachers in PLCs
Fifty-three teachers highlighted the importance of ICs’ practices in PLCs related to sharing instructional strategies and ideas that worked for them with other teachers.
Similar to this,
Facilitate collaboration among teachers on instruction in PLCs
Sixty teachers indicated that facilitating collaboration among teachers on instruction is one of the most important practices of ICs in PLC. They explained how ICs can help teachers focus their dialogues and conversations on instruction to attain PLC meeting goals.
Utilizing expertise of experienced teachers to help new teachers enhance their teaching was also among the effective practices highlighted by teacher participants in the study.
Engage teachers in intentional discourse in PLCs
Fifty teachers highlighted the role of ICs in engaging teachers in intentional discourse to discuss teaching issues teachers might have with the goal to enhance their instructional capacities. This is because participant teachers perceived intentional discourse as an effective tool ICs can use in PLCs to help teachers overcome avoidance and have purposeful communication with each other. For example,
Teacher participants indicated that intentional discourse rather than avoidance can help teachers participating in PLCs to improve student achievement.
Intentional discourse seemed to have been perceived by teachers as effective in addressing particular issues such as misconceptions teachers may have about data analysis in PLCs as well as issues associated with using power dynamics by school leaders to ensure teachers’ participation in PLCs. For example,
Discussion
The purpose of this qualitative study was to identify practices that ICs engage in during PLCs which may enhance teachers’ instructional capacities as perceived by participants in the study. The study sample is diverse, including 67 Texas teachers of different ethnicities, subjects, and grade levels. This made participants able to share a wide range of perceptions regarding actual or potential IC practices in PLCs they believe can enhance teachers’ instructional capacities. Findings of the study are considered an addition to the literature related to practices ICs can perform in PLCs to enhance teachers’ instructional capacities as perceived by participants. This is because we did not find previous literature on this particular topic. All the studies we found, as previously described in the literature section, addressed either ICs practices to support individual teachers (Hopkins et al., 2018; Hord & Southwest Educational Development Laboratory, 1997; Marsh et al., 2010, 2015; Pirtle & Tobia, 2014; Stoll et al., 2006; Walkowiak, 2016) or studies on the characteristics of PLCs that contribute to enhancing teacher instructional practices (Antinluoma et al., 2021; Brown et al., 2018; De Neve & Devos, 2017; DuFour et al., 2008; DuFour & Mattos, 2013). However, we did not find any studies investigating the perceptions of teachers, or any practitioners at the school or district levels, of the ICs’ practices in PLCs as described in this study. The only study we found was Voelkel et al. (2021). They investigated the perceptions of district leaders (principals, ICs, and district-level leaders) on the procedures a particular district followed to shift the role of ICs from coaching individual teachers to coaching PLCs. While there were studies that investigated ICs’ practices with individual teachers and other studies that explored characteristics of PLCs contributing to enhancing teachers’ practices, this is the first study to investigate ICs’ practices in PLCs, to the best of our knowledge.
To better interpret the findings of our study, we employed a theoretical framework based on two theories: the theory of OL (Fiol & Lyles, 1985), particularly at the school context (Leithwood et al., 1998); and the ZPD assumptions (Verenikina, 2003; Vygotsky, 1978). We combined theoretical assumptions from the two theories to shed light on two levels of learning support that may exist at schools, as organizations. These two levels can be described based on the level of support provided to teachers on instruction as an outer level and an inner level of learning support. To emphasize this, the outer level of learning support describes the general school level support when all school members, including leadership team, teachers, parents, and students, value learning and realize its importance in increasing organizational strength and competitiveness as described in the theory of OL. While this advances the learning environment of the school, it still does not provide specific instructional support to teachers. As for the inner level of learning support, it describes how ICs’ PLC meeting practices designed to enhance teachers’ instructional capacities can provide a focused instructional support to teachers.
Participants in the study shared two main types of practices ICs can perform in PLCs which can contribute to enhancing teachers’ instructional capacities. Under each of the two types, we were able to identify more specific practices. The first main type is
Informed by the previous studies we conducted on PLCs for teachers and leadership teams (Irby et al., 2017; Irby, 2018, 2021), we agree with participant statements related to how trust among teachers in PLCs is important for professional learning. This is simply because if teachers, particularly new and novice teachers, did not feel that trust, they would not feel comfortable sharing ideas with or soliciting feedback from other professionals in PLCs. This would affect collaboration negatively and would definitely limit opportunities for professional learning. Thus, participants in the study believed that creating a safe learning environment is a basic practice of ICs in PLCs upon which other practices might be established.
The other main practice perceived by the participants was
Intentional discourse was perceived as one of the most effective of ICs’ practices to enhance teachers’ instructional capacities in PLCs. The participants believed that ICs performing this particular practice effectively results in maximizing the functionality of other IC practices in PLCs. In other words, ICs successfully utilizing intentional discourse to enhance teachers’ accountability for improving student achievement helps create a safe PLC learning environment. Creating a safe PLC environment informed by trust among all professionals participating in PLCs helps to overcome the sense of avoidance some teachers might have in PLCs. This trust also advances collaboration between teachers on instruction, which contributes to enhancing teachers’ instructional capacities and improving student achievement.
Conclusion
While some studies investigated ICs’ practices with individual teachers and other studies explored characteristics of PLCs that contribute to enhancing teachers’ practices, this is the first study to investigate ICs practices in PLCs, to the best of our knowledge. Participants shared two types of practices: the first was intended by ICs to create and sustain a safe PLC learning environment. The participants highlighted two specific practices, including to establish norms and rules for those meetings and to foster trust and mutual respect among PLC members. The other type of ICs’ practices the participants focused on was instructional support that ICs can provide to teachers in PLC meetings. Particularly, participants reported four specific practices, including to assist teachers in analyzing student data to improve their teaching practices, share instructional strategies and ideas, encourage collaboration among teachers on instruction, and engage teachers in intentional discourse.
In these four specific practices, the participants expressed the remarkable roles ICs can play to facilitate collaboration among teachers on instruction, such as to encourage experienced teachers to share strategies and ideas that worked for them in their classrooms with other teachers attending PLC meetings. The participants also believed that ICs are important in PLCs as they support reflections on ideas and strategies, whether they provide their own reflections or they encourage other professionals to share their thoughts and reflections in a mutually respectful PLC learning environment ICs created.
In many ways, the participants’ perceptions about ICs’ practices in PLCs to enhance teachers’ instructional capacities as highlighted in our study is a unique contribution to the literature in this area. We posit this because while district and school leaders rely on ICs to help teachers improve their instructional practices, the roles those ICs are expected to play in PLCs are not clear enough. For ICs to meet expectations of school and district leaders, ICs’ roles need to be clearly framed and supported by research-based evidence. This increases the importance of our study as we explore and report effective practices ICs play, or are expected to play, in PLCs to enhance teachers’ instructional capacities as perceived by practitioner teachers. To build on this work, we invite colleague researchers to further investigate ICs’ practices in PLCs from the perspectives of other professionals including school and district leaders, in addition to the ICs themselves. We hope this can provide better understanding of those important practices as they help teachers promote their instructional practices, which ultimately contribute to improving student learning and achievement.
Findings of the study can help district leaders develop guidelines for practices of ICs to use in PLCs. We developed a number of recommendations for district and campus leaders to consider as they work to develop ICs who lead PLCs on campuses. We believe these recommendations can help ICs advance the effectiveness of their PLCs related to enhancing teachers’ instructional capacities:
Set clear goals and objectives for PLCs informed by teachers’ and students’ instructional needs.
Establish communication rules/protocols to facilitate communications among teachers and between teachers and ICs.
Determine expectations and responsibilities of ICs and teachers in PLCs.
Involve teachers participating in PLCs in decision-making related to PLC goals, activities, resources, schedules, and outcomes.
Introduce intentional discourse as a framework for PLCs, compare it to avoidance, and share examples of the research findings on how intentional discourse can serve as an effective practice of ICs in PLCs.
