Tracking Active Learning in the Medical School Curriculum: A Learning-Centered Approach.

BACKGROUND: Medical education is moving toward active learning during large group lecture sessions. This study investigated the saturation and breadth of active learning techniques implemented in first year medical school large group sessions.
METHODS: Data collection involved retrospective curriculum review and semistructured interviews with 20 faculty. The authors piloted a taxonomy of active learning techniques and mapped learning techniques to attributes of learning-centered instruction.
RESULTS: Faculty implemented 25 different active learning techniques over the course of 9 first year courses. Of 646 hours of large group instruction, 476 (74%) involved at least 1 active learning component.
CONCLUSIONS: The frequency and variety of active learning components integrated throughout the year 1 curriculum reflect faculty familiarity with active learning methods and their support of an active learning culture. This project has sparked reflection on teaching practices and facilitated an evolution from teacher-centered to learning-centered instruction.

Introduction

Over the past decade, reform efforts in medical and health care education curricula have emphasized the importance of active learning (AL) and technology to improve student engagement and critical thinking skills.[1-5] Key medical education conferences, such as the International Association for Medical Science Educators, have included workshops and instructional guides to improve AL techniques.[6] Other visionary higher education organizations such as EDUCAUSE prescribe AL expressly designed for the millennial generation and beyond.[7,8] Although much has been written about AL, there is a gap in the literature regarding medical schools tracking the saturation of these activities in undergraduate medical curricula.

What is AL? AL is an umbrella term[9,10] that embraces a variety of teaching and learning techniques. These include case-based learning, experiential learning,[11] peer problem solving,[12] and project-based learning.[13] Popular Technology-Enhanced Active Learning (TEAL) media include audience response,[14] vodcasts,[15] virtual patient simulation,[16] and online games.[17] New media include mediated immersion platforms for the current neo-millennial generation, such as virtual reality,[18] and wearable technology.[18]

Active learning represents a shift away from exposition instruction that has a tendency to render learners bored or passive.[19-21] Students take responsibility for their learning by engaging in activities or discussion in class. This method emphasizes higher-order thinking and often involves group work.[4] Well-designed AL lessons have been found to be effective for maximizing learning,[4,9,22] engagement,[23] peer collaboration,[24] and evidence-based medicine.[5,21]

Although AL is widely recommended for medical education, it is common wisdom that not every instructor is comfortable or expert in this approach to instruction. A 2011 survey of faculty at all US colleges of pharmacy[5] suggested that faculty who spend more time teaching are more inclined to use AL techniques. There is a trend for newer institutions and younger faculty to use AL. Despite the advantages, faculty are sometimes hesitant to transform teaching practice due to beliefs, such as needing to cover all pertinent and available material.[25]

What is learning-centered education (LCE) at the classroom level? Learning-centered education[10,13,26] is part of a wider trajectory of curricular and pedagogical reform in higher education,[26] “has its roots in constructivism and context-based theories,” and places emphasis on learning communities, integration, diverse pedagogies, and learning outcomes.[26] Consistent with AL, the goal of the learning-centric model is to train students to be proactive partners in the learning progression: to lean in and engage. Learning-centered education works well for medical education because through situated cognition,[27] students develop professional competency.[28] In reviewing LCE literature, it appears that rich, effective learning for medical students happens under certain conditions, as follows:

Real-world relevance. Medical students are adult learners, motivated by goals and tasks relevant to them, or that have real-world application.[11] In presenting content, instructors emphasize the relevant, high-yield tasks and correlate concepts to clinical applications.

Competency based. Data-driven or competency-based education approaches such as milestones[29] support student-directed learning. Instructors design learning following the cycle: objectives-teach-assess, accentuating authentic performances and frequent feedback.[10,30] After instruction, faculty review learning performance data in a systematic manner[31] to improve learning and delivery.[13] Students take a proactive part in the learning cycle[10,30]—engaging actively, self-monitoring, responding to feedback, and adapting to new learning challenges.

Collaboration. Peer collaboration, sometimes referred to as relational, cooperative,[13] or team-based learning,[2] emphasizes cocreation of knowledge, problem solving in teams, respect, cultural competence, and participatory engagement.

Deliberate practice. To progress from novice to expert, medical students need ample opportunities to digest theoretical concepts and practice new skills,[29,32] with instructive feedback as they progress.

Technology/multimedia. Modern medical education environments integrate current learning technologies and new media.[33] This results in increased engagement, enhanced collaboration, real-world application, clinical decision making, distance training, learning analytics,[1] and swift feedback.[17]

Aims

The aims of this study were to measure the nature and saturation of AL teaching methods in large group (LG) sessions and investigate the relationship between AL components and learning-centered attributes. Research questions were as follows:

Which AL techniques were used and to what degree?

What percent of the Medical School, Year 1 (MSI) LG curriculum has an AL component?

Was the AL taxonomy (Table 1) effective for tracking AL?

Methods

Setting and participants

The setting for this study was an American Osteopathic College of Medicine (COM) located in the Southwest United States. Participants were 20 medical school faculty responsible for teaching a series of systems-based courses to a cohort of 108 first year medical students.

Research design

This study employed a sequential, explanatory mixed methods design in the tradition of a retrospective curriculum evaluation,[39] supplemented by focused interviews with 20 faculty. The curriculum reviewed in 2017 included lesson content for LG sessions taught during first year medical school (MSI) in academic year 2015-2016, but excluded lessons for 3 other concurrent curriculum strands that conventionally rely on experiential or AL: Medical Skills, Anatomy Lab, and Osteopathic Principles and Practice. The university’s Institutional Review Board exempted this study.

Data collection process

Data collection was an 8-step process, provided in detail here so other institutions may replicate this study:

Step 1. Study authors coded each of the 25 learning activities listed in the taxonomy entitled AL Techniques with an alpha code (Table 1).

Step 2. The school’s curriculum manager (CM) conducted a retrospective review of the MSI 2015-2016 LG curriculum, by accessing the MSI weekly academic calendar in Google Calendars, downloading print copies of the weekly course schedule for each of 9 consecutive systems-based courses, and finally shading the LG sections of each day in the week.

Step 3. The CM accessed the associated learning modules for each course in the Blackboard learning management system (LMS) to review content and delivery format for each hour-long lesson.

Step 4. Using the weekly course schedule calendar printouts, the CM used the Taxonomy to assign a code for any AL techniques, evidenced by the content posted in the LMS for each hour of each day of instruction recorded in the course content notes. Some techniques were multiple coded using the simultaneous coding[40] method. For example, for a given 1-hour LG session, the same activity, such as an electronic, case-based game could be multiple coded: (1) game, (2) TEAL, and (3) case-based instruction. Each of those 3 separate components would be counted in the total frequency count for AL components for 1 AL session. This increased the count of AL components for the entire academic year.

Step 5. The CM conducted individual, consented, semistructured interviews with 20 faculty members involved in teaching 9 MSI courses (see Supplementary Appendix 1 for the interview protocol). This process involved reviewing the Taxonomy and then discussing each LG hour of each course taught by that instructor. In this regard, the review of past lessons functioned as a self-evaluation for each instructor.

Step 6. The CM tallied the frequency of AL components per each 1-hour LG session.

Step 7. The CM tallied the AL technique codes by course.

Step 8. After completing the interviews, the CM debriefed with the research team regarding faculty interest and level of participation in the interview sessions.

Materials and instruments

Taxonomies are helpful to educators, as they “assist with categories and distinctions, which then draw attention to ideas.”[41] Furthermore, taxonomies provide definitions that help to operationalize variables in education research.[41] Earlier AL matrices have been proposed by AAMC,[35] Wolff et al,[21] and Stewart et al,[5] but the Taxonomy entitled AL Techniques (Table 1) was developed through the COM’s TEAL Committee and ratified through faculty consensus. Over the past 7 years, many of the AL techniques listed in the Taxonomy were tested with students through prior studies at this institution.[17,23,24,43] It is apparent from the results of these studies that these learning experiences provided the opportunity for students to be proactive, engage, critically think, collaborate, and measure their own progress through immediate feedback.

LCE attributes

The authors identified 5 constructs (attributes) associated with LCE using the following process. Members of the authorship team reviewed the literature and achieved a consensus regarding 5 key attributes of LCE at the classroom level. The authorship team then independently mapped each AL technique to 1 of the 5 attributes. Next, researchers compared results to develop consensus codes for Table 2.

Table 2.

Attributes of learning-centered education, as applied to learning activities.

Attribute	Description of learning activity	Color
1. Real-world relevance	Demonstrates the clinical relevance of the material, including clinical decision making, public health, or social determinants	Purple
2. Competency based	Allows learner to assess progress through frequent feedback or rich mentorship	Red
3. Collaboration	Focuses on consensus, teamwork, peer discussion, consensus decisions, and respectful communication	Blue
4. Deliberate practice	Provides opportunities to memorize, rehearse, review, study, and digest new concepts in the pursuit of critical thinking	Green
5. Technology/multimedia	Integrates health information technology, informatics, bioinstrumentation, or multimedia to introduce a more 3D experience, electronic media (vodcasts, electronic games, videoconferencing, EHR, virtual simulation, electronic databases, mobile apps, etc)	Yellow

Some large group sessions were multiple coded; for example, for a given 1-hour LG session, a professor introduces an electronic, case-based game. This activity would be assigned 3 codes: (1) game, (2) TEAL, and (3) case-based instruction.

Results

Active learning components implemented most frequently were as follows:

Discussion/debate (183);

Case-based instruction (121);

Audience response (86);

Formative quizzes (84);

Demonstration (60).

Active learning components implemented least frequently were as follows:

Annotations or notes (1);

Learning stations (2);

POPS (Patient-Oriented Problem Solving) cases (5);

Oral presentations (by students) (6);

Interactive (online) modules (6).

To better visualize saturation of AL components, Figure 1 presents the data from Table 2 in a pie graph format. In terms of breadth and variety of techniques used, these data indicate that professors (1) experimented with a diverse portfolio of AL techniques and (2) incorporated all of the techniques over the course of the academic year. The fact that the activities were distributed over all 9 courses indicates that there was no point in the first year in which the courses relied on purely lecture-based instruction with no AL components.

Original Alignment, 2017.

Table 5 presents a curricular map aligning LCE attributes to AL components. Three AL components aligned to real-world relevance, 2 with competency-based, 7 with collaboration, 7 with deliberate practice, and 6 with technology/multimedia. The results of this curricular map suggest that the teaching faculty had successfully incorporated key elements of a learning-centered approach.

Discussion

The process of inventorying AL techniques used in the curriculum has been valuable. This study reflects our effort to demonstrate learning-centered culture, focused on the scholarship of teaching and learning. In the current phase, it appears that there is a promising level of saturation of AL within LG sessions (74%). The frequency and variety of AL components integrated across the 9 courses reflected faculty fluency with a range of techniques and their support of an AL culture.

The process of our inventory, data analysis, and literature review was useful in confirming preferences for sequencing AL lessons. Although AL shifts the role of instructors from givers of information to facilitators of student learning,[8,42] this does not suggest a zero tolerance for didactics. Our interpretation of AL includes a phase prior to the active component (didactics) when the professor presents or reviews concepts and theories.[12] Following cognitive load theory,[27,28] and principles of team-based learning, facilitated, scaffolded, or mediated AL instruction is preferred, as opposed to purely constructivist, discovery learning with no facilitation.

The Taxonomy of AL Techniques was tested; it functioned well as a categorization tool, and demonstrated a degree of internal validity as categories remained stable across interviews. For faculty, the experience of tracking their own teaching methods prompted self-reflection, along with an opportunity to self-assess and reconsider whether one’s own portfolio of activities was sufficiently diverse. The inventory of AL methods helped faculty review their own portfolios to consider any underutilized techniques they might use in LG sessions. Going forward, the faculty development team intends to deepen faculty capacity to improve AL sessions through faculty learning communities and specific training on facilitation skills.

In terms of AL or LCE, there is no unified cookbook[26] approach; the quintessential attributes of AL and LCE continue to be litigated in the literature, but 5 attributes of LCE—at the lesson level—surfaced through review of literature and were explanatory for our current instructional design. They represent key elements that each contributes to a rich learning experience. The results of this study served to help the research team evaluate progress toward curricular goals described in the COM’s strategic plan, as well as articulate educational values through a consensual, participatory process.

Full engagement in the scholarship of teaching regarding developing an AL culture would not have been possible without the full support of the administration and faculty. In 2013, the COM formed an ad hoc subcommittee or community of practice,[43] to help guide the transition toward AL. Department chairs have been instrumental in consistently encouraging faculty to try new techniques. They supported a learning-centered culture whereby faculty and staff could participate in ratifying the Taxonomy through a modified Delphi[44] method. These conditions led to a blossom period of experimentation with 25 AL techniques.

Limitations

This was a pilot study at a single institution. The results may not be generalizable to other institutions. The research design involved narrative faculty interviews, during which faculty fact-checked and self-reported regarding their lesson formats. We avoided recording faculty interviews to reduce the misperception that this study was in some fashion, an evaluative critique. Although semistructured interviews and 2 other data points allowed for triangulation of findings (lesson content loaded on the LMS and course schedule), we acknowledge the bias inherent in faculty participant self-reporting. However, faculty bias was mitigated due to evidence provided by individual faculty during interviews. For example, during interviews, most faculty checked their online lessons, including electronic files of PowerPoint and vodcast presentations, lecture capture videos, or online media such as games or interactive modules. Others consulted procedure notes, handouts, quizzes, or sample discussion questions associated with individual active lessons.

Our study aligned AL techniques to 5 attributes of LCE. In future studies, we could answer this question: Do faculty and students conceive the AL components to be learning-centered? This study did not focus on the ways in which these AL components, when implemented, specifically activated student learning, or the degree to which students took part in them. However, through several prior published studies, we had already demonstrated that AL fosters student engagement, clinical reasoning, collaboration, and self-evaluation. Indeed, our students have been full partners in testing and evaluating most of the various learning techniques listed in the Taxonomy.

Conclusions

The results of this study found that most LG hours in the first year curriculum included an AL component (74%). The components of AL implemented most frequently were discussion and debate, case-based instruction, audience response, formative quizzes, and demonstrations. Faculty used all 25 AL techniques and integrated AL components into all 9 courses; there was no point in the first year in which the courses relied on purely lecture-based instruction with no AL components. These statistics, along with the frequencies provided for each AL component, effectively measure the saturation and breadth of AL in the curriculum.

We encourage other COMs to assess the saturation and breadth of AL in their curriculum and align with the key attributes of LCE within their native institutions. At our institution, conducting this type of curricular inventory helped faculty achieve consensus, set goals, identify practice gaps, and explore ways to improve instruction. This experience has been valuable in terms of identifying specific training needs and transformations required at the instructor and institutional level to achieve a signature, well-balanced LCE approach, with the ultimate goal of preparing competent and knowledgeable physicians of the future.
