<title>Objective</title>
<p>The Jigsaw method is an excellent collaborative learning strategy that actively involves students, improves their problem-solving abilities, and promotes individual accountability. This study investigated the effectiveness of the Jigsaw teaching and learning technique in enhancing medical students&#x2019; knowledge of nutrition, specifically focusing on fat-soluble vitamins and B complex vitamins in medical students.</p>
</sec>
<sec>
<title>Methods</title>
<p>A descriptive, cross-sectional, and prospective study was conducted with 176 Biochemistry students (10 males, 166 females) pursuing a Doctor of Medicine (MD) degree. Participants were conveniently sampled. The Jigsaw activity centered on &#x201C;Nutrition,&#x201D; with subtopics including Vitamin A, Vitamin K, B complex (B1, B2, B6), and Biotin and Niacin.</p>
</sec>
<sec>
<title>Results</title>
<p>The results showed across all four teams, mean scores for assignment, presentation, and expert-group activities were comparable, with total scores showing minimal variation. ANOVA demonstrated significant differences in Expert Group (<italic>F</italic> = 11.07, <italic>p</italic> &#x003C; 0.001) and Assignment scores (<italic>F</italic> = 4.24, <italic>p</italic> = 0.006), while Presentation scores did not differ significantly (<italic>F</italic> = 1.08, <italic>p</italic> = 0.358). Pearson correlation analysis showed strong positive associations between assignment, presentation, and total scores, indicating consistent alignment of performance components across teams.</p>
</sec>
<sec>
<title>Conclusion</title>
<p>The Jigsaw method proved effective in boosting student engagement, comprehension, and collaborative skills in complex Biochemistry topics. The study suggests that well-planned active teaching methods like the Jigsaw model can positively impact student learning and help achieve specific learning outcomes in medical education. Our study was limited to one institution; future multi-center, longitudinal and controlled studies are recommended to validate and expand these findings.</p>

<title>Introduction</title>
<p>Enhancing medical students&#x2019; comprehension through active learning and implementing the Jigsaw method to improve engagement is well documented in educational pedagogy (<xref ref-type="bibr" rid="B1">1</xref>). Moreover, cooperative learning strategies, such as the Jigsaw approach, have been recognized as among the most effective methods for promoting inclusion and fostering collaborative learning environments (<xref ref-type="bibr" rid="B2">2</xref>). Medical education (ME) curriculum is vast and involves multiple subjects. Students pursuing undergraduate ME encounter learning challenges owing to the complexity of the medical subjects. Moreover, medical students are expected to learn extensively about the subjects and apply them in practical and during real-life scenarios like patient treatment and management (<xref ref-type="bibr" rid="B3">3</xref>). Many teaching and learning (TL) methodologies have been gaining attention of ME faculties. Numerous teaching and learning (TL) approaches have drawn the attention of ME faculty members. It has been acknowledged that medical education technologies (METs), such as the traditional classroom, may not be adequate to produce competent medical graduates. Hence advanced METs like as problem-based learning, flipped classrooms, personalized learning classrooms, formative classroom evaluations methods, and others gained significance (<xref ref-type="bibr" rid="B4">4</xref>&#x2013;<xref ref-type="bibr" rid="B7">7</xref>).</p>
<p>Jigsaw is a group based cooperative learning approach that was favored by students increasing their interest in learning (<xref ref-type="bibr" rid="B8">8</xref>). The jigsaw methodology was noted to be suitable for both online and offline TL activities (<xref ref-type="bibr" rid="B9">9</xref>). Jigsaw learning approach was first introduced in the 1970s. This TL methodology involves group learning wherein the students are further categorized into sub-groups. Further, in this approach, the students engage in learning different topics and sub-topics under the guidance of peer groups and experts (<xref ref-type="bibr" rid="B10">10</xref>).</p>
<p>Despite its student friendly approach, the jigsaw methodology was found to have mixed effects on the educational outcomes of the students that included aspects like academic achievement, motivation, self-esteem, and social wellbeing. However, it was demonstrated that the jigsaw approach had positive effects on students&#x2019; social self-esteem (<xref ref-type="bibr" rid="B11">11</xref>). Jigsaw method was applied among nursing students and the results demonstrated that this approach improved student&#x2019;s academic achievement, skills, and attitudes (<xref ref-type="bibr" rid="B12">12</xref>). Conversely, Riant et al. (<xref ref-type="bibr" rid="B2">2</xref>) raise concerns about the conditions under which the Jigsaw method is implemented for low-achieving students. While further research is needed to consider students&#x2019; actual performance instructions, quized tests, these limitations underscore the need for teachers to ensure that the Jigsaw approach is accompanied by guided and structured instructions a factor repeatedly shown to be critical for its success.</p>
<p>Moreover student and teachers&#x2019; perception of jigsaw approach revealed this method was instrumental in improving the student&#x2019;s communication skills and helped them overcome shyness. Teachers also reported that this method enhanced their teaching effectiveness (<xref ref-type="bibr" rid="B13">13</xref>).</p>
<p>Considering the existing literature, wherein jigsaw appeared to be a favorable TL method to accomplish the student learning outcomes (SLO&#x2019;s), we implemented it in the undergraduate medical education at the College of Medical and Health sciences (COMHS), National University of Science and Technology, Sohar, Oman. The topic on Vitamins was chosen because it makes them interesting for collaborative and student-centered learning. The topic also connects metabolism, enzymology, and clinical relevance, providing a strong model for applying the Jigsaw technique. Based on this rationale, our study aimed to evaluate the effectiveness of the Jigsaw method in enhancing knowledge acquisition, improving student engagement, and exploring its integration into routine medical education as an active teaching-learning strategy.</p>

<title>The jigsaw model implemented in this study</title>
<p>The educational philosophy underlying this strategy is a cooperative learning approach in which students actively engage in structured learning activities, enhance comprehension through peer interaction, and develop collaborative skills by working together in groups. This approach was invented by Elliot Aronson and allows each group member to focus on a single topic or specific learning outcome. The jigsaw technique follows a predetermined, sequential, linear process of student engagement, comprehension and collaboration to accomplish learning outcomes. The original Jigsaw model was used as designed, however, the implementation was contextualized to align with our curriculum structure and class size (<xref ref-type="bibr" rid="B14">14</xref>&#x2013;<xref ref-type="bibr" rid="B16">16</xref>).</p>
<p>An orientation program on jigsaw methodology was provided to the study participants before the initiation of the study. The college follows an outcome-based education framework that incorporates active learning strategies such as Problem-Based Learning (PBL), Case-Based Learning (CBL), and Team-Based Learning (TBL) within the curriculum. Students had prior exposure to these approaches; however, the Jigsaw methodology was newly introduced to this cohort. This technique thus represented an innovative extension of the existing strategies, allowing students to build knowledge together and experience a more collaborative, peer-led form of active engagement.</p>
<p>The selected topic for Jigsaw activity was Vitamins&#x2014;Fat soluble and B complex. The sub-topics assigned were vitamin A (VA), vitamin K (VK), B complex- B1, B2, B6 (VB), and vitamins biotin and niacin (VBiNi). The rationale for selecting this topic was that each vitamin follows a specific sequence, dietary sources, active coenzyme forms, recommended daily allowances (RDA), clinical manifestations, and deficiency disorders, which makes it easier for students to understand, master, and share with peers. This structure makes vitamins an ideal choice for self-directed, collaborative, and student-centered learning. Furthermore, the topic bridges concepts of metabolism, enzymology, and clinical relevance, making it an effective model for integrative Biochemistry learning through the Jigsaw technique.</p>

<title>Students&#x2019; division</title>
<p>A total of 176 students were divided into 4 groups A, B, C, and D, each comprised 40&#x2013;44 students. The students were routinely divided into four practical groups (A&#x2013;D) of about 41&#x2013;44 students in each group. These groups rotate simultaneously across Anatomy, Physiology, and Biochemistry practical sessions. This existing organizational structure provided manageable group sizes, enabling active participation, close faculty facilitation, and effective peer interaction. Thus, the 4-day schedule reflected a practical adaptation of the regular timetable slots designated to Biochemistry practical or tutorial using our existing faculty without additional workload (<xref ref-type="fig" rid="F1">Figure 1</xref>).</p>

<alt-text content-type="machine-generated">Diagram illustrating the Jigsaw Learning Model for 176 students, divided into four groups of 44 each: A, B, C, and D. In Step 1, students meet in Home Groups for pre-class study, with each group assigned a vitamin. In Step 2, students engage in peer learning in Jigsaw Groups, mixing members from each Home Group. In Step 3, students regroup into Expert Groups where they integrate knowledge from peers, returning to their Home Groups as experts. Each step highlights specific groups and their members.</alt-text>
</graphic>
</fig>
<p><italic>Step 1:</italic> Within each day, students were further subdivided into four home groups (VA, VK, VB, VBiNi) of approximately 10&#x2013;12 members each. Individual handwritten assignments were submitted by each participant. These were narrative in format, addressing multiple levels of Bloom&#x2019;s taxonomy. The questions were directly aligned with the session learning outcomes (SLOs). Student engagement was reflected in this Step (<xref ref-type="fig" rid="F1">Figure 1</xref>).</p>
<p><italic>Step 2:</italic> Three students from the different home groups VA, VK, VB, VBiNi came together to form the &#x201C;jigsaw groups.&#x201D; Thus, 4 jigsaw groups named 1&#x2013;4 were formed. The students in the jigsaw groups included members from different home groups with different topics. The jigsaw group works together with each other discussing all the aspects of the given sub-topics, for an hour. Peer teaching among the groups enables the participants to learn other vitamins. During the process facilitators were present for each group (4 in number), who assessed the peer teaching through a rubric which was content validated and ensured internal consistency across the four groups. Cronbach&#x2019;s alpha was calculated for the rubric items (&#x03B1; = 0.78), demonstrating satisfactory reliability for use in this context. This step reflected students&#x2019; level of comprehension.</p>
<p><italic>Step 3:</italic> The Jigsaw group members return back to their respective home groups as an &#x201C;expert group.&#x201D; Each Expert group will have members who learnt all other vitamins from their peers and do a group activity of comprehending knowledge and submitting a collective assignment for all vitamin topics. Student collaborative skills were reflected during this Step.</p>
<p>The initial individual assignment and the final collective expert-group assignment were structured activities aligned with the session learning outcomes (SLOs) and mapped to Bloom&#x2019;s taxonomy. Model answers were used for both assessments to ensure uniformity, objectivity, and consistency in scoring across all groups.</p>
<p>Following the procedure, the students were evaluated based on the COMHS rubric for jigsaw presentation session as shown in <xref ref-type="table" rid="T2">Table 2</xref>.</p>

<title>Educational impact of the jigsaw method</title>
<p>Cooperative learning is widely recognized as an effective educational strategy that enhances student engagement, comprehension, and overall academic performance. The Jigsaw method, a form of cooperative learning, actively involves students in the TL process, where learners not only take responsibility for their learning but also contribute to their peers&#x2019; understanding (<xref ref-type="bibr" rid="B14">14</xref>&#x2013;<xref ref-type="bibr" rid="B17">17</xref>). The SPICES model (student-centered, problem-based learning, integrated teaching, community-based, electives, and systematic) strongly advocates for student-centered learning approaches (<xref ref-type="bibr" rid="B18">18</xref>). Research suggests that active engagement strategies improve long-term knowledge retention (<xref ref-type="bibr" rid="B19">19</xref>, <xref ref-type="bibr" rid="B20">20</xref>) and enhance academic performance when incorporated into traditional passive learning methods (<xref ref-type="bibr" rid="B21">21</xref>, <xref ref-type="bibr" rid="B22">22</xref>). The Jigsaw technique not only fosters comprehension but also promotes cooperation, effective communication, and listening skills among students (<xref ref-type="bibr" rid="B23">23</xref>&#x2013;<xref ref-type="bibr" rid="B26">26</xref>). One-way ANOVA results and <italic>post hoc</italic> interpretation showed significant differences between groups for Expert Group scores (<italic>F</italic> = 11.07, <italic>p</italic> &#x003C; 0.001) and Assignment scores (<italic>F</italic> = 4.24, <italic>p</italic> = 0.006). Presentation scores did not differ significantly among the four groups (<italic>F</italic> = 1.08, <italic>p</italic> = 0.358). These findings suggest that some teams performed significantly better than others in expert group discussions and assignments, likely due to variations in student engagement, participation levels, and group dynamics. These results align with Puppalwar et al. (<xref ref-type="bibr" rid="B27">27</xref>), who found that cooperative learning significantly improved student scores compared to traditional methods. Similarly, Nusrath et al. (<xref ref-type="bibr" rid="B28">28</xref>) suggested that the Jigsaw method enhances academic engagement and comprehension in Biochemistry education.</p>
<p>The correlation analysis highlights key relationships among performance categories across different Groups. In Group A, strong positive correlations were observed between total scores and both assignments (<italic>r</italic> = 0.757, <italic>p</italic> &#x003C; 0.01) and presentations (<italic>r</italic> = 0.715, <italic>p</italic> &#x003C; 0.01). However, a weak correlation was noted between assignment and presentation scores (<italic>r</italic> = 0.333, <italic>p</italic> &#x003C; 0.05), suggesting that performance in one category may not necessarily predict performance in another. This is consistent with findings from Goolsarran et al. (<xref ref-type="bibr" rid="B29">29</xref>) who reported that structured cooperative learning interventions improved overall student scores but had varying impacts on individual assessment components. A similar trend was seen in Group B, where total scores had significant positive correlations with assignments (<italic>r</italic> = 0.841, <italic>p</italic> &#x003C; 0.01) and presentations (<italic>r</italic> = 0.792, <italic>p</italic> &#x003C; 0.01), reinforcing prior studies that emphasize the role of teamwork in academic success.</p>
<p>For Group C, significant positive correlations were also found between total scores and assignments (<italic>r</italic> = 0.650, <italic>p</italic> &#x003C; 0.01) as well as presentations (<italic>r</italic> = 0.820, <italic>p</italic> &#x003C; 0.01). This aligns with research by Bogam et al. (<xref ref-type="bibr" rid="B30">30</xref>), who found that cooperative learning methods helped students retain subject knowledge effectively, particularly in complex topics like Type 2 diabetes mellitus. In contrast, Group D exhibited a different pattern, with total scores significantly correlating with assignments (<italic>r</italic> = 0.646, <italic>p</italic> &#x003C; 0.01) and presentations (<italic>r</italic> = 0.711, <italic>p</italic> &#x003C; 0.01), but negative and non-significant, correlations between assignments and expert group scores (<italic>r</italic> = &#x2212;0.301) and between total scores and expert group scores (<italic>r</italic> = &#x2212;0.026). This suggests that although teamwork and engagement play a crucial role, the effectiveness of expert group discussions may depend on individual group dynamics and instructional structure, similar to observations by Dollard et al. (<xref ref-type="bibr" rid="B31">31</xref>) on classroom cooperation.</p>

<sec id="S4.SS2">
<title>Student engagement and collaborative skills</title>
<p>When examining total score correlations among teams, Group A and Group C exhibited a moderate yet significant positive correlation (<italic>r</italic> = 0.467, <italic>p</italic> &#x003C; 0.01), suggesting some consistency in performance trends. However, Group B&#x2019;s total score had a negative, though non-significant, correlation with the scores of Groups A, C, and D, implying a different performance pattern compared to the other groups. This variation supports the findings of Goolsarran et al. (<xref ref-type="bibr" rid="B29">29</xref>) who noted that while cooperative learning generally improves academic outcomes, individual team performance may be influenced by multiple external factors such as peer collaboration, motivation, and prior knowledge.</p>
<p>Studies have shown that cooperative learning strategies such as the Jigsaw method improve student comprehension, problem-solving abilities, and engagement. Research in medical and pharmaceutical education has demonstrated that the Jigsaw method enhances abstract thinking, clinical reasoning, and long-term patient care skills (<xref ref-type="bibr" rid="B32">32</xref>&#x2013;<xref ref-type="bibr" rid="B36">36</xref>). Puppalwar et al. reported that students using cooperative learning performed better than those in traditional lecture-based learning and found Biochemistry more engaging through this approach (<xref ref-type="bibr" rid="B27">27</xref>). Similarly, Nusrath et al. recommended implementing the Jigsaw method for teaching clinical Biochemistry topics (<xref ref-type="bibr" rid="B28">28</xref>). Goolsarran et al. applied this method to medical postgraduate education in patient safety and found it to be both feasible and effective (<xref ref-type="bibr" rid="B29">29</xref>). Likewise, Bogam et al. used the Jigsaw method to teach Type 2 diabetes mellitus to first-year medical students and observed significant knowledge gains, recommending a shift from traditional lectures to cooperative learning (<xref ref-type="bibr" rid="B30">30</xref>).</p>
<p>The cooperative learning model, as observed by Dollard et al. (<xref ref-type="bibr" rid="B31">31</xref>) eliminates classroom competition and fosters collaboration. However, despite its numerous benefits, implementing the Jigsaw method in medical education presents logistical challenges, including time constraints and structural limitations (<xref ref-type="bibr" rid="B13">13</xref>, <xref ref-type="bibr" rid="B36">36</xref>&#x2013;<xref ref-type="bibr" rid="B39">39</xref>). More research is needed to explore its feasibility in diverse educational settings, particularly in Biochemistry education in regions like Oman, where studies remain limited (<xref ref-type="bibr" rid="B31">31</xref>&#x2013;<xref ref-type="bibr" rid="B34">34</xref>). Our study underscores the value of cooperative learning strategies in enhancing student performance. While the Jigsaw method has proven to be effective, its implementation requires careful planning to overcome challenges associated with medical education curricula.</p>

<title>Conclusion</title>
<p>The results of this study indicate that cooperative learning through the Jigsaw method enhances student engagement and comprehension of Biochemistry topics. This approach fosters teamwork, communication skills, and active participation, encouraging students to take responsibility for their own learning while supporting their peers.</p>
<p>Well-structured teaching&#x2013;learning strategies, such as the Jigsaw model, when implemented with appropriate planning and resource alignment, can positively impact student performance and knowledge retention. Integrating collaborative learning into routine teaching enables educators to achieve session learning outcomes more effectively and supports outcome-based medical education.</p>
<p>Future research should explore strategies to further optimize Jigsaw implementation, to facilitate its broader adoption within Biochemistry, medical, and allied health care curricula.</p>
