Employing students' evaluations and tutors' perceptions to evaluate a faculty development program on problem-based learning at the Faculty of Medicine, King Abdulaziz University.

BACKGROUND: Faculty development programs are crucial for promoting continuous learning, enhancing teaching effectiveness, and encouraging professional growth among medical educators. Problem-based learning was introduced as a teaching strategy in our Faculty of Medicine in 2007. Thereafter, several rounds of a faculty development program were conducted to help teachers recognize their role as facilitators and assess areas for improvement. METHODS: We conducted a mixed-methods study with a sample of 284 third-year medical students answering a questionnaire and 21 faculty members participating in focus groups. A validated 13-item questionnaire was used to investigate the students' evaluation of their tutors' performance in problem-based learning. Three sessions were then conducted with faculty members involved in problem-based learning to gain in-depth insights into their experiences and perspectives. RESULTS: The mean performance ranking for tutors awarded by the students was above halfway. There was a significant positive correlation between tutors' performance ranking and all five of the learning approaches examined herein: constructive/active learning, self-directed learning, contextual learning, collaborative learning, and intra-personal behavior (p < 0.05). The data from the focus groups were analyzed under five broad themes: tutors' insights into their strengths and weaknesses, challenges in conducting problem-based learning, tutors' ways of preparing for problem-based learning, feedback, and suggestions for improving problem-based learning workshops. CONCLUSIONS: This study recommends improvements and future directions for advanced program evaluation. Faculty development programs can be tailored to effectively address students and faculty members' goals and needs, which can benefit the teaching and learning process and foster a culture of continuous improvement and professional growth.

Core Competencies of an Anti-racist Physician: Elective Course for Undergraduate Medical Students.

Introduction: Medical schools seeking to correct and reform curricula towards anti-racist perspectives need to address anti-Black forms of racism specifically and teach students critical upstander skills to interrupt manifestations of racism. We developed a course to teach preclinical medical students basic anti-racism competencies including recognition and awareness of anti-Black racism in medicine and upstander skills to advocate for patients and colleagues. Methods: In 2021 and 2022, we designed, implemented, and evaluated an elective course for second-year medical students (N = 149) to introduce competencies of anti-racism focusing on upstander skills for addressing anti-Blackness. We designed three patient cases and one student-centered case to illustrate manifestations of anti-Black racism in medicine and used these cases to stimulate small-group discussions and guide students toward recognizing and understanding ways of responding to racism. We designed pre- and postassessments to evaluate the effectiveness of the course and utilized anonymous feedback surveys. Results: Participants showed significant improvement in pre- to postassessment scores in both years of the course. The anonymous feedback survey showed that 97% of students rated the course at least somewhat effective, and the qualitative responses revealed five core themes: course timing, case complexity, learner differentiation, direct instruction, and access to resources. Discussion: This course reinforces upstander competencies necessary for advancing anti-racism in medicine. It addresses a gap in medical education by reckoning with the entrenched nature of anti-Black racism in the culture of medicine and seeks to empower undergraduate medical students to advocate for Black-identifying patients and colleagues.

Online-to-offline combined with problem-based learning is an effective teaching modality in the standardized residency training of nephrology.

BACKGROUND: The online-to-offline (O2O) teaching method is recognized as a new educational model that integrates network learning into offline classroom education, while problem-based learning (PBL) is a teaching modality that guides students to apply acquired theoretical knowledge to solve practical problems. However, implementing O2O combined with PBL has not been extensively explored in nephrology residency training. This study aims to explore the efficacy of O2O combined with PBL in the standardized residency training of nephrology by comparing it with the traditional lecture-based teaching (LBT). METHODS: Sixty residency trainees who participated in the standardized training of internal medicine in the nephrology department of the Second Affiliated Hospital of Zhejiang University School of Medicine were equally allocated into O2O combined with PBL (O2O/PBL) or the LBT group demographically matched. Examinations of theory, practice skills, clinical thinking and teaching satisfaction surveys were utilized to assess the teaching effects of the two groups. RESULTS: Participants from the O2O/PBL group outperformed those from the LBT group in the examination of theory (81.233 ± 9.156 vs. 75.800 ± 7.009, mean ± SEM), practice skills (104.433 ± 3.569 vs.100.316 ± 4.628, mean ± SEM) and clinical thinking (88.933 ± 4.473 vs. 86.667 ± 3.844, mean ± SEM). There was no significant difference in the teaching satisfaction between the two groups. CONCLUSION: The current study shows the positive impact of O2O combined with PBL approach on standardized residency training in nephrology without reducing teaching satisfaction.

Application of Emerging Teaching Models in Dental Education: A Systematic Review and Meta-Analysis.

INTRODUCTION AND AIMS: As an experimental teaching method, emerging learning methods including problem-based learning (PBL), case-based learning, team-based learning and flipped classroom (FC) have been widely applied in dental education. This study aims to evaluate the effect of these teaching methods on dental education performance compared to traditional lecture-based learning (LBL). METHODS: The search was carried out in April 2024 in PubMed, EMBASE, Web of Science, and Cochrane Library. All randomized controlled trials were included and the methodological quality assessment was based on the guidelines described in the Cochrane Handbook for Systematic Reviews, followed by a meta-analysis using Stata 14.0 software. Using standard mean deviation (SMD) and 95% confidence interval (95% CI) to determine the effectiveness of emerging teaching methods and LBL in all dental disciplines. Meta-regression was used to analyse sources of heterogeneity. Sensitivity analysis was performed to determine the stability, and Begg's analysis was used to determine whether there is publication bias. RESULTS: A total of 29 randomized controlled trials including 3502 students were included. The results indicate that emerging educational methods have a significantly positive effect on achieving higher scores (SMD = 0.48, 95% CI = 0.34-0.62, P < .001), whether it was theoretical scores (SMD = 0.52, 95% CI = 0.32-0.72, P < .001) or skill scores (SMD = 0.45, 95% CI = 0.15-0.76, P < .001). Compared to LBL, PBL (SMD = 0.33, 95% CI = 0.01-0.65, P = .045) and FC (SMD = 0.50, 95% CI = 0.31-0.69, P < .001) can both significantly improve students' academic performance. CONCLUSION: Compared to LBL, emerging educational methods (PBL, case-based learning, and FC) have significantly improved the learning effectiveness of dental students. These emerging educational methods can be advocated and popularized as routine teaching methods. CLINICAL RELEVANCE: This study is the first meta-analysis of the effects of emerging teaching methods in dental education which shows great impact of emerging teaching methods on students' development.

Pathology as a Basic Medical Subject: Its Relevance and Application During Clinical Practice in Jordanian MD Programs, Interns' and Residents' Perspectives.

Aim: Medical literature revealed that there is a lack of information about the opinions of medical interns and residents about curricula provided to them during their undergraduate programs, either in a group of detached subjects or an incorporated and efficacious topic (ie, pathology). Purpose: To assess and compare the interns' and residents' perspectives towards Pathology as a subject. To recognize their opinions toward the relevance and application of Pathology while practicing clinically. Methods: This study was a cross-sectional online, self-administered questionnaire targeting interns and residents. The questionnaire consisted of 30 questions, enquiring about the demographic data, subject strength, teaching duration, interest in the subject, and usefulness of Pathology as a subject in clinical practice. Results: Overall, 103 participants completed the survey. The female and male percentage was 59.2% and 40.8% respectively. 86.4% of participants were interns, while 13.6% were residents. 87% of participants agreed that applying pathology during clinical practice is a skill that should be strengthened in the early stages of preclinical education of Medicine. A modest percentage believed that a practitioner could efficiently treat the majority of patients with no need to know the specifics of the pathological mechanisms involved. Most of the participants believed that pathology courses helped them in making a differential diagnosis, analysis of normal and pathological constituents, and dissection and identification of structures. Conclusion: This study highlights the positive perceptions of Jordanian interns and residents toward pathology courses. It also demonstrates that participants prefer an active and dynamic educational model with an emphasis on better integration of pathology courses and clinical experiences that fit their needs in clinical practice. Thus, we recommend future studies to compare the competencies of interns and residents enrolled in the courses with integrated medical curricula, of pathology versus those who studied the conventional medical curricula of pathology, as well as to evaluate their perceptions of medical education.

Countering vaccine misinformation: Designing a learning resource for healthcare workers in eight countries.

In response to the pervasive challenges posed by online health misinformation, our objective was to develop a training program aimed at enhancing the skills and confidence of healthcare workers in recognizing and effectively responding to misinformation, with a particular focus on vaccinations. This article discusses the design of a training program aimed at equipping healthcare workers with the skills to combat health misinformation, offering theoretical foundations for integrating evidence-based strategies into problem-based learning to help learners retain and apply information, and also shares examples and insights gained from its application across diverse learner groups. The training curriculum integrates evidence-based misinformation intervention strategies, learner engagement strategies and draws from authentic scenarios across diverse cultural contexts. The trainings were administered from January through July 2023 to 287 participants across eight countries (Cameroon, Guyana, India, Kenya, Mozambique, Nigeria, Philippines, and the United States) in English, French, Spanish, and Portuguese. Throughout the implementation of the training, a key emphasis was placed on a learner-driven approach that fostered real-world application. Participants engaged in role-playing exercises and problem-solving sessions, enabling them to practice their newfound skills in a controlled setting. Our findings contribute to the literature of participatory, problem-based learning for healthcare professionals and vaccine communication and misinformation response, and can serve as a resource for practitioners implementing similar trainings.

Implementation of problem-based learning modules in an introduction to public health course.

Introduction: With traditional lecture-based learning methods often criticized for their limited ability to foster critical thinking and cognitive engagement, problem-based learning (PBL) has emerged as a promising alternative. This research investigates the impact of PBL on student learning outcomes, specifically focusing on the development of higher-order thinking skills, communication, growth mindset, and metacognitive abilities. Methods: PBL was implemented in an undergraduate public health course at a private university in the southeast US. The study was conducted in the Spring of 2022 using a convergent mixed-methods approach. Quantitative data were derived from university-wide Quality Enhancement Plan surveys and a course-specific PBL survey, which were analyzed using Repeated Measures ANOVA to assess changes in student perceptions over time. Additionally, qualitative data from open-ended survey questions were analyzed through thematic analysis, providing deeper insights into the students' experiences and perceptions of PBL. Results: Results indicated significant improvements in student communication skills, growth mindset, and metacognitive abilities across the semester. The thematic analysis of qualitative responses corroborated these findings, revealing enhanced team collaboration, active engagement in problem-solving, and increased comfort with complex real-world issues. Discussion: The findings contribute to the growing body of evidence supporting PBL and offer practical insights for implementing PBL in public health education. The study also highlights the need for institutional support in adopting innovative teaching methods like PBL, emphasizing faculty development, resource allocation, and curriculum design.

Problem-Based Learning for Interprofessional Education: A Review of the Concept and Its Application in a Geriatric Team.

The global population is aging, with those aged 65 years or over increasing in number and accounting for a growing share of the population. There are increasing demands for geriatric care which makes the development and delivery of effective geriatric team training a priority. Training in geriatrics is complex because of the multiplicity of medical, psychosocial, and functional issues in elderly individuals which need to be addressed by a multidisciplinary approach using interprofessional education (IPE). Problem-based learning, a student-centered educational model that brings several natural strengths to IPE, is a unique curriculum replacing the traditional lecture-based learning model. This model enhances physician competency after graduation, mainly in psychosocial and teamwork issues that are fundamentally essential for geriatrics. IPE has been shown to have a substantial positive impact on team collaboration, individual development, and healthcare improvement. In this paper, we summarize the current findings from recent studies on training professionals from different healthcare disciplines to deliver care for the elderly in collaborative practice. We also discuss if an interprofessional problem-based geriatric team program in geriatrics is a promising solution to enhance professional collaboration and quality of patient care.

Comparing students' performance in self-directed and directed self-learning in College of Medicine, University of Bisha.

Background: Student-centered learning strategy increases the likelihood of graduation of competent, self-dependent, and problem-solving physicians. The University of Bisha, College of Medicine (UBCOM) adopted self-directed learning (SDL) represented by problem-based learning (PBL), and directed self-learning (DSL) represented by team-based learning (TBL). Aim: To compare the students' performance in SDL and DSL among UBCOM students. Methodology: A total of 502 multiple choice questions (MCQs) from the mid-course and final exams were collected by the relevant subject experts from nine courses during the period from September 2020 till June 2023 that adopted PBL and TBL; 247 MCQs related to PBL and 255 related to TBL. Psychometric analysis was used to determine difficult, easy, and optimum questions (≤25%, ≥90%, and 26-89%, respectively). Point biserial as <0.19, 0.20-0.29, 0.30-0.39, and >0.40 which indicate poor, marginal, good, and excellent point biserial, respectively. Finally, the number of functional distractors was attempted by >5% of the candidates. Results: No significant differences were noted for the students' performance in MCQs related to PBL (representing self-directed, small group learning tool), and TBL (representing directed-self, large group learning tool) regarding difficulty index (DI), point biserial, and distractors functionality. Conclusion: It has been observed that there is no difference in students' performance whether PBL or TBL is used for learning Basic Medical Science courses. Small group learning such as PBL needs more resources in comparison to large group learning as in TBL, therefore any institute can decide on the adopted learning strategy depending on its resources and the number of students.

Problem-Based Learning - An Overview.

The main objective of Problem-Based Learning (PBL) is to develop problem-solving skills, collaborative learning skills, self-directed learning skills, communication skills, deeper learning skills, lifelong learning skills, and better retention in the students to equip them better in their professional careers. Unlike the traditional curriculum which is mainly based on didactic lectures, PBL is based on a group of students working on a problem and solving it. PBL is a promising teaching and learning tool that can be adopted in all fields, especially in Medical and Dental curricula.

A Student-Driven Approach to Course Revitalization.

A first-year foundational science course grew beyond its scope. Revitalization of the course was driven by second and third-year medical students, who created new learning objectives and edited cases that were well-received by course facilitators and students. The students' role in the course revitalization is a novel approach.

Problem-Based Learning in Medical Education: A Global Research Landscape of the Last Ten Years (2013-2022).

Background: Problem-based learning (PBL) constructs a curriculum that merges theory and practice by employing clinical scenarios or real-world problems. Originally designed for the pre-clinical phase of undergraduate medicine, PBL has since been integrated into diverse aspects of medical education. Therefore, this study aims to map the global scientific landscape related to PBL in medical education in the last ten years. Methods: We combined bibliometrics and network analysis to analyze the metadata of related research articles published between 2013 and 2022 and indexed in the Web of Science Core Collection.

The USA and China are the most publishing countries, while the Netherlands and Canada are the most collaborative. The Maastricht University holds the position of most publishing and collaborative research organization. The University of California ranks second in publications, while the University of Toronto is the second most central research organization. Conclusions: Our study provides an overview of the last ten years of publications related to PBL and medical education, and we hope it can be of interest to educators, researchers, and students involved with this subject. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-024-02003-1.

Using unfolding case studies to develop critical thinking for Graduate Entry Nursing students: an educational design research study.

BACKGROUND: Graduate Entry Nursing (GEN) programmes have been introduced as another entry point to nurse registration. In the development of a new GEN programme, a problem-based approach to learning was used to develop critical thinking and clinical reasoning skills of motivated and academically capable students. OBJECTIVE: To explore and evaluate the design and delivery of course material delivered to GEN students embedded in authentic learning pedagogy from the perspectives of both GEN students and academic staff using an unfolding case study approach. METHODS: An educational design research approach was used to explore the learning experiences of GEN students using an unfolding case study approach situated in experiential pedagogy and the teaching experiences of the academics who designed it. Data were collected through semi-structured interviews with students once they had finished the course and weekly reflective diary recordings by academic staff throughout implementation. Thematic analysis was used to analyse the data. FINDINGS: Student reflections highlighted that this cohort had insight into how they learned and were comfortable voicing their needs to academic staff. While the unfolding case studies were not liked by all participants, for some it offered a unique learning opportunity; particularly when scaffolded with podcasts, simulation labs, tutorials and clinical placements. Staff reflections primarily aligned with student experiences. CONCLUSION: The gaps highlighted in the delivery of the course suggest that a blended pedagogical approach to graduate entry nurse education is required. Specifically, GEN students are aware of the learning needs and are happy to express these to academic staff, thus suggesting that engaging with a co-design curriculum approach will benefit future cohorts.

A problem-based learning experience in a radiology rotation for sixth-year medical students.

OBJECTIVE: To analyse a problem-based learning experience (PBL) in the sixth year of medicine, within a course organised in successive rotations of 12 school days for 7 annual groups. MATERIAL AND METHODS: Each group was divided into subgroups of 6-8 students. Each subgroup was assigned two cases with radiographic images that they had to prepare and present in a joint session in which the students discussed each case and the teacher acted as moderator, without providing solutions. Finally, they had 15 days to complete the debate in an online forum and prepare a written report on each case. RESULTS: During 6 consecutive years, 1001 students participated, whose annual grades ranged between 7.7 ±â€¯1.6 and 9.0 ±â€¯0.7 (mean ±â€¯standard deviation). No correlation was found between the degree of difficulty assigned to the cases and the mean score obtained by each group (R2 = 0.0115). Sixty-six point two percent completed a questionnaire rating various aspects of this experience above 4 out of 5 points and providing overall scores above 8.3 out of 10 points in the different years. The students found this experience appropriate to the objectives of the subject and useful for their educational needs. CONCLUSIONS: PBL allows students to acquire skills of understanding, reasoning and deepening in radiological diagnosis. This study demonstrates that an experience based on PBL can be included in a radiology course organised in a traditional way, allowing students to be graded regardless of the difficulty of the cases.

Evaluating the impact of distance learning on gender-affirming healthcare competence: knowledge acquisition and satisfaction among healthcare professionals in Italy.

Background: Transgender and gender diverse (TGD) individuals face significant healthcare barriers, with one of the most critical being the inadequate knowledge and skills of healthcare professionals (HCPs) in TGD health. To address this issue, we undertook a project to develop a distance learning course for all healthcare professions, encompassing a comprehensive range of topics related to TGD health issues. Objectives: This study aimed to evaluate the impact of a course on gender-affirming healthcare competence, with a focus on knowledge acquisition and satisfaction levels. The hypothesis was that participating in the course would enhance the participants' knowledge on the covered topics. Methods: A distance learning course, designed for all Continuing Medical Education professions, was conducted between March and September 2023. The course was structured according to the Problem-Based Learning methodology. We implemented a pre-test vs. post-test study design to evaluate the enhancement of knowledge, based on a set of Multiple Choice Questions (MCQs), and investigated users' satisfaction through the administration of a semi-structured questionnaire. We examined the pre- and post-course proportions of correct responses to questions, along with the mean score difference, categorized by learners' sex, age, and geographical area. Eventually, a Satisfaction Training Index was created. Results: The maximum capacity was reached, with 29,998 out of 30,000 available spots filled. Of those enrolled, 18,282 HCPs successfully completed the training. Post-test results revealed an increase in correct answers across all MCQs, with overall mean score rising from 48.8 to 68.0 (p < 0.001). Stratified analysis indicated improvements across all participant categories. A higher average increase among female (19.87) compared to male enrollees (17.06) was detected (p < 0.001). Both "over 55" and "46-55" age groups showed the greatest score increases compared to "35-46" and "under 35" groups, despite no significant differences in pre-test scores. Course satisfaction was high, averaging 4.38 out of 5. Top-rated aspects included "learning new concepts" (4.49), "accessibility" (4.46), and "platform functionality" (4.46). Conclusion: Our research hypothesis was confirmed by the significant increase in knowledge going from pre-test to post-test and by the high level of user satisfaction. The obtained results serve as a foundation for planning additional professional education in TGD health.

The effectiveness of problem-based learning and case-based learning teaching methods in clinical practical teaching in TACE treatment for hepatocellular carcinoma in China: a bayesian network meta-analysis.

PURPOSE: To investigate the effectiveness of problem-based learning (PBL) and case-based learning (CBL) teaching methods in clinical practical teaching in transarterial chemoembolization (TACE) treatment in China. MATERIALS AND METHODS: A comprehensive search of PubMed, the Chinese National Knowledge Infrastructure (CNKI) database, the Weipu database and the Wanfang database up to June 2023 was performed to collect studies that evaluate the effectiveness of problem-based learning and case-based learning teaching methods in clinical practical teaching in TACE treatment in China. Statistical analysis was performed by R software (4.2.1) calling JAGS software (4.3.1) in a Bayesian framework using the Markov chain-Monte Carlo method for direct and indirect comparisons. The R packages "gemtc", "rjags", "openxlsx", and "ggplot2" were used for statistical analysis and data output. RESULTS: Finally, 7 studies (five RCTs and two observational studies) were included in the meta-analysis. The combination of PBL and CBL showed more effectiveness in clinical thinking capacity, clinical practice capacity, knowledge understanding degree, literature reading ability, method satisfaction degree, learning efficiency, learning interest, practical skills examination scores and theoretical knowledge examination scores. CONCLUSIONS: Network meta-analysis revealed that the application of PBL combined with the CBL teaching mode in the teaching of liver cancer intervention therapy significantly improves the teaching effect and significantly improves the theoretical and surgical operations, meeting the requirements of clinical education.

The Application of Problem-Based Learning Combined With Case-Based Learning in EEG Teaching.

OBJECTIVE: The aim of this study is to explore the application effectiveness and value of combining problem-based learning (PBL) and case-based learning (CBL) in clinical electroencephalography (EEG) education. METHODS: A total of 104 standardized training for residents and refresher physicians from the Neurology Department of the First Affiliated Hospital of Chongqing Medical University, Neurology Department of Chongqing Yubei Hospital, and Neurology Department of Banan Hospital of Chongqing Medical University were enrolled. According to randomization principles, 52 participants were assigned into the PBL-CBL combination group and 52 subjects were assigned into the control group. We used statistical methods to compare the differences between the 2 groups in basic theory, case analysis, practical assessment scores, and teaching satisfaction. RESULTS: In terms of basic theory, case analysis, practical assessment scores, and teaching satisfaction, there were significant differences between the 2 groups, and the PBL-CBL combination group was superior to the control group (P < .05). CONCLUSION: In clinical EEG education, the teaching model of combining PBL and CBL has certain application effects and value.

Imparting child nutritional assessment skills among medical students using hybrid problem-based learning approach in a community setting.

Background: Malnutrition affects up to a third of children in India, with severe and acute malnutrition prevalent among under five children. Nutritional assessment skills for detecting malnutrition in children in primary care settings are vital. Hybrid problem-based learning (HPBL) is an innovative, collaborative, and adaptable instructional learning strategy that can be used to teach medical students clinical skills in a community setting. Methods: A two-month quasi-experimental study was undertaken in a rural setting with third-year medical students. Faculty members were sensitized and subject experts developed a training module addressing the knowledge, attitude, communication, and practice domains. The students underwent a 3-week training module where pre-testing, case presentation, and group formation in first week, an anchoring lecture, tutorial and self-directed learning and role-play by students in subsequent week, and in last week, case discussion, post-testing, and feedback rounds were done. Results: In all domains, knowledge (3.8, 0.01), practice (4.3, 0.01), attitude and communication (3.7, 0.01), and proportional satisfactory responses, the HPBL approach resulted in a significant improvement in nutritional assessment competency. Teachers preferred the practical and engaging character of the approach, stating that doubts and questions were better addressed and that they would use it to teach similar topics. Conclusion: HPBL is an excellent teaching method for clinical skills, like nutritional assessment in simulated/field settings. The novel teaching-learning approach was well received by students and faculty members. Learning outcomes and satisfaction rates enhanced in students and faculty were encouraged to apply the approach to other topics.

From Slow Shifts to Fast Flips: Unraveling problem-based learning group function dynamics.

PURPOSE: Problem-Based Learning (PBL) relies on self-directed learning in small groups in the presence of a tutor. While the effectiveness of PBL is often attributed to the dynamics of group function, change in group function over time and factors influencing group function development are less understood. This study aims to explore the development of PBL group function over time to better understand the factors that give rise to high-functioning groups. METHOD: We examined time-function graphs of group function and conducted semi-structured focus group discussions in 2023 with medical students enrolled in a PBL curriculum. Students reflected on their experiences in four different PBL groups, creating time-function graphs to characterize development of group function over 8-12-week periods. We analyzed graphs and transcripts in a staged approach using qualitative description and direct content analysis, sensitized by two frameworks: Tuckman's Stages of Group Development and the Dimensions of PBL Group Function. RESULTS: Three archetypes of PBL group function development were identified: Slow Shifters, Fast Flippers, and Coasters. (1) Slow Shifters were characterized by a complex and extended pattern of growth consistent with Tuckman's model, typically occurring amongst inexperienced groups, or groups faced with a novel task. (2) Fast Flippers were characterized by abrupt state changes in group function arising from internal or external disruptions. (3) Coasters were characterized by plateaus, where maintenance of group function was a frequently cited challenge. Abrupt changes and plateaus occurred more among mature groups and groups with significant PBL experience. CONCLUSIONS: PBL group function varies over time in 3 different patterns. Classic Tuckman's stages are apparent among inexperienced groups, or groups facing novel tasks, whereas experienced groups often face abrupt change or plateaus. PBL educators and students should consider the need for novelty and disruption in more experienced groups to incite growth.

Impact of the use of active methodology on the performance of undergraduate radiology students.

RATIONALE AND OBJECTIVES: Although PBL is widely used in several countries, especially in medicine courses, its application in teaching other higher education courses, which involve fundamentals applied to radiology, is still little explored. Therefore, we aim to evaluate the implementation of Problem-Based Learning (PBL) in a higher education institution's radiology and biomedicine technologist course, focusing on specific radiology-related disciplines. MATERIALS AND METHODS: An interventional study was developed with 78 students. An active methodology model was created and implemented for one of the groups of participants. At the beginning of each semester, students of both groups were evaluated with pre-tests. At the end of the semesters, the students performed a post-test and a validated evaluation of the discipline methodology. Repeated measures generalized linear regressive models with robust error estimators were used to evaluate test outcomes. RESULTS: A significant interaction among the methodologies was found (p=0.020), with better results from students exposed to the active methodology (initial and final grades were 7.18 and 7.57 in the active methodology, respectively, and 7.45 and 6.89 in the traditional methodology, respectively). In addition, students' evaluation regarding the quality of the methodology was favorable to the active methodology with statistical significance (p<0.05) in 16 of the 22 items evaluated. CONCLUSIONS: The students' positive response and performance were attributed to the interaction and innovation of the methodology compared to conventional methods, highlighting the effectiveness of PBL in higher education in radiology and its potential for more participatory and contextualized learning.
