Perceptions of radiography students toward problem-based learning almost two decades after its introduction at Makerere University, Uganda

Sociocultural factors affecting first-year medical students' adjustment to a PBL program at an African medical school

BACKGROUND

Besides regulatory learning skills, learning also requires students to relate to their social context and negotiate it as they transition and adjust to medical training. As such, there is a need to consider and explore the role of social and cultural aspects in student learning, particularly in problem-based learning, where the learning paradigm differs from what most students have previously experienced. In this article, we report on the findings of a study exploring first-year medical students' experiences during the first semester of an undergraduate problem-based learning medical program at an African medical school.

METHOD

We employed a qualitative case study approach using in-depth interviews with 23 first-year medical students. Participants ranged in age from 18 to 25 years. All students were bi/multilingual (some spoke three to five languages), with English as the learning language. We conducted an inductive thematic analysis to systematically identify and analyze patterns in the data using the Braun and Clarke framework.

RESULTS

Before medical school, students worked hard to compete for admission to medical school, were primarily taught using a teacher-centered approach, and preferred working alone. At the beginning of medical school, students found it challenging to understand the problem-based learning process, the role of the case, speaking and working effectively in a group, managing a heavy workload, and taking increased responsibility for their learning. By the end of the first semester, most students were handling the workload better, were more comfortable with their peers and facilitators, and appreciated the value of the problem-based learning approach.

CONCLUSIONS

Our study highlights the importance of interrogating contextual sociocultural factors that could cause tension when implementing problem-based learning in non-western medical schools. Adjustment to problem-based learning requires a conceptual and pedagogic shift towards learner-centered practice, particularly concerning self-direction, the role of the case, and collaborative learning. As such, there is a need to develop and implement research-informed learning development programs that enable students to reflect on their sociocultural beliefs and practices, and enhance their regulatory learning competence to optimize meaningful and early engagement with the problem-based learning process.

A model to facilitate critical thinking of radiography students

INTRODUCTION

Critical thinking is a much-needed skill required by radiography students, across disciplines, when they graduate. The facilitation of critical thinking is a task that radiography educators are faced with in order to produce graduates who can apply these skills in the clinical setting, for the best care of the patient. The development of critical thinking skills is challenging, and currently there is no radiography-specific model which has been implemented and evaluated as a framework of reference for radiography educators. The aim of this article is to present a critical thinking model as a framework of reference that was implemented and evaluated by diagnostic radiography educators.

METHODS

A theory-generating qualitative, exploratory, descriptive and contextual design was used for the development of a model to facilitate critical thinking skills of diagnostic radiography students in a South African setting.

RESULTS

A theory-generation model to facilitate critical thinking skills for radiography students was developed. The model was implemented and evaluated by radiography educators. Three themes emerged from the evaluation of the model after implementation. The results indicated the implementation of the model provided a platform for radiography educators to collaborate and purposefully tailor activities to incorporate critical thinking into their teaching.

CONCLUSIONS

Through the implementation of the model, radiography educators felt empowered by using a framework of reference to facilitate critical thinking skills of radiography students.

Problem-based learning in medical radiation science education: A scoping review

INTRODUCTION

The current educational and technological environment in medical radiation science is dynamic. Educators must seek both proven and contemporary methods to ensure graduates are equipped for the clinical environment. This scoping review sought to assess the evidence regarding the value of problem-based learning (PBL) as part of medical radiation undergraduate curricula.

METHODS

A systematic search of Medline, Emcare, and CINAHL was undertaken. Studies using both quantitative and qualitative methodologies were eligible if they reported the outcomes relating to PBL intervention for medical radiation science students in undergraduate education (diagnostic radiography, radiation therapy, or nuclear medicine). Outcomes included self-perceived benefits, disadvantages, and skills. Screening and data extraction was conducted independently by two reviewers.

RESULTS

Eleven studies were included. Data regarding perceived benefits, perceived disadvantages, and skills were gathered. Pre-post studies demonstrated statistically significant findings suggesting better preparedness and improved attitudes for PBL students. Across institutions globally, there is evidence suggesting PBL is positively received by medical radiation students. High satisfaction was experienced amongst participants. Negative feedback included lack of resources, limitations in realism, and issues associated with groupwork.

CONCLUSION

PBL may positively impact student satisfaction, knowledge acquisition, and skills, though this necessitates further research.

IMPLICATIONS FOR PRACTICE

Medical radiation is an evolving discipline, and problem-based learning poses an educational tool to equip graduates with adaptive qualities.

Effectiveness of problem-based learning methodology in undergraduate medical education: a scoping review

BACKGROUND

Problem-based learning (PBL) is a pedagogical approach that shifts the role of the teacher to the student (student-centered) and is based on self-directed learning. Although PBL has been adopted in undergraduate and postgraduate medical education, the effectiveness of the method is still under discussion. The author's purpose was to appraise available international evidence concerning to the effectiveness and usefulness of PBL methodology in undergraduate medical teaching programs.

METHODS

The authors applied the Arksey and O'Malley framework to undertake a scoping review. The search was carried out in February 2021 in PubMed and Web of Science including all publications in English and Spanish with no limits on publication date, study design or country of origin.

RESULTS

The literature search identified one hundred and twenty-four publications eligible for this review. Despite the fact that this review included many studies, their design was heterogeneous and only a few provided a high scientific evidence methodology (randomized design and/or systematic reviews with meta-analysis). Furthermore, most were single-center experiences with small sample size and there were no large multi-center studies. PBL methodology obtained a high level of satisfaction, especially among students. It was more effective than other more traditional (or lecture-based methods) at improving social and communication skills, problem-solving and self-learning skills. Knowledge retention and academic performance weren't worse (and in many studies were better) than with traditional methods. PBL was not universally widespread, probably because requires greater human resources and continuous training for its implementation.

CONCLUSION

PBL is an effective and satisfactory methodology for medical education. It is likely that through PBL medical students will not only acquire knowledge but also other competencies that are needed in medical professionalism.
