Problem-based learning: let's not throw the baby out with the bathwater

Nursing students evaluation of problem based learning and the impact of culture on the learning process and outcomes: a pilot project

PURPOSES

This study evaluates students' learning experiences in a clinical pediatric nursing course adopting Problem Based Learning (PBL) and investigates how students' cultural background impacts on self directed learning.

METHODS

A mixed-methods approach combining quantitative and qualitative methods was utilized to answer the research objectives. An observational technique for the PBL teaching sessions was employed; and 226 third-year students were asked to complete PBL evaluation questionnaire.

RESULTS

Fifty seven percent (n = 130) responses to the questionnaire were analyzed. Overall, students considered PBL to be moderately effective in their learning experience, with a mean of 3.64 (S.D = 1.18). Students qualitative responses fell within four thematic categories including: developing cognitive abilities, independent learning, motivation to learn, and group learning. Difficulties encountered by students were: it is time-consuming, it has unclear objectives, it is a stressful process, and it results in an increased workload. A small number of students indicated that PBL tutorials were boring and complained about lack of contribution from instructors and limited recourses. Learning is intertwined with culture; students' previous educational experiences, uncertainty, English language proficiency, computer resources, gender, and achievement were identified as the most important cultural issues that impact the learning process and outcomes.

CONCLUSION

Successful implementation of PBL does not come easily; teachers should be alert to the issues of culture in designing curriculum.

Problem-based learning in academic health education. A systematic literature review

Problem based learning (PBL) arguably represents the most significant development in education over the past five decades. It has been promoted as the curriculum of choice, and since its introduction in the 1960's, has been widely adopted by many medical and dental schools. PBL has been the subject of much published literature but ironically, very little high quality evidence exists to advocate its efficacy and subsequently justify the widespread curriculum change. The purpose of this review is to classify and interpret the available evidence and extract relevant conclusions. In addition, it is the intent to propose recommendations regarding the relative benefits of PBL compared with conventional teaching. The literature was searched using PubMed, ERIC and PsycLIT. Further articles were retrieved from the reference lists of selected papers. Articles were chosen and included according to specific selection criteria. Studies were further classified as randomised controlled trials (RCTs) or comparative studies. These studies were then analysed according to intervention type: whole curricula comparisons and single educational interventions of shorter duration. At the level of RCTs and comparative studies (whole curricula), no clear difference was observed between PBL and conventional teaching. Paradoxically, it was only comparative studies of single PBL intervention in a traditional curriculum that yielded results that were consistently in favour of PBL. Further research is needed to investigate the possibility that multiple PBL interventions in a traditional curriculum could be more effective than an exclusively PBL programme. In addition, it is important to address the potential benefits of PBL in relation to life-long learning of health care professionals.

Revitalizing problem based learning: student and tutor attitudes towards a structured tutorial

BACKGROUND

The pre-clinical curriculum at the University of New Mexico School of Medicine is a hybrid model that includes small group, problem-based learning (PBL) tutorials and didactic lectures. A structured tutorial format was piloted for the human sexuality/reproduction organ system block for the PBL component. The objective of this study was to compare the acceptability of the structured format and its effectiveness with that of a traditional PBL tutorial.

METHODS

Students were surveyed after the renal/endocrinology block of 2004 (traditional tutorial format) and after the human sexuality/reproduction block of 2004 (structured tutorial format) (n = 70). Survey questions covered the quality of learning and of tutorial. Students (n = 132) and tutors (n = 24) who participated in human sexuality/reproduction in 2004 and 2005 were surveyed for attitudes about the structured tutorial overall and specific components. Means of responses were compared using t-tests.

RESULTS

Students indicated that the structured tutorial format supported a greater improvement in their basic science and clinical knowledge and their ability to evaluate information (p < 0.05). The majority of students and tutors recommended the structured format for tutorials in other blocks.

CONCLUSIONS

We demonstrated the acceptability of a structured tutorial format to students and faculty. Faculty members perceived greater depth of learning and participation by the students.
