Medical student education is challenging, and concept maps (CMs) can help students link new and existing knowledge, promote critical thinking and identify knowledge gaps.
To study the feasibility, acceptability, and effectiveness of CMs in problem-based learning (PBL) tutorials.
Students and tutors were randomized to tutorials that used or did not use CMs. A mixed-methods approach generated qualitative and quantitative results of participants' perspectives on and the effects of CMs in PBL tutorials.
Student survey response rate was 71% (122/172). Most students (82.6%) planned to use CMs in the future at least occasionally, and students in CM tutorials endorsed increased likelihood of using CMs in the future (p = 0.02) versus students in non-CM tutorials. Qualitative analyses identified consistent associations between CMs and recurrent themes: integration of physiological mechanisms, challenging students' knowledge of the material, and identification of knowledge gaps. Quantitative assessment of final exam scores revealed a statistically significant increase in the students' scores in CM tutorials versus students in non-CM tutorials with an a priori α of <0.10.
CMs are well accepted by students and faculty, feasible to incorporate into PBL tutorials, and may result in improved exam performance and student learning of physiologic concepts.
医学学生的教育具有挑战性,概念图(CMs)可以帮助学生链接新的和现有的知识,促进批判性思维,并识别知识空白。
研究基于问题的学习(PBL)教程中使用概念图的可行性、可接受性和有效性。
学生和导师被随机分配到使用或不使用概念图的辅导课中。采用混合方法产生了参与者对 PBL 辅导中概念图的看法和效果的定性和定量结果。
学生调查的回复率为 71%(122/172)。大多数学生(82.6%)计划将来至少偶尔使用概念图,而在概念图辅导课上的学生比在非概念图辅导课上的学生更有可能将来使用概念图(p=0.02)。定性分析确定了概念图和反复出现的主题之间的一致关联:生理机制的整合、挑战学生对材料的知识以及知识空白的识别。对期末考试成绩的定量评估显示,在概念图辅导课上的学生的成绩与在非概念图辅导课上的学生相比有统计学上的显著提高,事先设定的α值<0.10。
学生和教师都非常接受概念图,将其纳入 PBL 辅导课是可行的,并且可能会提高考试成绩和学生对生理概念的学习。
