We use different methods to train our undergraduates. The patient-oriented problem-solving (POPS) system is an innovative teaching-learning method that imparts knowledge, enhances intrinsic motivation, promotes self learning, encourages clinical reasoning, and develops long-lasting memory. The aim of this study was to develop POPS in teaching pathology, assess its effectiveness, and assess students' preference for POPS over didactic lectures.
One hundred fifty second-year MBBS students were divided into two groups: A and B. Group A was taught by POPS while group B was taught by traditional lectures. Pre- and posttest numerical scores of both groups were evaluated and compared. Students then completed a self-structured feedback questionnaire for analysis.
The mean (SD) difference in pre- and post-test scores of groups A and B was 15.98 (3.18) and 7.79 (2.52), respectively. The significance of the difference between scores of group A and group B teaching methods was 16.62 (P < 0.0001), as determined by the z-test. Improvement in post-test performance of group A was significantly greater than of group B, demonstrating the effectiveness of POPS. Students responded that POPS facilitates self-learning, helps in understanding topics, creates interest, and is a scientific approach to teaching. Feedback response on POPS was strong in 57.52% of students, moderate in 35.67%, and negative in only 6.81%, showing that 93.19% students favored POPS over simple lectures.
It is not feasible to enforce the PBL method of teaching throughout the entire curriculum; However, POPS can be incorporated along with audiovisual aids to break the monotony of dialectic lectures and as alternative to PBL.
我们采用不同方法培养本科学生。以患者为导向的问题解决(POPS)系统是一种创新的教学方法,它传授知识、增强内在动力、促进自主学习、鼓励临床推理并培养持久记忆。本研究的目的是在病理学教学中开发POPS,评估其有效性,并评估学生对POPS相对于传统讲授法的偏好。
150名医学学士二年级学生被分为两组:A组和B组。A组采用POPS教学,而B组采用传统讲授法教学。对两组的课前和课后数值分数进行评估和比较。然后学生完成一份自我构建的反馈问卷进行分析。
A组和B组课前和课后分数的平均(标准差)差异分别为15.98(3.18)和7.79(2.52)。通过z检验确定,A组和B组教学方法的分数差异显著性为16.62(P < 0.0001)。A组课后成绩的提高显著大于B组,证明了POPS的有效性。学生们表示,POPS有助于自主学习、有助于理解主题、激发兴趣,是一种科学的教学方法。对POPS的反馈,57.52%的学生反应强烈,35.67%的学生反应适中,只有6.81%的学生反应消极,表明93.19%的学生更喜欢POPS而不是单纯的讲授法。
在整个课程中强制推行基于问题的学习(PBL)教学方法是不可行的;然而,POPS可以与视听教具结合使用,以打破辩证讲授的单调,并作为PBL的替代方法。
