Large student numbers and heterogeneous teaching pools hamper standardized teaching and impede objective assessment of surgical skills. This article presents the advantages of new teaching media in a "blended learning" concept for training surgical skills to medical students at the Basel University Medical School in Switzerland.
The surgical skills course (suture course) for medical students was redesigned according to a blended learning concept consisting of an introduction with a multimedia CD-ROM, a practical course, and a skills lab. The learning targets of the course were evaluated through an objective structured clinical examination (OSCE) at the end of each study year. The students' own course evaluations were compared with the OSCE results before and after introduction of the new blended learning.
The students' evaluations with regard to teaching material, subjective practical achievement, prospective value for the practical year, and overall course evaluation were significantly higher than in the old course format. The proportion of passed OSCEs was 10% higher after the redesign of the course.
Blended learning can improve cognition and performance as well as the training efficiency and duration required for mentoring. Thus human resources can be saved indirectly. Surgical procedures may be presented more clearly.
学生人数众多且教学师资参差不齐,这妨碍了标准化教学,并阻碍了对外科手术技能的客观评估。本文介绍了瑞士巴塞尔大学医学院在“混合式学习”理念下,运用新的教学媒体对医学生进行外科技能培训的优势。
根据混合式学习理念,重新设计了面向医学生的外科技能课程(缝合课程),该理念包括使用多媒体光盘进行入门教学、实践课程以及技能实验室。在每个学年结束时,通过客观结构化临床考试(OSCE)对课程的学习目标进行评估。将引入新的混合式学习前后学生自身的课程评价与OSCE结果进行比较。
学生对教材、主观实践成绩、实习年度的预期价值以及整体课程评价均显著高于旧课程形式。课程重新设计后,OSCE考试及格率提高了10%。
混合式学习可以提高认知水平和操作表现,以及培训效率和指导所需时长。从而间接节省人力资源。外科手术过程可能会呈现得更加清晰。
