Skillful surgical care demands proper patient assessment and decision-making. These skills are honed through long hours and years of clinical practice. A decrease in work hours is reducing the number of cases managed by medical students and residents. We have developed a set of interactive, web-based teaching modules to help fill this gap.
The modules aim to teach surgical decision-making in a convenient, nonthreatening manner. Surgical case material is presented in a graphically rich environment, including video and sound to enhance realism. At the end of each web-page, the user must make a management decision. The correct answer is subsequently provided with immediate feedback. Medical students used and evaluated the modules during their surgical clerkships. Additionally, students took a pretest and 1-week delayed posttest after completing the modules to assess the program's efficacy.
Eight modules involving pediatric and general surgery have been completed. Medical students gave high ratings to the quality of the modules and found the interactive format both engaging and educationally effective. Eighty-seven percent of medical students rated the program's educational value as above average to excellent. On pre- and posttest analysis, students' scores improved an average of 24.8% (P < 0.001).
Students enjoy web-based educational material. Additional modules covering a range of surgical topics are in development. Web-based modules appear to be an effective clinical teaching tool, well-suited for integration into the clinical curriculum.
精湛的外科护理需要对患者进行恰当的评估和决策。这些技能是通过长时间和多年的临床实践磨练出来的。工作时间的减少正在减少医学生和住院医师管理的病例数量。我们开发了一套基于网络的交互式教学模块来填补这一空白。
这些模块旨在以方便、无威胁的方式教授外科决策。外科病例材料在图形丰富的环境中呈现，包括视频和声音以增强真实感。在每个网页的末尾，用户必须做出管理决策。随后会提供正确答案并立即给出反馈。医学生在外科实习期间使用并评估了这些模块。此外，学生在完成模块后进行了预测试和1周后的后测试，以评估该项目的效果。
已经完成了八个涉及儿科和普通外科的模块。医学生对模块的质量给予了高度评价，并发现交互式形式既引人入胜又具有教育效果。87%的医学生将该项目的教育价值评为高于平均水平至优秀。在预测试和后测试分析中，学生的成绩平均提高了24.8%（P < 0.001）。
学生喜欢基于网络的教育材料。涵盖一系列外科主题的其他模块正在开发中。基于网络的模块似乎是一种有效的临床教学工具，非常适合融入临床课程。
