Online case-based learning (CBL) is a method used by King Abdulaziz University to teach medical students in their preclinical years. The use of CBL in basic sciences is important for enabling medical students to correlate basic sciences with future clinical practice. This study implemented online CBL for biochemistry teaching as part of the medical genetic module for 3rd-year preclinical students. Teaching during the study was completely online because of restricted precautions caused by the COVID-19 pandemic, except for practical sessions that were held on campus. The case was presented to the students involved in prenatal screening and diagnosis. Students were guided to learn and discuss the biochemical tests used for prenatal screening and diagnosis and their clinical importance. They were divided into two groups: the control group was given an online lecture and the intervention group was given an online CBL session before the lecture. The online lecture was given to both groups simultaneously by the same instructor, and then 10 MCQs tests were distributed to both groups after the lecture, and their test scores were compared. A 10-question survey was administered to the intervention group to assess their perception of the online CBL session after the test. A significant difference was found between the intervention and control groups regarding test scores (p < 0.001), and most students found the online CBL session enjoyable and motivating.

在 COVID-19 大流行期间，阿卜杜勒阿齐兹国王大学将基于案例的在线学习作为医学生生物化学的教学方法（一项于 2021 年进行的研究）


在线基于案例的学习（CBL）是阿卜杜勒阿齐兹国王大学在临床前阶段对医学生进行教学的一种方法。 CBL 在基础科学中的使用对于使医学生将基础科学与未来的临床实践联系起来非常重要。本研究实施了生物化学在线 CBL 教学，作为三年级临床前学生医学遗传学模块的一部分。由于COVID-19大流行造成的预防措施有限，研究期间的教学完全在线进行，除了在校园内举行的实践课程外。该案例被介绍给参与产前筛查和诊断的学生。指导学生学习和讨论用于产前筛查和诊断的生化测试及其临床重要性。他们被分为两组：对照组接受在线讲座，干预组在讲座前接受在线 CBL 课程。在线讲座由同一位讲师同时向两组进行，然后在讲座结束后向两组分发 10 份 MCQ 测试，并比较他们的测试成绩。对干预组进行了一项包含 10 个问题的调查，以评估他们在测试后对在线 CBL 课程的看法。干预组和对照组之间的测试成绩存在显着差异 ( p < 0.001)，大多数学生认为在线 CBL 课程令人愉快且具有激励性。
