In the spring semester of 2020, colleges and universities adopted online teaching as the primary modality due to campus closure for social distancing. While lectures could be more readily converted to online classes, biology labs were challenging to handle since students could not physically conduct experiments in lab classrooms. In the present report, various online teaching materials, including educational and research videos, simulation labs, and real research data, were utilized to achieve the learning objectives of the originally in-person lab classes of an upper-level undergraduate genetics course. Furthermore, certain advantages of online teaching, such as detailed and high-quality annotation of lecture slides using the Apple Pencil and iPad, were observed. While online teaching has its unique strengths, it could not provide students with hands-on experience in performing real biology experiments to master technical skills; the latter are essential for students to develop a career in conducting research in an academic or industrial laboratory setting. Hence, a well-designed hybrid modality of using online teaching to complement conventional face-to-face instruction may allow for better teaching in undergraduate biology courses.

在春季学期2020年,由于校园关闭以保持社交距离,高校将在线教学作为主要方式。虽然可以更轻松地将讲座转换为在线课程,但由于学生无法在实验室教室中进行物理实验,因此生物学实验室很难处理。在本报告中,使用了各种在线教学材料,包括教育和研究视频,模拟实验室和真实的研究数据,以实现高级本科遗传学课程的原始面对面实验室课程的学习目标。此外,还观察到在线教学的某些优势,例如使用Apple Pencil和iPad对演讲幻灯片进行详细且高质量的注释。虽然在线教学有其独特的优势,但它不能为学生提供进行真实生物学实验以掌握技术技能的实践经验; 后者对于学生在学术或工业实验室环境中开展研究至关重要。因此,精心设计的使用在线教学来补充常规面对面教学的混合方式可能会在本科生物学课程中更好地进行教学。
