A basic bacteriology course was offered in two successive academic years, first in a conventional format and subsequently as a "hybrid" course. The latter combined (i) online presentation of content, (ii) an emphasis on online resources, (iii) thrice-weekly, face-to-face conversations to advance understanding, and (iv) frequent student postings on an electronic discussion board. We compared the two courses through statistical analysis of student performances on the final examinations and the course overall and student assessment of teaching. The data indicated that there was no statistical difference in performance on the final examinations or the course overall. Responses on an instrument of evaluation revealed that students less strongly affirmed the following measures in the hybrid course: (i) The amount of work was appropriate for the credit received, (ii) Interactions between students and instructor were positive, (iii) I learned a great deal in this course, and (iv) I would recommend this course to other students. We recommend clear direction about active learning tasks and relevant feedback to enhance learning in a hybrid course.
在连续两个学年开设了基础细菌学课程,第一年采用传统授课形式,随后作为“混合式”课程授课。后者结合了:(i)内容的在线呈现,(ii)对在线资源的强调,(iii)每周三次的面对面交流以促进理解,以及(iv)学生频繁在电子讨论板上发帖。我们通过对学生期末考试成绩、课程整体表现以及学生对教学的评估进行统计分析,对这两门课程进行了比较。数据表明,期末考试成绩或课程整体表现不存在统计学差异。一份评估工具的反馈显示,在混合式课程中,学生对以下几点的肯定程度较低:(i)作业量与所获学分相符,(ii)学生与教师之间的互动积极,(iii)我在这门课程中学到了很多,(iv)我会向其他学生推荐这门课程。我们建议在混合式课程中明确关于主动学习任务的指导以及提供相关反馈,以加强学习效果。
