Nascimento et al. Student video creation Extended data

This study involved students attending a Pharmacognosy course, which is part of a Pharmacy program, in a Brazilian University. During the first classes of the Pharmacognosy course, students were informed about the intention to conduct the study on the use of active learning methodologies coupled with technological tools and written informed consent was obtained. Three weeks after the beginning of the course, the professor applied a written test to evaluate the students’ previous knowledge about the use of herbal medicines. To investigate the impact of video production on students’ learning, they were randomly divided into two groups. The groups studied ‘the use of herbal medicines’ module using different learning strategies. One group (control) group continued to study in the conventional way, by listening to a four-hour lecture given by the professor. The other group (video intervention) was divided into teams that were instructed to produce a video lecture on the use of herbal medicines. After studying the use of herbal medicines using different approaches, students were once again assessed on their knowledge of the use of herbal medicines by a second written test. Then, the whole class watched the video lessons produced by students and filled out a questionnaire. A third test (the final exam) was applied at the end of the semester and evaluated all topics covered by the course.<br><br>This research was approved by the Research Ethics Committee registered through the Research Ethics Committees and the National Research Ethics Commission (approval number 13930013.6.0000.5058/244,173). Written informed consent from all the subjects involved was obtained.<br>

本研究的受试对象为巴西某大学药学专业生药学（Pharmacognosy）课程的学员。课程首堂课上，研究人员向学员告知了本研究拟采用主动学习方法结合技术工具开展研究的计划，并获取了全体学员的书面知情同意书。课程开始三周后，授课教师组织笔试，用以评估学员此前对草药应用的相关知识储备。为探究视频制作对学生学习效果的影响，研究人员将学员随机分为两组，两组采用不同学习策略完成“草药应用”模块的学习。其中一组为对照组，沿用传统学习模式，聆听授课教师时长四小时的讲座；另一组为视频制作干预组，该组被划分为若干小组，需自行制作一段关于草药应用的视频课程。在通过不同学习方式完成草药应用模块的学习后，研究人员再次通过笔试评估学员对草药应用的知识掌握情况，即第二次笔试。随后，全体学员共同观看了各组制作的视频课程，并填写了调查问卷。学期末，研究人员组织了第三次测试（期末考试），对课程涵盖的全部知识点进行综合考核。<br><br>本研究已通过研究伦理委员会（Research Ethics Committee）及国家研究伦理委员会（National Research Ethics Commission）的审批，审批编号为13930013.6.0000.5058/244,173。本研究已获取所有受试对象的书面知情同意书。
