JoVE Videos Better Prepare STEM Students for Laboratory Classes; Boost Confidence, Retention and Test Scores. Student Benefits Increase as Class Material Becomes More Complex.

Students who watch JoVE Science Education videos before biology laboratory class score up to 100% higher on assessments than students who just read text materials, according to the results of an independent study being released today.

The study also showed that up to 96% of students who watched a video pre-class felt more confident in their understanding of the lab requirements, key concepts and techniques required to conduct the lab experiment. The positive impact of JoVE Science Education videos on student performance increased as the topics assigned for study became more complex.

The study was conducted by the non-profit education research organization TERC, based in Cambridge, Mass. Teaching faculty and 346 students at Clemson and DeSales Universities participated in the IRB-approved study during the Fall 2017 semester.

The goal of the study was to evaluate what impact watching a JoVE video ahead of their science laboratory classes had students’ performance and confidence. Investigators measured and compared the performance between students who prepared for a hands-on experiment in class by watching about five minutes of a corresponding JoVE video two times, in addition to their typical text assignments, and control groups who only used the text handouts to prepare for their upcoming laboratory class.

For example, molecular biology students in the video group at DeSales University watched a JoVE Science Education video ahead of a lab on conducting plasmid purification - a molecular biology technique used to isolate and purify DNA. These students scored 100% higher than the control group that didn’t watch the video on quizzes before the lab, and then 76% higher again after both groups conducted the lab.

DeSales students reported that they felt JoVE videos had a significant positive impact on their studies:
89% of the students reported being more confident in the laboratory environment
92% of the students felt they better understood the techniques involved in the upcoming experiment
96% of the students found JoVE videos helpful in understanding key scientific concepts

"JoVE videos stand out for their brevity. My students’ attention is short, and lab time is precious. I found that the JoVE videos covered the most essential information and kept the students' attention, and it showed in the results," noted research lead Dr. Lara Goudsouzian, assistant professor in the Natural Science Department at DeSales University.

“These studies validate the feedback that we’ve received from professors at 1,000 academic institutions that subscribe to JoVE,” said Moshe Pritsker, JoVE’s CEO and co-founder. “Professors value our concise, easy-to-use videos for teaching, and see dramatic student gains when they include our videos in their curricula. Improving student performance in science classes by up to 100% takes as little as 15 seconds - the time it takes to send a student the link to a JoVE Science Education video.”
