 Everyone, some interest in research I found over the weekend and I guess I've been looking at online video content for study skills and for revision more and more since the pandemic. This paper was published I think it was late 2022. It's looking at short instructional videos for the TikTok generation. One or two of you might have spotted me share this over the weekend and I'm reading the full paper and I'm writing a short blog summary with some recommendations for teachers but essentially what we've got in this is approximately 230 students divided into an experimental group and a control group. In the experimental group the students were exposed to four or five short two-minute videos compared to the control group which had an online lecture with their teacher where they followed through the materials together and worked through different problems so I guess in some respects maybe traditional teaching and actually the effect size of this so this is in a mathematic context in a university so undergraduates. So effect size 2.15 but actually the kind of conclusions that I've kind of read so far is that TikTok videos at least allow students to focus intently in short bursts and where the the kind of teaching team and the IT support had designed attractive short instructional videos. One it needed a coordinated effort so it was approximately 40 40 hours of work and it's there was quizzes to self-test students but even the students that took part in the experiments still needed some teacher help so I guess the question I've got for you all is which schools out there have a revision TikTok channel or a YouTube channel and are the videos 2, 3, 4, 5 minutes long or even longer and for those schools that have two-minute videos out there in abundance are you getting better outcomes than everybody else?
