A study involving 148 university students examined the effects of handout availability on note-taking during lectures and on post-lecture explanations of lecture content. Two classes received the same lecture content: one class was provided with lecture slides as handouts, while the other was not. The results showed that the group without handouts took more notes than the group with handouts, which was considered to be due to copying information directly from the slides. In addition, when students were asked to explain the lecture content after the class, there was no difference in the amount of information explained between the two groups. However, the handout group tended to verbalize annotations such as boxes and arrows and explain the content in their own words, whereas the no-handout group appeared to make greater use of information they had independently added to the slide content.
