Abstract: The subject of this study is the influence of multimedia on the development of motivation for learning among schoolchildren. A study was conducted on the basis of MBOU Lyceum No. 8 in Krasnoyarsk among students of two ninth grades. In the course of the study, the following methods were used: studying the motivation of M.I. Lukyanova's teaching; determining the level of motivation of N.G. Luskanova's teaching, interviewing teachers and students. Prior to the experiment, the level of motivation among the students of the control and experimental groups was measured, which corresponded to the level of "low" and "medium" for 46 and 52% of respondents, respectively. After the experiment, when more than 100 chemistry and biology lessons were conducted for two quarters, the level of motivation in the experimental group increased according to the indicators "high" and "very high" according to the results of two methods. thus, after conducting an experiment with the use of multimedia technologies in the classroom in the experimental group, there is a decrease in the number of students with low and very low levels of educational motives. The main conclusions of this study are related to the fact that as a result of the study, it was proved that the level of motivation for learning among schoolchildren increases when using multimedia technologies in the classroom, such as multimedia presentations, audio and video clips, electronic textbooks, interactive whiteboards and online testing. The study revealed an increase in academic performance in the experimental group. Academic performance in this group has increased due to an increase in the level of motivation for learning among schoolchildren. According to the results of the study, it can be concluded that the use of multimedia technologies contributes to an increase in the level of motivation for learning and, therefore, directly affects the academic performance of students.
