THE IMPACTS OF MULTIMEDIA LECTURES ON STUDENTS' PERFORMANCE IN TWO SPECIFIC SUBJECTS

The objective of the work is to suggest pedagogical, economical and user-oriented criteria to identify benefits of multimedia lectures on mathematical methods in economics. Based on our previous work, we describe them and suggest how to evaluate them including scales and measures, if possible. Then we concentrate on the pedagogical criteria and show their utilization for the efficiency evaluation of the multimedia lectures. For this purpose, we divided the students into two groups based on the frequency of utilizing the multimedia lectures for their study, and used the methods of statistical analysis. In particular, we applied two-sample F-test to know whether the variances of students' results are significantly different or not and an appropriate version of the t-test to know whether mean values of students' results are significantly different or not. The case study is based on the data acquired form the students' performance measurement in two specific subjects taught in the Czech University of Life Sciences Prague in 2010 and 2011.
