Usefulness testing of the Interactive Tool for Teaching Transformations

The Interactive Tool for Teaching Transformations (I3T) program was created to help students understand the complex concepts of graphical transformations. This thesis aims to test the usefulness of this program and investigates whether it is suitable for inclusion as a teaching tool in computer graphics courses. Based on an analysis of the I3T program, specific topics were selected in which the I3T tool could help students due to its ability to interact and visualize. Furthermore, a testing process of the usefulness of this program was created, and the results were evaluated using 80 sets of answers. Quantitative tests were designed to test the tool's utility in the selected graphic topics. For the same topics, new exercises were designed into the teaching program. Six new exercises which improve students' knowledge of transformations used in computer graphics were created as part of the bachelor thesis. The main result is the preparation and implementation of testing the effectiveness of I3T in teaching. Quantitative tests have confirmed that I3T helps in teaching geometric transformations and is more effective than traditional teaching methods. The results of students who used I3T during the seminar were 9 percent better than those of students who attended traditionally taught seminar. These values can be seen from the measured values, where the average improvement of the I3T group was 2.77 out of 22 points, while the improvement of the whiteboard group was only 0.79 points.
