This study was carried out to observe, measure and analyze the effects of using software visualization in teaching programming with participants from two institutions of higher educations in Serbia. Basic programming learning is notorious for complex for many novice students at university level. The visualizations of examples of program code or programming tasks could help students to grasp programming structures more easily. This paper describes an investigation about the possibilities of enhancement of learning Java using the visualization software Jeliot. An analysis of 400 students’ test results indicates that a significant percentage of students had achieved better results when they were using a software visualization tool. In the experience of the authors Jeliot may yield the best results if implemented in with students who are new to the art of programming.

EWMA Algorithm in Network Practice

This study intends to measure the impact of interactive animations on the students’ performance. Two courses from Subotica Tech were included, the subjects “Analog and Digital Electronics” and “Microcontrollers”. The experiment lasted over a period of tree years, and it involved the formation of two groups in every academic. Both groups’ members participated in traditional frontal teaching, but the experimental group could use interactive Flash animations built from selected parts of those courses as supplementary tool. At the end of the semester, the exam marks were analyzed with a Two-Sample T-Test. The results show that learning with properly created interactive animations could have positive effects on most students’ academic performance.
