Evaluation of the impact of changing the number of test tasks on successful completion for automated LMS

Based on the directions for time criteria optimization obtained by previous research related to LMS automated assessment, the task corpus was increased to ensure better class material coverage. In actual academic year on Personal Computer Applications (PCA) course in professional study of electrical engineering at Zagreb University of Applied Sciences, results from exams with the new parameters, were obtained. Statistical data analysis was carried out with the focus on the following explanatory parameters: number of students solving test, number of successful attempts, characteristic duration of test and overall test duration. Results of abovementioned analysis, presented in the paper, give the possibility for quantitative estimation how the changed parameters affect the test dynamic solving and the success of passing the exam.
