فاعلية قواعد بيانات وحدات التعلم الرقمية في توظيف خدمات الجيل الثالث للويب لدى طلاب الدراسات العليا
The aim of this research is to measure the effectiveness of databases of digital learning units in employing third-generation services for the web among graduate students, and the research followed the descriptive and experimental approach, and the sample consisted of (25) professional diploma students at the Faculty of Education, Mansoura University. It has one experimental group with pre and post measurement, where the databases of learning units were applied. The study tools consisted in an achievement test to measure the cognitive aspects of the third generation services, and a note card for the performance aspects of the third generation services. The results were processed using the “SPSS” statistical software package, and the research was conducted. For the following results: the presence of a statistically significant difference at the level (0.05) between the mean scores of the experimental group’s students ’scores in the pre and post applications of the cognitive achievement test for third-generation services for the Web in favor of the post application, and the presence of a statistically significant difference at the level of (0.05) between the mean of the students’ score ranks. The experimental group in the pre and post applications of the observation card in favor of the post application. It also appeared that the databases of digital learning units achieve effectiveness in employing Third-generation Web services for students have a value of not less than (1.2) when measured by the percentage of adjusted earnings for Black, and not less than (0.6) when measured by the effectiveness rate of Mac Geogian. This research also included discussing these results and providing an explanation for them. (Author’s abstract)
