16. Intelligent Database Systems Lab Experiments-Analysis of active and passive students’ perspectives 15

17. Intelligent Database Systems Lab Conclusions The UEVL system was accepted by the students in the sample. Active students were more concerned about the perceived usefulness of the system, while passive students were more concerned about the perceived ease of use of the system. 16

18. Intelligent Database Systems Lab Comments Advantages – Students can promote their English vocabulary ability and learn vocabulary more efficiently. Applications – Instructional software. 17
