Z-Test-Based Analysis for Validating the Effectiveness of NPTEL E-Learning Modules

Abstract

The present article proposes use of a z-model to validate learning progress after experimenting on student’s performance. A statistical map of z-values is used to calculate the z-value. This paper is divided into two parts - First examine the students' learning outcomes in various computer science and engineering (CSE) subjects during regular classroom instruction as well as examine the students by an interactive learning model in which traditional classroom instruction and e-learning modules are combined and then, the second part administers a related exam to the same group of students. Z-test is used as a tool for evaluating the results. Based on the findings we found that students' performance increased dramatically after incorporating an e-learning module into their classroom instruction. The e-learning module has now been introduced into the classroom. Each subject would have a separate test paper with a higher degree of difficulty. It has been found that a substantial increase in the learning outcome of the students after Appling the proposed approach.
