Mr. P. Gershom Jebaraj, Dr. K. Mohanasundaram

Abstract :

e–Contents are the powerful tool of education. e–Content is the latest method of instruction, which has attracted more attention of educationists. A study was undertaken to develop an e–Content on ‘Crystal Structures’ which is included in the First Semester Syllabus of Engineering Physics subject of “Anna University, Chennai, Tamil Nadu” and to validate the developed e–Content. A pre–test, post–test two group experimental design was adopted. Sample of 60 First Year Engineering students were exposed to different treatments such as teaching through e–Content and conventional method of teaching. The study was also focused on finding out the significant differences between control and experimental group of First Year Engineering students in their academic achievement while learning “Crystal Structures” with reference to gain scores. The achievement scores were analyzed using different statistical techniques. It was found that the experimental group students who were taught through e–Content material had better achievement scores than the control group students in learning “Crystal Structures”.
