Inspite of few limitations the video-instructional package was evaluated by all the experts to be  a laudable attempt in presenting environmental education for the students of Gujarati medium .24. The majority of the students found the package knowledgeable ,innovative , systematic and interesting .Most of the students of standard -IX of Surat -city as well as of Surat-rural likedand enjoyed learning through Video-instructional package .They were also ready to use such packages in future for other Subjects , too .

Educational Implications of the Study.

The results of the present study indicates that teacher made video-instructional packages can be used effectively for creating awareness and providing information to school students. Therefore ,such more attempts should be taken for some other important aspects of life as per the needs of the students . It could be used as an instructional system in both formal as well as in non - formal situation. The present study also recommends regarding the organization of the training programmes and work shop for teachers where development of software specially for video package can be learnt and made by the teachers .The study has also implications for administrators, principals, teachers and students for better planning the teaching - learning process .
