Conventionally it is difficult to open up an engine to show how it functions. Also like PowerPoint presentations video files can also be stored in database for references. iii. Having Forum Discussions Forums are one of the best tools where we can have teacher student interaction at any time whenever needed. Implementing forums
about the information he needs in his professional courses. A teacher can post a topic or throw a question on relevant topics of the curriculum and students can answer or vice

discussion is that every student presents the answer in his own way. May it be wrong or right is secondary, but at the end of the discussion a refined answer is ready for the question posed. This gains confidence in the students and students fare well in the examinations. To develop the interest of student in the subject continuous evaluation can be implemented on the topic discussed in the forum. This develops zeal to learn in every student. iv. Social Media Learning Faculties of technical institutions are big users of and believers in social media. Virtually all higher education teaching faculties are aware of the major social media sites. According to Moran et al [5] majority of them believe that video, podcasts, and wikis are valuable tools for teaching, and a majority report that social media sites can be valuable tools for collaborative learning.
Collaborating E-Learning in Demonstration of Mechanical Practical for Engineering Students IV. HOW E-LEARNING BENEFITS THE ENVIRONMENT. With the aid of e-learning module in the curriculum of technical universities we have lot of boons rather than banes. Let us take an example: A regular semester of engineering course in India comprises of 16 weeks. The course of mechanical engineering per semester has five theory subjects of 52 hours each and two practical subjects of 42 hours each. Total comes to 94 hours of learning per semester. Let us take 100 students per semester attend the class. We can have 25% of the curriculum

effectively 71 hours of blackboard learning and 23 hours of e-learning. Now there are eight semesters running simultaneously per year in an engineering college. Hence we
attend lecture. This can save the overhead and operating cost of the institution thereby bring drastic change in the environment. When just a single discipline of engineering can have such an impact on the environment, then what could the impact be if the institute as a whole is considered? In the one of the territory state of India like Karnataka where there about 200 technical institutions, and if e-learning is implemented in these institutes, it can bring drastic environmental changes thereby reducing global warming and hence the economic crunch is dissolved. The implementation of e-learning for the whole nation and projecting it to the whole world can have a very positive impact on the learning at comfort zones, expenditure and pollution. We bet this is the best that humanity can gift Mother Nature.
