In the field of engineering many technical concepts exists which are complex to teach without proper guidance. Guidance in this sense, means a tool which helps to simplify the learning, impart the knowledge and frequently checks the knowledge retention. It is not always a rule that we must use 3D diagrams and models to explain the engineering concepts which makes the eLearning production cost considerably higher. Also not all youtube type videos are good enough to be considered as effective teaching/training material. The number of hits a training video can be indirectly interpreted as a learner struggling to understand the video by visiting multiple times, forget about how many times the learner used the play/pause/reload options. Know yourself, play with the parameters, explore further are some of the strategies we apply in developing eLearning courses for technical concepts and systems.
