"Elearninging"When we intend to make an e-learning material about the experiment we have to know who will be the users so that to design the material accordingly. We have chosen two different user groups. The first group would be students at the secondary schools to complete their understanding on mechanics. The other group would be technical experts with a certain scientific background to refresh their knowledge, thus this part would be near to the popular science. As the expectations of the two groups are different, two independent materials have been constructed. Their structures are modular that allows us to recycle the elements in both materials reducing our work. One of the most important feature are the applied frame of reference. While the students' material works with inertial frame of reference, we have applied accelerated frame of reference (rotating Earth) in the case of experts. The challenge lies in the approach. The experiment itself is stunning for an expert. For a student without a massive background may be inconvenient and frustrating to follow old giant physicists. Neither the experiment nor the equipment are intriguing themselves but the way as Eötvös devised them once. Therefore it isn't worth reproducing the experiment by describing it. To provide the joy of discovery we give the equipment virtually to the students with a task. They are expected to find out the purpose and operation of it. It is a kind of backwards thinking. |
