Abstract

With the rapid advancement of technology, it can encourage educators to continue to update the learning media used in transferring knowledge to students. The information re-assets of this have a look at have been three chemistry instructors and college students withinside the town of Padang.

The results of the research obtained from the data analysis that have been carried out show that the content of e-learning for the development of atomic theory using the Moodle application produced in this development research has content and construct validity levels of 0.89 and 0.87 with very categories. high and the level of practicality of 0.83 with a very high category. So it can be concluded that the content of e-learning for the development of atomic theory using the Moodle application on the material of atomic theory development is valid and practical.
