e-Learning Development on Basic Chemical Law Materials in Senior High School (SMA/MA) to Improve High Order Thinking Skill Ability

This research aims to develop e-learning for learning Chemistry, Law of Basic
Chemistry, for Senior High Schools (SMA/MA). The method used is Borg and Gail. E
learning product development using the Moodle 3.75 application. The stage in the development
of this research is the content and construct validity of the product being developed. The result
obtained is an e-learning product of Basic Chemistry Laws which has very high content and
construct validity. From the results of the content validation, it was obtained 0.98 each for
Guidelines and information; 0.88 for Content / material; and 0.87 for Evaluation. From this
section, it can be seen that the content validity has a very high interpretation. From the results
of the construct validity includes guidance and information; Program Performance; and
Systematics, Aesthetics and Design principles respectively 0.84; 0.84; and 0.76. This section
looks very high, except for the systematic, aesthetic and design aspects which are still in the
high category. These results conclude that e-learning products have very high validity to be
used as learning materials for Chemistry in Senior High Schools (SMA) and Madrasah Aliyah
(MA), especially in the material of Basic Chemistry Laws.
