Abstract:

The background of this research is not optimal Chemistry learning in public high school because students still have difficulty in understanding the abstract chemistry . The lack of interest and motivation of students towards Chemistry subjects is a major problem to be solved. With the increasing ability ofmultirepresentation, students can more easily learn chemistry . The purpose of this study is to determine the effectiveness of the Advance Project Learning (APL) model to improve the ability of multirepresentation of students in learning chemistry in public high school. The research model used inthis study is Research and Development using Borg and Gall design which includes ten steps, namely preliminary study, planning, initial product development, limited test, revision of limited test results, large group test, revision of field trial results, feasibility test, revision of results feasibility test, dissemination and implementation. The results showed that the APL model is an effective model to improve the ability of multirepresentation.
