Abstract
This study aims to develop a learning media in the form of a content learning system based on guided discovery learning on acid-base material in order to overcome problems in se learning to improve the learning outcomes of 11th-grade Senior High School students. The research method used is Research & Development (R&D) with the ADDIE model. The data used has been obtained through questionnaires and validation sheets. This content learning system has been validated by 3 chemistry education lecturers at Padang State University and 3 high school chemistry teachers. The validation data is then analyzed using the Aiken V formula. Based on the data analysis that has been carried out, it was found that the content learning system developed had high validity with a kappa value of 0.85. From the results of this validity, it can be argued that the content learning system that was developed is valid and can be continued to the practicality test for the purpose to be implemented in learning acid-base.
