This research belongs to Research and Development (R&D), a study that consists of four stages namely (1) defining, (2) designing, (3) developing, and (4) disseminating. This study was done until developing stage. The instruments used in this research were validity and practicality questionnaires. Validators of the product were four chemistry lecturers and three chemistry teachers. Both teachers and students in Public School 1 Lubuk Alung responded to practicality questionnaires. Data analyzed with kappa moment showed that discovery learning- based module had high degree of validity (mean score of kappa moment was 0.74), high degree of practicality from teachers’ perspective (mean score of kappa moment was 0.74), and very high degree of practicality from students’ perspective (mean score of kappa moment was 0.83). It can be concluded that discovery learning – based module was valid, practical and justifiable for high school chemistry instruction.
