Pengembangan Modul Problem Based Learning pada Materi Asam Basa Kelas XI SMA/MA

Abstract

Generally, in the research method, there are several types of research. The type of research conducted is development research or Research and Development (R & D). This research aims to develop acid-base module based on problem based learning for learning class XI SMA / MA, and evaluate the categories of validity and practicality of the module. The development model used in this development is a 4-D model consisting of 4 stages, namely define, design, development and disseminate. The problem based learning acid base module is validated by 5 validators consisting of 3 chemistry lecturers from FMIPA UNP and 2 chemistry teachers at SMAN 1 Payakumbuh which using an instrument in the form of a validation sheet. Practical tests were carried out with 2 chemistry teachers and 33 students of class XII IPA 5 SMAN 1 Payakumbuh using instruments in the form of practical questionnaires. The results of the analysis of the validity, practicality of the teacher, and the practicality of the students showed that the average score of moment kappa (k) was 0.82, 0.88 and 0.80. The module is very valid and practical to use. Keywords : Acid Base, 4-D Models, Module, Practicality, Problem Based Learning, Research and Development (R & D), Validity.
