THE DEVELOPMENT OF BRYOPHYTA TEACHING BOOK FOR INCREASING THE STUDENTS’ UNDERSTANDING OF THE CONCEPT

Abstract

One of the determinants of learning success is the achievement of cognitive abilities or, commonly called, concept understanding. In fact, mastery of concepts based on the results of prior research at various levels of education is still relatively low. The results of observations on the subject of Low Plant Botany at the Biology Education Department FKIP Universitas Sulawesi Barat also showed that students' conceptual understanding was still low. This problem certainly requires a solution such as the implementation of a Low Plant Botany textbook that has been developed by the research team. The purpose of this study was to find out the stages of developing teaching materials based on the results of research in the first year of research, knowing the results of validation test by design experts, material experts, results of individual trials, trial results of readability of teaching materials, and to determine the effectiveness of development results textbooks for understanding student concepts. The method of developing teaching books in this study using the ADDIE Model which according to Branch (2009) consists of 5 stages, namely analysis (analysis), design (design), development (development), implementation (product implementation/ testing), and evaluation (evaluation). The results of this development study revealed that: (1) developed textbooks fulfilled valid criteria by the validators so that it was feasible to be implemented into the learning process, and (2) textbooks that had been developed by the research team proved effective in improving understanding the concepts of students.
