PENGEMBANGAN MODUL KIMIA BERBASIS POE (PREDICT, OBSERVE, AND EXPLAIN) PADA MATERI SIFAT KOLIGATIF LARUTAN SEBAGAI SUMBER BELAJAR PESERTA DIDIK KELAS XII SMA/MA

Abstract

The development of POE-based chemical modules on the colligative properties of the solution aims to obtain a valid chemical module based on the content feasibility, language, graphics, and presentation aspects. The research method of developing chemical module using 4-D model consists of four stages: Define (define) stage, Design stage, Development stage and Desseminate stage. In this research only carried out until the development stage. Data collection techniques are using validation sheets given to two validators aim to assess the chemical modules that have been developed. The result of the research shows the acquisition of feasibility aspect of content 97.01%; 100% language feasibility aspect; aspect of 97.91% feasibility of aquality; and the feasibility aspect of 98.21% presentation. The average of validation score of all POE based chemical modules on the colligative properties of the solution is 96.7975% with very good category (very valid). Valid chemical modules are then tested to respondents. The respondents were limited to 4 chemistry teachers from SMA N 5 Pekanbaru and SMA N 8 Pekanbaru and 20 students from SMA N 5 Pekanbaru and SMA N 8 Pekanbaru. Analysis of user response data based on teachers 'sheets and learners' scored 93.667% and 89.53%. The overall avarege validation and limited validity testing scores stated that chemical modules based on POE can be used in the learning process.
