Development of Chemistry Learning Intruments Based on Reading Questiong and Answering Strategy Mixed with Creative Problem Solving

Abstract

This study aims to produce chemistry learning intruments based on Reading Questioning and Answering RQA strategy mixed with Creative Problem Solving (CPS) on acid-base topic to improve students' critical thinking skills. The product development is based on the 4D model which is limited to 3 stages: define, design and develop. The feasibility test of learning instruments was carried out. The percentage of the feasibility of the syllabus, lesson plan, eligibility of student worksheet, and the percentage of critical thinking instruments are 80 %, 77 %, 82 %, and 75 %, respectively. The total percentage of all developed instrument items is 78.8 %. In conclusion, feasibility study shows that the chemical learning intruments based on RQA-CPS is categorized as feasible.
