DEVELOPMENT OF SCIENCE LEARNING DEVICES IN THE TOPIC OF THE SCIENCE OBJECT AND ITS OBSERVATION

Abstract

2013 Curriculum Learning requires an educational process that provides opportunities for students to develop all their potential. For this potential to develop well, the teacher must be able to position himself as a guide and facilitator for students. The low level of critical thinking skills of students results in the slow development of potential within students. Therefore, efforts need to be made by the teacher to help students in developing critical thinking skills. One effort that can be done is to develop a learning tool that is expected to be able to improve critical thinking skills by applying a guided inquiry learning model. Research on the development of learning devices aims to produce integrated learning tools that are valid, practical and effective. The development research method follows a procedural development model at the preliminary research stage and applies the Mafumiko design at the formative evaluation stage. The development research subjects were experts, partner teachers, and seventh-grade students of SMPN 22 Banjarmasin, academic year 2017/2018. Data analysis was carried out descriptively through a categorical system. The results showed that: 1) the validity of the device based on expert judgment fulfilled the valid category, readability of teaching materials, LKPD and item items included in the good category, 2) the practicality of learning devices fulfilled the good category, and student responses were very positive, 3) the effectiveness of learning devices shown from the increase in cognitive learning outcomes and improvement of students critical thinking skills. Psychomotor performance, teacher activity, and student activities fulfill good categories.
