DEVELOPING OF CONCEPTUAL CHANGE TEXTS (CCTs) BASED ON CONCEPTUAL CHANGE MODEL TO INCREASE STUDENTS’ CONCEPTUAL UNDERSTANDING AND REMEDIATE MISCONCEPTIONS INKINEMATICS

Abstract

The main objectives of this research are to develop a valid and practical Conceptual Change Texts (CCTs) material related to Newtonian Mechanics and to test the influence of the CCTs in order to increase students’ conceptual understanding and overcome their misconceptions in the relevant topics. The research is divided in to two years comprising of three steps, namely 1) preliminary study, 2) design development, and 3) product testing. This article reports some result of the first year research for kinematics materials. The method for the first and the second steps are descriptive qualitative and development research, respectively. Based on the analysis of the preliminary data it is found the weakness of the basic and standard competencies for Newtonian Mechanics materials in Basic Physics 1 course and it has been changed from 7 to 9 standard competencies. It was also arranged essential material and found 9 common misconceptions in kinematics, namely velocity and acceleration are considered equal, position and velocity are considered equal, velocity is not as vector quantity, ego-centered reference frame, heavier objects fall faster, gravity increase as an object falls, acceleration differs along the trajectory of a projectile motion, an object thrown vertically upward from a linier moving object will land behind this moving object, and a bullet will not hit a target if the target falls downat the same time the bullet is fired. These findings are basis to develop the CCTs. It is developing the CCTs for kinematics comprises of: case, question(s), space to answer and reason, kinds of misconceptions, and explanation of the right concepts. The CCTs in turn can be utilized to improve learners’ conceptual understandings and to remediate their misconceptions toward the truer concepts in the Kinematics topics.
