다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate middle school student`s conceptual change about Force and Motion by the courseware based on constructivism. It is well known to science educators that misconcrptions about physics concepts are hardly changed into scientific ones. So as to change student`s misconceptions about force and motion, the courseware was developed through the analysis of students` conceptions. 20 students were tested before and after learning through the courseware. One of the questions was about the direction of force acting on the ball thrown in the air when it is rising, at the top, and falling. The other was about the magnitudes and directions of forces acting on a car when it is accelerating, in uniform velocity, and decelerating. The results are as follows: In case of vertical motion, all students had misconceptions before learning, but after learning 5 students(25%) have changed their ideas into scientific ones. In case of horizontal motion, 9(45%) out of 24 students who had misconceptions about force and motion have changed their ideas into scientific ones.
