Abstract

Some teachers specifically conceive and use the concept of volume, but students attribute their specific meanings to the concept of volume depending on their personal experience and the nature of the activity they are doing. This study aimed to identify students' mental models regarding the concept of volume In this study, a researcher-made questionnaire was used so that 57 high school students from seventh, eighth and ninth grades (23 person seventh, 12 person eighth, 22 person ninth) in the 98-99 academic year participated in this study, of which 25 students were purposefully selected for the interview By interviewing and reviewing the answers of students it was determined that the students' mental models regarding the concept of volume can be classified into six categories. In the first group, the volume is related to the weight of the object, and in the second group, the volume was considered as the capacity of the object (empty space inside the object), and in the third group, the volume was thought to be the fullness of the object. In the fourth category, volume was defined as the space occupied by the object, and in the fifth category, volume was considered dependent on geometric properties (length, width, height and size), and in the sixth category, volume was dependent on other factors (in Closure of the object. Air flow in the object. The amount of substance added to the object. Having four corners in the object. Having atoms.
