Abstract

Many studies have focused on students conceptions about the concepts of matter found that students from various levels of education have difficulty in comprehending the states and/or changes of matter. The present study aims to explore undergraduate students conception regarding the states and changes of matter. A total of 16 first to third year university students from physics education and science education department voluntarily participated in the study. We employed semi-structured interviews with each participant in order to elicit students conceptions and alternative conceptions regarding the states and changes of matter. Students were also prompted to make their own molecular illustration during the interview. The present study found that undergraduate students had difficulty in connecting between macroscopic and microscopic concept levels of the states and changes of matter. Furthermore, students developed several alternative conceptions in terms of temperature, volume, mass, and density of an object during phase changes. Undergraduate students also tended to give fewer explanation about transformation on liquid and gas phases due to poor understanding of particulate nature of liquid and gas, molecular bonds in particular. The study suggests the necessity of developing instruction with more contextual learning and the use of dynamic visual media to enhance undergraduate students' comprehensive understanding of the states and changes of matter.

Abstract

With advances in technology, learning physics must be supported by the use of media that are capable of representing physics concepts in macroscopic, symbolic, and microscopic. This study aims to explore students interpretation and response toward the three levels of representation-based visual media and its implementation in constructivist teaching sequence (CTS) about battery function in electrical circuit. The three levels of representation-based visual media consist of phenomena video, dynamic analogies, and microscopic models. The study involved 25 twelfth-grade students (14 female and 11 male) from a high school in Bandung, Indonesia. The content interpretation of visual media was qualitatively analysed through student worksheets. After the completing lesson, an attitude scale was administered to collect students response toward the three levels of representation-based visual media and its implementation. The findings of this study can assist physics teachers and researchers to develop innovative pedagogies that consider students interpretation ability to promote conceptual change learning
