Description Mental Model Students of Thermochemistry Basic Concept

Abstract


Thermochemistry is one of the material studied in chemistry which consists of abstract concept concepts because it discusses the energy that accompanies changes in physics or chemical reactions. The purpose of this study is to describe the mental models of students on the basic concepts of thermochemistry by using essay tests supplemented by interviews. A mental model is a concept in the minds of students that is used to describe and explain a phenomenon. The mental model of students in this study was classified based on five indicators of mental model assessment, which were complete mental models, incomplete mental models, misconceptions, no mental models, and no response. This type of research is descriptive research. Informants in this study were students of Education Class 23 people and 16 Non-Education class students one semester level two majoring in chemistry at the State University of Padang academic year 2015-2016. The instruments used in this study were essay tests and interviews. Data analysis technique used is percentage. The results of the study show that most students tend to only memorize chemical concepts related to symbolic levels and do not understand the meaning of the symbols used. Furthermore, most students have not been able to associate the observations at the macroscopic level with the symbolic level. students tend to be on the indicator of mental model assessment "there is no mental model", with the highest percentage of 87.5% means that students still do not understand most of the basic concepts of thermochemistry.
