ABSTRACT
Preliminary observation in three universities revealed that its focus remains on the level of knowledge, understanding, and application. The aims of the research were to explore and to describe the consistency of students’ understanding of thermal conductivity concept, whereas the testing instruments were adapted from HTCE (Heat and Temperature Concept Evaluation). The study was carried out in three higher learning institutions: IKIP PGRI Madiun, UIN Sunan Kalijaga Yogyakarta, and Lampung University with a sample of 145 students. Descriptive research design was employed, while the purposive random sampling technique was used to obtain the sample. Data were obtained using multi-representation tests and in-depth interviews. Based on the data analysis, it was found that 87.59% students were inconsistent to answer testof multi-representation concept.
