Abstract
This case study research aims to get a picture of students conceptions of heat transfer material. The population in this study are two classes of Science XI Muhammadiyah 4 High School Bandung. The sample used in this study is one class XI IPA II. Sample is determined by purposive sampling technique. The instruments used are in the form of test questions (three tier tests) and open interview guides. Data collection techniques are carried out by giving questions to students and giving open interview questions to teachers and student representatives. Data analysis is done by calculating the percentage of each students conceptual category and seeing the results of open interviews. The largest percentage of students conception categories is in the category of misconception, in all sub-material heat transfer percentage of misconception is the biggest. The following misconceptions were identified: (1) When thermal equilibrium still occurs heat transfer occurs so that the temperature of objects is different; (2) Objects that absorb heat more quickly, will be more slowly emit radiation heat; (3) In the case of conduction, heat flows because it is carried by molecules of intermediate substances that move; (4) In the event of heat transfer by convection, the rate of convection is faster when the water boils
