Development of HATRADI : a four tier test for diagnostic student misconception in heat transfer concept

Abstract

Heat transfer concept is an abstract concept that creates misconceptions. Misconception is an understanding of a concept that is contrary with theory of scientists, if not immediately diagnosed it will cause a prolonged chain of misunderstandings. Diagnostic tests are one solution to identify these misconceptions. This research aims to develop a multiple choice four-tier test instrument for diagnose and identify student misconceptions on heat transfer concept. The research method used is the R&D research method with a 4D research design. The research was conducted at a school in Bandung with a sample of 60 students who were selected by purposive sampling technique. HATRADI is a diagnostic test item to capture students' misconceptions on heat transfer concept. The results of the research stated that HATRADI was a valid and reliable instrument with a very high category. So it can be concluded that HATRADI is a four tier test instrument that is feasible to assess and identify student misconceptions on heat transfer concept.
