Abstract


This research is a type of qualitative descriptive research that aims to capture conceptions and describe changes in the conceptions of prospective physics teacher students about the optical eye device after the implementation of the Conceptual Change Text (TPK). The steps taken were 1) Observation and definition, 2) Design of TPK, 3) screening of student conceptions, 4) implementation of TPK, 5) data analysis, and 5) interpretation of data on changes in student conceptions. The subjects of this study were 35 prospective physics teacher students who were programming Basic Physics II courses in the second semester of 2023 at the Physics Department, Faculty of Mathematics and Natural Sciences, Makassar State University. The results of this study indicate that on the working principle of the eye as an optical instrument, 72% experienced construction and 100% underwent reconstruction; the concept of the power of eye accommodation was obtained by 87% who underwent construction and 92% who underwent reconstruction; the concept of myopic eye defect as an optical device was obtained by 67% who underwent construction and 71% who underwent reconstruction; and the concept of hypermetropic eye defects obtained 85% who experienced construction and 58% who underwent reconstruction. It can be concluded that most student teacher candidates with different initial states of conception can achieve a deep and intact conceptual understanding through the process of construction (not having a conception to become a scientific conception) and reconstruction (misconceptions to a scientific conception).
