Diagnosis of Students Conception on Light and Optic Topics with Four-Tier Test a) Science Education, Indonesia University of Education Abstract Students^ conception is defined as the way students making sense of a range of natural phenomena. Identifying students^ conception is very essential because it leads to more focused teaching and enables teachers to prevent and eliminates misconceptions. The four-tier test is chosen because it is a stronger and more sensitive diagnostic test. Light and optic topics are chosen because it is an essential topic at school and there are repetitive misconceptions in these topics. Therefore, students^ conception on light and optic topics is diagnosed with the four-tier test in this research. The instruments were constructed from a list of indicators. The questions were administered online to 817 8th-grade students. Students^ conception is categorized into five which are scientific knowledge, false positive, false negative, misconception, and lack of knowledge. Frequencies and percentage are calculated with excel program and the data is further analyzed with Mann-Whitney U test to see if there is any significant difference between students who have learnt the topics and who have not. The result shows that that in general, students have more misconception than scientific knowledge, students did best in the formation of image on mirrors, students did worst in the optical instruments, and there is no significant difference between students who have learnt the topics and who have not. The causes are unconfronted misconceptions, online learning, and unfamiliarity. This indicates that teachers have to address common misconceptions in class, facilitating conceptual change by hands-on activities, and relate the concept with students^ daily life.
