Identification of Student Misconceptions Using a Four-Tier Diagnostic Test Based on Certainty of Response Index (CRI) in Dynamic Electricity Material at SMAN Unggul Pidie Jaya

Misconception is a concept that does not align with scientific concepts. Misconceptions among students need to be identified so that they do not hinder the understanding of subsequent material concepts. The purpose of this research is to determine whether there are misconceptions among students regarding dynamic electricity at SMAN Unggul Pidie Jaya; and to identify the misconceptions among students in the subtopics of dynamic electricity at SMAN Unggul Pidie Jaya. This study employs a mixed-methods approach. The subjects of this study are 27 students from class XII MIPA 1 at SMAN Unggul Pidie Jaya. The instrument used is a diagnostic test designed as a Four-Tier Multiple Choice Test accompanied by a Certainty of Response Index (CRI). The results of the data analysis show that the percentage of students who Understand the Concept (PK) is 19.17%, Do Not Understand the Concept (TPK) is 35.73%, Misconception (M) is 33.77%, and Error (E) is 11.33%. The percentage of misconceptions for each subtopic is as follows: electric current strength (37%), electrical resistance (44.4%), Ohm's Law (27.2%), series resistance (36.1%), Kirchhoff's Law (31.5%), direct current (18.5%), alternating current (14.8%), and electric power (38.9%). From the data analysis, it can be concluded that there are misconceptions among students in all subtopics of dynamic electricity at SMAN Unggul Pidie Jaya
