Abstract

This study aims to develop a valid and reliable assessment instrument to measure students' higher-order thinking skills in the context of acid-base chemistry. The research employed a Research and Development (RD) approach using the 4-D model, which includes the stages of Define, Design, Develop, and Disseminate. The initial product was validated through expert judgment, evaluated for feasibility by chemistry teachers, and subjected to field testing. The study involved 200 twelfth-grade science students from SMAN Bireuen. Data collection techniques included interviews, questionnaires, and tests. Data collection instruments included interview guidelines, item validation sheets, feasibility evaluation forms, and multiple-choice questions with open-ended justifications. The research findings revealed that the material validation assessment obtained an average score of 47.5 ( 46.194), categorized as "very good." Similarly, the feasibility assessment achieved an average score of 72.5 ( 67.188), also falling within the "very good" category. A total of 30 test items from the trial were analyzed in terms of validity, reliability, difficulty level, discrimination index, and distractor effectiveness. Therefore, it can be concluded that the assessment instrument is appropriate for measuring higher-order thinking skills in the topic of acid-base chemistry.

Abstract

This study aims to analyze learning difficulties in relation to students' levels of conceptual understanding—categorized as conceptually understood, misconceptions, and lack of understanding—among 11th-grade science students (Grade XI MIPA) in the Teupah Barat District, specifically concerning the topic of hydrocarbons. A Two-Tier Multiple Choice diagnostic test was employed as the primary instrument. The study utilized a qualitative descriptive method. The population comprised all Grade XI MIPA students from senior high schools in the Teupah Barat District. The sample included 40 students from SMA Negeri 1 Teupah Barat and SMA Negeri 2 Teupah Barat, selected using purposive sampling techniques. Data analysis was conducted using descriptive statistics to process and interpret the students' responses. The results indicate that the Two-Tier Multiple Choice diagnostic test was effective in identifying students' conceptual understanding and in uncovering alternative conceptions through dominant incorrect answer choices that diverged from scientifically accurate concepts.The findings reveal that among the participants, 64% demonstrated conceptual understanding, 23% exhibited misconceptions, and 13% showed a lack of understanding regarding the topic of hydrocarbons. These results highlight the diagnostic tool's utility in pinpointing areas where conceptual reinforcement is necessary to enhance students’ comprehension in chemistry education.
