Abstract
The misconception is a mistake in building conceptions based on accepted theory. Undetected misconceptions can prevent students from understanding concepts at the next level. This study aimed to determine the profile of misconceptions experienced by the participants did at level particulate on acid-base material. Students misconceptions are detected by using the three-tier multiple-choice test and interview questions. This type of research is quantitative descriptive with the subjects trying 230 students of science class grade 2. The study was conducted at SMA Pangudi Luhur Don Bosko Semarang, SMA Negeri 1 Ungaran, and SMA Negeri 2 Demak. The results showed the general misconception in the acid-base material is 40% in SMA Negeri 1 Ungaran, 43% in SMA Negeri 2 Demak, and 43% in SMA Pangudi Luhur Don Bosko Semarang. Positive misconceptions in SMA Negeri 1 Ungaran, SMA Negeri 2 Demak, and SMA Pangudi Luhur Don Bosko Semarang are respectively 10%, 8%, and 12%. Negative misconceptions in SMA Negeri 1 Ungaran, SMA Negeri 2 Demak, and SMA Pangudi Luhur Don Bosko Semarang are respectively 9%, 2%, and 6%. High-level misconceptions in SMA Negeri 1 Ungaran, SMA Negeri 2 Demak, and SMA Pangudi Luhur Don Bosko Semarang are respectively 24%, 30%, and 25%. The misconception profile of students at the particulate level in Acid-base learning in SMA Negeri 1 Ungaran, SMA Negeri 2 Demak, and SMA Pangudi Luhur Don Bosko Semarang were 39%, 48%, and 56% respectively. Based on the results of the analysis of research data it can be concluded that there are misconceptions about acid-base strength, the concept of pH, and the calculation of pH. This is because the item uses levels of evaluation and analysis at the particulate level.
