The Diagnosis of Misconception on the Concept of Acid-Base Theory in Prospective Teacher Students Used a Three-Tier Test

Abstract

Several phenomena of misconception have been discovered worldwide. In misconception, students strongly believe in the truth of the answers chosen of the questions given but the answers are wrong. This study aims to identify misconceptions that occur in first year students on the concept of acid-base theory. These students are pre service student in chemistry education. As prospective teachers, these students should be free from misconceptions so that they will not bring misconception to their own students one day. This study used a three tier diagnostic test to diagnose misconception from 125 students (1st and 2nd year) as data resources. The students have been given paper and pencil test consist of 15 questions. Each question consists of three levels, namely the choice of concept answers at the first level. The second level is the reason for the answer to the first level question. The third part is the level of confidence in the answers and reasons. Data analyzed to determine the percentage of misconceptions. The results showed that the first year students experienced misconceptions type 1, 2 and 3 in the low category. There were no students who guessed the answers.
