Abstract

Alternative conceptions or misconceptions is believed as the main barrier for most students who learn chemistry. Students who hold alternative conceptions will struggle to understand the advanced concepts. Therefore, identifying those alternative conceptions is important. In this study a diagnostic test was designed and developed to identify students’ alternative conceptions about intermolecular forces (IMFs). The diagnostic test developed in this study consist of 19 multiple choice questions with open reason. The test was administered to 88 university students who learn chemistry. Data collected were analyzed using SPSS. The validity and the reliability of the test were 0.526 and 0.878 respectively. The result indicates that the test is valid and reliable. The mean difficulty value and discriminatory index are 0.623 and 0.45 respectively. The findings of the item analysis showed that the test is in moderate difficulty and the discriminatory of the test is in good category. Meanwhile, the average distractor effectivity for the diagnostic test is 3 options (out of 4 options), which means the distractors are in good category and well function. Those findings indicate that the two-tier diagnostics test could be used to identify students’ alternative conceptions and understanding about IMFs.

Abstract

The misconception is the most topic in chemistry learning that is important to analyze. There are many advantages for lecturers and students to know about misconceptions. This research aims to describe misconceptions in general chemistry courses, especially intermolecular forces (IMFs) topic. The two-tier multiple-choice tests have played an important role in helping researchers determine students’ level of understanding and in identifying specific misconceptions. The project used a convenience sample of 88 students (76 female and 12 male) chemistry education program that studied IMFs as participants. Misconception knew from the test’s second tier, which is the student’s reason for the answer. Surprisingly, 29 misconceptions were acquired from the test about IMFs concepts.  This needs to be a special concern for lecturers of basic chemistry courses in order to evaluate the learning process that has been carried out. Students misconceptions in basic chemistry courses will have an impact on organic chemistry courses because the concept of intermolecular forces will be studied in depth in organic chemistry courses. The success of students in organic chemistry courses is highly dependent on the initial knowledge of students, especially in basic chemistry courses
