Abstract

Abstract. This study aims at describing (1) students’ level comprehension; (2) factors causing difficulties to 3D comprehend molecule representation and its interconversion on chirality. Data was collected using multiplechoice test consisting of eight questions. The participants were required to give answers along with their reasoning. The test was developed based on the indicators of concept comprehension. The study was conducted to 161 college students enrolled in stereochemistry topic in the odd semester (2014/2015) from two LPTK (teacher training institutes) in Bandar Lampung and Gorontalo, and one public university in Bandung. The result indicates that college students' level of comprehension towards 3D molecule representations and its interconversion was 5% on high level, 22 % on the moderate level, and 73 % on the low level. The dominant factors identified as the cause of difficulties to comprehend 3D molecule representation and its interconversion were (i) the lack of spatial awareness, (ii) violation of absolute configuration determination rules, (iii) imprecise placement of observers, (iv) the lack of rotation operation, and (v) the lack of understanding of correlation between the representations. This study recommends that learning show more rigorous spatial awareness training tasks accompanied using dynamic visualization media of molecules associated. Also students learned using static molecular models can help them overcome their difficulties encountered.
