Abstract

The spatial ability affects the understanding of the material that is a three-dimensional representation. This study aims to calculate the contribution of spatial ability to understanding symmetry. The research method used is correlational quantitative, with Sixty-two Chemistry Department students in the fifth semester taking chemical bonding courses. Tests of spatial intelligence and familiarity with molecular symmetry were used to compile information. The Pearson product-moment test was used to analyse the data. The results showed that students' spatial ability in the high category had a positive relationship with students' success in understanding molecular symmetry.

Abstract

Most chemical concepts are abstract, hierarchical, and constructed from basic to complex concepts. Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry have hierarchical idea. This study attempted to characterize and determine the relationship between students’ knowledge of Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry of the 1st, 2nd, and 3rd-year chemistry students at a public university. This study involved 88 students in total selected using proportionate stratified random sampling. The instrument was a relevant short-answer question on the three topics. The data were measured using nonparametric statistics, especially the Kruskal-Wallis difference and Spearman Rank correlation tests.  This study’s results show differences in understanding of Lewis structure, molecular geometry, and symmetry between the 1st, 2nd, and 3rd-years students. The 3rd-year students always performed better than the 1st and 2nd-year students for all topics. The test result confirms a positive and strong relationship between students’ understanding of Lewis structure and molecular geometry for the three groups of students with ρ values of 0.979, 0.979, and 0.966 (< 0.01) for 1st, 2nd, and 3rd-year students, respectively.

Abstract

Objective: The study aims to analyzing the Ability to Solve Symbolic Level Chemistry Problems on Buffer Solution Material at SMA Negeri 1 Mawasangka Tengah aims to determine the ability to solve symbolic level chemistry problems and responses of MIPA XI class students to Three Tier Multiple Choice questions on buffer solution material. Method: This research method using descriptive qualitative method. The entire population in this study was used as a sample, namely all students of class XI MIPA, totaling 60 students. Data collection was carried out using a Three Tier Multiple Choice diagnostic test and a student response questionnaire. Finding: The results showed that the ability to solve symbolic level chemistry problems on buffer solution material was still low, with an average percentage of understanding the concept of 9.77%, misconceptions of 57.75%, and not understanding the concept of 32.48%. Students' responses to the use of three-tier multiple-choice questions were positive, with a percentage of 74.30%; students gave good responses to the three-tier test, so this form of test is categorized as good to identify the level of student understanding in solving symbolic level chemistry problems on buffer solution material. Concusion: From the results of the analysis, it can be concluded that the diagnostic three-tier test is one of the good test forms to find out about problem-solving skills in the form of problems. Keywords: chemistry problem solving ability, symbolic, three tier multiple choiceDOI: http://dx.doi.org/10.23960/jpp.v13.i1.202310
