“…Equilibrium Material Using Three Tier Test because most of the material in chemistry lessons is abstract (Viyandari et al, 2012;Yunitasari et al, 2013;Rahayu and Nasrudin, 2014). Chemistry has three levels, namely macroscopic, submicroscopic and symbolic (Brandriet and Bretz, 2014;Naah and Sanger, 2012).…”

“…Chemistry has three levels, namely macroscopic, submicroscopic and symbolic (Brandriet and Bretz, 2014;Naah and Sanger, 2012). According to Rahayu and Nasrudin, (2014) level macroscopic obtained from direct observations. Examples of chemicals that can be seen directly are solids of sugar, salt, iron rust and paper burning.…”

“…An example is a chemical reaction (Kusumaningrum et al, 2018;Setyoko et al, 2017). The symbolic level is a qualitative and quantitative representation in the form of Rahayu and Nasrudin's (2014) formulas, pictures and diagrams.…”

This study aimed to analyze students misconception seen from the relationship between the results of the three tier test and interviews about chemical equilibrium material on the concept of determining the formula Kc, Kp, and the concept of Kc calculation. The research method was descriptive qualitative method. The data collection technique in this study was a test. The research instrument was in the form of three tier test questions consisted of four concepts. The misconceptions were analyzed based on the result of tests given to 30 students were further clarified by interviewing as matching answers. The study was conducted at SMA Negeri 2 Wonosari in Gunungkidul Regency with five interviewed research subjects. The result showed that students experienced misconceptions about the concept of determining the Kc formula by 23.33%, determining the Kp formula by 13,33%, and concept of Kc calculation by 16,67%.

“…Changes in concentration, temperature, volume and pressure to a shift in chemical equilibrium will be difficult to understand if explained only through experimental results that can be observed in the laboratory or if only expressed symbolically by using a reaction equation, because it cannot show the actual dynamics occurring at the submicroscopic level. (Rahayu & Nasrudin, 2014). Therefore, an effort is needed to make these abstract chemical materials more concrete, namely through molecular simulations.…”

The Use of Molecular Simulation-Assisted Discovery Learning in Improving Science Process Skills. Objectives: This study aimed to describe the effectiveness of molecular simulationassisted discovery learning (MSADL) in improving science process skills (SPS) on chemical equilibrium. Methods: This research used the matching-only pretest-postest control group design. The population in this study was all students of XI MIA at MAN 1 Bandar Lampung in 2019/ 2020. The sample was XI MIA 5 and XI MIA 6 obtained by purposive sampling. The data analysis technique used the t-test. Findings: The results showed the average n-gain of students' SPS using MSADL was 0.76 in high criteria, while the average n-gain of students' SPS using conventional learning was 0.54 in moderate criteria. The t-test results showed that the average n-gain of students' SPS using MSADL was higher than students' SPS using conventional learning. Conclusion: It can be concluded that MSADL is effective in improving students' SPS on chemical equilibrium.
