The purpose of this research was to know the effectiveness of student centre learning (SCL) based experiment method to increase student achievement on topic acid-based solution, type of this research descriptive qualitative, this research was conducted in SMAN 16 Medan the sample that used in this experiment consist of two class which is grade XI IPA1 as experiment class that treated by using student centre learning and Grade of XI IPA 2 as a control class with about student centre learning-based experiment method. Data in this research got from pretest which is given before treated the method and posttest after treated the method. In experimental class, the mean before teaching treatment is = 34, while after giving treatment the mean is increase become 70. In controlled class, the mean before teaching treatment is = 29, while after teaching treatment it changes become 42. The study concludes that the SCL based experiment method is an effective method in the teaching of the acid-based solution to increase student achievement.

The purpose of this research was to analyze student motivation in learning process teach by using Chemsketch. The type of this research is descriptive qualitative research, this research conducted in SMAN 2 Merauke in Papua. Technic that used to get the data using purpose sampling, total population are 28 students in Grade X IPA 2. The data in this research collected using questionnaire that given for student after finish learning process by using software chemsketch on topic hydrocarbon by giving checklist in every item. Based on data analysis, the result only three categorized that got from research, first are 11 student (39.28%) \categorized very high motivation, second are 16 students (57.14%) categorized high motivation , and the third is 1 student (3,5%) categorized medium. From the result showed that the use of chemsketch able to motivate student to learn chemistry especially hydrocarbon topic and for teacher can used as an alternative media for teaching.

This study aimed to determine the representation ability of students in learning chemistry. The ability of representation consists of three levels, namely macroscopic level, submicroscopic level, and symbolic level. This study was a descriptive study. The subjects in this study were 53 XI grade students. The study instrument was in the form of a description test compiled based on indicators of representation ability. The results showed that the average score of studentsâ€™ representation ability at the macroscopic level is 66.94, and is in the good category. The average score of studentsâ€™ representation ability at the submicroscopic level is 47.17, and is in the medium category. The average score of studentsâ€™ representation ability at the symbolic level is 64.30, and is in the good category.

This study aimed to determine the effect of animation media in discovery learning model on the studentsâ€™ representation ability on chemical equilibrium materials. This study was an experimental study using post-test only group design. The study population consisted of 6 classes or 127 students. The sampling technique was done by using purposive random sampling, and 2 classes were chosen consisting of 53 students. Data were collected using a representation ability test which included macroscopic ability, submicroscopic ability, and symbolic ability. By using the inferential analysis of the Mann Whitney test, it was obtained that the significance value for the macroscopic ability was 0.003, the submicroscopic ability was 0,000 and the symbolic ability was 0.041. The significance value is smaller than Î± = 0.05. Referring to that, it can be seen that there is an influence of animation media in discovery learning model on the studentsâ€™ representation ability on chemical equilibrium material.
