THE DEVELOPMENT OF CHEMISTRY LEARNING MODULE FOR RSBI SENIOR HIGH SCHOOL STUDENTS

The development of chemistry learning module for Rintisan Sekolah Berstandar Internasional (RSBI) Senior High School Students (SHS) is explained. The study is aimed to develop and standardize teaching module to be used as a learning media to increase the students achievement in teaching of chemistry subjects. The research was carried out with the combination of research development and experiment. Research development is conducted to develop and standardize cbemistry learning modules based on competence based curriculum (KTSP), where the experiment is done by teaching SHS students using of a sets of chemistry learning modules compare with conventional teaching with exited textbook that have been used in the target schools. The population of this research were SHS of three RSBI schools at Medan, Tebing Tinggi, and Brastagi. The sample is selected by using purposive sampling to choose two classes in everyschool where one is treated is experimental class and another is as a control class. The selected samples in every class were grouped based on their achievement on chemistry in the first semester to make them in to two categories, the relative high achievement (HA) and relative low achievement (LA). Experimental class is tough by using chemistry learning modules while the control class is tough by using exited textbook. The data were collected by using sets of multiple tests covering all chemistry subjects being taught The students achievement is obtained from their ability to answer the question before teaching (pretest), soon after learning process have been conducted (postest-1), and one month after learning process have been conducted (postest-2). The results showed that the chemistry learning modules have been developed based on KTSP curriculum. The chemistry developed learning modules have been standarized and the performance of the developed chemistry learning modules are categorized to good-very good. The performance of developed chemistry learning modules successively for on the topic of Solubility and Solubility Product (Module I) is categorized as very good (average 3.59), Hydrocarbons (Module 2) is categorized as very good (average 3.64), Thermochemistry is categorized as very good (average 3.48), and Oxidation and Reduction Reactions are categorized as very good (average 3.49). The developed chemistry learning modules have been used as learning media in the teaching of chemistry subjects. The results obtained from pretest showed that the classes (experimental and control class) are relatively equal that make them suitable for teaching treatments activities. The chemistry learning modules have been used as teaching media in the teaching of chemistry subjects, and their affectivities to increase students achievements are also measured. It is known that the developed chemistry learning modules are very effective to increase students achievement on chemistry subjects, where the students achievement on chemistry by using innovated teaching modules are higher than that by using existing text book, and the two method are significantly different There is a positive correlation (r2=0,862) between the students achievements with students motivation on studying chemistry when using developed chemistry leaning modules on the teaching of Solubility and Solubility Product, Hydrocarbons, Thermochemistry, and Oxidation and Reduction Reactions, while in the control class where for the teaching and learning with existing chemistry textbook the correlation is found very low (r2=0.258). It is suggested to use developed chemistry leaning modules as a teaching and learning media on teaching of chemistry subjects because sets of modules be able to motivate the RSBI students to study chemistry independently by themselves and as results will increase their achievements in chemistry subjects.
