IMPROVING THE LEARNING PROCESS OF POLIFUNCTIONAL COMPOUND TOPIC BY USING JIGSAW COOPERATIVE LEARNING WITH MULTI LEARNING RESOURCES

Organic Chemistry lecture had been held in the classroom meeting and laboratory experiment activity. Many topic were conducted experiment in laboratory activity representatively, such as the alcohol phenols, carboxylic acids, aldehydes ketones as well as other topics. Especially on poly functional compounds are not specific experiment title. Therefore the learning process of polyfunctional compound needs to be improved. The aims of this study to describe the implementation of Jigsaw Cooperative Learning Model in order to enhancing the learning process of Organic Chemistry 2 lecture on polyfunctional compounds topic. It used multi learning resources during the lecture. The study design used one shot case study post-test only design. Methods of data collection used observation, interview, and test methods. Data analysis used descriptive quantitative and qualitative. The study result shown that: The implementation of Jigsaw cooperative learning Model of all components of the average of the 3 observers get a score of 3.49 in good categories; almost all stages of Jigsaw Cooperative learning get score between 3.33 to 4.00 on good and very good category, except the award given syntax obtain an average score of 2.33 in quite well category; learning resources and media usage get score between 3.66 to 4.00 on very good category. The student learning outcome in polyfunctional compound topic with the details value of A- to A 12.9 % ; B- to B+ 77.9%; and C+ 7.4% on mastery learning category; as well as D 1,8% and E 0% on not mastery learning category. The students response about this learning, they interest on the matter 9.1%; learning process 66.7%; and learning resources 21.2%
