Abstract

The objectives of this research are to get the successfulness: (1) in the improvement of the learning activeness in the Basic Welding subject matter of the students in Grade X M2 of PGRI Vocational High School 1 of Surakarta through the application of the cooperative learning model of the Jigsaw type; and (2) in the improvement of the learning achievement in the Basic Welding subject matter of the students in Grade X M2 of PGRI Vocational High School 1 of Surakarta through the application of the cooperative learning model of the Jigsaw type. This research used the classroom action research with two cycles. Each cycle consisted of four phases, namely: planning, implementation, observation, and reflection. The subjects of research were the students in Grade X Machinery 2 of the aforementioned school. The sources of research data were observation sheet on the learning activeness and the test of achievement. The data of research were collected through test i.e. written test items non-test i.e. students’ learning activeness observation sheet during the implementation. They were validated through content validity for the data obtained through test and construct validity for the data obtained through non-test. The result of research shows that the application of the cooperative learning model of the Jigsaw type can improve the students’ learning activeness as indicated by the result of observation. Prior to the treatment, only one indicator of learning activeness fulfills the target. Following the treatment with the cooperative learning model of the Jigsaw type, 3 indicators fulfill the target in Cycle I, and all of the indicators fulfill the target in Cycle 2. Furthermore, the students’ average score of learning achievement also improves. In the pre-cycle which uses the lecturing method, the completeness of the learning achievement is 41%. Following the treatment with the cooperative learning model of the Jigsaw type, it becomes 68% in Cycle I and 82% in Cycle II respectively. Thus the application of the cooperative learning model of the Jigsaw typecan improve the learning activeness and achievement in the Basic Welding subject matter of the students in Grade X Machinery 2 of PGRI Vocational High School 1 of Surakarta.
