ABSTRACT
The research aims to improve creativity in thinking and economic learning achievement of first grade students at State Senior High School 1 Bobotsari 2014/2015 academic year through the implementation of two stay two stray cooperative technique by using scientific approach.
The research is classroom behavior research that involves 34 first grade students at State Senior High School 1 Bobotsari 2014/2015 academic year as the subject. The data collection method uses: (a) observation, (b) interview, (c) test, and (d) documentation, data analysis technique using the tecnique of critical analysis and comparative descriptive analysis techniques, while the research procedure involves (1) action plan, (2) action implementation, (3) observation, and (4) reflection.
Based on the research data, it can be concluded that cooperative learning model of two stay two stray method by using scientific approach can improve creativity in thinking and economic learning achievement of first grade students at State Senior High School 1 Bobotsari 2014/2015 academic year. It is proven on the first cycle and second cycle, as the students’ creativity in thinking and learning achievement improves. Prior the implementation of two stay two stray cooperative technique by using scientific approach, classroom’s averagescore stand on 69.88 or 32.36% completeness, whereas students’ creativity in thinking on smooth thought aspect 2.94%, flexible thought 0%, original thought 2.94%, elaboration 2.94% and evaluation 0%. On the first cycle, the classroom’s average score stand on 77 points or 70.59% completeness, while students’ creativity in thinking of smooth thought aspect 47.05%, flexible thought 61.76%, original thought 55.88%, elaboration 52.95% and evaluation 58.82%.
