Abstract

The purpose of this research is to analyze the effect of Krulick Rudnick Heuristic Strategy based on ethnomathematics on student geometric representation skill (GRS). The research conductes at Junior High School in Jakarta in Academic Year 2018/2019. This research was quasi-experimental method with randomized posttest only control group, which is involve 27 students in experimental class and 25 students in control class that choosen by cluster random sampling technique. The data collecting for GRS used by using the test. The result of research revealed that student’s GRS taught by Krulick Rudnick’s Heuristic strategy based on ethnomathematics is higher than those taught by expository strategy. That skills include visual, symbolic, and verbal indicators. Ethnomatematics involved include culture of bamboo fishtrap (bubu), transplantation of coral reefs, mangrove conservation, processed fish food, fishing activities (manyang), tourist resorts, historic building, and food served in traditional traditions (sea parties). The conclusion of this show that the use of Krulik Rudnick heuristic strategy based on etnomathematics is more effective in enhanching students’ GRS compared with an expository strategy. (η2=0,102).

Abstract

The purpose of this study was to analyze the effect of experiential learning learning models on students' mathematical creative thinking abilities. This research was conducted at MTsN Pagedangan 2014/2015 Academic Year. The research method is quasi-experimental, using a posttest only randomized control group design. The research sample consisted of 56 eighth grade students consisting of 26 experimental class students and 30 control class students obtained by cluster random sampling technique. Data collection on mathematical creative thinking abilities using test instruments. The results revealed that students 'mathematical creative thinking abilities taught with experiential learning models were higher than students' mathematical creative thinking abilities taught with conventional models (t obs = 3,573 and p-value = 0,0005 <0.05). The achievement of students' mathematical creative thinking abilities taught experiential learning models for fluency indicators was 71.15% and for elaboration 53.21% while students who were taught conventional learning on fluency indicators were 57.50% and elaboration 47.22%. The conclusion of this study, experiential learning learning model is more effective in increasing students' mathematical creative thinking abilities compared to conventional models.
