Mathematical connection ability on creative problem solving with ethnomathematics nuance learning model

Abstract

The purpose of this research was to analyze the completeness of mathematical connection ability on Creative Problem Solving with ethnomathematics nuance learning model and its differences on Direct Instruction learning model and to analyze the influence of cultural love attitude toward mathematical connection ability. The materials in this research were rectangle, square, and trapezoid. The population in this research were students of grade VII A, VII B, and VII C at a junior high school in Wonosobo academic year 2017/2018 and selected with cluster random sampling. Particularly, grade VII A was chosen as the experimental class and taught by using Creative Problem Solving with ethnomathematics nuance learning model, while grade VII B as a control class that was taught by using Direct Instruction learning model. The data collection methods used were documentation, written test, and questionnaire. The research instrument used were written test and questionnaire. Then, the data were analyzed by one-sided proportion test, two-point equality test, equality test of two proportions, and regression analysis. Eventually, the results showed that (1) the mathematical connection ability of grade VII students with Creative Problem Solving with ethnomathematics nuance learning model reached the classical completeness; (2) the average of mathematical connection ability by using Creative Problem Solving with ethnomathematics nuance learning model of grade VII better than average of mathematical connection ability using Direct Instruction learning model; (3) the cultural love attitude affected to mathematical connection ability.
