THE EFFECT OF AN OPEN-ENDED APPROACH ON STUDENTS’ CREATIVITY IN FRACTIONAL MATERIAL

This research purpused to see whether there was the effect of learning by using open-ended approach on students’ creativity of mathematics aspect. This research was experiment quantitative research. The Population of the research was students of grade III SD Negeri 200117 and for the sample was students at grade III-C. The instrument of collecting data was the test that given twice, that was a test before being treated and a test after being treated. The research method was quasi experiment. The technique of data analysis was using the formula “t” test. Based on the result of hypothesis test, the everage of pretest result was 51.08 and the everage of posttest result was 78.78. Likewise, theresult of test “T” was obtained tcount > ttable = 11.67 > 2.042 with a significant level 5% (0.05) and df = (N-1) = (31-1) = 30. So, we could be concluded that there was a significant effect of an open-ended approach on students’ creativity in fractional material.
