Mathematical Reasoning Ability Analysis of Vocational High School Students in The Differentiated Treffinger Learning Model

Abstract

This study aims to investigate, compare, and describe comprehensively the achievement of mathematical reasoning abilities and to find out whether there is an effect of the differentiated treffinger learning model on the mathematical reasoning abilities of class X students of SMK N 1 Demak. The research sample was class X AKL 1 with 36 students as the experimental class and class X AKL 2 with 36 students as the control class. Then as many as 3 experimental class students were analyzed in depth. namely students with high, medium and low responses. This research combine of quantitative and qualitative methods. From the results of the Study it was concluded that the treffinger learning model was differentiated of students' mathematical reasoning abilities in the experimental class better than the control class. The results of the study show the selected research subjects all experienced an increase in their mathematical reasoning abilities with different levels of improvement. This result strengthens the quantitative data above. Respondents in the high response category tend to be able to analyze, generalize, justify and recognize how these solutions can be implemented. Respondents with moderate category responses tend to be able to analyze. Meanwhile, respondents with low category responses tended to be unable to fully interpret the information.
