Abstract: The objective of
this research was to investigate the effect of the learning models on the
learning achievement in mathematics viewed from the reasoning abilities of the
students. The models compared were the cooperative learning model of the
Winplot-assisted STAD, the cooperative learning model of the TAI type, and the
Powerpoint-assisted direct learning model. This research used the quasi
experimental research method with the factorial design of 3 × 3. Its population
was all of the students in grade XI of Senior Secondary Schools of Purworejo in
academic year 2013/2014. The samples of the research were taken by using the
stratified cluster random sampling technique. The size of the sample was 235
students consisted of 80 students in the first experimental class, 77 students
in the second experimental class and 78 students in the control class. The
instruments to gather the data of the research were test of learning
achievement in mathematics and test of mathematical reasoning ability. The data
was analyzed by using the two-way analysis of variance with unbalanced cells.
The conclusions of this research were as follows. (1) The cooperative learning
model of the Winplot-assisted STAD type resulted in a better learning
achievement in mathematics than the cooperative learning model of the TAI type
and the Powerpoint-assisted direct learning model, and the cooperative learning
model of the TAI type resulted in a better learning achievement in mathematics
than the Powerpoint-assisted direct learning model. (2) The students with the
high mathematical reasoning ability had a better learning achievement in
mathematics than those with the moderate and low mathematical reasoning
abilities, and the students with the moderate mathematical reasoning ability
had a better learning achievement in mathematics than those with the low
mathematical reasoning ability. (3) In each mathematical reasoning ability
category, the cooperative learning model of the Winplot-assisted STAD type
resulted in a better learning achievement in mathematics than the cooperative
learning model of the TAI type and the Powerpoint-assisted direct learning
model, and the cooperative learning model of the TAI type resulted in a better
learning achievement in mathematics than the Powerpoint-assisted direct
learning model. (4) In each learning model, the students with the high
mathematical reasoning ability had a better learning achievement in mathematics
than those with the moderate and low mathematical reasoning abilities, and the
students with the moderate mathematical reasoning ability had a better learning
achievement in mathematics than those with the low mathematical reasoning
ability.
