PENGARUH PENDEKATAN PEMBELAJARAN DAN LOCUS OF CONTROL TERHADAP KEMAMPUAN PENALARAN MATEMATIKA SISWA SMP
Abstract: This study aims to
determine: (1) whether there are differences in mathematical reasoning ability
of students who were given open-ended learning approach with students who are
given conventional teaching approaches. (2) whether students' mathematical reasoning
abilities that have an internal locus of control is better than students who
have external locus of control on the open-ended approach to learning and
conventional learning approach. (3) whether there is an interaction between
learning approach with the locus of control that students have in influencing
students' mathematical reasoning. The population of this study are all SMP
Negeri Lhokseumawe are selected by purposive sampling SMP 11 and SMP 13 as the
sample with the students as many as 135 people. This research used
quasi-experimental 2x2 factorial design. The instrument used is the
mathematical reasoning ability and locus of control with the reliability of
each of 0.923 and 0.611. Based on the analysis of variance (ANOVA) found that:
(1) there are significant differences in reasoning ability on learning approach
with conventional open-ended. (2) there are significant differences in
reasoning abilities in both types of locus of control, mathematical reasoning
abilities of students who have internal locus of control is better than an
external locus control. (3) there is no interaction between learning approach
with the locus of control 's students. Based on the results of the study,
researchers suggested that open-ended learning approach can be used as an
alternative capable of learning to develop students' mathematical reasoning and
is also able to gradually change an external locus of control students have an
internal direction.
