摘要：This study aimed at finding out the effect of Treffinger creative learning model
with RME principles on creative thinking skills by controlling numerical ability.
This study was conducted to the fifth grade students of elementary schools in
Manggarai regency using post-test only control group design of experiment. This
study involved 101 fifth grade students as sample who were selected by using
random sampling technique. The instruments were numeric ability test and creative
thinking skill test. Data were analyzed by using ANCOVA aided by SPSS 23.0
program. The results showed that 1) the creative thinking skill of the students who
learned mathematics Treffinger creative learning model with RME principles was
higher than those who learned mathematics through conventional model, 2) the
creative thinking skill of the students who learned through Treffinger creative
learning model with RME principles was higher than those who learned through
conventional learning model, after controlling numeric ability, 3) numeric ability
gives a 33,2% contribution to the students’ creative thinking skill. These findings
show that Treffinger creative learning model with RME principles has a significant
effect on the students’ creative thinking skill. Mathematics teachers are suggested
to employ this model in developing students’ creative thinking skill.
