Abstrak / Ringkasan

Given the importance of understanding the concept and the ability in
mathematics reasoning for students learn mathematics, the teachers must determine
the appropriate learning method that can facilitate students understanding the
concepts and the ability reasoning students. One method that can be done is to apply
the PBI model with Open Ended Approach. This reseach was conducted to examine
whether there are differences in the model PBI with Open Ended approach to the
understanding of concepts and the ability in mathematics of reasoning, as well as to
obtain information about students' attitudes toward learning mathematics of PBI
model with Open Ended approach. This research is a quasi-experimental research
with pretest-postes without randomized control groups design. The researsh was
conducted in March until April 2012 with 92 students of the fifth Elementary school
Muhammadiyah, Kampar District, Kampar regency. The instruments used in this
study consisted of testing the understanding of mathematical concepts and reasoning
skills, students' attitudes questionnaires, observation sheet, and interview guides. Data
analysis was performed by t test. The result of this research showed that there was
different of understanding the concept ang the ability in mathematics reasoning
between students that were taught PBI model with Open Ended Approach with who
were taught using the conventional approach. During learning, most students showed
positive attitude towards learning mathematics of PBI model with open ended
approach. This was shown by an increase in student activities that the longer the
better for learning. Based on the findings of the study, the application of the model
PBI with Open Ended approaches can be used as an alternative learning method that
can be applied in an effort to improve the understanding of the concepts and
mathematical reasoning abilities.
