UPAYA MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH DAN KEMAMPUAN BERPIKIR KREATIF MATEMATIKA DENGAN MENGGUNAKAN PENDEKATAN OPEN ENDED PADA SISWA DI KELAS VIII SMP MUHAMMADIYAH 02 MEDAN TAHUN AJARAN 2015/2016

Abstract

Efforts to Improve Problem Solving Ability and Creative Thinking
Skills Mathematical Approach Using Open Ended At Students In Class
VIII SMP Muhammadiyah 02 Terrain Academic Year 2015/2016.
Thesis, Department of Mathematics Education and Teaching Faculty
Tarbiyah State Islamic University of North Sumatra, Medan, 2016. This
study aims to determine: 1) The ability of solving students 'problems
before using the approach of open-ended, 2) Ability solving students'
problems after using the approach of open-ended, 3) Ability to think
creatively math student before using the approach of open-ended, 4)
Ability to think creative math students after using the open-ended
approach, 5) Description of the application process is open-ended
approach, 6) Description of student response during the learning
process with the adoption of open-ended approach. This research is a
classroom action research (PTK) is conducted in two cycles, each cycle
consisting of two meetings. The instrument used to collect the data
consists of the initial capability test, post test I, II post test, interview
and observation sheet. The research findings inform, before the
adoption of the open-ended approach to the problem solving and
creative thinking abilities mathematics of the 32 students who took the
tests beginning no complete student in achieving the KKM. Once
applied the open-ended approach to the students in class VIII-B proven
effective and can improve the ability of students. This can be seen in the
first cycle was obtained by 15 students who completed reaching the
KKM, while 17 students have not fully reached the KKM. In the second
cycle test was obtained by 28 students and 4 students said to complete
the unfinished reached the KKM. In the open-ended approach to the
implementation of the first cycle teachers have difficulties in time
management is less effective and efficient. But in the second cycle is
done then the teachers are increasingly skilled at managing time by
utilizing pembelajan media actively. And the result of students
achieving an average value classical. The response of students in the process of implementing an open-ended approach to increased activity
where students in the first cycle by either category. Then in the second
cycle students learning activities increased with very good category. It
can be seen that the students responded well and active in learning
mathematics with application of the open-ended approach.
