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 ThinkingSkills Mathematical Approach Using
Open Ended At Students In ClassVIII 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 thefirst cycle was
obtained by 15 students who completed reaching theKKM, 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 theimplementation 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 activitywhere students in the
first cycle by either category. Then in the secondcycle 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.
