The application of problem based learning (PBL) based on lesson study for learning community (LSLC) to improve students’ creative thinking skill

Penelitian ini bertujuan untuk membandingkan keefektifan pembelajaran matematika berbasis masalah dan pembelajaran penemuan terbimbing ditinjau dari hasil belajar kognitif dan kemampuan berpikir kreatif siswa kelas VIII SMP. Penelitian ini adalah eksperimen semu. Populasi penelitian mencakup seluruh siswa kelas VIII SMP Negeri 5 Yogyakarta tahun pelajaran 2014/2015 yang terdiri atas sembilan kelas. Sampel penelitianmenggunakan kelas VIII.8 dan VIII.. Hasil penelitian menunjukkan bahwa: (1) pembelajaran berbasis masalah efektif ditinjau dari hasil belajar kognitif dan kemampuan berpikir kreatif siswa kelas VIII SMP, (2) pembelajaran penemuan terbimbing efektif ditinjau dari hasil belajar kognitif dan kemampuan berpikir kreatif siswa kelas VIII SMP, dan (3) pembelajaran berbasis masalah lebih efektif daripada pembelajaran penemuan terbimbing ditinjau dari hasil belajar kognitif dan kemampuan berpikir kreatif siswa kelas VIII SMP.Kata Kunci: pembelajaran berbasis masalah, pembelajaran penemuan terbimbing, hasil belajar kognitif, dan kemampuan berpikir kreatif The effectiveness of mathematics problem-based learning and guided discovery learning viewed from the cognitive learning achievement and creative thinking skill AbstractThis research aimed to describe the comparison of the effectiveness of mathematics problem-based learning and guided discovery learning in term of the cognitive learning achievement and creative thinking skill of grade VIII students of junior high school. This research was a quasi-experimental design. The research population included all of grade VIII students of SMP Negeri 5 Yogyakarta in the academic year of 2014/2015 which consisted of nine classes, The sample was classess VIII.8 and VIII.9 randomly selected. The result shows that: (1) mathematics problem-based learning was effective in terms of the cognitive learning achievement and creative thinking skill of grade VIII students of junior high school, (2) mathematics guided discovery learning was effective in terms of the cognitive learning achievement and creative thinking skill of grade VIII students of junior high school, and (3) mathematics problem-based learning was more effective than guided discovery learning in terms of the cognitive learning achievement and creative thinking skill of grade VIII students of junior high school.Keywords: problem-based learning, guided discovery learning, cognitive learning achievement and creative thinking skill

The research aims to (1) produce a student worksheet based on problem based learning that has the potency to improve the 7th grade student's creative thinking skill based on assessment of expert lecturers and science teachers on the content business feasibility component, language and image component, component, and presentation graphics component, (2) know the student response toward the student worksheet based on problem based learning to improve the 7th grade student's creative thinking skills, (3) know the improvement the 7th grade student's creative thinking skills after using the student worksheet based on problem based learning. The design of this research was Research and Development model with 4 d development model which includes define, design, develop, and disseminate. The data analysis technique of appropriateness of the student worksheet and students responses to the student worksheet is quantitative score conversion to qualitative value with five categories, the data analysis technique of the implementation of the problem based learning model and student's creative thinking skill based on observation is a percentage calculation, while the data analysis technique of creative thinking skills pre test and post test is normalized gain score (N-gain score). Based on the results of the research, it can be concluded that (1) a student worksheet based on Problem Based Learning has the potency to improve the 7th grade student's creative thinking skill based on assessment of expert lecturers and science teachers on the content business feasibility component, language and image component, component, and presentation graphics component get score 105.75 of a maximum score of 120 with a value of "A" is categorized as "Very Good", (2) a student worksheet categorized as "Good" with a value of ' B "based on student response with score 66.09 of maximum score of 88, (3) the student's creative thinking skill improves after using a student worksheet based on Problem Based Learning with N-gain score 0.72 categorized as "High".
