IMPLEMENTASI  MODEL PEMBELAJARAN PROBLEM BASED LEARNING UNTUK MENINGKATKAN HASIL BELAJAR SISWA SMP PADA MATERI SISTEM PERNAPASAN MANUSIA

IMPLEMENTATION OF PROBLEM BASED LEARNING MODELS TO IMPROVE JUNIOR HIGH SCHOOL STUDENTS' LEARNING OUTCOMES ON HUMAN RESPIRATORY SYSTEM MATERIALS

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran, peningkatan hasil belajar, dan respon peserta didik pada pembelajaran berbasis problem based learning. Jenis penelitian yang digunakan adalah Pre-experimental design, dengan rancangan penelitian yang digunakan adalah “one group pretest-posttest design”. Subjek penelitian menggunakan 31 peserta didik kelas VIII-B di UPT SMPN 27 Gresik. Pengumpulan data dilakukan dengan metode tes berupa pretest dan posttest. Intrumen penelitian yang di gunakan meliputi lembar observasi keterlaksanaan, lembar pretest dan posttest, dan lembar angket respon peserta didik. Hasil analisis keterlaksanaan pembelajaran menunjukkan bahwa keterlaksanaan peembelajaran berjalan secara efektif, uji N-Gain telah diperoleh skor dengan kategori tinggi, metode analisis respon peserta didik dilakukan dengan menghitung persentase jawaban “Ya” dan “Tidak” memperoleh skor 4 menunjukkan kategori sangat baik. Berdasarkan out put “Uji paired” bernilai <0,05. Hal tersebut mendukung adanya peningkatan kemampuan hasil belajar peserta didik dengan skor ( = 0,73) tergolong dalam kriteria tinggi. Pada hasil angket respon diperoleh hasil sebesar 99,04% respon positif. Berdasarkan hasil kesimpulan tersebut menunjukkan adanya pengaruh pembelajaran berbasis problem based learning terhadap hasil belajar peserta didik. Dengan demikian, penerapan pembelajaran berbasis problem based learning efektif diterapkan dalam proses pembelajaran.

This study aims to describe the implementation learning, improving learning outcomes, and student responses to problem based learning based learning. The type of research used is the Pre-experimental design, with the research design used is "one group pretest-posttest design". Research subjects use 31 class VIII-B students at UPT SMPN 27 Gresik. Data collection was carried out with the test method in the form of pretest and posttest. Research instruments in use includes implementation observation sheets, pretest and posttest sheets, and student response questionnaire sheets. Results of implementation analysis learning shows that the implementation of learning runs smoothly effective, the N-Gain test has obtained scores with high categories, method of analysisstudent response is done by calculating the percentage of answers "Yes" and "No" gets a score of 4 indicating a very good category. Based out put “Test paired” is <0.05. This supports the increase the ability of students' learning outcomes with a score ( = 0.73) is classified as deep high criteria. In the response questionnaire results obtained a result of 99.04% response positive. Based on the results of these conclusions indicate an influence problem-based learning based learning on participant learning outcomes educate. Thus, the application of problem-based learning is based effective learning is applied in the learning process.
