ISNAINI CAHYANTO: Pengembangan Lembar Kerja Peserta Didik (LKPD) Model Problem-Based Learning (PBL) untuk Meningkatkan Keterampilan Proses IPA dan Sikap Peduli Lingkungan Peserta Didik Sekolah Menengah Pertama. Tesis. Yogyakarta: Program Pascasarjana, Universitas Negeri Yogyakarta, 2015.
Penelitian ini bertujuan untuk (1) mendeskripsikan kelayakan LKPD Model PBL berdasarkan hasil penilaian dosen ahli dan pendidik IPA, dan (2) mengukur keefektifan LKPD model PBL dalam meningkatkan keterampilan proses IPA dan sikap peduli lingkungan peserta didik SMP.
Penelitian ini menggunakan adaptasi model pengembangan Borg dan Gall. Populasi penelitian adalah peserta didik kelas VII SMPN 3 Leuwiliang yang terbagi dalam enam kelas. Teknik sampling yang digunakan adalah simple random sampling. Kelas VII 4 sebagai kelas eksperimen dan kelas VII 5 sebagai kelas kontrol. Pengambilan data menggunakan tes tertulis (pretest dan posttest), lembar observasi, lembar analisis LKPD, dan angket. Validasi produk dilakukan oleh satu ahli materi, satu ahli media, 11 pendidik IPA, dan sembilan peserta didik. Analisis data menggunakan uji statistik multivariat dengan taraf signifikansi 5% untuk menganalisis perbedaan rata-rata gain skor keterampilan proses IPA dan sikap peduli lingkungan peserta didik antara kelas eksperimen dan kontrol.
Hasil penelitian ini berupa LKPD model PBL pada materi pencemaran lingkungan yang dinilai sangat baik. Penilaian kualitas didasarkan atas aspek materi, didaktik, konstruksi, dan teknis oleh ahli materi, ahli media, dan pendidik IPA. Keterampilan proses IPA yang meliputi keterampilan observasi, klasifikasi, merumuskan masalah, investigasi, menyimpulkan, dan mengkomunikasikan. Sikap peduli lingkungan terdiri dari komponen afektif, kognitif, dan konasi tentang penghematan energi, kebersihan, keindahan, kebiasaaan hidup sehat, dan pelestarian lingkungan sekitar. Hasil validasi dan uji coba produk menunjukkan bahwa (1) LKPD model PBL layak digunakan dalam pembelajaran IPA, dan (2) efektif dalam meningkatkan keterampilan proses IPA dan sikap peduli lingkungan peserta didik SMP.
ABSTRACT
Isnaini Cahyanto: Developing a Student Worksheet with Problem-Based Learning (PBL) Model for Improving the Science Process Skills and Environmental Care Attitude of Junior High School Students.Thesis. Yogyakarta: Graduate School, Yogyakarta State University, 2015.
This study aims (1) to explain the validity of student worksheet with PBL model, and (2) to reveal the effectiveness of student worksheet with PBL model on improving of science process skills and environment care attitude of junior high school students.
This study uses a model of development adaptation by Borg and Gall. The population were students of class VII SMPN 3 Leuwiliang which are divided into six classes. The sampling technique used was the simple random sampling technique. Class VII 4 was the experimental class and VII 5 the control class. The data collection techniques used paper and pencil tests (pretest and posttest), observation sheets, LKPD analysis sheet, and questionnaire. The validation of the student worksheet was conducted by one subject-matter expert, one media expert, 11 science teachers, and nine junior high school students. The multivariate test with the significance level of 5% was used to analyze the difference of gain score average of science process skills and environmental care attitude between the experimental and control classes.
The result of this study is in the form of a student worksheet with the PBL model on environmental pollution material rated very good. The quality assessment is based on material, didactic, construction, and technical aspects by a subject-matter expert, media expert, and 11 science teachers. The science process skills include the skills in observing, classifying, formulating problems, investigating, concluding, and communicating. The environmental care attitude consists of affective, cognitive, and conative components about energy savings, cleanliness, magnificence, healthy living habits, and environment conservation. The results of the validation and the product testing indicated (1) can be used in the natural science teaching, and (2) can improve students’ the science process skills and environmental care attitude effectively.
