Abstract

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran berbasis problem solving yang layak dan efektif digunakan dalam proses pembelajaran IPA materi perubahan lingkungan dan pengaruhnya terhadap hasil belajar kogitif peserta didik kelas IV sekolah dasar. Penelitian pengembangan ini mengacu langkah yang dikembangkan oleh Borg & Gall. Perangkat pembelajaran yang dikembangkan divalidasi oleh ahli pembelajaran dan ahli evaluasi sebelum diujicobakan. Kemudian penerapannya dalam proses pembelajaran dinilai oleh guru kelas dan peserta didik. Perangkat pembelajaran berbasis problem solving berupa silabus, Rencana Pelaksanaan Pembelajaran (RPP), Lembar Kerja Siswa (LKS), dan Tes Hasil Belajar (THB) yang layak digunakan pada proses pembelajaran mendapatkan penilaian dengan kategori sangat baik dari ahli kecuali THB dengan kategori penilaian baik. Keefektifan perangkat pembelajaran dapat dilihat pada ketercapaian hasil belajar peserta didik yang pembelajarannya menggunakan perangkat pembelajaran berbasis problem solving lebih tinggi daripada peserta didik yang pembelajarannya dilakukan secara konvensional. Hal ini karena pemilihan materi “perubahan lingkungan dan pengaruhnya” dalam penyusunan perangkat pembelajaran menyajikan beragam permasalahan sehingga proses pemecahan masalah menarik bagi peserta didik.Kata kunci: pengembangan perangkat pembelajaran, problem solving, pembelajaran IPA DEVELOPING LEARNING DEVICES BASED ON PROBLEM SOLVING ON SCIENCE SUBJECT TOWARD COGNITIVE ACHIEVEMENT IN ELEMENTARY SCHOOLAbstractThe aims of this research are to produce learning devices based on problem solving that are appropriate and effective used in environmental changing and it effects materials in science towards cognitive learning result of the elementary school students grade 4. This developmental research refers to the steps developed by Borg & Gall. The learning devices that developed, were validated by a learning and evaluation expert before it was tested. Then, the implantation in learning process were evaluated by the teachers and the students. The learning devices based on problem solving include syllabus, lesson plans, student worksheets, learning achievement tests, that are appropriate on learning process because it gets very good category from the expert except the learning achievement test that belongs to good category. The effectiveness of the learning devices can be seen on the student’s result that used learning devices based on problem solving is higher than the students who use the conventional learning it is because the material selection on environmental changing and its effects in arranging the learning devices serves various problems, so the problem solving process interest the students.Keywords:development of learning device, problem solving, and science learning

Abstract

The low learning outcomes of students in Natural Science is the main problem in this study. It is due to the ineffective science learning system in its application so that students are less interested in learning science. This study aimed to determine the effectiveness of using guided science discovery learning in improving learning outcomes of fifth grade elementary school students. The method used in this research is pre-experimental one group pretest-posttest design. The sampling technique used nonprobability sampling model, namely purposive sampling. The data analysis used was the effectiveness test using the paired sample t-test assisted by SPSS 21 through comparing the sig (2-tailed) value with an alpha value of 5%. The number of samples used was 28 students. The research instrument was a multiple-choice test and a questionnaire. The results showed that the mean pretest value was 59.29 and the posttest value was 0.082; the pretest significance was 0.126, the significance for the posttest was 0,082; the significance of guided science discovery learning was 0,200, each of which has a significance value of 0,000 <0, 05. It means that there is a significant difference, while the t value is 12,515. It means that the pretest score is smaller than the posttest, which is 12,515, so it can be stated that guided science discovery learning is effective in improving student learning outcomes. Thus, it can be concluded that there is a positive and significant effect of guided science discovery on learning outcomes of fifth grade elementary school students.
