Abstract

Riset ini bertujuan untuk mendeskripsikan validitas perangkat pembelajaran dengan model kooperatif tipe think-pair-share untuk meningkatkan kemampuan pemecahan masalah fisika peserta didik. Produk yang dikembangkan untuk divalidasi berupa silabus, Rencana Pelaksanaan Pembelajaran (RPP), Lembar Kerja Peserta Didik (LKPD), dan instrumen tes. Jenis riset ini termasuk Research and Development (R&D) model 4D, mencakup beberapa tahap yaitu define, design, develop dan disseminate. Riset ini dibatasi pada tahap develop.Tahap define yaitu langkah awal untuk mendefinisikan masalah. Tahap design yaitu merancang produk pengembangan. Tahap develop yaitu pengembangan produk dilakukan dengan validasi produk oleh validator ahli menggunakan instrumen lembar uji validitas berupa angket. Skor validasi diakumulasikan untuk memperoleh nilai validitas dan reliabilitas. Hasil penyelidikan berdasarkan validasi ahli membuktikan perangkat pembelajaran yang dikembangkan dalam kategori sangat valid dan reliabel. Hal ini menunjukkan perangkat pembelajaran ini layak diterapkan dalam aktivitas belajar dan mengajar untuk meningkatkan kemampuan pemecahan masalah fisika peserta didik. This research describes the validity of learning tools with a think-pair-share cooperative model to improve students' physical problem-solving abilities. The products are developed to be validated in a syllabus, Learning Implementation Plan (RPP), Student Worksheets (LKPD), and test instruments. This type of research includes the Research and Development (R&D) 4D model, consisting of several stages, namely define, design, develop and dissemination. This research is limited to the development stage. The define stage is the first step to defining the problem. The design stage is designing product development. The development stage, namely product development, is carried out with product validation by expert validators using a validity test sheet instrument in a questionnaire. Validation scores are accumulated to obtain validity and reliability scores. The results are based on expert validation to prove the learning tools developed in the very valid and reliable category. This shows that this learning tool is feasible to be applied in teaching and learning activities to improve students' physics problem-solving skills.

Abstract

Abstract: The laboratory has an important role in the learning of physics. Tools and materials are limited often used as an excuse for not doing the lab activities. In addition, the characteristics of the most abstract concepts of physics that cause difficulties in teaching it to students. In this research, we have developed several virtual experiments on the concept of optics. Besides as an alternative to the limited laboratory equipment in LPTK, is also intended as a visualization media of concepts to make it easier to understand by students. The purpose of this study was to examine the effectiveness of a virtual laboratory to increase student’s mastery of optics concepts. This research includes research and development, which is divided into three stages: the preliminary study, model design, and testing models phase. The results showed that the virtual laboratory model effectively used in learning of physics. This is indicated by a higher increase in the mastery of the concept of the experimental class than the control class. The highest increase occurred in the concept of geometrical optics by 79.9%. Keywords:  Virtual Laboratory, Mastery of Concepts, Optics Abstrak: Laboratorium memiliki peranan penting dalam pembelajaran fisika. Alat dan bahan yang terbatas sering dijadikan alasan untuk tidak melakukan kegiatan laboratorium. Selain itu, karakteristik sebagian konsep fisika yang abstrak menimbulkan kesulitan tersendiri dalam mengajarkannya kepada mahasiswa. Dalam penelitian ini, kami telah mengembangkan beberapa eksperimen virtual fisika pada konsep optik. Selain sebagai alternatif terbatasnya peralatan laboratorium di LPTK, juga dimaksudkan sebagai media visualisasi konsep agar lebih mudah dipahami mahasiswa. Tujuan penelitian ini adalah menguji efektivitas laboratorium virtual terhadap peningkatan penguasaan konsep optik mahasiswa. Penelitian ini termasuk penelitian pengembangan, yang dibagi menjadi 3 tahap, yaitu: tahap studi pendahuluan, tahap pengembangan desain, dan tahap pengujian model. Hasil penelitian menunjukkan bahwa model laboratorium virtual efektif digunakan dalam pembelajaran fisika. Hal ini ditunjukkan oleh lebih tingginya peningkatan penguasaan konsep kelas eksperimen dibandingkan kelas kontrol. Peningkatan tertinggi terjadi pada konsep optik geometri sebesar 79.9%. Kata kunci: Laboratorium Virtual, Penguasaan Konsep, Optik

Abstract

This study aims to determine the effect of siscovery learning model on learning outcomes in terms of learning motivation of class XI students in SMA Negeri 1 Batukliang. The study used was a quasi-experimental design with factorial 2x2. The population of this study was all students of class XI MIPA in SMA Negeri 1 Batukliang in academic year 2019/2020. Sampling using a cluster random sampling technique, obtained class XI MIPA 3 as a class experiment and class XI MIPA 2 as a control class. The study applies discovery learning in the experimental class and conventional learning in the control class. Data questionnaire to deteemine student obtained an average 74.00 and an average value of the control class of 54.74. Based on the result of data analysis it can be concluded that: 1) there is the effect of the siscovery learning model on the learning outcomes of students; 2) there is the effect of discovery learning models on students learning motivation; and 3) there is no intraction between discovery learning models and learning motivation towards students physics learning outcomes.
