Abstract

This research is based on rapid technological developments, so that science and technology are one of the important foundations in nation building. Science learning is expected to deliver students to fulfill the competences in the 21st Century, to overcome low problem solving skills and to design experimental procedures and experimental device (field study, 2018). The purpose of this study was to determine the effect of STEM-based learning on understanding concepts, critical thinking skills, creative thinking, and collaborative skills on the concept of electroplating. Learning implementation applies the STEM-based approach to the Project-Based Learning (PjBL) learning model, with stages of reflection, research, discovery, application, and communication. The results showed that there was a significant effect on the posttest value of students after using STEM-based learning, with the price of ?Zcount? = 1.648 ? ?Ztable? = 0.16478. Understanding the concept of students has increased with N-gain of 0.43 which is in the medium category. The difference in the results of the pretest with posttest is significant with the price of tcount 3.62> t table 2.015. STEM-based learning influences critical thinking skills of 66.67%, creative thinking (process) 58.33%, creative thinking (product) 55.56%, collaboration skills 94.44%, and communication skills 90.48%. Keywords: PjBL STEM learning, critical thinking skills, creative thinking, collaborative skills, learning outcomes.

Abstract

Conceptual change text is learning material that designed to remedy students’ misconceptions by trigger cognitive conflict and give intelligible, plausible, and fruitful scientific explanation. According to constructivism, students build their own knowledge by themselves by connecting new knowledge with old knowledge that they already own. Conceptual change texts support conceptual change learning based on constructivism theory. This research examines the role of conceptual change text to help students change their conceptions. This research was conducted as quasi experiment with pretest-posttest design to 34 tenth grade students in one of Bandung Barat District public school whose never learn about fundamental laws of chemistry. Written test was used to measure students’ conception. Students’ average score in pretest was 28.8% and 44.1% in posttest. Conceptual change text learning helps students change their initial conceptions into more scientific conceptions. Keywords : fundamental laws of chemistry, conceptual change text, concept mastery

Abstract

learning outcomes of class X.1 students at SMAN 1 Ciwaringin have not reached the standard of competence (KKM) set at school yet. The problem of chemistry learning is that the teacher in the learning process still uses conventional methods with teacher-centered lectures, not using student-centered learning models yet, so that students' thinking skills are less optimized to be more critical and more effective through application of college ball type active learning. This Classroom Action Research design consists of two cycles, each cycle consisting of four stages, namely planning, observing and reflecting. Research subjects are teachers and students of class X.1. Data collection techniques use observation and test results. The results of the study showed that before the study of chemistry learning outcomes, students obtained an average value of 68.10 with classical completeness of 37.43%. After conducting research in the first cycle obtained an average value of 78.20 with classical completeness of 83.40. In the second cycle the average value and completeness of classical learning has reached the indicator of minimum completeness success, namely the value of completeness learning ? 76 with classical completeness 83%. The conclusion of this study is the application of college ball type active learning can improve student activity, teacher performance and student learning outcomes in teaching and learning process.

Abstract

Reciprocal teaching merupakan strategi pembelajaran yang memusatkan perhatian kepada proses berpikir anak. Proses pembelajaran dari pendakatan reciprocal teaching, seperti: clarifying / mengklarifikasi, Predicting / memprediksi, Questioning / membuat pertanyaan, Summarizing / merangkum. Pada penelitian ini mengkaji bagimana pengaruh pembelajaran reciprocal teaching terhadap hasil belajar peserta didi. Penelitian yang dilakukan merupakan penelitian eksperimen kuasi dengan desain pretes dan postes pada satu kelompok yang menggunakan pembelajaran reciprocal teaching. Sampel yang terlibat dalam penelitian ini berjumlah 34 orang peserta didik kelas X di salah satu SMA Negeri di Kuningan. Tes tertulis dilakukan untuk mengukur penguasaan konsep peserta didik sebelum (pretes) dan sesudah (postes) mengalami proses pembelaaran reciprocal teaching. Pembelajaran menggunakan strategi pembelajaran reciprocal teaching dapat mempengaruhi hasil belajar peserta didik serta mampu memotivasi peserta didik untuk memahami konsep kimia.

Abstract

Penelitian ini didasarkan atas pembelajaran yang masih terpusat pada guru dan juga keberagaman kemampuan siswa di kelas merupakan tantangan untuk menciptakan proses pembelajaran yang efektif untuk setiap siswa. Oleh karena itu guru harus memiliki kemampuan didaktis yang mampu mengantisipasi respon siswa dengan beragam kemampuan. Penelitian ini bertujuan untuk mengetrahui hambatan belajar yang dialami oleh siswa pada topik hukum perbandingan tetap. Subyek dalam penelitian ini adalah siswa SMA Laboratorium UPI kelas XI IPA sebanyak 24 orang dan siswa X IPA 1 dan 2 sebanyak 62 orang. Metode penelitian yang digunakan adalah deskriptif kualitatif. Instrumen yang digunakan dalam penelitian ini adalah tes kemampuan responden, lembar observasi, dan pedoman wawancara. Temuan pada penelitian ini adalah secara umum siswa belum paham hokum perbandingan tetap, mereka hanya hapal bunyi dari hokum perbandingan tetap dan masih lemahn dalam hitungan matematis.
