Pengembangan Petunjuk Praktikum Ipa Untuk Meningkatkan Kemampuan Berpikir Kritis Siswa SMP

Abstract

ABSTRAKPenelitian ini bertujuan mengembangkan petunjuk praktikum IPA yang valid dalam meningkatkan kemampuan berpikir kritis siswa SMP. Indikator kemampuan berpikir kritis siswa mencakup interprestasi, analisis, evaluasi dan inferensi. Penelitian ini merupakan penelitian Research and Development dengan metode Analysis, Design, Development, Implementation and Evaluation (ADDIE). Validasi ahli dilakukan dengan uji expert terkait dengan format, isi/materi, dan bahasa, sedangkan uji coba produk diberikan kepada 35 siswa di salah satu SMP di Jember. Instrumen yang digunakan adalah dokumentasi, lembar validasi, lembar observasi, pretest dan posttest. Hasil tes maupun praktikum menunjukkan adanya peningkatan kemampuan berpikir kritis siswa. Berdasarkan indikator kemampuan berpikir kritis diperoleh nilai ratarata Ngain 0,5 dengan interpretasi sedang. Pengembangan petunjuk praktikum IPA yang dikembangkan dalam kategori layak sehingga cukup efektif dalam meningkatkan kemampuan berpikir kritis siswa.Kata kunci: Petunjuk Praktikum, Ilmu Pengetahuan Alam (IPA), Kemampuan Berpikir Kritis. ABSTRACTThis research aims to develop practical guideline of natural science that can improve critical thinking skills in junior high school students. Indicators of students' critical thinking skills include interpretation, analysis, evaluation and inference. This study was a Research and Development with Analysis method, Design, Development, Implementation and Evaluation (ADDIE). Validation associated with test format, content/material, and language was done by experts, while the implementation was given to 35 students in one of Junior High Schools in Jember. The instruments used are documentation, validation sheets, observation sheets, pretest and posttest. Written and lab test results showed an increase in students' critical thinking skills. Based on indicators of critical thinking skills Ngain value was 0.5, in which it was categorized as moderate. Practical guideline of natural science developed was considered as decent and quite effective in improving students' critical thinking skills.Keywords: Practical guideline, Natural Science, Critical Thinking Skills. PENDAHULUANPembelajaran IPA merupakan suatu proses pembelajaran yang menekankan pada gejala-gejala alam beserta hubungannya antar gejala tersebut, sehingga dalam proses pembelajaran IPA tidak hanya menekankan pada segi kognitif saja, melainkan juga meliputi sikap, proses, produk dan aplikasi yang harus dilakukan secara menyeluruh. Pembelajaran IPA memerlukan suatu keterampilan dalam mengkaitkan antar konsep dan penggalian bukti. IPA sebagian besar dibangun atas dasar rasa ingin tahu, tidak hanya tentang objek yang akan diteliti, tetapi juga merupakan peran sebagai peneliti dan proses transformasi pribadi selama penyelidikan (Mutveia dan Mattssonb, 2014).Proses pembelajaran IPA merupakan suatu kegiatan yang meliputi observasi, membuat hipotesis, merencanakan dan melaksanakan eksperimen, evaluasi data pengukuran, dan sebagainya, sedangkan produk pembelajaran IPA merupakan hasil dari ...

The Effectiveness of Science Module Smp / MTS to Train Critical Thinking Skills

“…Critical thinking skills students include formulating the problem (inference), make a hypothesis (inference), collect data (interpretation), analyze the data (explanation), and make conclusions (evaluation). So also with previous research Wahyuni [7] reported that the IPA developed practical guidance already eligible for use in teaching in junior and can enhance students' critical thinking skills. Beck [8] argues that learning using the experimental method can enhance innovative teaching methods that can be applied by teachers.…”

Development of Mathematics Teaching Materials Based on Realistic Mathematics Education and Literacy in Junior High School

“…Several factors causing the low mathematics literacy of students according to Rusdi [21], are: 1) the teachers' knowledge about mathematical literacy was low, 2) the learning approach still did not related to the material with the context of students' daily lives, 3) the assessment instruments was far from the mathematical literacy, 4) realistic mathematics education approach ever developed by researchers in learning mathematics has not been combined with the concept of literacy yet. According to Whardhani and Rumiati [22] and Masduki, et al [23], the teaching materials used in schools were not enough to support the achievement of students' mathematical literacy yet.…”

“…In this way, teaching materials can support student learning and increase success his. Teaching materials can be defined as breakdowns from a set of materials arranged in a manner systematically both written and unwritten creating an environment or atmosphere allows students to study [25].…”
