Abstract

The importance of developing critical thinking skills (CTS) is claimed as a major education purpose.  Recently, enhanced learning has been conducted to promote students' CTS through study on certain topics (specific domains). Based on the numerous studies on CTS, there is a need for an assessment instrument to test students' CTS.  This research aims to develop an instrument of CTC on mechanical wave topics for senior high school students. The instrument consists of seven essay items and one forced-choice item, tested to 45 students of class XI high school in Malang. The validity test obtained an excellent Cronbach alpha coefficient of ? = 0.717. There was also an inter-rater test for the scoring guideline reliability using the intraclass correlation coefficient (ICC) with high reliability results (? = 0.909). The results of this study indicate that the instrument is qualified to be used to measure students' CTS on mechanical wave topics.

Abstract

Abstract: Critical thinking skills as an important skill in the 21st century is a major goal of science education. Therefore the researchers develop various learning strategies to enhance and develop students' critical thinking skills. They develop learning materials that integrated with ability to think critically. However, the strategy makes students less understand to the concept of the material. Learning strategy as bounded inquiry lab model can improve both critical thinking skill and students' comprehension of the material. This study aims to determine effectiveness of bounded inquiry lab to critical thinking skills in high school students. This study focuses on hydrostatic pressure, Pascal's law, and Archimedes’ law. Mixed methods of embedded model design were used during the study. A total of 30 students in major natural science program undergo pre test, followed by learning using bounded inquiry lab, doing post test and then interview. The results showed that students' critical thinking skills on hydrostatic pressure, Pascal's law, and Archimedes’ law increased from an average of 20.00 in pretest to 80.67 in post test. In addition, students said that they can improve their understand concepts of matter, determine the variables, how to create and test hypotheses through scientific work, and make good conclusion through classroom learning. So, bounded inquiry lab should be used as an alternative learning to enhance critical thinking skills in static fluids. Abstrak: Keterampilan berpikir kritis sebagai keterampilan penting di abad 21 merupakan tujuan utama pendidikan sains. Hal tersebut membuat para peneliti mengembangkan berbagai strategi pembelajaran untuk mengembangkan keterampilan berpikir kritis siswa. Sebagian besar peneliti mengembangkan keterampilan berpikir kritis yang terintegrasi dengan materi pembelajaran. Namun, strategi tersebut membuat siswa kurang memahami konsep dari materi. Strategi pembelajaran berupa model bounded inquiry lab merupakan salah satu model yang dapat meningkatkan keterampilan berpikir kritis sekaligus meningkatkan pemahaman siswa pada materi. Penelitian ini bertujuan mengetahui efektivitas bounded inquiry lab terhadap keterampilan berpikir kritis siswa SMA. Penelitian ini berfokus pada materi tekanan hidrostatis, hukum Pascal, dan hukum Archimedes. Mixed methods desain embedded model digunakan selama penelitian. Sebanyak 30 siswa kelas XI IPA SMA menjalani pre test, dilanjutkan dengan pembelajaran menggunakan bounded inquiry lab, mengerjakan soal post test kemudian wawancara. Hasil penelitian menunjukkan bahwa keterampilan berpikir kritis siswa pada materi tekanan hidrostatis, hukum Pascal, dan hukum Archimedes meningkat dari rata-rata nilai pre test sebesar 20,00 ke nilai post test sebesar 80,67. Di samping itu, menurut siswa, pembelajaran di kelas membuat mereka lebih memahami konsep materi, menentukan variabel, cara membuat dan menguji hipotesis melalui kerja ilmiah, serta membuat kesimpulan dengan baik. Berdasarkan hasil penelitian, bounded inquiry lab dapat digunakan sebagai salah satu alternatif strategi pembelajaran untuk meningkatkan keterampilan berpikir kritis siswa pada materi fluida statis.
