MODEL PEMBELAJARAN LEARNING CYCLE 7E DENGAN PENDEKATAN STEM (SCIENCE, TECHNOLOGY, ENGINEERING, AND MATHEMATICS) UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH DAN KOLABORASI SISWA

Penelitian ini bertujuan untuk mendapatkan karakteristik learning cycle 7e dengan pendekatan STEM dalam pemmbelajaran fisika serta mendapatkan gambaran peningkatan kemampuan pemecahan masalah dan kemampuan kolaborasi siswa melalui model pembelajaran learning cycle 7e dengan pendekatan STEM yang diterapkan. Metode penelitian yang digunakan adalah mixed methods dengan desain Embedded Mixed Methods. Penelitian ini menggunakan populasi salah satu SMA di Kabupaten Kuningan dengan sampel sebanyak 34 orang siswa yang terdiri dari kelas XI MIPA dengan usia rata-rata 17 tahun. Instrumen penelitian yang digunakan yaitu lembar observasi, soal tes kemampuan pemecahan masalah berbentuk uraian, lembar observasi kemampuan kolaborasi, skala sikap kemampuan kolaborasi siswa, serta skala sikap terhadap pembelajaran yang diterapkan. Hasil penelitian menunjukkan peningkatan kemampuan pemecahan masalah siswa menggunakan analisis rasch dan juga menggunakan perhitungan ngain diperoleh nilai sebesar 0,45 termasuk dalam kategori sedang. Juga terdapat peningkatan kemampuan kolaborasi siswa berdasarkan rasch analisis menunjukkan peningkatan yang signifikan. Dengan demikian, model learning cycle 7e dengan pendekatan STEM dapat dijadikan alternatif dalam meningkatkan kemampuan pemecahan masalah dan kemampuan kolaborasi siswa. Kata kunci: Model Learning Cycle 7E, Pendekatan STEM, Kemampuan Pemecahan Masalah, Kemampuan Kolaborasi. This study aims to obtain the characteristics of the 7e learning cycle with the STEM approach in physics learning and to get an overview of improving students' problem solving and collaboration skills through the 7e learning cycle learning model with the applied STEM approach. The research method used is a mixed-methods with design Embedded Mixed Methods. This study uses a population of one high school in Kuningan Regency with a sample of 34 students consisting of class XI MIPA with an average age of 17 years. The research instruments used were observation sheets, problem-solving ability test questions in the form of descriptions, collaboration ability observation sheets, student collaboration skills attitude scales, and attitude scales towards applied learning. The results showed an increase in students' problem-solving skills using Rasch analysis and also using the n-gain calculation, the value of 0.45 was included in the medium category. There is also an increase in students' collaboration abilities based on Rasch analysis showing a significant increase. Therefore the 7e learning cycle model with the STEM approach can be used as an alternative in improving students' problem solving and collaboration skills. Keywords : 7E Learning Cycle Model, STEM Approach, Problem Solving Ability, Collaboration Ability

Pengembangan bahan pengayaan fisika instalasi pengolahan air di Waduk Darma Kabupaten Kuningan

Literasi sains merupakan suatu hal yang sangat penting untuk dikuasai setiap individu. Faktor yang secara langsung mempengaruhi rendahnya kemampuan literasi peserta didik adalah bahan ajar. Namun sayangnya ternyata bahan ajar yang digunakan tidak sesuai dengan kebutuhan untuk menunjang literasi sains peserta didik. Penelitian ini bertujuan untuk menganalisis dampak bahan pengayaan fisika terhadap kemampuan literasi Pengolahan Air pada peserta didik di SMAN 1 Cigugur dan SMAN 1 Kadugede. Metode yang digunakan dalam penelitian ini adalah pengembangan dengan model ADDIE. Populasi dari penelitian ini adalah peserta didik kelas XI MIPA SMAN 1 Kadugede dan kelas XI IPA SMAN 1 Cigugur. Sampel dipilih dengan teknik purposive sampling yaitu kelas XI MIPA 3 SMAN 1 Kadugede dengan jumlah 24 peserta didik, dan XI IPA 3 SMAN 1 Cigugur dengan jumlah 26 peserta didik. Dampak penggunaan bahan pengayaan diperoleh dari nilai N-gain pretest dan posttest peserta didik. Hasil penelitian menunjukkan dampak dari penggunaan bahan pengayaan pada peserta didik berdasarkan index N-Gain diperoleh N-Gain rata-rata di SMAN 1 Kadugede sebesar 0,44 termasuk pada kategori sedang dan N-Gain rata-rata di SMAN 1 Cigugur sebesar 0,41 termasuk pada kategori sedang. Bahan pengayaan dengan demikian dapat dijadikan alternatif untuk menunjang literasi sains peserta didik

Rasch Analysis of Creative Thinking Skill on Optical Instrument (CTSOI) 11th Grade Students Sundanese Tribe: a Case Study

This study aims to determine the creative thinking skills at optic instruments of Sundanese tribe, 11th-grade students. This research is a case study research conducted at a high school in Majalengka district, West Java. Totaling 32 students consisting of 12 male students, namely “Aa”, 20 female students, namely “Teteh”, and 18 Sundanese, the rest are immigrants. The instrument used is the Test for Creative Thinking-optical instrument (TCT-OI) which has existed validated by experts. The data found were investigated with Rasch Analysis Model (RAM). Based on the results of the analysis using the Rasch Analysis, it was found that the creative thinking ability of students stayed static low can be shown by the value of Person reliability which is 0.21 included in the weak category. There are variances in the level of creative thinking skills of students from the Sundanese and non-Sundanese tribes. As a result, it is necessary to develop creative thinking skill on the optical instrument, 11th grade students Sundanese trib

Development of Questionnaire on Students' Perceptions of STEM and Problem-solving (SPSP): a Rasch Modelling Approach

This study aims to prove empirically the validity and reliability of Questionnaire on Students' Perceptions of STEM and Problem-solving (SPSP) in learning physics using Rasch model. The questionnaire was disseminated to 59 (N=59) students class XI MIPA in one of Senior High School in Kuningan Regency. Development of SPSP Questionnaire using procedure of product development model 4-D. The stages that will be used consists of four stages, namely: a) define, b) design, c) development, and disseminate. The data obtained were analyzed by means of the Rasch Model. Based on the result of the study, it shows that the SPSP questionnaire had high reliability that 0.90. So, it can be concluded that SPSP questionnaire is reliable and acceptable. While the item validity analysis shows that there are 8 valid items and 1 item does not match the MNSQ benchmark. Outfit value lies between 0.5 <MNSQ <1.5 and also does not meet the ZSTD Outfit criteria (-2.0 <ZSTD <2, 0). Meanwhile, the students' responses indicate that learning in school has not supported STEM activities and problem solving. So it is necessary to develop learning in schools that can support STEM activities and students' problem solving abilitie
