Learning physics science is ideally accomplished through the experiments, although the theory of special relativity is challenging to understand. It is difficult because this topic has not occurred in real experience, and no technology has launched at the speed of light. To understand this theory, Virtual Reality (VR) can potentially visualize the actual concept of relativity by presenting an artificial environment to the students. The aim of this research is to develop the virtual reality application as a learning media for special relativity. This Research and Development uses the Lee and Owens Model, which consists of analysis, design, development, implementation, and evaluation. The system development method used is black-box testing. The result of the development of this system is the creation of a VR application to explain the material of relativity. From the results of black-box testing, the test results show that the percentage of application system success is 83%, which indicates that the application is functioning correctly on smartphone usage so that this application can be used on the theory of relativity simulation users using virtual reality devices.
Penelitian ini bertujuan untuk membandingkan kemampuan berpikir kritis matematis siswa yang belajar menggunakan model generative learning dan connecting, organizing, reflecting, extending (CORE). Metode penelitian yang digunakan adalah metode eksperimen semu yang dilakukan pada kelas XI SMA Negeri 12 Jakarta. Teknik pengambilan sampel menggunakan purposive sampling. Kemampuan berpikir kritis matematis siswa diukur dengan tes yang dibuat sesuai indikator keterampilan berpikir kritis matematis pada materi integral sebanyak 5 soal yang telah melalui uji validitas dan reliabilitas. Kedua kelas eksperimen yang dipilih berasal dari populasi yang berdistribusi normal, memiliki varians homogen dan mempunyai kesamaan rata-rata. Berdasarkan hasil penelitian, kelas eksperimen I dengan model generative learning dan kelas eksperimen II dengan model CORE berdistribusi normal dan memiliki varians yang sama. Pengujian hipotesis dilakukan dengan uji-t dan taraf signifikansi Berdasarkan hasil perhitungan, diperoleh dan sehingga , maka ditolak. Oleh karena itu, dapat disimpulkan bahwa kemampuan berpikir kritis matematis siswa yang belajar dengan model generative learning lebih tinggi daripada model CORE.
Kesalahan klasik yang selalu muncul dalam memahami mata pelajaran biologi adalah karena banyak peserta didik menganggap biologi sebagai pelajaran yang membosankan.Selain itu, menurut hasil wawancara dengan salah satu guru IPA, menyatakan bahwa pada cabang ilmu biologi materi struktur dan fungsi jaringan tumbuhan adalah salah satu materi yang paling sulit dipahami oleh siswa. Hal ini dikarenakan mempelajari materi ini secara detail memerlukan alat bantu (mikroskop) yang hasil pengamatannya belum tentu mudah dipahami oleh siswa. Selain itu, selama ini media pembelajaran yang digunakan kurang bervariasi. Berdasarkan pernyataan di atas, maka diperlukan sebuah media pembelajaran yang dapat meningkatkan ketertarikan siswa dan pemahaman siswa dalam mempelajari materi struktur dan fungsi jaringan tumbuhan. Maka penelitian ini bertujuan untuk mengetahui tingkat kelayakan media pembelajaran monopoli terhadap materi struktur dan fungsi jaringan pada tumbuhan. Metode yang digunakan dalam penelitian ini adalah penelitian kuantitatif dengan statistika. Berdasarkan hasil kuisioner terhadap siswa kelas VIII MTs Al-Hasani maka didapatkan nilai rata-rata dari analisis kelayakan adalah 90,27% yang tergolong sangat baik.
Mathematical literacy is one of the components that use mathematical concepts and applies them to an everyday situation. Mathematical literacy helps people to identify and understand the role that mathematics plays in the world, and to make the well-founded judgments and decisions required in life by constructive, engaged, and reflective citizens. By contrast, not everybody acquires sufficiently. This study aims to describe the ability of mathematical literacy especially geometry literacy in terms of student metacognition on conic section material. The problems in this study were: 1) How is the ability of mathematical literacy in terms of student metacognition on conic section material 2) What types of mistakes do students make in solving the problem of cone section and 3) What factors cause students to make mistakes in solving conic section question. This research is a qualitative descriptive study. The subjects in this study were 36 mathematics education students who took courses in Analytical Geometry. The data collected using observation, written test, and interview. Before the researcher conducted the analysis, the researcher examined the validity of the data using validity and reliability tests in order to obtain valid data. Furthermore, the valid data were analysed descriptively through identification, grouping, clarification, explanation and conclusion.
The 21 st century has brought a paradigm change that shifts conventional learning towards technology-based learning. PISA data shows that Indonesia only achieved a score of 382, while TIMSS stated that the percentage of correct answers to the problem of understanding was always higher than the matter of application. This indicates that HOTS students in Indonesia have not yet developed optimally. This investigation intends to create worksheets for students implemented by augmented reality on magnetic field substance. This investigation was development research which used the Dick and Carey method. The product can display 3-Dimensional simulations. According to an investigation, the validation result of the students' worksheets already met the criteria very well in terms of material with a percentage of 95%, in terms of media with a percentage of 86.8% and terms of learning with a percentage of 81%, and product trials by teachers with a percentage of 98%. Meanwhile, trials of students obtained a Ngain result of 0.64 which interpreted an increase in students' high-level thinking skills in the medium level. Therefore, it could be assumed that augmented physics' lab has been suitable for students' higher-order thinking skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
