Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan bar model terhadap kemampuan literasi matematika khususnya pada materi aljabar. Penelitian ini adalah penelitian kuantitatif. Metode penelitian yang digunakan adalah metode eksperimen dengan teknik pengambilan sampel menggunakan cluster sampling. Subjek dalam penelitian ini adalah 36 siswa pada kelas eksperimen dan kontrol. Kedua kelas yang dipilih berasal dari populasi yang berdistribusi normal, memiliki varians homogen dan mempunyai kesamaan rata-rata. Pengumpulan data menggunakan tes tertulis yang dibuat sesuai indikator keterampilan literasi matematika pada materi aljabar sebanyak 5 soal yang telah melalui uji validitas dan reliabilitas. Berdasarkan hasil penelitian, kelas eksperimen dan kelas kontrol berdistribusi normal dan memiliki varians yang sama. Pengujian hipotesis dilakukan dengan uji-t dan taraf signifikansi  Berdasarkan hasil post-test, diperoleh  dan  sehingga , maka  ditolak. Oleh karena itu, dapat disimpulkan bahwa penggunaan bar model lebih efektif daripada model konvensional untuk mengembangkan kemampuan literasi matematika. AbstractThis study discusses the efectiveness of bar modeling on specific mathematical literacy abilities in algebraic material. This research is quantitative research. The research method used is a research method with a sampling technique using cluster sampling. The subjects in this study were 36 students in the experimental and control class. The second class chosen is normally distributed, has homogeneous variants and has the same average ability. Collecting data using written tests that are made in accordance with mathematical literacy skills in algebraic material as many as 5 questions that have been tested for validity and reliability. Based on the results of the study, the experimental class and the control class were normally distributed and had the same variants. Hypothesis testing is done by t-test and significance level α = 0.05. Based on the results of the calculation, obtained and  so , then  is rejected. Therefore, it can be concluded that the use of bar models is more effective than conventional models for developing mathematical literacy skill.

Abstract

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 learninglebih tinggi daripada model CORE.AbstractThe objective of this study was to compare in mathematical critical thinking skills of students who learn to use the generative learning and CORE models. The research method applied is a quasi-experimental method carried out in class XI SMAN 12 Jakarta. The sampling technique in this study adopted purposive sampling. Students' mathematical critical thinking skills were measured by tests made according to indicators of mathematical critical thinking skills of the integral material as many as 5 questions that have been tested through validity and reliability. The two experimental classes selected came from populations that were normally distributed,  had homogeneous variances and had similarities on average. Based on the results of the study, the experimental class I (generative learning model) and experimental class II (CORE model) were normally distributed and had the same variance. Hypothesis testing is done by using t-test statistics with a significance level  Based on the results of calculations, obtained  dan  therefore , then  is rejected. Therefore, it can be concluded that the mathematical critical thinking skill of students taught with the generative learning model is higher than the students taught using the CORE model.

Abstract

Nowadays, most teenagers don't like Indonesian legends because they are considered as old-fashioned and boring stories. The results of a survey of 124 respondents who are teenagers resulted in 85% of respondents consider the legend is not interesting. Whereas 10% of respondents answered interestingly and 5% answered relatively. This study aims to: (i) develop pop-up books that present Indonesian legends for junior high school students, (ii) provide unique and interesting short stories and (iii) illustrate the comparison of student responses before and after using pop-up books as an alternative learning medium. The research method is research and development (R&D). Based on the results of this study, it was concluded that (1) this research produced a product in the form of a pop-up book entitled "Bhineka Nuswapada", 2) a pop-up book worth using as indicated by the results of the student questionnaire responses of 91.15% with the interpretation of the criteria very good and (3) based on the results of the media effectiveness test, after using the pop-up book media there was an increase in student learning outcomes with an N-Gain value of 0.41 on the medium criteria. Therefore, Bhineka Nuswapada is the best alternative medium for learning legend for students.

Abstract

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.
