Abstract

The objective of this study are developing the valid Augmented Reality (AR) learning media in Android platform for three dimensional curved surface  and getting the students responses. This study was using the type of Research and Development (R&D) with the ADDIE model ( Analysis, Design, Development, Implementation, Evaluation). The data collection technique was using the questionnaire, which used to validating the media and getting the students responses. The validation was obtained from lecturer in State University of Medan  as the material experts and media experts. The media have been implement to the students in the 3rd grade of SMP Negeri 35 Medan. The result of this study show that the AR learning media is the very valid learning media in accordance to the total score percentage of material experts (81,25%) and media experts (82,14%). The students was responsing that the AR learning media in excelent category in accordance to the total score percentage of students responses (85,88%). Therefore, based on the validation, the validity of the android-based augmented reality learning media for three dimensional curved surface has been tested

Abstract

Pancasila is the entity and identity of the Indonesian nation. For this reason, Pancasila is the basis and foundation of education in Indonesia. Pancasila has unique values ​​contained in it and can be realized in 21st century learning. This research was conducted to find out how Pancasila values ​​are realized in 21st century learning both inside and outside the classroom. This research is qualitative research with observation methods carried out at SMAN 14 Medan. The results of this research show that SMAN 14 Medan has realized Pancasila values ​​in 21st century learning. These values ​​are the value of religiosity, the value of honesty, the value of responsibility, the value of civility, the value of justice, the value of unity, the value of consensus deliberation, the value of democracy, the value of social justice and the value of mutual cooperation. The realization of Pancasila values ​​is carried out side by side and mutually supports 21st century learning, namely the development of 4C skills.

Abstract

This study aims to find out how students apply the four foundations of computational thinking in solving mathematics problems and whether students have applied computational thinking in solving mathematics problems. The research was conducted using an analytical approach to examine the results of solving mathematics problems. This approach involves collecting data from various sources, including tests, quizzes, or assignments given to research subjects. The collected data was then analyzed comprehensively to identify the use of four foundations of computational thinking in the process of solving mathematical problems. The results of this research are that students apply the four foundations of computational thinking. Decomposition by writing down what is known and looking for what is needed in the problem. Pattern recognition by understanding what is known and asking then using the right formula. Abstraction by writing formulas, ignoring what is not needed in the problem, and simplifying the answer. Algorithm by entering the required values into the formula then calculating them and solving the problem in the correct sequence of steps. Even though students make mistakes when solving mathematics problems, students can apply the four foundations of computational thinking.
