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.

Abstract

Computational Thinking is a way of thinking that refers to the ability to solve problems using concepts used in computing. Computational thinking is a way of thinking in solving problems that students must develop in the digital era. This research aims to examine the importance of computational thinking in improving students' mathematical problem solving abilities. The type of research used is qualitative research using a literature study approach in the form of books, notes, journals, reports of relevant research results, as well as the results of observations. The results of the analysis show that it is very important for students to have computational thinking in order to improve their mathematical problem solving abilities. Computational thinking involves solving problems using a logical and systematic mindset that involves selecting and using algorithms, data representation, problem decomposition, abstraction, pattern recognition and hypothesis testing. Computational thinking has become an important and essential skill for humans in the 21st century. Educators must advocate the importance of integrating learning with computational thinking concepts into the educational curriculum. Computational thinking has an important role in learning. This can be useful for improving mathematical problem solving abilities. Apart from that, computational thinking can also develop critical, creative and analytical thinking skills in solving complex problems, both in the context of computing and everyday life.

Abstract

This study aims to explain the implementation of computational thinking-based mathematics learning at SMA Negeri 2 Medan. This research is classified as qualitative descriptive research. Data sources used in this study include the learning process, informants from Mathematics teachers of SMA Negeri 2 Medan, teaching modules, and field notes about the learning process based on computational thinking. Data collection techniques include observation, interviews, and document analysis. The results of this study show that computational thinking-based mathematics learning is able to increase teacher creativity in teaching, increase students' thinking to be open to the surrounding environment which is actually closely related to mathematics, and be able to solve problems structurally and computational thinking-based learning gets a good response by students

Abstract

Improving the quality of education in Indonesia can be developed through the implementation of educational reform. One form of educational reform can be carried out by using a learning approach that can help teachers produce experts using the STEM (Science, Technology, Engineering, and Mathematics) approach. Initial findings reveal that only around 47.8% of SMA N 2 Medan students (class This research aims to see the effectiveness of the STEM approach in improving the critical thinking skills of SMA N 2 Medan students. The research method used is an experimental design with Non Equivalent Control Group Design. The research subjects were students of SMA N 2 Medan. The results showed that the sig (2-tailed) Equal variances value was assumed to be 0.000 < 0.05. Therefore, Ho is rejected and Ha is accepted, which means there is a significant difference in critical thinking abilities after students use the Equal variance method. The STEM-PBL approach, compared with the innovative K13 approach. The average critical thinking skills scores of the control class in the pre-test and post-test were 38 and 79.5. The coefficient remains at 0.676 and is significant at 0.000. This means the correlation is positive. Therefore, learning with a STEM approach has proven to be effective in improving the critical thinking skills of SMA N 2 Medan students.

Abstract

The increasingly rapid development of technology and information has enabled transformation in the fields of education and teaching. This is clearly seen in the current curriculum expectations, where one of the expected learning outcomes from elementary school to middle school is that students are expected to have computational thinking skills. For this reason, the aim of this research is to look at students' abilities related to their computational thinking abilities. in solving the problems given. The results of the answers given by students are then analyzed according to the four foundations of computational thinking. This research is descriptive research with a qualitative approach. This research was carried out in the Mathematics Education study program, Universitas Islam Sumatera Utara in the Number Theory course. The sample used was 12 students taking Number Theory courses. The instrument used is a description of 2 questions which are given during the learning process on mathematical induction material. The students' answer sheets were then analyzed to get a picture of students' computational thinking abilities based on the four foundations. The results of this research show that students' computational thinking abilities still need to be improved, such as decomposition abilities which are 41.67% and abstraction abilities which are 58.33%. Overall, students' computational thinking abilities are still in the sufficient ability category.

Abstract

This Classroom Action Research aims to improve students' ability to understand mathematical concepts through the application of the Discovery Learning model supported by snake and ladder games. The research subjects consisted of 29 students. The instruments used in this study include observation sheets, written tests, and documentation. The data obtained was analyzed through several processes, namely data reduction, data presentation, and drawing conclusions. The success of the mathematical concept comprehension test in this study is determined by two criteria, namely the average score of the mathematical concept comprehension test results and the percentage of students who achieve a minimum completeness score. The average score of the mathematical concept comprehension test results in cycle I and cycle II was 67.5 and 78.5 respectively. The percentage of students who completed the first and second cycles were 65.5% and 80.1% respectively. This shows that in the second cycle, the average score of the mathematical concept comprehension test results and the percentage of students who completed it have met the set criteria. Thus, the application of the Discovery Learning model supported by the snake and ladder game has proven successful in an effort to improve the ability to understand mathematical concepts of students in grades IX-4 of UPT SMP Negeri 8 Medan
