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

Learning is a process of change for each individual, both in knowledge and attitudes. Every individual after learning will experience changes in their life. When studying at school, teachers only tend to teach students to memorize, read and calculate. Teachers have an important task in the learning process in class to improve students' learning abilities and understanding of the material provided. Based on observations made by the author, at SD N Pajang 3 teachers tend to be monotonous and use the same learning methods every day so that students quickly get bored and have difficulty understanding the material, especially in mathematics lessons. Based on the researcher's observations during the learning process in class 3, especially in mathematics, it was proven that many students did not understand so that based on test scores students got a score of 60. This research uses a qualitative approach which aims to determine the improvement in learning outcomes of class 3 students at SD N Pajang 3 before and after carrying out learning using concrete media. This research was conducted descriptively, namely by providing a pretest and posttest. Based on the results of this research, it was concluded that the use of concrete media had a positive impact and was effectively used in improving students' addition skills.

Abstract

This study aims to find out and describe the types of errors in mathematical proof. This research method is based on literature review. The stages of this literature review are data collection, data reduction, data display, discussion and conclusions. The research results show that of the 6 articles published from 2014-2023 regarding types of errors in mathematical proof, 6 articles were found that were in accordance with the research variables. The novelty of this research is that there is a connection between one article and other articles that discuss the same topic. The conclusion from this data is that there are many mistakes made by students when working on questions that require mathematical proof. The forms of errors made by students include conceptual errors, principle errors, calculation errors, language interpretation errors, and errors when drawing conclusions.

Abstract

There has been little research on literature studies related to using the PhotoMath application as a learning medium to improve students' computing abilities. The aim of this research is to analyze whether the PhotoMath application can improve students' computing abilities. The previous research article was taken in 2020-2024. The research method used is Systematic Literature Review (SLR) with the PRISMA protocol for all research articles indexed in Google Scholar and Garuda. The search strategy was adjusted to the selection criteria and involved several moderator variables, namely publication year, journal index, and research material. The data obtained is presented in a quantitative descriptive manner. The results of this SLR research show that learning media using the PhotoMath application can improve students' computing abilities if the application is not misused.
