Abstract

The purpose of this study was to determine the evaluation of computational thinking ability in understanding the limits of algebraic functions for students majoring in Tadris mathematics at Lhokseumawe State Islamic Institute. The research subjects were 1st semester students, totaling 6 students. Data collection techniques in this study used computational thinking ability tests and interviews, and then the data were analyzed based on computational thinking indicators, namely decomposition, pattern recognition, algorithm thinking, generalization, and abstraction. The results obtained from high computational thinking ability indicators that can be completed perfectly are decomposition, pattern recognition, algorithm thinking, and generalization/abtraction. With moderate computational thinking ability, students have been able to solve problems perfectly for indicators of decomposition and pattern recognition, but for indicators of thinking algorithms and generalizations or abstractions, they are still less precise. Low computational thinking ability has been able to measure decomposition indicators, but for pattern recognition indicators, thinking algorithms are still less precise in solving, while generalization and abstraction indicators do not answer.

Abstract

This research aims to analyze: 1) Validity of the geogebra-assisted learning module developed; 2) Practicality of the geogebra-assisted learning module developed; 3) Effectiveness of the geogebra-assisted learning module developed; 4) Increasing mathematical representation abilities by using the geogebra-assisted learning modules that were developed; 5) Increasing self regulated learning by using the geogebra-assisted learning modules that were developed. This research is development research using the ADDIE development model. Winsgoal adalah slot mahjong gacor dengan fitur scatter hitam winrate kemenangan tinggi.

Abstract

This study examines the background of problem-solving ability and creative attitudes among junior high school students, highlighting their importance in fostering innovation and critical thinking in mathematics education. The purpose of this study is to analyze the influence of problem-solving ability on students' creative attitudes. The classroom process is a learning process that develops local instructional theories for the material of systems of linear equations in two variables. The quantitative study aims to assess the influence of problem-solving ability on students' creative attitudes. This study involved 24 junior high school students in Medan as a sample. The instruments used were a validated problem-solving ability test and a validated creative attitude scale. The results showed that problem-solving ability has a significant positive effect on students' creative attitudes, with a regression coefficient of 0.951, indicating that greater problem-solving ability is associated with stronger creative attitudes. The coefficient of determination (R² = 0.597) indicates that 59.7% of the variation in students' creative attitudes is due to problem-solving ability. In contrast, friendship (40.3%) is due to other factors not examined in this study. These findings suggest that problem-solving ability is a key factor in developing creative attitudes. This study highlights the need to integrate problem-solving ability into the educational curriculum to foster students' creative attitudes. Future research should consider using a larger sample size.
