Abstract

The aim of this study is to determine the interaction between learning factors (CORE and conventional) and the initial mathematical skills factor (KAM) to increase mathematical critical thinking skills (KBKM) of students. The method used in this study was quasi-experimental with the non-equivalent group pretest-post design. The data analysis used was two-way ANAVA test. The results of the study are (1) There is no interaction between learning factors with KAM factors (2) the improvement students’ mathematical critical thinking skills in the CORE (connecting, organizing, reflecting, extending). learning group is higher than the conventional learning group for each KAM group (3) In both learning groups, the improvement of the students’ mathematical critical thinking skills in the upper KAM level is higher than the middle and lower KAM level and the improvement in the middle KAM level is higher than the lower KAM level.

Abstract

This research aims to determine whether the achievement and improvement of mathematical critical thinking abilities of junior high school students who get the experiential learning model is better than those who get conventional learning and to find out which indicators of critical thinking abilities that junior high school students find difficult. This research is a quantitative research with a quasi-experimental research type. The design in this research was the randomized pretest-posttest control group design. The instrument used in this research is a set of tests to describe the mathematical critical thinking ability with a system of two-variable linear equations. The analysis used in this research using the t test, with a one-party hypothesis. Post-test data is used to see the achievement of mathematical critical thinking abilities and N-gain data to see the improvement. The conclusion in this research is the achievement and improvement of mathematical critical thinking abilities of students who receive experiential learning is better than the mathematical critical thinking abilities of students who receive conventional learning. There is aspect that students find difficult, namely the advanced clarification aspect.

Abstract

This research aims to determine the use of project-based learning (PjBL) in the achievement of students' mathematical problem-solving abilities. The variables in this research were PjBL and mathematical problem-solving abilities. The instrument in this research was a description test of mathematical problem-solving abilities, which was analyzed by testing the hypothesis using the Mann Whitney U test. The results showed that the average value of students learning using PjBL was higher than students learning using conventional models. The results of the Mann Whitney test show that learning using PjBL is effective in improving students' mathematical problem-solving abilities.

Abstract

This study explores students' mathematical computational thinking ability in solving the Pythagorean Theorem problem. This research method used a qualitative approach with a phenomenological design. The subjects involved in this study were 12 junior high school students. Six students in grade 7 had not studied the Pythagorean Theorem, and six students in grade 8 were studying the Pythagorean Theorem. This study's results indicate several problems with students' mathematical computational thinking skills in mathematics learning. The first problem is seen from the aspect of abstraction. Students are given problems with the help of digital-based teaching aids. Then the researcher provides procedures containing questions so students can digest the information and follow their intuition to find a solution strategy. Still, students have not decided what information should be stored or ignored. The second problem is seen from the aspect of decomposition. Students have not been able to decompose complex problems into simpler and more manageable ones. Student responses are also still not according to the researchers' predictions. However, with the scaffolding technique, researchers can direct students' intuition or thought processes to focus more on the problem being asked. The third problem is seen from the aspect of generalization. Students have not been able to generalize the problem and have not been able to conclude from the steps that have been taken. These three problems indicate that students cannot recognize and identify patterns well, thereby reducing the efficiency of the mathematical problem-solving process.
