Abstract

Cognitive flexibility in learning mathematics is necessary to solve problems with various mathematical ideas. In completing assignments, students have different perspectives so as to bring up creative solutions that encourage problem-solving skills. This study aims to determine students' cognitive flexibility level in high school mathematics learning. This quantitative descriptive research aims to describe the contents of a variable in research, without being intended to test a particular hypothesis. The source of data used in this study was class XI students in Pontianak City totaling 173 people. Data is collected by questionnaire with data analysis calculating the percentage index results of questionnaire answers. Based on the results of the questionnaire categorizing the level of cognitive flexibility ability of students in learning mathematics, it was found that there were 39 students with the category "very high" cognitive abilities, 115 students in the "high" category, and 19 students in the "moderate" category. This shows that most high school students in Pontianak City on average have high cognitive flexibility abilities in mathematics learning. This data is supported by the statements of mathematics teachers who describe the ability of students to achieve cognitive flexibility, of course, with maximum effort in teaching. From a teaching point of view, mathematics teachers have certainly considered more innovative teaching techniques in order to grow these abilities.

Abstract

Based on the results of observations made and supported by previous research, it can be seen that the problem-solving ability of students still tends to be low. It can be seen that when students are presented with problem-solving problems, students are resistant and in the end unable to do the problem. Even though mathematical problem solving problems can support students' problem-solving abilities. Problem-solving skills are important as basic mathematical competencies and as provisions for everyday life. The purpose of writing this paper is to analyze the application of the PBL model in developing students' problem-solving skills in mathematics learning in a hybrid context. The subject of this study was a grade VII student at a private school in Bogor. The study used descriptive qualitative methods. The instruments used in this study include learning observation sheets, problem-solving tests, student observation sheets, and teaching reflections. The data obtained from the instrument is then processed in a simple descriptive manner, and the results are analyzed qualitatively. The results showed that the application of the PBL model was able to develop the problem-solving ability of grade VII students in mathematics learning. The PBL model is able to equip students to face the challenges of daily life by developing problem-solving skills. Therefore, the suggestion presented to the next researcher is to increase the number of meetings in applying the PBL model to gain a better conceptual understanding for students. Meanwhile, the advice addressed to teachers is to vary the problem solving, one of which is by giving group projects.
