Abstract

Problem solving is an important element in solving real life problems. When students are solving mathematical problems, students are faced with several challenges such as difficulty in understanding the problem because of problems that students have faced before. From the results of the teaching and learning activities that have been carried out, it can be concluded that the questions given to 36 students show that students' problem solving abilities are still low. The average obtained was 63.75 and classical completeness was 67%. Based on the results of the PISA survey in 2018, Indonesia was ranked 64th out of 65 countries that took part in the test. The aim of this research is to determine the increase in problem solving abilities using a metacognitive approach. This research uses a meta-analysis method by reviewing several articles in national and international journals. This meta-analysis is quantitative because it uses numerical calculations and statistics. This meta-analysis research uses 12 samples of relevant journals in national journals. Based on the results of the meta-analysis, it can be concluded that the articles that have been analyzed have an effect size value in the very high category of 17% of all articles, an effect size in the negligible category of 17%, an effect size in the high category of 17% of all articles. . The effect size in the medium category is 17% of the entire article. The effect size in the low category is 25% of the entire article. Based on the calculation results, the t_count value was 9.63 and the t_table value was 1.96; Thus the conclusion is obtained t_count=9.63>t_tabel=1.96. So H_0 is rejected. So, the average problem solving ability of experimental group students is more than the average of control group students.

Abstract

Problem solving ability is one of the abilities that must be possessed by students of the five abilities in mathematics education. The problem-solving ability and independent learning character of SMA Negeri 5 Semarang students still need to be improved. One of the efforts to enhance problem-solving skills and the character of learning independence is to apply Problem Based Learning with the help of Math Magazine. This research aims (1) to test the effectiveness of Problem Based Learning assisted by Math Magazine and (2) to describe problem solving abilities with Problem Based Learning assisted by Math Magazine in terms of learning independence. This research used a mixed method research method with a sequential explanatory research design. The population in this study were students of class XI SMA Negeri 5 Semarang for the 2022/2023 academic year. The selected sample was 33 students in the experimental group and 28 students in the control group. Data collection methods were carried out by tests, independent learning questionnaires, and interviews. The results showed that (1) Problem Based Learning assisted by Math Magazine on the ability to solve problems exceeds classical completeness by 91%, (2) The average problem solving ability in the Problem Based Learning model assisted by Math Magazine is better than the problem solving abilities of control class students, and (3) the average problem solving ability in the Problem Based Learning model assisted by the Math magazine is more than 70.
