Through classroom action research, researchers seek to improve students 'mathematical problem solving abilities on mathematical induction material by using nested integrated learning methods and explore students' attitudes towards the application of the given learning model. The study was conducted during two cycles which included four stages of learning, namely: planning, implementation, observation, and reflection. The study was conducted in the odd semester of the 2019/2020 school year involving 34 students of class XI MIPA-2 SMAN 1 Garawangi, Kuningan. There are 2 types of research instruments used, namely tests and questionnaires. Based on the test results, it can be seen that in the post-test, the N-Gain index obtained was 0.61 (moderate). Meanwhile, based on the results of the questionnaire, it can be seen that 100% of students show a positive attitude. Thus, it can be concluded that the nested type integrated learning model can improve students' mathematical problem solving abilities on mathematical induction material and get a good appreciation with the presence of a positive attitude shown by all participants.

This research is aimed to investigate the students’ problem-solving competency after learn by using discovery learning model and students’ problem-solving ability after learn by using problem-based learning model. Therefore, this research is aimed to investigate differences problem-solving ability of mathematics between students who get discovery learning model and problem-based learning model. The population used in this research was a student in grade VII in one of junior high school in West Bandung Regency. The sample was student class VII B for the first experiment class and VII C for the second experiment class with 35 students in every class. The method in this research was a quasi experiment by using two group post-test only design. The instrument in this research is post-test about problem-solving of mathematics. Based on the research, it can be concluded that there is a difference between the mathematical problem-solving competency of students who get discovery learning model and problem-based learning model. Nevertheless, the qualification of problem-solving competency between of students who gets discovery learning model and problem-based learning model, are including the medium category

This study aims to determine the effect of the use of the super-scaled model of scaffolding on students' mathematical problem solving abilities. The sampling technique used was cluster random sampling with 3 classes namely experimental class 1 (the class was treated with scaffolding assisted superememe learning model), experimental class 2 (superitem learning only) and control class (the conventional treatment class). Hypothesis testing used is anava 1 cell path is not the same. The results of the study found that there were differences in students' mathematical problem solving abilities by using learning models of scaffolding assisted supermarkets. Furthermore, the mathematical problem solving ability of students with the super-intensive learning model assisted by scaffholding is the same as the mathematical problem-solving ability of students using superemit learning models. The mathematical problem solving ability of students with superficial learning models assisted by scaffholding is better than the students' mathematical problem-solving abilities using conventional learning models. Furthermore, the mathematical problem solving ability of students with superemit learning models is the same as the mathematical problem solving ability of students using conventional learning models.

This article is based on the fact that problem-solving is a basic skill that every student should possess. To improve the student`s mindset through the effort to find problem-solving independently, so the learning activities should be centered on the students. The purpose of this study is to determine the comparison and improvement of students mathematical problem-solving abilities, as well as student attitudes toward the learning model problem-centered learning and problem-based learning. The research method used was a quasi-experiment with purposive sampling. The first experimental class that was class VIII I that got problem-centered learning model as much as 31 students, and the second experimental class that was class VIII H who got the problem-based learning model as many as 31 students. From the research and statistical calculations result, obtained the conclusion that the mathematical problem-solving ability students who got the model centered learning problem was better than students who got the model of learning problem-based learning. Meanwhile, for improvement of problem-solving abilities of mathematical students who got the learning model problem-centered learning and problem based learning each intermediate interpretation. And generally, the students’ attitude to the learning of mathematics by using the learning model problem-centered learning and problem-based learning are well interpreted.

The purpose of this study was to determine the effectiveness of the Problem Based Learning model and the Cooperative Learning model Think Pair Share type assisted by geogebra. The type of research used is experimental research. Data collection methods consist of documentation, testing, and observation. Data analysis in this study used analysis of variance, regression, and proportion test. The results of this study indicate that students who get geogebra-assisted PBL models have the same mathematical problem solving abilities as students who get geogebra-assisted TPS models, and both of these learning models produce students' mathematical problem-solving abilities better than conventional learning models. The results also showed that in the PBL and TPS models assisted by geogebra, there was an influence on students' learning activeness with their mathematical problem solving abilities.
