Education is a conscious effort to change character, morals, morals and also fosters creativity in thinking. Creative in thinking is something that is very urgent in life. Education has value to be able to solve problems precisely and quickly. The purpose of this study was to determine the extent to which the Collaborative Role of Creative Problem Solving and the Quiz Team Method played a role in increasing creative thinking. This study uses a qualitative descriptive analytical approach, which is one of the approaches used in qualitative research to understand phenomena in detail and depth. Researchers collect data through interview techniques, observation, case studies, or document analysis. Researchers used the class action research method (CAR). CAR involves iterative cycles of planning, action, observation, and reflection in order to achieve continuous improvement in student learning and achievement. The results showed that learning Creative Problem Solving (CPS) and quiz teams can improve students' creative thinking and this method is very good to use because students feel happy and not bored.

Mathematics is one of the subjects taught at all levels from basic education to higher education, which has a significant role in preparing students to have the ability to think logically, analytically, systematically, critically and creatively, as well as have the ability to work together. One of the activities in learning mathematics at school is through problem solving. Problem solving aims to see students' understanding of a material. Mathematical problem solving ability is a very important part of learning mathematics. However, in reality, the problem-solving ability of junior high school students' mathematics is still very low. From these problems, then one of the lessons that can improve the ability to solve mathematical problems is Problem Solving learning. One of the factors that influence differences in problem solving ability is learning style. Learning styles have a close relationship and influence on the learning process in order to achieve learning goals. With students knowing their learning style, learning Problem Solving can be done easily. The subjects of this study were students of class VIII A MTs Plus Sunan Drajat Kedungsantren Bojonegoro. The purpose of this study was to determine the effectiveness of Problem Solving learning on mathematics learning outcomes when viewed from students' learning styles. The type of research used is quantitative research with the One Group Pretest-Posttest Design. The results showed that testing the data on mathematics learning outcomes with the Paired Sample T-Test stated that the t_count value was -9.726. The t_count value is negative, because the pretest average value is lower than the posttest average value. In this case, the t_count value can be positive so that it becomes 9.726. Meanwhile, the value of t_table with α = 0.05 and degrees of freedom (dk=n-1) with 24 students is 1.714. Then it can be seen that t_count > t_table, then H0 is rejected and Ha is accepted, meaning that there is a significant difference. So it can be concluded that the application of the Problem Solving learning model is quite effectively carried out in the teaching and learning process for class VIII A students of MTs Plus Sunan Drajat Kedungsantren on the material of geometric shapes on the flat sides of cubes and blocks.  

This article discusses the teacher's perception of Problem Based Learning to improve students' thinking skills. Critical thinking is something that every individual has in developing abilities. This model can be applied to increase student excellence in thinking to find a way out of a problem through direct experience and student knowledge. Problem Based Learning is a learning model that is given based on problems, where students are given a problem and asked to solve the problem critically. Researchers use descriptive qualitative because the information collected is in the form of verbal. Samples were taken from fifth grade elementary school teachers. This study states that students' ability to think in grade V elementary school increases by implementing PBL-based learning. Before using the PBL model in class V students, learning was too monotonous, lack of enthusiasm and passivity, and students also had difficulty understanding the material, less sharp dexterity of opinion, students' excess in thinking was less developed and less flexible. However, after using the PBL learning model, students' ability to think in class V is increasing in solving problems, students also become more responsive to the essence of the problem, students also become creative, active and critical and are increasingly able to find solutions to a problem, as well as students' thinking skills. growing and flexible.

This research was explored in depth from the contextuality aspect of the study, and the research methodology design aspect. With a mixed method design (a combination of qualitative and quantitative methods), the results of data analysis show that the implementation of the CTL concept at SMK Darunnajah II Bogor is carried out by following its main components, namely constructivism, inquiry (finding and solving problems), questioning (asking questions). ), learning community (learning community), modeling (modeling), reflection (reflection), and authentic assessment (authentic assessment). The CTL approach implemented in the entrepreneurship subject at Darunnajah Cipining Vocational School, in addition to teaching students to be more critical in the learning process, to be more active, sensitive, and creative in analyzing issues relevant to entrepreneurship subject matter, teachers also teach students to in the context of the values ​​taught by Islam and internalized at the Darunnajah Islamic Boarding School, namely the principle of mutual benefit, not tyrannizing, and not dominating or harming each other, and intended to build a better life and economy for the ummah. The outline of the results of the analysis of student perceptions regarding the implementation of CTL in the entrepreneurship subject at SMK Darunnajah II Bogor shows that as much as 91.38% of the total respondents stated that the CTL concept was very effective in the context of the relevance of material to everyday life experiences and reflections on learning from problem analysis . Keywords: contextual teaching and learning, reflection, inquiry, learning model.

This study aims to find out how to improve students' mathematical creative thinking skills after using the Problem Based Learning model assisted by Geogebra media and to find out how students' answers process in solving problems on the mathematical creative thinking ability test after applying the Problem Based Learning model assisted by Geogebra media. This type of research is Classroom Action Research (PTK) which was conducted in two cycles, the subjects in the study were class IX-3 MTs Citra Abdi Negoro, totaling 27 students. This research is said to be successful if it meets the indicators of success, namely, (1) The level of students' mathematical creative thinking ability increases with a value of ≥ 85% at least in the medium category, (2) The process of completing student answers with a value of ≥60% at least in the good category, (3) The results student and teacher observations show a good category. Based on the results of the study, the average initial ability test score of 58.10 increased to 61.34 in cycle I and 80.55 in cycle II. There was also an increase in classical completeness, in the creative thinking ability test of 8 students (29.63%) in the initial ability test increased to 12 students (44.44%) in cycle I and 25 students (92.59%) in cycle II. For the process of student answers from cycle I with an average presentation of 50 students' answer processes, 31% increased to 70.67% in cycle II. Based on the results of the study it can be concluded that the Problem Based Learning model assisted by Geogebra media can improve students' creative thinking skills.
