The problem solving ability is needed for the students to be able to face the challenges of education on cognitive aspects. Meanwhile, in the affective aspect, the students’ activities also play an important role in the process of learning mathematics in higher education. Armed with activities and mathematical problem solving ability, they are expected to be more adaptive in their efforts to find solutions for each problem. The purpose of this research is to improve the activities and ability to solve mathematics problems in the second semester students in the Integral Calculus course using the Cognitive Growth model. This is a Classroom Action Research (CAR in the even semester 2018/2019). The subjects of this research are the second semester students of the Mathematics Education Study Program at a higher education institution in Magelang, Central Java, Indonesia. The data collection techniques in this research are the test, observation, and interview. The percentage for the aspect of the students’ activities in the first cycle = 51.51%, the second cycle = 58.56%, and the third cycle = 65.48%. The percentage of improvement in the students' mathematical problem solving ability in cycle I = 45.08%, cycle II = 40.08%, and cycle III = 56.59%. Therefore, it can be concluded that the application of the Cognitive Growth model can improve the activities and problem solving ability in the second semester students in the Integral Calculus course.

The Relationship

This research is a survey research that is focused on the ability of students to solve mathematical problems. The purpose of the study was to determine the relationship between learning motivation and self-concept of students with the ability to solve mathematical problems, both together and individually. The population of the study is 2017/2018 odd semester students of Mathematics Education Study Program FMIPA UNM Makassar. Sampling is used random class. Data obtained through instruments: 1) learning motivation scale, 2) self concept scale, 3) test mathematical problem solving ability. Data were analyzed by multiple regression. The conclusions obtained are 1) learning motivation has a positive relationship with mathematical problem solving abilities, 2) self-concept has a positive relationship with mathematical problem solving abilities, and 3) contribution of motivation and self-concept to mathematical problem solving by 71%. It is expected that other researchers to expand the population and add independent variables that theoretically adhere to mathematical problem solving abilities

This research is a quantitative research by true experimental design. Research design is random, pre test and post test. Sample is prepared randomly by two group; experiment and control group. Experiment group is prepared by problem based learning with 13 students in this group, while control group is taught by conventional method with 10 students in this group. Tests are applied in data collecting, then analyzed by t-test. Data analysis shows at a = 0,05 there was dan = 1,72 atau . It can be concluded that the increase in mathematical problem solving from experiment group is relatively better than those in control group in Applied mathematics II Course in Industry Technics Study Program, South Aceh Polytechnic.

Mathematical Resilience

This study aims to determine the relationship and the extent of influence between mathematical resilience and students' mathematical problem-solving abilities in basic mathematics courses. This research is motivated by the perception of students who tend to be negative towards mathematics as well as an attitude of lack of confidence and easily give up in solving the given questions. In addition, students' mathematical solving abilities are also classified as low, even though this ability is very important because it is the basis and general goal of learning mathematics. The method used in this research is quantitative descriptive method. The population in this study were all Semester I students of the Computer and Informatics Engineering study program at STKIP AL Maksum Langkat which consisted of 5 classes and took basic mathematics courses, while the research sample was taken using purposive sampling technique, which is a technique of determining and taking the specified sample. by researchers with certain considerations. The sample consisted of 35 students. The instruments in this study were test questions in the form of mathematical problem-solving abilities and non-test questions in the form of a mathematical resilience scale. Then the data is processed using hypothesis testing techniques, correlation analysis and simple regression assisted by SPSS and Microsoft Excel. The results showed that there was a positive relationship between mathematical resilience and students 'mathematical problem-solving abilities with the effect of mathematical resilience by 41.3% on students' mathematical problem-solving abilities.

This study aims to determine whether there is a significant influence between mathematical problem solving abilities of students who are taught using cooperative learning pair check model is higher than the mathematical problem solving abilities of students who are taught by the lecture method in Mathematics teaching planning courses. The population in this study were all V semester students of the Mathematics Education Study Program FKIP UNA, taking a sample of two semesters totaling 72 students through a purposive sampling technique. The results of the study from the experimental semester obtained an average pretest of 65.1 and posttest average of 80.8. Whereas from the semester of control the average pretest was 65.5 and the posttest average was 75.1. Analysis of posttest data using the t test at the level of α = 0.05 obtained tcount = 2.75 while t table = 1.98 turned out t_count> t_tabel so that Ho is rejected and Ha is accepted. Then it can be concluded that the mathematical problem solving abilities of students taught by using the pair check learning model are higher than the students' mathematical problem solving abilities taught by the lecture method.

Problem solving is the main focus in learning mathematics at the primary and secondary school level. Prospective teachers must be prepared as well as possible as problem solvers and problem solving instructors. The purpose of this study was to describe the prospective teacher's ability to make a problem solving question based on category of good mathematical problem solving questions. The type of research used is descriptive qualitative.The research subjects were students of semester VI of the 2019/2020 academic year of the IAIN Takengon Mathematics Education Study Program. Based on the research results, it shows that the subjects in general already understood the theory of problem solving , but this understanding did not always directly proportional to the ability to make a mathematical problem solving question.
