The topic of the set is a basic concept in mathematics and its relationship is close to our daily life. However, some studies in Indonesia have found that the students have difficulties in solving the set problem. This can be due to the pattern of mathematics teaching in schools. This study aims to provide a design of learning in the set topic with Realistic Mathematics Education (RME) approach. The research questions are: (1) How is the design of mathematics learning in the topic of the set using the RME approach? (2) How do students learn the topic of the set by using the RME approach? This research method is design research with one cycle in SMP Dasana Indah Tangerang. The subjects were 24 students with one focus group, 5 students who had no errors in the initial test. Data of research obtained from sound recording, video, photos, and Student Activity Sheet, then be analyzed by comparing the Hypothesis of Trajectory Learning and Trajectory of Actual Learning. This study produces the Theory of Local Instruction, with four lessons, namely: (1) Determining the set and not the set; (2) Finding the concept of set of universe, subsets, empty set, and describing the models; (3) Finding the concept of intersection, union, and illustrating the models; (4) Find the concept of complement, difference, and describe the models, and use the models to solve the story problem. In the learning process, through grouping games and describe the model, student learning the notion of set enthusiastically and actively.Â Keywords: design research, set, realistic mathematics education approach

This study aimed to improve studentsâ€™ problem-solving skills and to describe the implementation of creative problem solving (CPS) model in Mathematics Education students of the Muhammadiyah University of Makassar in its program. This research was a classroom action research which involved 33 students with two cycles (1 cycle was 4 times meeting). The cycling stage consisted of planning, action, observation, reflection. Data collection through observation, test result, and student response were analyzed by quantitative descriptive analysis technique. The research finding was: Implementation of learning model (CPS) can improve studentsâ€™ problem-solving ability which can be seen from the increasing of solving ability from 63,03 (enough) to 77,72 (high). Effective learning (CPS) implementation with learning implementation indicators improved from less category to excellent category; student activeness increased from active category to highly active category, and student responses were in a very positive category. (2) Implementation of Learning Model (CPS) can be implemented through five stages: clarification of the problem; disclosure of ideas; evaluation; and implementation.Â Keyword: Learning Model, Creative Problem Solving (CPS), and Problem Solving Ability.

This research is motivated by students' mathematical problem-solving abilities. One way to improve students' mathematical problem-solving abilities is with the CTL learning approach. The purpose of this research is: 1) to know whether the average ability of mathematical problem solving of students who get learning with CTL approach is higher than the average problem-solving abilities of mathematical students who obtain conventional learning; 2) to find out whether the average mathematical problem-solving ability of the students who acquired the learning with Contextual Teaching and Learning (CTL) approach is higher than the minimum criterion value (KKM). This research type is quasi-experiment. The research design used is Nonequivalent Control Group Design. This research was conducted at SMP Negeri 1 Simpang Renggiang, East Belitung Regency in the academic year 2015/2016. Sampling was done by cluster random sampling. The sample in this research is class VII. 2 as the experimental class and class VII.3 as the control class. The research instrument used is a valid test instrument in the form of a matter of pretest and posttest in the form of a description. Data were analyzed using a non-parametric statistic test. The results of the research have shown that the average problem-solving ability of students who acquire mathematics learning with CTL approach is better than students who follow the conventional mathematics learning, the average problem-solving ability of mathematical students who gain learning with CTL approach less than or equal with KKM.Â Keywords: Mathematical problem solving, CTL approach, quasi-experiment, cluster random sampling

This study aims to describe: 1) teachers' understandings of skill competency assessment; 2) the application of skills competency assessment in mathematics learning; and 3) teachers' problematics in applying skills competency assessments. This research used the qualitative approach with descriptive research type. The study was conducted in the academic year 2017/2018 and implemented in 9 junior high schools / Islamic junior high schools in the DIY region. Research subjects were 11 mathematics teachers who are selected using purposive sampling technique. The data collected through structured interviewing methods, observation, and documentation. The data were analyzed by using inductive logic, from the particular to the general. The results show that: 1) teachers' understandings of skills competency assessment are quite good. Teachers understood the various instruments and assessment techniques but have not understood the assessment rubric used in each instrument yet; 2) the application of skills competency assessment has already done well but some were still constrained and have not accorded to the assessment standards; 3) teachers' problematics in applying skill competency assessment are: problems of understanding skill competency assessment, time, administrative complexity, student condition, assessment planning including the development of instrument and assessment rubric, and the implementation of skill competency assessment.Keywords: assessment execution, skill competency assessment, Curriculum 2013
