This research is motivated by the low ability of mathematical connections and the unavailability of teaching materials to improve students' mathematical connection skills. The purpose of this study was to develop mathematics teaching materials to improve students' mathematical connection skills with good characteristics and quality of teaching materials. This research uses qualitative and quantitative approaches. The method used is research and development (RD), with a modified Tessmer model design. The research subjects were class VIII students and a mathematics educator at a private junior high school located in Bandung district as well as a mathematics education lecturer. The instruments used were validation sheets, student questionnaires, educator questionnaires, observation sheets, and a set of mathematical connection tests. Data were collected through: validation of teaching materials, limited trials, and field trials. Based on data processing and analysis, two characteristics of the teaching materials developed consist of: material according to the 2013 curriculum; discovery learning model teaching materials design; evaluation according to mathematical connection ability indicators. The results of data analysis related to the quality of teaching materials show that the teaching materials developed are valid, practical, and effective. Thus it can be concluded that the developed teaching materials have characteristics to improve mathematical connection abilities and have valid, practical, and effective qualities.

This research was motivated by the low creative thinking ability of students in learning mathematics. One alternative learning that can be applied to improve student creative thinking ability is the Blended Learning (BL) model with the help of the edmodo application. The purpose of this study was to see the increase in creative abilities, accountability character, and the relationship between accountability characters and creative thinking ability through the application of the BL model assisted by the Edmodo application. The research method used is a quasi-experimental method. The population in this study were all student of class X in one of the secondary schools in Bandung Regency with a sample of class X IPA 1 as the experimental class and X IPA 2 as the control class. The instrument used was a creative thinking ability test. Based on the results of the Mann Whitney analysis of the creative thinking ability test of students, the increase in creative thinking ability that learn to use the BL model is better for student who use the Discovery Learning Model. The accountability character of students who use the BL model with Edmodo applications has a good interpretation. The accountability character of students has a positive relationship with creative thinking ability and low interpretation.

This research was motivated by the low mathematical communication skills and lack of students' self-confidence in learning mathematics. One alternative learning that can be applied to improve students' mathematical communication skills is the Make a Match cooperative learning model. The purpose of this study was determine self-confidence and improve mathematical communication skills of junior high school students. The research method used in this study was a quasi-experimental method with Nonequivalent Pretest-posttest Control Group Design. This research was conducted at a junior high school in Bandung Regency. The research sample was students of class VII-B as the experimental class and class VII-C as the control class. The experimental class uses the make a match type cooperative model, while the control class uses the discovery learning model. The instrument used was a test of mathematical communication skills, a confidence questionnaire and an observation sheet of educator learning activities. The results of the study were analyzed using t-test. Based on the results of the analysis, it can be concluded that the self-confidence of the two classes had a very good interpretation. Meanwhile, mathematical communication skills of students whose learning using the make a match type cooperative model was better than mathematical communication skills of students whose learning uses discovery learning models.

This study aims to describe the students’ mathematical critical thinking skills in online learning. This type of research is a case study with a qualitative approach and descriptive qualitative research design and data collection techniques in the form of testing and interviews. The subjects in this study were three students 7 grade students of Junior High School 1 Sukaraja, taking the subject in this study using purposive sampling. Based on the results of the study, that students who have the ability to think critically mathematically high category that is collecting and compiling information needed, find ways that can be used to solve problems, analyze data and draw conclusions and similarities needed. Students who have the ability to think critically mathematically categories are fulfilling one to two components of mathematical critical thinking that is finding ways that can be used to solve problems analyze data. Students who have low category mathematical critical thinking skills do not meet the four components of mathematical critical thinking ability.

This research is an alternative to overcome the low critical thinking skills, namely the development of evaluation tools to measure student’s critical thinking skills. This research and development begins with determining the research objectives, namely developing a critical thinking ability test and knowing the validity, reliability, discriminating power, and level of difficulty of the test. Critical thinking ability evaluation instrument on comparative material for class VII Junior High School include in Research and Development (RD). The RD model used is the Thiagarajan 3D model, which includes 3 stages namely: define, design, and develop. The instrument in this study were critical thinking skills test and validation sheets. The subject of this research is class VII 31 Junior High School Bandung, totaling 15 people. The assesment instrument developed is in the form of descriptive questions. The data from the validation of the instrument’s feasibility by the expert is declared valid. The results of the analysis of the validity of the items based on the results of the analysis of the validity of items using the Product Moment correlation technique can be seen that the level of validity of the evaluation instrumen is declared high, while the reability value of 0,72 with a high interpretation. Analysis of the difficulty level of the instrumen obtained an average scor of 0,22-0,54 in medium-difficult category. The discriminatory power of the instrumen shows a sufficient category with an average value of 0,31-0,78.

This research is motivated by the low ability of understanding and self-efficacy of students. One alternative is to apply Cooperative Type Talking Stick learning. The purpose of this study was to determine self-efficacy and increase students' understanding ability using the Cooperative Type Talking Stick model with students who used the Discovery Learning model. The research method used was a quasi-experimental method, with a pretest-posttest control group design research design. The study was conducted at one of the State Junior High Schools in Bandung Regency, with the sample of students in class VII-A as an experimental class and class VII-B as a control class. The experimental class uses the Cooperative Type Talking Stick model, while the control class uses the Discovery Learning model. The instrument used was a self-efficacy questionnaire, a mathematical understanding ability test, and an observation sheet of educator activity. The results of the study were analyzed using two mean differences (t-test). Based on the analysis results, it can be concluded that the self-efficacy of students who use the Cooperative Type Talking Stick model and students who use the Discovery Learning model, both have very good self-efficacy qualifications. While increasing students' mathematical understanding ability using the Cooperative Type Talking Stick model is better than students using the Discovery Learning model.
