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.

The problem in this research is the lack of readiness of the practitioner students to practice in the field and the low ability ofhigh-order thinking of the students of praktikan. The purpose of this research is to know the comparison by using four activelearning models to improve students' high thinking ability. This research uses Research and Development method, with firstphase design, preliminary study done by applying qualitative descriptive approach. The second stage, the development of modeldesign, teaching materials web-based learning media by applying a descriptive approach, followed by the application of smallscopes of model design, teaching materials, and web-based learning media by applying the experimental method (Single OneShot Case Study). The results of the limited trials show that the average value of higher-order thinking skills for the guideddiscovery-based learning model and peer instruction is higher than the MinDS and Making A Conversation type of learningmodel. The findings of the limited trial result of the four guided discovery learning models are more suitable for improvingthe activity as well as the material content of the design of discovery learning activities (KBP) still confuses the students, sothere needs to be improvement.

The background of this research is the low mathematical proofing ability of students. One alternative learning that can be applied to improve students' mathematical proofing ability is the PACE learning. The purpose of this study is to find out: whether the students' mathematical evidentiary ability using the PACE learning is better than students who use PBL (Problem Based Learning) models, and how students respond to mathematics learning using the PACE learning. The research method is quasi-experimental, with a pretest-posttest control group design research design. The study was conducted in one of the state high schools in the city of Bandung. The study population was all students of class XI, the sample students of class XI MIPA-1 as the experimental class were given the PACE treatment and class XI MIPA-2 as the control class was given the PBL treatment. The research instrument was a mathematical proofing ability test, a student questionnaire, and an educator observation sheet. The results of the research are quantitative and qualitative data. Analysis of quantitative research results using t test, while qualitative results use a Likert scale. Based on the analysis of the results of the mathematical proofing ability test, it can be concluded that: the mathematical proofing ability of students by using the PACE learning model is better than the students who use PBL learning models, and the students' responses to mathematics learning using the PACE learning are positive.

This research is motivated by the existence of a driving school program, the lack of teaching materials used in schools, and the difficulties of students in solving cross product problems, as well as learning that is only centered on educators. So it is necessary to develop cross product teaching materials whose learning is centered on students. The teaching material developed in this research is a cross product teaching module based on problem based learning related to mathematical problem solving abilities. This study aims to determine the level of validity, effectiveness, and practicality of teaching modules. The research method used is Design-based-Research (DbR) with the plomp model. Sources of data in this study are validators of media experts, material experts, students, respondents of mathematics teachers. Based on the results of the analysis carried out, it can be concluded that the teaching module developed is valid, small group trials are effective and the response from educators is very practical. It is recommended that further research be carried out on a large scale, using different mathematical abilities and learning models.

The purpose of the study was to find out the description of the mathematical problem solving abilities of VIII-C class PENIDA Katapang Junior High School students in circle material. The research uses a qualitative approach with a descriptive method. Data collection techniques using documents, tests and in-depth interviews. The research subjects were six people consisting of students in the upper, middle and lower categories. The research subjects were determined by purposive sampling technique by using documents study. To find out the problem solving ability of students using test questions that have been validated. In-depth interviews were conducted to find out the low problem solving abilities of student and their causes. The results show that the problem-solving abilities of students were included in the weak category at each level, namely: (1) for the upper category, it was sufficient; (2) for the medium category including less; and (3) for the lower category including very less. So that the overall student problem solving ability is at a low level.

The main problem in this study is students' ability to think mathematically in solving mathematical problems in learning social arithmetic in their class through minimum guidance-based learning (PBL and DL). This research uses a mixed method to look at the description of students' mathematical thinking abilities and the tendency of these abilities based on students' self-efficacy levels. The results showed that the increase in students' mathematical thinking skills at each level of low self-efficacy based on n-gain calculations. In addition, there is no significant difference in the scores for improving students' mathematical thinking skills based on the learning model and the level of self-efficacy. There is no significant interaction between the Learning Model and the Level of Self-efficacy in determining the increase in the average score of students' mathematical thinking abilities. Other findings show that students with low self-efficacy tend to have limitations in the ability to think mathematically in the process of conjecture and convincing. On the other hand, students with moderate and high self-efficacy have more complete mathematical thinking abilities, including specialization, generalization, conjecture, and convincing. However, in the process of conjecture and convincing, two sub-processes are found, namely knowledge modification using factual knowledge, contextual tools, or substantive thinking, as well as the process of selecting relevant information in solving problems. Therefore, the two groups are divided into four groups based on the way students use conjecture and convincing mathematical thinking abilities, namely: (1) students use specialization mathematical thinking skills based on the knowledge learned from the teacher, (2) students use specialization mathematical thinking abilities based on knowledge acquired in everyday life, (3) students use convincing mathematical thinking abilities by examining the formula used or based on knowledge learned from the teacher, and (4) students use convincing mathematical thinking abilities based on the knowledge obtained in everyday life (factual knowledge).
