The results of the preliminary study indicate that the learning tools used by the teacher do not meet the 2013 curriculum rules. This study aims to produce learning tools with the application of discovery learning to improve Mathematical Problem Solving Ability (KPMM) on social arithmetic materials for grade VII junior high school. This study used the Borg and Gall development model with stages: (1) research and data collection; (2) planning; (3) development of learning tools; (4) limited trials; (5) product revisions; (6) field trials; (7) product revisions; (8) final product test; (9) revision of the final product; and (10) dissemination and implementation. The validation results showed that it was very valid with consecutive average percentages for KPMM problems that were 94.64%, syllabus was 90.10%, RPP was 93.14%, and LKPD was 92.60%. In the final product test phase, learning tools were used through pre-experimental research to see the increase in KPMM. The final product test results indicated that there was an increase in KPMM of students using learning tools. This means that the learning tool with the application of discovery learning in social arithmetic material in class VII SMP has been valid, practical, and effective.

This study aims to determine the effect of Group Investigation type cooperative learning on mathematical problem solving abilities and confidence of class VII students of Rembang 2 State Junior High School 2017/2018 school year. The population in this study were seventh grade students of Rembang 2 State Junior High School 2017/2018 school year. The sample in this study is class VII E as the Experiment class and VII C as the Control class which is taken by Cluster Random Sampling technique. The instrument used in this study is post test. Post test results were obtained after students in the experimental class followed Group Investigation cooperative learning and the control class followed direct learning. Post test results were processed using IBM SPSS Statistic 21 Software by performing the Mann Whitney test for post test results and Independent t Test tests on questionnaire results. The sig value obtained on the Mann Whitney test for post test results is 0.0355 and the sig value on the Independent t-test for the results of the questionnaire is 0.0075. So it can be concluded that students' mathematical problem solving and self-confidence abilities that follow Group Investigation type cooperative learning are better than mathematical problem solving abilities and confidence by using direct learning.

Pbl Model

This research was motivated by the low ability of Mathematical Problem Solving (KPMM) of students. In order to improve KPMM, teachers can do designing the learning process. This study aims to develop mathematical learning tools that are valid, practical and effective. The development model used the Borg and Gall model. The research instrument consisted of syllabus validation sheets, lesson plane (RPP), student worksheet (LKPD), observability of implementation, student questionnaire responses and KPMM test instruments. The result shows the mathematics learning kit using the PBL model was already valid which is for the syllabus was 85.41%, RPP was 85.11%, LKPD was 88.67% and the test instrument was 81.71%. The learning kit fulfills the practicality requirements in large group trials with an average questionnaire of students responses of 91.99% and an average of 94.58%. Effective mathematics learning tools is to improve KPMM of students with student learning outcomes that is based on the achievement of KKM with the percentage of completeness reached is 88.24%. Development of learning tools can significantly improve students mathematical problem solving abilities at a significant level of P = 0,000 with α = 0.05. Thus, it can be concluded that the development of mathematics learning tools by applying problem based learning can improve students mathematical problem solving abilities

This study aims to produce effectiveness from the development of learning tools through the concept of algebraic forms using Cognitive Conflict-Based Learning (PbKK) models for mathematical problem-solving abilities that are implemented in the Learning Implementation Plan (RPP) and Student Worksheet (LKPD) that are valid and practical. The method used is the Plomp design research model which consists of three phases, namely the preliminary research phase, the development phase (development or prototyping phase) and the assessment phase. The subjects of the study were the seventh grade students of junior high school. Data collection techniques used was posttest tests from two classes, namely the experimental class and the control class. Data analysis techniques are using the Independent-Sample T Test. The analysis shows that p-value = 0.034 <0.05 means that there are significant differences between the two classes. So, the development of Cognitive Conflict-based learning tools has a positive impact on students' mathematical problem solving abilities in algebraic form material.

This study aims to determine the effect of students' mathematical dispositions on mathematical problem solving abilities of students in class VII of SMP. The type of research used is quantitative. The sample in this study was class VII A, amounting to 30 people who were selected using simple random sampling from 6 existing classes. The type of data in this research is primary data with data collection used using a disposition questionnaire consisting of 28 items and tests consisting of 5 items of description. Testing the hypothesis in this study using a simple regression test. After the data is analyzed the regression equation is obtained as follows: Y = 16,312 + 0.523X. before testing the hypothesis, the data normality test and linearity test were carried out. Based on the data analysis, it was found that the t-test = 3.296 with significance = 0.003 and table = 2.048. then t count = 3.296> 2.048 = t table means that data is normally distributed. To see the achievement of the disposition indicators of junior high school students in the junior high school class, the average of each indicator is calculated and the achievement of the mathematical disposition indicator is 50.08%. Whereas for grouping mathematical dispositions, problem solving abilities obtained the highest dispositions having an average of 63.04, moderate dispositions having an average of 43.56, and low dispositions having an average of 40.51. Thus, it can be concluded that there is an influence of mathematical disposition on mathematical problem solving abilities of students of junior high school class.
