This research is a quasi-experimental study that aims to determine the comparison of students' mathematical communication abilities with the cooperative learning model of the NHT and PPT media in class VII SMP Negeri 02 Ngabang. The population in this study were all students of class VII SMP 02 Ngabang consisting of 3 classes. The sample in this study was taken by using the Random Sampling Cluster technique. Class VII A as class I experimental class with 24 students and class VII B as a experimental class II with 24 students. The instruments used were pretest and posttest in the form of description. Data analysis uses the t test with a significance level of 5%. The results showed the average posttest for the NHT class was 72.5 and the average posttest for the PP class was 66.666. From the posttest hypothesis test results obtained t hitung> t tabel (1.9522> 1,667). Because t_hitung> t_tabel, H_0 is rejected and H_a is accepted. This means that students' mathematical communication skills taught with the NHT are better than using Power point media.

This type of research is quasi-experimental. This study examines the Learning Start with a Question (LSQ) model in improving students' mathematical communication skills through the learning module. The population in this study were all students of mathematics education from the Teaching and Education Faculty, from semester V with the sample being students of class A1 and class A2. This study was divided into two learning groups, namely the experimental group by applying the Learning Start Learning Model with a Question (LSQ) and the control group with conventional learning. Based on the results of calculations using the t-test at the significance level α = 0.05 obtained a ttest of 4.64 with a significance value of 0.003, while the ttable of 1.76. Because tcount > ttable (4.64 > 1.76) and significance < 0.05 (0.003 < 0.05). It can be concluded that increasing students' mathematical communication skills by applying the Learning Start Learning Model with a Question (LSQ) and using the learning module is better than the mathematical communication skills of students who obtain conventional learning without learning modules.

This research was motivated by the lack of learning tools that can improve students' Mathematical Communication Skills (KKM). Activities that can encourage students to improve KKM have not been designed by the teacher in the learning device properly. This study aims to produce learning tools by applying Problem Based Learning models to improve KKM. This development research used the ADDIE development model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The results of Syllabus, RPP, LKPD and KKM validation results showed highly valid criteria with percentages of 91.67%, 91.30%, 89.09%, and 87.15%, respectively. Practicality results indicate a very practical criterion with the percentage of small group trials at 95.57%, large group trials at 96.07%, and teacher responses at 96.25%. The effectiveness test results state that KKM of students who use learning tools with PBL models is better than KKM of students who use conventional learning.

Learning that challenges students to communicate their ideas will make students try to solve the problems they experience in learning mathematics, but the ability of students to communicate and solve problems is very dependent on their awareness of what they know and how to do this. This is related to their metacognitive awareness. Metacognition is the awareness of our thinking so that we can perform specific tasks, and then use this awareness to control what we do. This research was carried out with the aim of: 1) knowing the achievement of students' mathematical communication skills after using the metacognitive approach compared to those using conventional learning, 2) knowing the increase in mathematical communication skills of students who received learning with a metacognition approach and those who received conventional learning, 3) knowing the response students towards learning by using metacognitive learning. Data were collected from students' mathematical communication skills tests in the form of essay questions and student questionnaires. Questionnaires were given to all experimental class students with the aim of knowing students' responses to mathematics learning using metacognition learning. This research is a quasi-experimental study with an experimental class design, namely Pretest-Treatment-Postest, while the control class is Pretest-Postest. From the results of data analysis with a significant level of = 0.05, it shows that the achievement of mathematical communication skills of students who get learning with a metacognitive approach is better than conventional learning. The improvement of mathematical communication skills of students who received mathematics learning with a metacognitive approach was better than the mathematical communication skills of students who received conventional learning. The improvement in mathematical communication skills of students who received mathematics learning with cooperative learning of the TGT type was in the medium category, while students who received conventional learning had an increase in the low category. Based on the results of the analysis of student responses to metacognition learning, it shows that students have a positive attitude towards learning mathematics with a metacognitive approach.

This study aims to determine the effect of GeoGebra software on junior high school students' mathematical communication skills. The method used is the quasi-experimental method. This research was conducted at Pasundan Rongga Middle School. With class VIII A as an experimental class with 28 students and class VIII C as a control class with 28 students. This study uses instruments that have been tested and declared valid and reliable. The instrument was adjusted to the indicator of mathematical communication skills with the number of questions tested as many as 5 questions to obtain pretest and posttest data in both the experimental class and the control class. Data testing is done using normalized n-gain formula so that the n-gain data obtained is processed using the SPSS 20 application to perform parametric statistical tests. The results showed that the mathematical communication skills of students who learned using GeoGebra software were better than students who learned without using GeoGebra software.
