During the current Covid-19 pandemic, the learning system in all educational institution is shifted from face to face to online learning, including universities. This study aims to describe the results of the mathematical communication skills of class B students of Mathematics Education from Ahmad Dahlan University for the 2019/2020 academic year during online learning during the Covid-19 pandemic and to examine students' mistakes in solving differential calculus problems regarding the minimum, maximum material. This study employed descriptive qualitative research. The research instrument used is a test and interview guide. The data are collected using tests and interviews. The research subjects were selected by stratified random sampling technique so that 6 students are classified into high, medium and low categories. The questions are in the form of a description of one question with six questions. The results showed that students' mathematical communication skills on indicators (1) restating information was done appropriately, (2) writing down ideas or problem-solving steps clearly and precisely, some were not thorough, (3) presenting information using graphic images again. There are still things that they couldn't understand and (4) Writing down the answers according to what is known and are asked using mathematical formulas, some are still wrong because they are not accurate.

This research is a quasi-experimental study which aims to describe the effect of cooperative learning type Think Pair Share (TPS) on students' mathematical communication skills, and to find out the percentage of students' activeness in participating in learning and knowing students' positive responses to learning. The output that will be generated in this study is that students can be more active in the learning process, more active in solving mathematical problems, and can be more confident in expressing their answers in public so that after applying cooperative learning models the Think Pair Share (TPS) mathematical communication skills of students will be better. The research subjects were divided into 2 groups, namely the experimental group taught using the cooperative learning model Think Pair Share (TPS) type, and the control group taught using Conventional learning models. Each group is taught with the same frequency of meetings with the same material. The results of the study show that the application of the cooperative learning model Think Pair Share (TPS) influences students' mathematical communication skills

Mathematical communication ability is an important ability to have students. This is because by having these abilities, students can communicate ideas or mathematical ideas both orally and in writing. However, based on preliminary studies in the form of mathematical communication and class observation tests conducted by researchers in one class at SMP Negeri 8 Kota Tangerang Selatan showed that students' mathematical communication ability is still low. The efforts that can be done is to apply a model of learning that can train and cultivate students' mathematical communication ability by applying the learning cycle 5e  model. The purpose of this study is to determine whether the average of improvement mathematical communication skills of students who get a learning model learning cycle 5e higher than students who obtain conventional learning. This type of research is quasi experiment. The research design used is a nonequivalent control group design. The population in this research are the students of class VII.1, VII.2, and VII.3 SMP Negeri 8 Kota Tangerang Selatan and the sample is the students of class VII.2 as the experimental class and class VII.3 as the control class. The sampling technique used random cluster sampling. Hypothesis testing of research done by the parametric test (t-test). In this research, it can be concluded that the average improvement mathematical communication ability of students who get the learning cycle 5e model is higher than students who get conventional learning. Keywords:  Mathematical communication skill, learning cycle 5e model, quasi-experiment

Mathematical communication skills are one of the abilities that students must have to make it easier to solve problems contained in mathematics itself and in everyday life. Because if students have mastered mathematical communication skills, it will make it easier for students to take deeper learning. This study aims to analyze the difficulty of students' mathematical communication skills using the Google Classroom Application in the Algebra course. This type of research is descriptive qualitative. The subjects of this study were tree semester students who took Algebra courses in the Mathematics Education study program at Universitas Muhammadiyah Tapanuli Selatan, academic year 2020/2021 as many as 15 people. The instrument used in this study was Test and interview. The results showed that based on the test results obtained: difficulties in the ability to interpret mathematical ideas rationally in writing, difficulties in mathematical problems into mathematical models and difficulties in the ability to express mathematical ideas in the form of descriptions. Meanwhile, based on the results of the interview, namely: (1) technical difficulties, and (2) student adaptation difficulties. To overcome these difficulties, it is necessary which is a combination of Online and Offline learning or also called blended learning.

The purpose of this study is to describe the mathematical communication skills of high school students in terms of guardian and idealist personality types. Subjects in this study were taken using a purposive random sampling technique of two students from class X senior high school in Bandar Lampung with different personality types, that is one student with guardian personality type and one student with a idealist personality type based on David Keirsey's personality dimensions, with personality type initial guardian (NAP) and initial idealist personality type (DBD). Mathematical communication skills are analyzed based on the following criteria : (1) the ability to write down what is known and asked about the questions; (2) the ability to write answers according to the purpose of the questions; (3) the ability to write down reasons for answering questions; (4) the ability to make mathematical terms and symbols; (5) the ability to make images that are relevant to the questions; (6) the ability to make conclusions in their own language. The results showed that subjects with guardian personality type were only able to master the five criteria of mathematical communication ability. The subject was unable to conclude with his own language. The results showed that subjects with idealist personality type were only able to master the five criteria of mathematical communication ability but the subject does not master the third criterian, the subject is unable to write down the reasons for answering the question.
