Abstract. This research aims to determine the increase mathematical representation ability of students with cooperative learning base multiple intelligence. The lower mathematical representation ability and the difficulty in understanding trigonometry and also not facing multiple intelligences is the reason for this research. This research is a quasi experiment that compares two classes with different treatments, cooperative learning based on multiple intelligence and exspositori learning. Learning media in reasech is the RPP and LAS that is validated the expert team. The research instrument was also validated by an expert team and continued with validation, reliability, difficulty and differentiation tests. The analysis used is one-way ANOVA obtained by Fcount (4,342)> Ftable (0,05) (4,026) Explained, H0 is accepted, and it can be concluded that the increased ability of mathematical representation in multiple intelligence-based cooperative learning rather than increasing mathematical representation ability in ordinary learning.Keywords: mathematical representation, cooperative learning, multiple intelligence

This study was motivated by the transformation of the learning process from face-to-face to online learning due to the Covid-19 pandemic. This study aims to analyze students' online learning readiness in the Covid-19 pandemic era regarding statistics learning outcomes. This research is a quantitative descriptive study using a regression research design. Data collection was carried out by providing online learning readiness questionnaires and statistical material tests to students. Based on the results of data analysis, it was found that there was a relationship between online learning readiness and student learning outcomes statistics, with the acquisition price of Fcount = 4.195 and a significance value of 0.048 <0.05, and 46.1% of student statistics learning outcomes were influenced by learning readiness and the rest was influenced by external factors. student learning readiness. Based on these results, it is concluded that online learning readiness affects student learning outcomes statistics, where the large influence of learning readiness is 46.1%. Therefore, so that lecturers and students can maximize factors outside of learning readiness so that the achievements and objectives of the statistics course can be maximally achieved even though learning is carried out online.

In solving the problems they face, students must think so that they can apply the right concepts to the problems they face. This process can run effectively in learning if students have good reflective thinking skills. Mathematical reflective thinking is one of the thought processes needed in the process of solving mathematical problems. The purpose of this study was to determine the increase in reflective thinking skills between students who received learning with problem-based learning and conventional learning. The research method used is quantitative research with a quasi-experimental design. The population of this study was students of grade 7 MTs Islmaiyah Medan in the academic year 2019/2020. The sample in this study was students of class 7-A and 7-B MTs Islamiyah Medan. The data were collected by giving a reflective thinking ability test instrument. The data obtained were analyzed using a two-way ANOVA statistical test. Based on the research findings, it was found that there was an increase in students' reflective thinking skills taught by problem-based learning with students taught conventionally. Where the increase in reflective thinking skills between students whose learning process using problem-based learning is significantly higher than students whose learning is through conventional learning. Based on these results, it can be concluded that in an effort to foster students' mathematical abilities, the learning model used must match the characteristics of the learning model with mathematical abilities.

The purpose of this study was to determine whether the mathematical communication skills and attitudes of students who were taught with the Think-Talk-Write (TTW) strategy were better than conventional learning. This research is a quasi-experimental research which compares two learning models, namely the TTW cooperative learning model and the conventional learning model. This research was conducted on students of class VII SMPS Mentari Bangsa Medan, which consisted of 2 classes. This study involved two variables, namely the independent variable and the dependent variable. The independent variable is the TTW and KAM learning strategy, while the dependent variable is the mathematical communication skills and attitudes of students towards learning. The sample consist of 42 students for TTW strategy and 37 students for conventional learning. The conclusion is that students who get learning with the TTW strategy have significantly better mathematical communication skills than students who get conventional learning (tcount = 4,93 more than ttable =1,66) and the attitudes of students who get learning with the TTW strategy are significantly better than students who get conventional learning (tcount = 3,14 more than ttable = 1,66).
