Analytical thinking is a skill to unite the initial process, plan solutions, produce solutions, and conclude something to produce conclusions or correct answers. This research aims to 1) determine whether there are differences in students' mathematical, analytical thinking skills between classes that use the Open-ended learning method and classes that use the lecturing method, 2) to find out whether there are mathematical, analytical thinking skills differences between students with high, moderate, and low self-awareness criteria, and 3) to find out whether there is an interaction between Open-ended learning method and self-awareness toward students' mathematical-analytical thinking skills. This research employs a quasi-experimental design. Based on the data and data analysis, this research is mixed-method research, and the design used in this research is the posttest control group design. This research was conducted on students who have studied the Real Analysis Courses. Based on the results of hypothesis testing, it was found out that, first, there are differences in students' mathematical-analytical thinking skills between the class that uses the Open-ended learning method and the class that uses the lecturing method. Second, there are mathematical-analytical thinking skills differences between high, moderate, and low self-awareness criteria. Third, there is no interaction between the Open-ended learning method with self-awareness of students' mathematical-analytical thinking skills.

Penelitian ini bertujuan untuk mengetahui kemampuan pemahaman konsep dan kemampuan komunikasi matematis peserta didik SMA di Pesawaran setelah diberi perlakuan pembelajaran Children Learning in Science (CLIS) berbantuan alat peraga edukatif. Metode penelitian ini menggunakan metode quasy experimental design. Subjek penelitian terdiri dari 152 peserta didik kelas XI SMAN 1 Negerikaton dengan 60 peserta didik sebagai sampel penelitian. Teknik analisis data menggunakan uji normalitas, uji homogenitas dengan uji hipotesis statistik yaitu menggunakan uji One-Way Multivariate Analysis of Variance (MANOVA). Dari data yang diperoleh nilai sig 0,00 ˂ 0,05 maka menunjukan nilai rata-rata bahwa terdapat pengaruh model pembelajaran CLIS berbantuan alat peraga edukatif terhadap kemampuan pemahaman konsep dan kemampuan komunikasi matematis dibandingkan model pembelajaran konvensional yang diterapkan oleh pendidik disekolah. Kesimpulannya adalah terdapat hasil yang positif terhadap model pembelajaran tersebut.

This study aimed to determine the effect of the NHT (Numbered Head Together) cooperative learning model on mathematical problem-solving abilities in terms of students' mathematical prior knowledge. The researchers employed quasi-experimental research and collected the mathematical problem-solving data using a description test. At the same time, the researchers investigated studentsâ€™ mathematical prior knowledge using the mid-semester examination (UTS) scores. The hypothesis was tested using the two-way ANOVA with unequal cells. The results showed that the NHT learning model provided better problem-solving skills than the direct learning model. The category of students' prior knowledge also affected their mathematical problem-solving abilities. Therefore, teachers should pay attention to the prior knowledge possessed by students so that an appropriate learning model can be selected.

The purpose of this research is to determine the effect of the Round Club Type of Cooperative Learning model on mathematical communication skills in terms of linguistic intelligence. This research is a type of Quasy Experimental Design research with a factorial research design. The population in this research were all 7th grade students of SMP Karya Bhakti Panaragan Tulang Bawang Barat. The sampling technique used is the Cluster Random Sampling technique with The Operation of Algebraic Form material. The sample consisted of two classes, namely the experimental class and the control class. Techniques in data collection used were mathematical communication skills tests and student linguistic intelligence questionnaires. The analytical technique used in this research is a two-way analysis of variance with unequal cells. Based on theoretical studies and calculations, it can be concluded that: there is an effect on students who use the Round Club type of cooperative learning model on mathematical communication skills, there is an influence of linguistic intelligence on mathematical communication skills, and there is no interaction between the Round Club type of Cooperative learning model and linguistic intelligence on mathematical communication skills.

This research aims to describe students’ mathematical representation skills in solving numeracy problem with profession context. This is qualitative descriptive research with 12 students for its research subjects. There are four steps in analyzing the data, those are data collection, data condensation, data display, and conclusions. To check the validity, researchers used techniques triangulation. This research shows that, among those 12 subjects, there are four types of model in solving numeracy problem with profession context. Those are first, students use visual and external representation; second, they perform visual, verbal, math model, and internal representation; third, they use verbal, visual, and external representation; and fourth of all, they use verbal and external representation. To make this result fruitfull, other researchers can try to design mathematics learning activities to train students’ mathematical representation skill such that when students solve numeracy problems, they will not face any difficulties.

This study aims to improve students High Order Thinking Skills through the application of the Group to Group Exchange learning model. The research method used is a quasi-experimental model with a Pretest-Posttest Control Group research design and a sampling technique using Cluster Random Sampling. The results showed that based on the research results obtained during the study, the average N-Gain Score for the experimental group using the Group to Group Exchange learning model was 59% with a minimum N-Gain Score of 51% and a maximum of 67%. While the average N-Gain Score control group with the Direct Instruction learning model is 39% with a minimum N-Gain Score of 34% and a maximum of 45%. This means that the Group to Group Exchange (GTGE) learning model is quite effective compared to the Direct Instruction (DI) learning model to improve students High Order Thinking Skill (HOTS).
