Penelitian ini mengkaji hubungan antara penerapan model pembelajaran problem based learning dengan kemampuan literasi matematis siswa SMP. Penelitian ini didasari oleh rendahnya kemampuan literasi matematis siswa SMP pada umumnya, khususnya siswa SMPN 2 Sedong Kabupaten Cirebon. Hasil tes kemampuan awal literasi matematis yang dilakukan pada siswa SMP Negeri 2 Sedong pada kelas VII, VIII, dan IX menunjukkan bahwa, kemampuan literasi matematis pada siswa kelas VIII tergolong rendah. Metode penelitian yang digunakan dalam penelitian ini adalah metode survey dengan teknik korelasi. Metode ini digunakan untuk melihat seberapa kuat dan seberapa besar pengaruh model pembelajaran problem based learning terhadap literasi matematis siswa SMP. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 2 Sedong Kabupaten Cirebon Tahun Pelajaran 2018/2019, sampel penelitian diambil dengan teknik purposive sampling sebanyak 32 siswa kelas VIII SMP Negeri 2 Sedong Kabupaten Cirebon Tahun Pelajaran 2018/2019. Instrumen yang digunakan dalam penelitian ini adalah skala disposisi matematis dan lembar tes kemampuan literasi matematis. Hasil penelitian menunjukkan bahwa terdapat hubungan yang positif antara model pembelajaran problem based learning dengan kemampuan literasi matematis siswa SMP, serta model pembelajaran problem based learning memberikan pengaruh sebesar 37,8% terhadap kemampuan literasi matematis siswa SMP

The purpose of this study is to describe the students’ algebraic thinking skills and errors in solving algebraic problems on volume of cube material for class VIII of Junior High School. The research design used was in a form of the descriptive qualitative research method. This study captured the students’ algebraic thinking skill on two indicators, namely the students’ ability to represent problems in the relationship between variables and the students’ ability to perform operations on algebraic form. Based on the result of the categorization, three students from the high-level category were chosen as the subjects of this study. In depth interviews were given to the subjects of the study in order to explore the answers that they provide on the mathematic problems given. The findings revealed that the students with high-level of algebraic thinking skills could solve mathematics problem in algebraic form correctly especially in transformational activities. It was indicated by the students’ ability to provide a solution for algebraic equation problems. Meanwhile, the students’ error in solving the mathematical problems in a form of build-cube space was due to the students’ inaccuracy in writing the final results on the answer sheets for the algebraic thinking ability test. Overall, the students encountered several types of errors, those were the error in the procedural and technical/calculated on comparisons, the error in witing mathematical units, and lastly the error in substituting variables

This study aims to develop Youtube-based audio-visual learning media to improve students' mathematical concept understanding skills. Learning during the Covid-19 pandemic requires students to study online, resulting in a low ability to understand students' concepts, therefore alternative learning is needed. Youtube-based audio-visual learning media is an alternative learning that will facilitate students in online learning activities. The researcher uses the Research and Development (R&D) method with the ADDIE development model. The trial subjects in this development research were expert subjects, namely material experts and media experts, and the subjects of class VIII-B students of SMPN 3 Sindangwangi Satap. Determination of the subject using purposive sampling technique and data collection techniques using a questionnaire. The results showed that material expert validation got a 100% score percentage and media expert validation got a 90% score percentage so that it was included in the "Very Appropriate" or "Easy to use without revision" assessment criteria. The results of student responses get a percentage value of 93% so that it is included in the "Very Good" assessment criteria. So, this Youtube-based audio-visual learning media is suitable for students to use.

This thesis entitled an effort to improve students' understanding of mathematical concepts insolving problem solving through Polya. The purpose of this research is to know theimprovement of students' concept comprehension in solving the story problem through Polyaapproach. This research uses Classroom Action Research (PTK) which is implemented inClass VII A MTs PUI Cilimus Lesson Year 2017/2018. Adapaun source data used is theobservation of students to know the development of student activities during learning andtests to determine the improvement of students' concepts in understanding the problem. Theresulting data will be analyzed by descriptive method. The theoretical basis used is thetheory of concept comprehension, problem solving and Polya approach. Based on dataanalysis done, it can be concluded that by using Polya approach in solving problem solvingproblem there is increasing understanding of student concept. This is evident from the resultsof the test in the second cycle of 48% of the initial test is only 30% and in the final testreached 78%. While the concept of students understanding also increased by 22.5% fromcycle 1 of 75% and cycle 2 of 97.5%. Therefore, the method of Polya approach is suggestedto be used to improve the concept of students in solving the problem solving problem.Keywords: Conceptual understanding, problem solving, Polya approach

The research is based on the law of mathematics conceps understanding and the less of the students’s activation in learning process. The research is Quasi Experimental research. The research design is used Nonequivalent Control Group Design and sample collection technique is SamplingPurposive. The sample of the research is the 7th qraders39 student class 7th E is classes eksperimental and 39 student class 7th D is classes control. The population in the research is the students of class SMPN 2 Kapetakan Kabupaten Cirebon, academic year 2016/2017 The instrument used in the research is mathematics concept understanding skill test and student’s observation sheet. Test of the difference of the average of post-test using the test of Independent Sample T-Test equals sig (1-tailed) score 0,001< 0,05 means H0 ejjected. And then the difference of the average using of N-gain using the test of Independent Sample t-test equals sig score (1-tailed) 0,000 < 0,05 means H0 ejjected. And then the test of the difference of the average of self confident using the test of mann whitney U test sig (1-tailed) score 0,0005< 0,05 means H0 ejjected. The research result shows that: (1). The improvement of mathematics conceps understanding skill which is using realistic mathematic educationis better than the students who are learning by conventional learning process. (2). self confident in those students who are learning by mathematic realistic mathematic educationis better than the students who are learning by conventional learning process.
