This study aims to analyze the difficulties of class VIII junior high school students in working on statistical problems through online learning. The method used in this research is descriptive qualitative research method, by giving a test in the form of a description consisting of 3 questions using Bloom's taxonomic thinking ability level. The subjects in this research were students in class VIII at SMPN 6 Cimahi, totaling 17 students. The data collection technique used in this study is in the form of test results with Bloom's taxonomic ability level. low-level abilities represent C3, C4 and C5 represent moderate-level thinking skills and C6 represent high-level thinking. The results of the interpretation of the difficulties that students face in solving statistical problems are C3 got a good interpretation, C4 and C5 with less interpretation. Difficulties that affect students in solving problems on statistical material are lack of understanding of concepts, completion steps, incomplete mastery of the material, and errors in calculations. In addition, during the current pandemic, there are other non-technical obstacles such as the difficulty of accessing the internet for students living in remote areas

ANALISIS KESULITAN SISWA SMP DALAM MENYELESAIKAN SOAL PERSAMAAN LINEAR DUA VARIABEL

Mathematics is a subject that has a very large role for the development of education in the current era. But in fact, it is still considered a difficult lesson to learn and not interesting because there are too many formulas to memorize. Where the reason for solving students' difficulties in completing the SPLDV material in junior high school is because it is easy to find in students' daily lives. The number of 20 students of class IX SMPN Satu Atap Karya Utama is the subject of the research. The research method uses descriptive qualitative, with instruments in it, namely test questions with specified indicators. The data analysis uses data reduction, data presentation, and drawing conclusions. After being studied, it was found that several students had problems with the SPLDV material story questions. Errors in student answers vary from the lack of students learning concepts from SPLDV, students are still confused in determining the right method to solve problems related to SPLDV, the next obstacle is the difficulty of students changing story questions into the process of mathematical modeling due to their lack of accuracy in reading questions related to the material. SPLDV

PENINGKATAN MOTIVASI DAN HASIL BELAJAR SISWA PADA MATERI BARISAN DAN DERET DENGAN METODE REWARD

This research is included in classroom action research or classroom action research to examine efforts to increase students' motivation and learning outcomes after being rewarded. The hypothesis is that the method of giving rewards can be one of the efforts to increase motivation, which impacts student learning outcomes in series and sequence material in distance or online learning in class XI SMK students. The research instrument for class XI RPL-A SMK Pusdikhubad Cimahi in the 2020/2021 period was 34 people. Researchers used an instrument with an ability test to measure student learning outcomes and a questionnaire to measure their learning motivation. The data analysis technique used is the initial data analysis or requirements test which consists of normality test, homogeneity test. Then the final data analysis was carried out in the form of normality, homogeneity, T-Testm, N-Gain, and Treatment tests. Researchers found an increase in learning motivation and learning outcomes for class XI SMK students in online or online learning in the subject "Barisan dan Deret." This is indicated by the percentage of students' motivation scores and learning outcomes in cycles I and II. Student learning motivation in cycles I and II, namely 2.92 and 4.22, means an average increase of 1.30. And for student learning outcomes in cycles I and II, namely 52.94% and 79.41%, which means there is an average increase of 26.49%
