Abstract: The aim of the research was to determine the effect of learning methods on mathematics achievement viewed from the student intelligence level. The learning methods compared were problem posing with CTL approach, problem posing and conventional. The type of the research was quasi experimental research. The population was all of students in the seventh grade of Junior High School in Purworejo in the academic year of 2012/2013. The sample of this research was taken by using stratified cluster random sampling. The sample was consisted of 177 students with 90 students in the first experiment class, 95 students in the second experiment class, and 92 students in the control class. The data ofÂ the research were gathered through documentation and test. The result of research showed that: (1) studentsâ learning achivement by using problem posing learning method with CTL approach was better than studentsâ learning achivement by using problem posing method and conventional learning, and studentsâ learning achivement by problem posing learning method was same as conventional learning method, (2) mathematics achievement of students with high intelligence level was better than that of students with medium and low intelligence level, and mathematics achievement of students with medium intelligence level was better than that of students with low intelligence level, (3) in learning by using problem posing learning method with CTL approach, the level of intelligence had the same effect in studentsâ learning achievement, in learning by using problem posing method, students with high intelligence level had performance as good as the students with medium intelligence level and were better than the students with low intelligence level, in learning by using conventional learning, students with high intelligence level had better learning achivement than students with medium intelligence level and low intelligence level, and learning achievement of students with medium intelligence level was the same as students with low intelligence level, (4) at the level of studentsâ intelligence with high, medium and low, problem posing learning method with CTL approach, problem posing learning method and conventional method produced the same effect in learning achievement.

The design of HOTS Ethnic-Mathematics is the stage that has been intended in this study. This type of research is research and development (Research and Development) by producing results in the form of Mathematics Higher Order Thinking Skill (HOTS) questions based on culture and local wisdom (Ethnic-Math HOTS). The development model referred to by the researcher is the Analysis, Design, Development, Implementation and Evaluation (ADDIE) which is adapted into Analysis, Design, and Development (ADD). The conclusion of this paper is Mathematical problem designs that are integrated with local culture and local wisdom can be developed into questions that have a function to measure students' high-level abilities. High-level abilities that can be measured using these questions are analytical skills, evaluation skills and creative abilities. By completing questions related to the culture in the area around students, students will be more challenged and motivated to do it. In addition, it will increase students' knowledge about the local culture in the area.

Masih rendahnya kemampuan pemecahan masalah siswa dalam memecahkan masalah khususnya soal matematika perlu menjadi perhatian bagi semua. Penelitian ini bertujuan untuk menghasilkan desain LKS digital berbasis STEAM untuk mengembangkan kemampuan pemecahan masalah siswa. Metode penelitian yang digunakan yaitu penelitian R&D dengan model pengembangan ADDIE yang terbatas pada tahap perancangan (design). Proses desain dari LKS ini melalui dua tahapan yaitu analisis (analyze) meliputi (1) analisis kebutuhan, (2) analisis karakteristik siswa, (3) analisis kurikulum bertujuan untuk mengetahui kemampuan siswa, mengetahui batasan materi, dan juga perlu tidaknya pengembangan LKS ini dilakukan. Tahap kedua yaitu perancangan (design), peneliti mendesain LKS digital setelah dilakukan peta penyusunan LKS, penyusunan desain isi LKS, dan juga pengumpulan referensi. Hasil dari perancangan (design) ini adalah desain penyajian soal pemecahan masalah berupa tema permasalahan yang memuat konsep matematika dengan tahapan proses pemecahan masalah menggunakan pendekatan STEAM bertujuan memenuhi indikator pemecahan masalah.

ABSTRACT This study discusses how to improve students' abilities after using a problem-based learning model in mathematics learning material. This type of research is quantitative research. Quantitative research consists of experimental methods and survey methods. In this study using the experimental method. The experimental method used to find interaction. The research design used was a quasi-experimental design with class 2 research taken from class VIII SMP in one of the cities of Sukabumi. The research sample used cluster random sampling technique. The research design used in this study was the design of the pretest-posttest control group. The instrument used in this study is essay questions as many as 6 items which have been declared valid and reliable. Based on the prerequisite test of the data produced by the research data, it is not normally distributed so that further testing is carried out, namely the mann-withney test. From the data analysis, the average posttest value of the experimental students with the problem based learning learning model was 18,24 and the average score of the posttest control class students without using the problem based learning learning model was 15,17. There is a significant difference in student learning outcomes, this is evidenced by the mann-withney test so this study rejects H0 and accepts H1. Thus, it can be concluded that there is an increase in learning outcomes in mathematical punishment abilities of students who use learning by using problem-based learning models on the material to get a flat side space.
