Difficulty Index

This research aims to determine the quality of the questions used to measure students ' mathematical problem-solving skills. This type of research includes quantitative descriptive research. The research subject is a grade VII student with a primary data source is scores of mathematical problem-solving skills. The research instrument used was a written test to measure problem-solving abilities. The data analysis technique used is a quantitative analysis by looking at the validity, reliability, differentiation power, and bullet-grain index of the matter. The results showed that the problem has been valid, the reality belongs to the category quite well, the differentiator power for three items, including bad, enough, and good classes. Meanwhile, the difficulty index shows a number in the easy category, and two names are included in the medium category. Thus, it concluded that the instruments used to measure problem-solving abilities are valid and in a suitable category. It can see it from the instrument trial results with the percentage value of students' problem-solving abilities, which is included in the very high category, namely 20%. The number of students who have problem-solving skills in great variety could be presented at 53.33%. Students who have sufficient and low problem-solving abilities were given at 16.67% and 10%.Penelitian ini bertujuan untuk mengetahui kualitas butir soal yang digunakan untuk mengukur kemampuan pemecahan masalah matematika siswa. Jenis penelitian ini termasuk penelitian deskriptif kuantitatif. Subjek penelitian adalah siswa kelas VII dengan sumber data utama adalah skor kemampuan pemecahan masalah matematika.

Interesting Learning

AbstrakPembelajaran di abad 21 sangat memerlukan berbagai inovasi media pembelajaran yang dapat dijadikan sebagai alat bantu pendidik dalam melaksanakan kurikulum. Buku saku digital berbasis science, technology, engineering, and mathematics (STEM) bertujuan agar dapat dikembangkan menjadi media pembelajaran yang layak dan menarik terhadap kemampuan pemecahan masalah. Metode penelitian yang digunakan adalah Reseach and Depelovment (R&D) dengan menggunakan model ADDIE. Teknik analisis data menggunakan teknik deskriptif kualitatif serta kuantitatif. Proses uji coba dilakukan setelah validasi ahli materi dan ahli media yang menunjukkan bahwa buku saku berbasis STEM memiliki kriteria menarik untuk digunakan. Namun uji efektivitas media pembelajaran buku saku digital tidak dapat terlaksana disebabkan adanya pandemi covid-19 yang mengakibatkan kegiatan pembelajaran dilakukan secara daring atau online. Adanya kebijakan tersebut mengakibatkan penelitian ini hanya terlaksana sampai pada tahap development atau pengembangan. STEM-Based Digital Pocketbook: Development of Learning Media on Students' Mathematical Problem-Solving Skills AbstractThe 21st century needs a variety of learning media innovations that can be used as a device in implementing the curriculum. The goal of digital pocketbooks based on science, technology, engineering, and mathematics (STEM) is to develop into worthy and interesting learning media on mathematical problem-solving skills. The research method used Research and Development (R&D) using the ADDIE model. Data analysis techniques use qualitative and quantitative descriptive techniques. The process was conducted after validation of material experts and media experts who showed that STEM-based pocketbooks had interesting criteria to use. However, the effectiveness of digital pocketbook learning media cannot be carried out due to the covid-19 pandemic that resulted in learning activities being conducted online or online. The existence of this policy resulted in this research only being carried out to the stage of development or development.

Load Theory

The background of the research is based on the fact that problem solving skills and its process is still low so that those create overload information. Another way to overcome this problem is to use a problem-based learning model which concerns on cognitive load theory. This study is aimed to determine on how students' problem solving skills when using a problem-based learning model modified by cognitive load theory. This research method uses a combination of research methods, namely quantitative as primary data and qualitative as secondary data. The population in this study are all students of grade VII Junior High School accredited A in Tangerang Regency. The sampling technique used is cluster random sampling and the selected sample is 60 students of Grade VII SMP Negeri 3 Cikupa which divided into experimental class and control class. The instruments in this research are 5 short essay tests and non-tests, questionnaire and interview. Based on data analysis’ result, it can be concluded that the achievement and improvement of students' mathematical problem solving abilities which use problem-based learning model modified by cognitive load theory is better than for those using problem-based learning generally.

Classification of personality based on the MBTI personality grouped by David Keisey. The purpose of this study was to determine the differences in students' mathematical problem solving abilities in terms of guardian and idealistic personality types in SMA Negeri 4 vocational youth. This research is a qualitative research. The subjects of this study were 4 students from class X Mia 3 SMA Negeri 4. The data validity technique used in this research is triangulation technique. Data analysis techniques include, descriptive data of written test results and interview results, analyzed from written test results and interview results, then conclusions are drawn. The results of the discussion can be concluded that there are differences in mathematical problem solving abilities of guardian and idealist personality types. Guardian personality type subjects can fulfill all problem solving indicators according to polya, namely the stages of understanding the problem, planning solutions, solving problems, and re-examining and drawing conclusions properly and correctly, while subjects with idealistic personality types at the stage of understanding the problem do not write down what is asked. In the problem-solving stage there are errors so that the results obtained are wrong and do not meet one of the polya indicators, namely not re-examining the existing answers but can draw conclusions. So the researchers suggest that students can improve their mathematical problem solving skills well

This study aims to determine whether the improvement of students' mathematical problem solving skills that get the learning of Model-Eliciting Activities is better than students who get regular learning. Method in this research is experiment and research design pretest and postest in experiment and control class. The population in this study were all students of MTs Kota Cimahi. School samples were taken at random, and obtained by MTs Negeri Kota Cimahi. Then the sample is selected two class VIII at random class. The experimental class uses Model-Eliciting Activities, while the control class uses ordinary learning. The hypothesis in this research is the improvement of student solving abilities of MTs students in Cimahi whose learning using Model-Eliciting Activities is better than using ordinary learning. Research data obtained through the instrument of posttest mathematical problem solving ability. The posttest data is processed by normality test, homogeneity test, and two average difference test using SPSS (Statistical Product and Service Solution) software version 16.0 for Windows. The results showed that the improvement of problem solving ability of MTs students in Cimahi whose learning using Model-Eliciting Activities was better than those using ordinary learning.

This study aims to develop a mathematics handout based on local wisdom nuanced to increase the mathematical problem-solving skill of the Secondary students. This research is motivated by the student’s ability to solve the social arithmetic problem. This study used four phases of developmental research such as Investigation, Design, Realization, and Test, Evaluation, and Revision. The characteristics of local wisdom were acquired within the design or context in the mathematics handout to develop secondary students problem-solving skills. The results show that the students do the stages of problem-solving by Polya, get the maximum score and show students’ positive responses in the questionnaire given. Therefore, it met the proper handout criteria such as valid, practice, and effective. In the future studies, we encouraged to develop learning materials which have a guide to do phases of problem-solving and apply the way to solve some problems in mathematics.
