The effect of STEM-based (Science, Technology, Engineering, and Mathematics) learning model toward the students’ mathematical problem-solving ability in SD Muhammadiyah Condongcatur, Yogyakarta

This is a case study investigating a primary teacher’s beliefs, knowledge, and teaching practice in mathematical problem solving. Data was collected through interview of one primary teacher regarding his beliefs on the nature of mathematics, mathematics teaching, and mathematics learning as well as knowledge about content and pedagogy of problem solving. His teaching practice was also observed which focused on the way he helped his students solve several different mathematics problems in class based on Polya’s problemsolving process: understand the problem, devising a plan, carrying out the plan, and looking back. Findings of this study point out that while the teacher’s beliefs, which are closely related to his problem solving view, are consistent with his knowledge of problem solving, there is a gap between such beliefs and knowledge around his teaching practice. The gap appeared primarily around the directive teaching which corresponds to instrumental view he held in most of Polya’s process during his teaching practice, which is not consistent with beliefs and knowledge he professed during the interview. Some possible causes related to several associate factors such as immediate classroom situation and teaching practice experience are discussed to explain such inconsistency. The results of this study are encouraging, however, further studies still need to be conducted.

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.

AbstrakPentingnya kemampuan pemecahan masalah dalam pembelajaran matematika belum diikuti dengan pencapaian yang baik. Penelitian ini bertujuan menerapkan model pembelajaran Problem Solving dan Problem Posing serta menguji ada tidaknya perbedaan kemampuan pemecahan masalah dari kedua model tersebut. Penelitian dilaksanakan pada kelas X salah satu SMA Negeri di Salatiga dengan materi trigonometri. Sampel sebanyak 53 siswa, terbagi dalam dua kelompok eksperimen. Penelitian ekperimen semu ini menggunakan desain randomaized control group pretest-postest design, dengan instrumen berbentuk tes kemampuan pemecahan masalah dan lembar observasi. Analisis data menggunakan kovariansi pada taraf signifikan 𝛼 = 5% dengan kemampuan awal sebagai variabel kovarian. Hasil uji hipotesis menyimpulkan bahwa dengan mengontrol kemampuan awal siswa didapat bahwa siswa yang melaksanakan model pembelajaran Problem Posing secara signifikan memiliki kemampuan pemecahan masalah matematika yang lebih baik dibandingkan siswa yang melaksanakan model pembelajaran Problem Solving. Hasil ini menunjukkan pembelajaran hendaknya tidak hanya melatih siswa menyelesaikan masalah tetapi juga mengkonstruksi permasalahan. Differences in problem-solving abilities from the application of problem-solving and problem-posing in high school studentsAbstractThe importance of problem-solving abilities in mathematics learning has not been automatically followed by good achievement. This study aims to apply Problem Solving and Problem Posing learning models and to test whether there are differences in the problem-solving abilities of the two learning models. This research was conducted in class X mathematics learning at one of the public high schools in Salatiga on Trigonometry material. This quasi-experimental study used a randomized control group pretest-posttest design, with instruments in the form of problem-solving ability tests and observation sheets. The data analysis used was the covariance test at the significant level α = 5% with the initial ability as a covariate variable. The results of hypothesis testing with covariance analysis concluded that by controlling students' initial abilities it was found that there were significant differences in mathematical problem-solving abilities between the application of the two models. Students who carry out the Problem Posing learning model significantly have better mathematical problem-solving abilities than students who carry out the Problem-Solving learning model. These results indicate that learning should not only train students to solve problems but also construct problems.
