Abstract

Open-ended approach has a valuable impact in supporting students’ mathematical problem solving ability. This approach allows students’ to explore different ways in solving mathematical problems, not only focusing on one solution but also considering other alternatives. However, students inevitably make mistakes in solving the problems in their learning process. Therefore, it is important to analyze the errors made by students in mathematics learning using student worksheets with an open-ended approach. This research is a descriptive qualitative study conducted in 6 Private National Junior High Schools in Yogyakarta. These schools were randomly selected using a spinning wheel from 13 schools in the third quartile. The subjects of this study were 384 students selected from 12 classes out of 22 classes in all the research schools. Data were collected using a problem-solving ability test on the subject of systems of linear equations in two variables and interviews. Student errors were categorized based on Newman's Error Analysis, which includes: (1) reading errors, (2) comprehension errors, (3) transformation errors, (4) process skill errors, and (5) encoding errors. The results of this study show that the dominant error sequence made by students is process skill errors, reading errors, comprehension errors, transformation errors, and encoding errors. These errors are caused by students' inaccuracy in calculations, difficulties in calculations, errors in reading the questions, comprehension errors in understanding the given mathematical problems, errors in translating the information provided in the questions, and errors in concluding the problem-solving results due to students not understanding the question instructions properly, and the given mathematical problems being unfamiliar to the students         Keywords: student errors, student worksheet, open-ended approach, problem-solving skills.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp468-485

Abstract

This research aims to develop e-worksheet learning media with a STEM approach to improve junior high school students' creative thinking skills. This research is a development research using the ADDIE model. This research was conducted at 6 Catholic private junior high schools in seventh grade. The results of this study are e-worksheets that are made to meet valid, practical, and effective aspect categories. Valid aspects are obtained through the assessment of material experts and media experts with values of 77 and 63.5 and fall into the very good and good categories. The practicality aspect was obtained through small-scale tests and large-scale tests with values of 80.17 and 75.83 and were in the good category for both. The effectiveness aspect is obtained through the results of the effectiveness test which includes paired sample ttest, one sample t-test, and mean different test. Based on the paired sample t-test for the experimental class and the control class, the results showed that there was an increase in scores before using the e-worksheet and after using the e-worksheet. Based on the one sample t-test, it was found that there was an increase in students' creative thinking abilities by using eworksheets. The conclusion of this study is that e-worksheets with the STEM approach are effective for improving junior high school students' creative thinking abilities.    Keywords: ADDIE, creative thinking, e-worksheet, STEM. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1680-1691

Abstract

Pengabdian ini bertujuan untuk memperlengkapi guru melalui Pelatihan Pembelajaran Berbasis Proyek STEM untuk memperkuat Profil Pelajar Pancasila dalam kerangka Kurikulum Merdeka. Pengabdian ini dilakukan di SMA Katolik Yos Sudarso Karawang dengan membawakan topik STEM yaitu merancang sensor alarm gempa dalam pembuatan Smart City. Hasil dari kegiatan pengabdian ini adalah guru dapat menerapkan pembelajaran berbasis STEM pada pembuatan Smart City untuk memperkuat Profil Pelajar Pancasila dalam kerangka Kurikulum Merdeka. Dengan mengintegrasikan proyek ini, siswa terlibat dalam pembelajaran interdisipliner yang mendukung siswa mampu bernalar kritis, mandiri, gotong royong, dan kreatif. Pendekatan ini direkomendasikan sebagai strategi dalam pelaksanaan kurikulum guna mempersiapkan siswa menghadapi tantangan masa depan dan menanamkan nilai-nilai Pancasila.

Abstract

This research explored the effectiveness of the Project-Based Learning (PjBL) instructional model in improving critical and creative thinking skills among students at SMAK 1 Bina Bakti Bandung, Indonesia. Employing a one-group pretest-posttest quasi-experimental design, the research examined how students’ critical and creative thinking skills developed after participating in a series of PjBL learning activities in polynomial topic. The findings revealed significant improvements in both critical and creative thinking skills. Critical thinking showed notably increases in all indicators (analysis, synthesis, problem solving, inference, evaluation) with the most substantial changes in synthesis and problem solving. Likewise, creative thinking also showed a remarkable improvement in all indicators (flexibility, originality, elaboration, reflection, and fluency) particularly in elaboration and fluency. The effect sizes of critical and creative thinking were measured at 0.804 and 0.949 respectively, indicating the strong impact of PjBL in improving both domains. While critical thinking exhibited comparatively elevated scores both prior to and following the intervention, the extent of enhancement was more pronounced in creative thinking. It was suggested by these results that while a relatively strong foundation in critical thinking had already been demonstrated by the students, their creative thinking skills were particularly effectively enhanced by the implementation of PjBL.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi tingkat kecemasan matematika serta mengidentifikasi faktor-faktor penyebabnya pada mahasiswa baru program studi Pendidikan Guru Sekolah Dasar (PGSD) di Kampus Unesa 5. Penelitian ini menggunakan pendekatan kuantitatif-deskriptif dengan teknik total sampling, yang melibatkan seluruh mahasiswa baru PGSD tahun akademik 2024/2025 sebanyak 157 orang. Data dikumpulkan melalui angket skala Likert lima poin yang mencakup empat dimensi kecemasan (mood, motorik, kognitif, dan somatik), serta satu pertanyaan terbuka untuk mendalami persepsi mahasiswa. Hasil penelitian menunjukkan bahwa mayoritas mahasiswa (69,4%) berada pada kategori kecemasan matematika sedang, sementara 18,5% menunjukkan kecemasan tinggi. Determinan utama yang memengaruhi kecemasan meliputi pengalaman belajar negatif di masa lalu, ketidakpahaman konsep dasar, gaya mengajar dosen yang monoton, rendahnya kepercayaan diri, serta tekanan sosial dan akademik. Temuan ini menguatkan hipotesis bahwa kecemasan matematika di kalangan mahasiswa calon guru bersifat kompleks dan multidimensional, serta membutuhkan intervensi pedagogis yang empatik dan kontekstual.
