Abstract

Chemistry is one of the subjects that is abstract and emphasizes concepts. This is often the cause of low levels of student understanding (misconceptions). Not only because of inappropriate learning methods or models, but less in-depth question instruments also increase students' misconceptions. This study was conducted with the aim of analyzing the level of conceptual understanding of grade X students on the Periodic System of Elements (SPU) material which is basic material before other complex chemical materials. Misconception analysis was carried out using Rasch analysis from the results of the Three-Tier Multiple Choice Test (TTMCT) instrument. The method used is a quantitative method and expert validation was carried out by eight experts. The study was conducted in 5 schools (public-private). The results of the study showed that students' conceptual understanding was low and several misconceptions were found.

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 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.
