Abstract

Solving mathematical problems require knowledge and experiences to determine the right strategy. One of the efforts that can be used to encourage problem-solving skills is to develop reflective thinking. Reflective thinking can be a strategy to explore mathematical problem-solving abilities by questioning the answers or questioning the problems encountered so that new thoughts can be used to determine appropriate problem-solving strategies. Therefore, this study aims to explain the reflective thinking process carried out by prospective teachers in solving mathematical problems. This study used a qualitative research design with data collection through test and interview process as a triangulation stage. Participants in this study were 2 prospective teachers who carried out a reflective thinking process and were known through think aloud in implementing the test. The results showed that scaffolding was needed to complete the reflective thinking process in problem-solving. Two scaffolding positions appeared in the reflective thinking stage: (1) after the questioning and evaluating stages, scaffolding is needed as a bridge to the reasoning stage; (2) After the questioning stage, scaffolding is needed to bridge the evaluating and reasoning stages. In the reflective thinking process, scaffolding generates new knowledge to find the right problem-solving strategy.

Abstract

[English]: Some students might have the proper knowledge to use mathematical procedures where relevant, but do they actually have a solid understanding of “why or how” those procedures work?  Such an incomplete understanding of mathematics concepts can be a stumbling block in students’ success in mathematics. This paper aims to propose and elaborate a framework for developing proceptual knowledge combining both procedural and conceptual knowledge on differentiation that are constructed on existing mathematics learning theories on how we understand mathematics, besides my personal reflections from the independent learning on differentiation. The theoretical and practical perspectives proposed in this article share insight with anyone in developing a more meaningful mathematics-independent learning experience, especially on topics with complex mathematical formulas or procedures, such as differentiation. [Bahasa]: Sebagian siswa mungkin memiliki pengetahuan yang tepat dalam menggunakan prosedur matematika secara relevan, namun apakah mereka sungguh memiliki pemahaman yang utuh tentang "mengapa atau bagaimana" prosedur matematika tersebut diperoleh? Pemahaman yang tidak utuh tersebut berpotensi menjadi penghalang kesuksesan siswa dalam memahami konsep matematika. Artikel ini mengusulkan kerangka kerja untuk mengembangkan proceptual knowledge (pengetahuan proseptual) pada materi turunan, yakni kombinasi pengembangan pengetahuan prosedural dan konseptual matematika yang dibangun di atas teori-teori pembelajaran matematika yang ada, serta hasil refleksi pribadi penulis dari proses belajar mandiri tentang konsep rumus diferensial. Perspektif teoritis dan praktis yang diusulkan dalam artikel ini dapat menjadi panduan bagi siapa saja untuk mengembangkan pengalaman belajar matematika yang lebih bermakna, khususnya pada topik dengan rumus dan prosedur matematis yang kompleks seperti pada turunan.

Abstract

Mathematics learning must be facilitated by students' skills in conveying their creative ideas and the teacher's skills needed to provide constructive learning. One of the abilities that can develop students' thinking skills in learning geometry is spatial ability. Mathematical spatial ability pressure in the field of geometry and is important for students to master. The importance of spatial abilities requires students to have good mathematical spatial abilities. Because learning mathematics cannot be separated from geometry, so with good spatial abilities, mathematical abilities will also be good, especially in the field of geometry. The form of an effort to find out students understand geometry material is by using van Hiele's geometric thinking theory so that they are able to overcome students' difficulties in learning geometry. Van Hiele's stages consist of the visualization stage, the analysis stage, the abstraction stage, the deduction stage, and the rigor stage. ). In this study, we wanted to know the spatial abilities of students at the level of visualization (0) and analysis (1) from van Hiele's theory, namely students' initial ability to recognize geometric elements/components.

Abstract

School closures and home learning policy to prevent the spread of COVID-19 in Indonesia raised concerns about learning loss. This research was focused on examining the potential for learning loss in terms of the mathematical competence of year-3 indigenous primary school students in Indonesia due to school closures during the pandemic. This qualitative research with a phenomenological approach involved 8 year-3 students who had been studying from home for the last 1.5 years or so. Data collection was carried out using mathematical diagnostic tests and interviews. Results from this study revealed the phenomenon of learning loss in terms of the mathematical competence among the students, where the mastery of prior mathematics knowledge and skills required for grade 3 were not mastered yet. Also, their mathematical competences were below the competency standard in the curriculum for grade 3 primary school in Indonesia. The significancy of this study emphasized that the phenomenon of learning loss that occurred in primary school students during and even after the COVID-19 pandemic should be a serious concern for all parties and stakeholders. Hence, some solutions and quick steps that need to be taken to mitigate the long-term impacts of learning loss are also included in this article.

Abstract

School closures due to the COVID-19 pandemic have resulted in learning loss in primary school students, so a diagnosis of the students' numeracy skills is urgently needed at the beginning of learning to adapt learning to students' average ability levels (teaching at the right levels). This study aimed to develop a module that can assist and become a reference for teachers in schools in diagnosing and mapping students' numeracy abilities at the beginning of learning. Therefore, this research was carried out following the procedures of research and development (R&D). Prior to implementation, the developed module was validated by two experts (media and material experts) with validation results in “very good” categories for each aspect of the material, layout, and graphics. The results of the study based on the teacher's response questionnaire indicate that the module developed is very helpful for the teachers in mapping students' numeracy abilities at the beginning of learning after the COVID-19 pandemic and provides an alternative follow-up to the results of students' numeracy assessments. Thus, the developed module is suitable for use as a reference in conducting assessments regarding early primary school students’ numeracy.Keywords: diagnostic assessment module, early primary students, numeracy, post COVID-19 pandemic
