This paper examines Grade 10 students' conceptions of proof in a secondary school in Singapore. Using a purposive survey of 9 mathematical items, proofs by 8 students for two items, one on Number and Algebra and another on Geometry and Trigonometry, were coded using Harel's proof schemes. The findings show that the students' proofs for the two…

A central objective of science education is to foster a profound comprehension of fundamental scientific principles among students. Research has shown that a highly integrated knowledge structure is a key factor in achieving a deep understanding. This research has developed a friction force conceptual framework to model students' different…

In this paper the potentiality of meaning generation in a constructionist environment through an interplay between problem solving and problem posing is examined. The meaning-making process is examined by following how a Grade-10 student is engaged in an iterative cycle of reformulating and solving the initial problem within a Logo-based…

Incorporating open-ended real-world tasks enhances students' access to mathematical and real-life knowledge and maximizes learning experiences. This article examines how a secondary mathematics teacher used an open-ended problem on distributing pay raises to teach mathematical concepts and fairness to students. The teacher's actions exemplify…

Local wisdom in the use of medicinal plants is still not understood by students' potential. This study aims to develop student worksheets ("LKPD") on biodiversity of medicinal plants of the tidung tribe for class X students at SMA Negeri 3 Nunukan Regency. The research method used is Research and Development (R&D) with the ADDIE…

Quadratics provide a foundational context for making sense of many important algebraic concepts, such as variables and parameters, nonlinear rates of change, and views of function. Yet researchers have highlighted students' difficulties in connecting such concepts. This in-depth qualitative study with two pairs of Year 10 (15 or 16-year-old)…

The aim of this study was to determine the cognitive structures of high school students related to the atmosphere and climate. The study group consists of 70 students in the 10th grade of a state high school affiliated to Konya Provincial Ministry of National Education. In this study, a survey model, which allowed us to determine the current…

Background/purpose: This study aimed to measure the level of scientific concepts acquisition among basic-stage students in light of their teachers' use of artificial intelligence (AI) applications. Materials/methods: A scientific concepts acquisition test was developed to collect data. The study sample consisted of 396 tenth-grade students,…

The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

The study investigated the impact of guided inquiry-based laboratory experiments enriched instructional (GIBLEI) approach on conceptual understanding of tenth grade students in biology. The study included two purposively chosen schools and used a quasi-experimental design with non-equivalent groups. A class was randomly assigned as the…

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology…

Design-based learning is considered a powerful way to help students apply and develop understanding of science concepts, but research has shown that the success of this approach is not a given. Examining students' understanding of science concepts in various design-based learning contexts has thus continued to be an important field of research. To…

One of the efforts to improve the quality of education in Indonesia is through learning by integrating environmental culture. Environmental culture can be packaged in more meaningful learning through biological literacy. This study aims to assess the biological literacy skills of high school students using local potential-based biodiversity…

The combined use of origami and dynamic geometry software has recently appeared in mathematics education to enrich students' geometric thinking. The objective of this research is to study the roles played by the interaction of two artifacts, paper folding and GeoGebra, in a construction-proving problem as well as its generalization in the…

This study investigates the interplay between student reasoning and instructional strategies in trigonometry education. A qualitative case study was conducted to examine how Grade 10 students employ various reasoning approaches -- deductive, inductive, abductive, analogical, and algorithmic -- when solving trigonometry problems. Each approach…
