Background: Bringing about conceptual change in school science classrooms is difficult for teachers. Researchers in this field have struggled to influence classroom practice. Purpose: The present research presents a method and a framework for video-based pedagogy analysis. Sample: Six groups of 11-year-old pupils took part (three girls and three…

Isomorphism and homomorphism appear throughout abstract algebra, yet how algebraists characterize these concepts, especially homomorphism, remains understudied. Based on interviews with nine research-active mathematicians, we highlight new sameness-based conceptual metaphors and three new clusters of metaphors: sameness/formal definition, changing…

Research indicates that the early years are a pivotal time for developing foundational mathematical knowledge, and that early experiences with mathematics have a lasting impact on later numeracy skills and academic achievement. However, the importance of early mathematical thinking and learning is often undervalued or overlooked in early childhood…

The purpose of this study is to examine who young children (3-7-year-olds) would depend on for asking information, and whose information they would endorse: the one provided precise expressions which were the mathematical presentation of several measurements or the other by a person who provided relative expressions which were assistant's personal…

During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

In order to ensure the use, protection and sustainability of water, which is becoming more and more important for life, individuals need to develop their water literacy starting from the pre-school period. In this direction, it was aimed to improve the water literacy of 60-72 month old children who were in preschool education with online…

Many primary school students have difficulties understanding mathematical equivalence with considerably poorer performance in some countries than in others. However, students' formal understanding of equivalence has significant and long-lasting effects, as it predicts arithmetic and algebra achievement throughout school years. Currently, little is…

The efforts shown in recent years related to the reform movements in science education have focused on the assertion that informed nature of science understandings (NOS, hereafter) should be developed. In line with this idea, NOS has become the central component of numerous science curricula. In the study, therefore, it was aimed to determine…

The purpose of this systematic review was to examine the effectiveness of proportional reasoning interventions for students with learning disabilities (LD) or mathematics difficulty (MD). We evaluated fifth to ninth grade interventions on proportional reasoning content, instructional features, and disability and difficulty identification. The nine…

Exams constitute the predominant form of summative assessment in undergraduate biology education, with the assumption that exam performance should reflect student conceptual understanding. Previous work highlights multiple examples in which students can answer exam problems correctly without the corresponding conceptual understanding. This…

In this article, an adaptation of a secondary school mathematics comics-based instructional package for primary school mathematics classroom, and the teachers' and students' perceptions about the use of comics in the classroom are discussed. Further suggestions by the teachers on fine-tuning the package are also discussed.

This paper reports on a teaching experiment on mathematical modelling in an upper secondary school class that investigates how the constructs of "model eliciting" and "emergent modelling" may be brought together to inform teaching and learning. A prominent role is covered by the process of task design, seen as a complex process…

Despite the introduction of Common Core State Standards and the National Council of Teachers of Mathematics urging educators to explore fundamental concepts in mathematics at a deeper level, the majority of mathematics education has remained aimed at initial skill acquisition. The result has led to students learning to mimic a standard set of…

Learning mathematical concepts and procedures typically requires extended cognitive effort, presenting a challenge for many children. People can make tracing actions with the index finger, as well as mimic another's movements, with little or no conscious effort. From the perspective of cognitive load theory, such biologically primary actions may…

Building reasonable scientific arguments is a fundamental skill students need to participate in scientific discussions. In organic chemistry, students' argumentation and reasoning skills on reaction mechanisms are described as indicators of success. However, students often experience challenges with how to structure their arguments, use scientific…
