In a classroom environment where students are encouraged to talk and share their thinking about mathematics, it comes as no surprise to find an abundance of ideas flooding the room. Yet, what does one do with all these ideas? How do teachers and students use these ideas as they learn in the classroom? Moreover, how do teachers and students manage…

Whole number computations are a critical skill that serves as a foundation upon which higher-order concepts in mathematics are taught to children. To facilitate their instruction, educators often use multiple representations to support a child's cognition. Representations with physical manipulatives are widely studied through a graduated…

This paper reports on the development of a lecturer's conceptions of teaching through formal training and explores how evolving conceptions of teaching impact on their plans and practices in teaching. In this study, lecturers who are participants in the University of London Postgraduate Certificate in Higher Education (PGCertHE) wrote narratives…

Few digital product development tools are used in industry and academia compared to their historic paper-based counterparts. This is surprising as many parts of the product development process have digitised such as communication and Computer-Aided Design. Therefore, a gap in knowledge was identified which informed the development of a novel…

This paper demonstrated how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. Using a data-driven approach, we examined 1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance (i.e. posttest math knowledge scores) prediction and 2)…

In common with many other countries, the Iranian science curriculum does not introduce primary children to atoms and molecules but instead leaves the teaching of these concepts until high school. This paper challenges this practice and describes the changes in elementary Iranian children's understanding of atoms and molecules following a 10-h…

This study investigated to what extent and how novice second-language (L2) Spanish learners use the cognitive linguistics-informed concept of boundedness to support their development of aspect--namely, the Spanish preterite and imperfect. The concept was presented within the framework of concept-based instruction (CBI) as part of a regular,…

This study presents an analysis of the incommensurability about the representations or models elaborated by children from an Indigenous community within three areas or cultural domains, namely, the ethnic, daily (domestic), and school domains and their implications in relation to science education. The children belong to an Indigenous Nahuatl…

We build on mathematicians' descriptions of their work and conceptualize mathematics as an aesthetic endeavor. Invoking the anthropological meaning of practice, we claim that mathematical aesthetic practices shape meanings of and appreciation (or distaste) for particular manifestations of mathematics. To see learners' spontaneous mathematical…

Inspired by the approach first employed by C.S. Holling in his classic "disc experiment," this article provides a sequence of learning activities that increase students' understanding of the mechanisms behind saturating effects in predator-prey scenarios. The proposed lesson is recommended for inclusion in courses that address…

The present work describes a simple hands-on experiment kit for colorimetric quantification of ferric (III) ion (Fe[superscript 3+]) in an aqueous medium using anthocyanin extracted from "Ruellia tuberosa" L. as a green indicator. The extraction of a high amount of anthocyanin was easily accomplished by using only hot water instead of an…

The Brain-Based Teaching Approach is a strategy that implements methods from a brain-based learning (BBL) model. This approach was designed to be compatible with the inclinations and optimal functions of the individual brain to ensure that students can learn effectively. The module uses the Brain-Based Teaching Approach integrated with GeoGebra…

This paper analyses data from the Swedish sample of the international VASI (Views about scientific inquiry) study (Lederman et al. [2019]. An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline. "Journal of Research in Science Teaching." Published…

Informal learning environments such as Natural History Museums can introduce visitors to a variety of topics in evolution by providing accessible representations of concepts like geological time, evolutionary mechanisms, biological diversity, geological time, and fossil dating. Our study examined sixth-grade students' conceptualization of…

The development of modeling skills in mathematics is essential for individuals to understand, describe, control, and predict phenomena around them. This article describes the results of an investigation to find out how an activity -- based on a Models and Modeling Perspective -- stimulates the mathematics modeling skills of undergraduate students…
