This study addresses first graders' conceptual knowledge exhibited in addition strategies in relation to instructional practices and teachers' beliefs in a suburban Alabama school. To address the purpose of the study, the central question was "What is the nature of the relationship between curricular practices and beliefs and students'…

Students with emotional and behavioral disabilities (EBD) typically struggle with instruction in regular classrooms/schools. The problem peaks in secondary schools where students with EBD have some of the highest dropout rates when compared to their peers in other disability categories (Bradley et al., 2008). Universal Design for Learning (UDL) is…

It has become increasingly clear that the early use of decomposition for addition is associated with later mathematical achievement. This study examined how younger children execute a base-10 decomposition strategy to solve complex arithmetic (e.g. two-digit addition). 24 addition problems in two modalities (WA: Written Arithmetic; OA: Oral…

Cross-age studies have suggested that although children's notions of scientific phenomena change moderately with increasing age, certain misconceptions persist from preschool to a higher educational level. The purpose of this study was to diagnose the prevalence of selected misconceptions about the particulate nature of matter among preservice…

To improve understanding of identities and inverses, and to provide a stronger foundation for future mathematics, Sandra Miles designed a two-part lesson that makes the relationship between identities and inverses explicit. This article illustrates Miles' teaching of the first part of the lesson, focused on addition and subtraction, and then gives…

The aim of this research is to advance in the teaching-learning process of representing quadratic functions, both with pencil and paper and with a technological tool. For this purpose, a didactic experience is presented. Firstly, it is explained in the traditional way how to graph a quadratic function; secondly, students are introduced to the…

Metacognition is theorized to play a central role in children's mathematics learning. The primary goal of the current study was to provide experimental evidence in support of this role with elementary school students learning about mathematical equivalence. The final sample included 135 children (59 first graders and 76 second graders) who…

This research investigates students' learning about the electron transport chain (ETC) process in photosynthesis by watching a video followed by playing a serious board game--"Electron Chute"--that models ETC. The learning objectives targeted enriching a mental model that students could use to explain the causal relationship of the ETC…

This article describes an innovative intervention used within a professional learning experience (PLE) for early-career high school science teachers. The intervention aimed to develop participants' conceptual understanding of climate change while supporting engagement in learning via scientific practices through use of epistemic instructional…

Young children increasingly interact with technological devices, either as a form of entertainment or for educational purposes. This research sought to investigate the early symbolic understanding of an interactive, three-dimensional digital image presented on a tablet. Two studies were designed in which the children had to use the image as a…

In this practitioner inquiry, instructors in a teacher preparation program at a research-intensive university address their instructional effectiveness and improvement of student learning outcomes in a Single Course in Multicultural Education (SCME). As part of the inquiry, they conducted a comprehensive literature review of SCMEs. They used the…

Dealing with students' conceptions is one of the central elements of student-oriented teaching. To be able to organize learning processes efficiently, it is necessary to look at the learners in a differentiated way and to approach their conceptions individually. The first necessary step is the individual diagnosis of each student's conceptions.…

Gene technologies are developing at a high speed. Yet, the understandings and ethical conceptions about these developments are not sufficiently scrutinized and reflected. Our qualitative analysis examines everyday myths of younger generations about genome editing; these contribute to a complex fabric of rationally and intuitively justified…

There is a growing interest in conducting research in educational mathematics in the area of the didactics of probability, where the main difficulties that students have in understanding the concepts related to statistical inference have been revealed. For this research, the concept of the empirical rule and a practical application created by…

Teachers' professional noticing has been described as transitioning from descriptions of general pedagogy to analysis of students' mathematical procedures and conceptual reasoning. Such a shift is described as a transition towards more student-centered noticing. In the present study, we used screen recordings of pre-service teachers' (PSTs) 360…
