3D geometry is an essential concept in mathematics because it relates to real-world experiences and numerous mathematical topics. However, some students still have difficulty understanding this geometry. Therefore, this study aims to identify and describe students' epistemological obstacles to the dimensions of representation, spatial structure,…

This design-based research investigated the context and impact of a three-year practice-based professional development (PD) project introducing science teachers to pedagogical shifts required for full implementation and synergy among disciplinary literacy components of "Next Generation Science Standards" and "Common Core State…

This study examined students' views on geometry teaching via three-dimensional dynamic geometry software Cabri 3D. Teaching designed with Cabri 3D for solids volume measurement was implemented for 16 students in the eighth grade from a public secondary school in Turkey. The data obtained from the interviews with the students about the teaching,…

Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

This paper examines Grade 6 students' thinking about geometrical solids and their properties in the context of a computer-based task. The main focus is to explore how students interact with a number of tasks based on the dynamic transformation of computer-based representations of 3D solids in a geometry classroom with the aid of a Dynamic…

The purpose of this study was to develop a 3D virtual reality environment and to examine its effectiveness in order to facilitate the adaptation and integration of immigrant students into school. In the study, which was carried out in two stages, the design-based research method and the mixed research method were used, respectively. In the study…

While augmented reality (AR) technology has shown the potential to facilitate students' hands-on activities, few studies have explored its effectiveness in acoustic topics. This paper introduces an AR-based application for learning about the Doppler effect and investigates its educational effectiveness on students' learning achievement, interest,…

Children who are deaf or hard-of-hearing (D/HH) learning in inclusive educational settings must be aware of how well they hear and understand spoken language to advocate for themselves. This study explored elementary-age children's self-reported listening abilities using thematic analysis of brief interviews. Participants were 16 D/HH and 16…

This within-subjects experimental study investigated the relative effects of word reading and word meaning instruction (WR+WM) compared to word-reading instruction alone (WR) on the accuracy, fluency, and word meaning knowledge of 4th-5th graders with dyslexia. We matched word lists on syllables, phonemes, frequency, number of definitions, and…

Given the important role played by students' spatial reasoning skills, in this paper we analyse how students use these skills to solve problems involving 2D representations of 3D geometrical shapes. Using data from in total 1357 grades 4 to 9 students, we examine how they visualise shapes in the given diagrams and make use of properties of shapes…

There is currently significant interest in 3D fabrication in middle school classrooms. At its best 3D printing can be utilized in authentic design projects that integrate math, science, and technology, which facilitate deep learning by students. In essence, students are able to tinker in a virtual world using 3D design software and then tinker in…

The importance of design and technology (D&T) education has been advocated by numerous researchers over the last three decades. For instance, Nigel Cross suggests that in design education, there are ill-defined problems and "designerly ways of knowing" (2006). Today D&T in school education is employed globally and the common…

In this research we explore the pedagogical affordances associated with the use of a 3D printer in a middle school classroom (11-12 years old). We introduced the 3D printer in a classroom where no one, including the teacher, had prior knowledge of 3D printing. Lessons using the 3D printer were designed to correspond with the mathematics curriculum…

This study examined the effect of using Monoscopic Three-Dimensional (M3D) and Stereoscopic Three-Dimensional (S3D) animation on students' achievement and perceptions. A total of 66 ninth-grade students participated in this Explanatory Sequential Mixed Design study. At the beginning of the study, an academic achievement test was applied, and then…

This cluster randomized controlled trial evaluated the efficacy of the CHAMPS classroom management program on the social behavioral and academic outcomes of a large diverse sample of middle school students within an urban context. Participants included 102 teachers and 1,450 students in sixth to eighth grade. Two-level hierarchical linear models…
