This study aimed to evaluate the effectiveness of the Prime Factors Chart (PFC) as an alternative teaching material, which was developed for teaching the concepts within the "factors and multiples" unit in the middle school mathematics curriculum. Twelve middle school mathematics teachers used the PFC to teach concepts, such as prime…

Have you ever noticed trash collecting in streams or waterways? How does trash influence our environment, and what can be done to enact change? These are questions middle school students explored as the authors launched the Great Pacific Garbage Patch (GPGP) task. The Great Pacific Garbage Patch activity involves an urgent environmental issue that…

R and Python are commonly used software languages for data analytics. Using these languages as the course software for the introductory course gives students practical skills for applying statistical concepts to data analysis. However, the reliance upon the command line is perceived by the typical nontechnical introductory student as sufficiently…

We propose a novel model for learning environments to target the characteristics of digital natives and to improve informal learning practices, i.e. the exploration, discovery and self-monitoring of learning content and the reflection on learning activities. The Mobile Playful Learning Environment (MPLE) model is defined as consisting of seven…

Young adolescents build notions of figures through experiences. When young adolescents begin middle school mathematics, they already have prior assumptions and conceptualizations about shapes (Herbst, Fujita, Halverscheid, & Weiss, 2017). Over years of experiences, interactions, and exposures with a particular concept, these students develop…

Research was reviewed that focussed on the reading comprehension abilities of students with Autism Spectrum Disorders (ASD). Although single-case experimental design (SCD) is an accepted and widely used way in which to evaluate an evidence-based practice, very few studies met the What Works Clearinghouse (WWC) standards for evidence-based SCD…

This dissertation sought to understand the evolution of four elementary teachers' (grades 1-3) teaching of science with representations over the course of one year of participation in a multi-structured professional development (PD) project referred to as RepTaL. The notion of learning to teach science using a range of representations is a…

This is a visual representation and commentary on a taxonomy for the emerging scholarship of educational development.

Geometry is an essential component of mathematics which promotes the development of critical thinking and problem-solving skills. Geometry shapes are an integral part of our lives. This study focused on the teachers' practices, specifically on how teachers ought to be equipped with a good understanding of the effectiveness of the use of diagrams…

Textbooks are one of the primary sources for students to obtain knowledge, so they should present accurate knowledge through textual and visual representations. The goal of the current study is to examine the representations in middle school science textbooks based on the diagram coding scheme to find out a general picture of how representations…

Scientific knowledge is not communicated through the verbal mode only but through the integrated use of tabular, graphical and verbal forms, a fact that has positioned visual understanding as a major element of literacy demands to acquire advanced knowledge. In spite of this, empirical studies on how scientists develop meaning out of visual data…

This study aims to find out the effects on pre-service teachers of a constructivist teaching approach aided by use of a Porphyrios-tree. Use of a Porphyrios-tree is thought to be the basis of and most principled conceptual teaching tool to aid meaningful comprehension about concepts of interspecies relationships. The study has a quasi-experimental…

PicDiversity, Inc. is working to solve the problems about media in the classroom. Where do teachers go to find diverse media for their students? Students deserve to feel recognized and valued, seeing themselves reflected in the lessons provided. This article presents PicDiversity and how it can transform media in the classroom. PicDiversity's goal…

The aim of this study is to contribute to a better understanding of the nuances of multimodal communication through which educational designers construct shared meanings and ideas. Educational design is a broad and multi-faceted area. Meaning-making in face-to-face educational design meetings is a complex process but is yet to gain attention as a…

Creative thinking is the cognitive activities that process the received information to produce new representations. Therefore, it is necessary to develop creative thinking and represent a problem. This study aims to investigate the students' creative thinking processes based on representation in solving mathematical problems reviewed from…
