Creativity is not only for gifted students, but also for regular ones. This case study was aimed to analyze the appropriateness of tasks and the elaboration of multiple solutions to occasion fourth-graders' mathematical creative thinking through a documentary multiple-solution counting task in a figurative setting. The data came from the written…

The research on computer mediated interventions and technologies (e.g., digital tabletop tool) that have seminal relevance to the intervention strategies designed for the children diagnosed with Autism Spectrum Disorder (ASD) mostly remain confined within the developed nation. The objective of this study is threefold: firstly, to reveal the design…

High school administrators, teachers, coaches, and guidance counselors, collectively termed as educators, are responsible for educating teenage students while preparing them for adult life. High school students culminate their education not just with a diploma, but also a decision about what to pursue as an adult. Although there is a common desire…

Many stakeholders emphasize the importance of diverse populations' participation in the sciences, though the motivations for this vary. Some reference an economic standpoint by emphasizing the importance of either recruiting more science workers to compete in a global economy, or of individual financial success for people from historically…

This study aims to investigate the process of designing infographics through participants' knowledge construction in the assessment and evaluation process of IB Educator Certificate (IBEC) educational technologies education. The study, in which the case study method was used, was conducted with 12 participants who attended the educational…

Paraprofessionals are a crucial component of special education services and can be vital to promoting inclusive learning opportunities. Although intentions behind utilizing paraprofessional support may be good, students with disabilities may become over-reliant on paraprofessionals, thus limiting student independence in the classroom. This paper…

The main purpose of this study was to describe the development and use of a flowchart for preservice chemistry teachers' problem solving on the First Law of Thermodynamics. Twenty-seven undergraduate preservice chemistry teachers attending a Physical Chemistry course participated in this study. The responses of the participants to the set of test…

This article explores the role that gestures play in the development of mathematical understanding. Using Pirie Kieren's (1994) notion of image making and Lunney Borden's (2011) idea of verbing mathematics, we share two examples of how students respond to teacher requests to demonstrate what they know about arrays.

Text-picture integration is one of the most important cognitive processes when reading illustrated text. There is empirical evidence that text-picture integration takes place when learning with pictures combined with single sentences. The present experiment investigated whether text-picture integration also takes place when the single sentences…

Using the layout described here (which could be photocopied or handwritten), students can see how the periodic table was first envisaged after finding similarities in the properties of common elements. Then, with more discoveries some gaps were filled and, when additional elements did not fit, new groups had to be included.

In this paper we are interested in the relationship between disciplinary knowledge and its representation. We carry out a social semiotic analysis of a central tool used in astronomy--the Hertzsprung-Russell (H-R) diagram--in order to highlight its disciplinary and pedagogical affordances. The H-R diagram that we know today combines many layers of…

This paper mainly proposes a simple method to record scattered light rays via photography, presenting a clearer and brighter representation of the optical path. This technique is applied to the double-slit interference experiment and single-slit diffraction experiment typically conducted in general physics courses, and shows the intuitive results…

Little attention has been paid to the processes that are involved in making sense of the role dissonance between sources of data has played in the development of theoretical insight. This methodologically oriented investigation considers an unusual set of case exemplars that used mixed methods and dialogic forms of mixing in ways that produced…

The paper considers the particular value of focusing on the look as a medium when studying visual cultures. This focus is helpful for coming to terms with distinct understandings of the visual. To address the look as a medium, four analytical dimensions are introduced for distinguishing among separate but closely interrelated visual phenomena: the…

Ray diagrams are widely used in introductory physics textbooks to illustrate the behavior of ideal systems of lenses or mirrors in geometrical optics. Their virtue lies in their explicit display of multiple ray paths connecting object and image points, which leads naturally to an understanding of how a planar object is transformed into a planar…
