In this article Sophie Harley-McKeown identifies and addresses her Year 12 students' blind spot over agentive explanation. Noticing that the examination board to which she teaches uses 'motivations' rather than 'aims' prompted her to consider whether her students really knew what that meant. Finding that her students' causal explanations tended to…

The objective of this study was to analyze visual representations of redox reactions and related content in four Brazilian secondary school chemistry textbooks. The study aimed to identify which representations were used and to evaluate how these representations were linked to one another and to the main text. Data were analyzed regarding…

Through a close reading of five nineteenth-century instructional books in the Osborne Collection of Early Children's Books, this essay examines the relationship between new print technologies, memory, teaching, and learning. The article beings with a discussion of Comenius's seventeenth-century "Orbis Pictus," considered the first…

According to Sinclair, Pimm, and Skelin (2012), the four big ideas of high school geometry are (1) diagrams; (2) variance and invariance; (3) definitions; and (4) proofs as the culmination of the proving process. On the first day of geometry class, Wayne Nirode began a multiday activity in which students were actively involved in working with…

Kelley's Discrimination Index (DI) is a simple and robust, classical non-parametric short-cut to estimate the item discrimination power (IDP) in the practical educational settings. Unlike item-total correlation, DI can reach the ultimate values of +1 and -1, and it is stable against the outliers. Because of the computational easiness, DI is…

Recently, researchers have paid extensive attention to colorimetric/fluorimetric probe development and its applications in biological and industrial samples. The actual development of such probe molecules, however, often requires an iterative process to achieve certain goals such as selectivity and sensitivity toward a target analyte. In spite of…

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense…

Resource allocation has become an activity with high criticality and impact on product delivery, going to transformation into a process involving multiple stakeholders. The purpose of this paper is to present the results of a PhD research with defined resource allocation diagram, process and subprocesses, based on previous work results analysis…

Informal learning environments can be a fun and effective means of introducing visitors to a variety of topics in evolution. Our study examined 120 sixth-grade students' conceptualisation of evolutionary ideas following three evolution-themed "Science Days" at 'Nature Campus'--an informal learning environment in Central Israel comprised…

In this research, a new test for understanding simple fractions has been developed for students at the beginning of lower secondary education. In many countries, mathematics education in Grade 5 builds on elementary students' developing concepts of fractions. Understanding fractions causes many difficulties for students, and research on mental…

Introduction: There is a history of overlap between art and science education, particularly in anatomy and other related medical specialties. Technological advances have increased exposure to visual images and creation and sharing of image-based content is commonplace. Statement of the Problem: The use of visual content and activities in education…

Visual scaffolding, a type of scaffolding provided in a visual format, is considered to have potential in web-based learning environments as it naturally includes tacit information, highlights the critical features of tasks and promotes learning through the spatial organization of tasks. However, systematic approaches to visual scaffolding design…

Problem solving has been the focus of the Common Core State Standards for Mathematical Practice. Helping students acquire critical-thinking and problem-solving skills has become the primary goal of mathematics education across all grade levels. However, research has found that many students struggle with word problems because of poor text…

During the 1960s, Edgar Dale published the concept that learners are likely to retain more information if they see and hear information rather than just listen. Therefore, many educational applications have been created for students to learn theoretical concepts through visuals and in an interactive manner. Microsoft (MS) Excel has been used in…

In this article we identify ways to scaffold content-specific instruction to support your multilingual learners' academic language development. With the definition that academic language compromises of vocabulary, linguistic functions, and syntax, we share ways to integrate three instructional practices across your instruction. These practices…
