The lack of accurate and comprehensive sexual health education in the USA persists as a pressing public health issue. The Sex Wrap (TSW) is a multimedia sexual health podcast and social media presence that educates followers on sexual health and ancillary themes such as sexuality, relationships and communication. TSW's Instagram account repackages…

This study was conducted to optimize the designs of learning guides embedded in a computer-based simulation environment. The research was based on the Cognitive Theory of Multimedia Learning and Cognitive Load Theory. We investigated computer simulations under four conditions that combined representation and imagination learning strategies. This…

A previous study mentioned that students' action responses towards water pollution are incongruent with the training they received in schools. Conducting a course of two weeks with elementary students (N = 22) aged 9-10 in Hong Kong, the study aims to connect primary students' perceptions of the causes, consequences and responsive actions on water…

Computer programming is regarded as an important skill for the future. However, many K-12 students face challenges and difficulties in learning traditional text-based programming. Block-based visual programming (BVP) can reduce the difficulty of learning programming and is seen as a potential programming education tool. Nevertheless, the effects…

Data visualization is a complex matter and so is teaching it in the context of engineering and data science. Even more challenging is teaching in a midst of once in a century pandemic. In this paper, we show the results of a workshop conducted with second-year students on a university degree in data science, which took place in the context of…

Several studies have shown that "learner-generated external visual representations" (LGVRs) play a vital role for learning scientific concepts and processes. However, we know little about teachers' reasoning as to why and how to implement LGVR activities in their teaching. Thus, the purpose of our study is to determine why teachers let…

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…
