Satisfaction is an important usability attribute in developing a courseware which involves end users. Measuring satisfaction among hearing-impaired students is different than measuring it among common students because they learn using sign language and have different learning styles. An educational courseware for hearing-impaired students is…

Using real-world situations to engage students in learning specific content is advocated by educational research as an effective strategy. However, motivating students to establish personal and emotional connections with the curricular content is challenging. We presented a didactic strategy named "the presidential election of the human…

Worldwide, teachers are expected to engage their students in authentic practices, like scientific modeling. Research suggests that teachers experience challenges when integrating modeling in their classroom instruction, with one explanation that teachers themselves lack the necessary modeling competence. Currently, theoretical conceptualizations…

High school science classrooms across the United States are answering calls to make computation a part of science learning. The problem is that there is little known about the barriers to learning that computation might bring to a science classroom or about how to help students overcome these challenges. This case study explores these challenges…

The natural sciences, by their very nature, are based on the exploration of the physical world, and digital mobile devices are considered appropriate to support this exploration (Suárez et al., 2018) since they offer the tools that make this investigation more accessible but also ubiquitous (Crompton et al., 2017). Inquiry-based learning is a…

Assessment of deaf children has found that their early understanding in science is behind that of their hearing peers. Research shows that parental attitudes and behaviours can affect educational outcomes but few studies have considered the effects of attitudes towards science on parent/child interactions in the home and thus, the effects on…

In earlier studies, it has been argued that drama has the potential to stimulate learning in science. However, it is not widely used, one reason being that science teachers are not familiar with this instructional strategy. In this study, it was investigated how pre-service teachers in science developed dramas related to content in a biology…

Public trust in science and expertise remains a contentious issue. When public trust is analysed, it often simplifies a complex process of information retrieval and interpretation. Questionnaire surveys help us make sense of differences among actors and countries, but they fail to provide a comprehensive analysis of the reasons that lead citizens…

The use of technology in assessment continues to evolve the field of educational measurement. This article reports on development and use of new accessible, technology-enhanced assessments designed to measure the three-dimensional science abilities of middle school students. The assessments were piloted with over 70 teachers and 8,000 students…

Ever since Newton's groundbreaking work on the composed nature of light, additive colour mixing (and its laws) are subject to the interest of physicists as well as other sciences. In this paper, we present a setup for simple lab or home experiments on additive colour mixing and the laws of colour mixing. Students use the screen of a laptop or…

In this work, an alternative Experimental Didactic Kit for teaching resistors, capacitors and "RC" timing circuits was developed, using the Arduino platform technology, which is composed of a microcontroller and peripherals, due to the easy access to available teaching materials, enabling the reproduction of the prototype in the future…

Sixth-grade science students at Gauger-Cobbs Middle School in Newark, DE, had misconceptions about how heat energy moves in the hydrosphere through conduction, convection, and radiation. As a result, students struggled to develop and connect ideas that correctly and completely explained heat transfer in the hydrosphere at the end of the lesson…

This is a study of teachers transition after a professional development (PD). The purpose was to document and characterize the teachers' experiences as they transitioned toward use of the Next Generation Science Standards (NGSS) and more learner-centered teacher practices. The teachers participated in a PD workshop that provided information on the…

Determining how to increase practicing elementary teacher science instruction self-efficacy through ongoing professional development has been a problem in one urban Texas school district. Existing literature indicated science instruction self-efficacy could be built using professional development. However, there is a gap in the literature…

Using Constructivist Grounded Theory (CGT) and reflexive Thematic Analysis (TA) methods, the purpose of this case study was to construct theory about equity for students studying chemistry at public universities in Colorado. Interviews with students (N=12), chemistry instructors (N=9), and equity practitioners (N=9) as well as observations of…
