To become scientifically literate, students need to interpret science concepts using numbers, text, and visuals (Lemke 2004). Scientists use multiple modes to communicate their ideas to each other and the public, including images, text, mathematical notations, symbols, diagrams, charts, and graphs. Several of the science and engineering practices…

As engineering learning experiences increasingly begin in elementary school, elementary teacher preparation programs are an important site for the study of teacher development in engineering education. In this article, we argue that the stances that novice teachers adopt toward engineering learning and knowledge are consequential for the…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

Moving among levels of abstraction is an important skill in mathematics and computer science, and students show similar difficulties when applying abstraction in each discipline. While computer science educators have examined ways to explicitly teach students how to consciously navigate levels of abstraction, these ideas have not been explored in…

Cross-curricula opportunities afforded by STEM education (Science, Technology, Engineering and Mathematics education), supports an environment where students can develop twenty-first century competencies. One approach to addressing cross-curricula opportunities in STEM education is the introduction of computer science (computer…

Multiple-source inquiry that involves collaboration and deliberation is a complex construct; accordingly, valid measurement of these related competencies should require students to demonstrate their collaborative inquiry and social deliberation skills as part of an integrated performance. In this article, we report findings from the first phase of…

A large body of research has examined students' conceptions of evolution and their relationships to acceptance of evolution. Proficiency in statistical and probabilistic reasoning has long been considered to be an essential feature of evolutionary reasoning, yet almost no empirical work has explored these putative connections. The RaPro…

We present a multiple-choice test, the Montana State University Formal Reasoning Test (FORT), to assess college students' scientific reasoning ability. The test defines scientific reasoning to be equivalent to formal operational reasoning. It contains 20 questions divided evenly among five types of problems: control of variables, hypothesis…

This study aimed to explore the relationships between students' perceived learning practices and associated self-efficacies regarding mobile-assisted seamless science learning. The learning practices for mobile-assisted seamless science learning questionnaire was developed with three scales that denote learning supported by mobile technology.…

For the last seven years, an interdisciplinary course known as "Greener Solutions", offered by the University of California, Berkeley Center for Green Chemistry, has brought together graduate students in chemistry, environmental health, and engineering to understand each other's disciplines, and to work together to develop safer…

New technologies are changing the ways that children navigate, find places, make and use maps, and explore the world. This is the geospatial revolution. Children live in a world of rapid technological innovation bringing new opportunities for cognitive development in school geography. Geography learning is an important component of primary school…

Recognising critical reasoning and problem-solving as one of the key skills for twenty-first century citizenship, various types of problem contexts have been practiced in science classrooms to enhance students' understandings and use of evidence-based thinking and justification. Good problems need to allow students to adapt and evaluate the…

Although the relationship between the classroom learning environment and academic achievement has been explored in subject-free and disciplinary subject contexts, research into this relationship is still lacking in the context of interdisciplinary subjects. This study investigated the relationship between the classroom learning environment and…

The Computer Science Teachers Association has asserted that computational thinking equips students with essential critical thinking which allows them to conceptualize, analyze, and solve more complex problems. These skills are applicable to all content area as students learn to use strategies, ideas, and technological practices more effectively as…

"Building Computational Thinkers," a three-year research study, explored how educators and designers can most effectively support the development of computational thinking capacity, and how these learning experiences could be customized to meet the needs of different learners. This research study focused on three specific exhibit design…
