Sustainability has a molecular basis that suggests a central role for chemistry in addressing today's challenges to Earth and societal systems, and this role requires educators to see chemical reactions and processes as integral parts of dynamic and interconnected systems. Despite this prospect, few accessible resources are available for students…

This exploratory study investigated the relationships between time utilisation and the use of visual resources, supported by audiovisual records of the practices of pre-service chemistry teachers applying Teaching-Learning Sequences. The content analysis was based on analytical categories found in the scientific literature. The results showed a…

Even though the "Next Generation Science Standards" (NGSS) were released over a decade ago, science is still infrequently taught in early childhood and elementary classrooms. A lack of teacher confidence due to inadequate content knowledge may be a contributing factor, making access to high-quality elementary science methods courses even…

The educational benefit of the traditional didactic lecture to learners in Higher Education is hotly debated. Given increasing student numbers, existing technical set ups and many logistical concerns, lectures remain the norm in many Higher Education Institutions (HEIs). In this personal view piece, we discuss the benefits, opportunities, and…

Interactive molecular dynamics in virtual reality (IMD-VR) simulations provide a digital molecular playground for students as an alternative or complement to traditional molecular modeling kits or 2D illustrations. Previous IMD-VR studies have used molecular mechanics to enable simulations of macromolecules such as proteins and nanostructures for…

The use of group drawing to promote student-generated representation is a common instructional strategy as it combines the benefits of using visual representation and collaborative talk. Although the affordances of group drawing have increasingly been emphasized in science education, few studies have investigated how drawing as a visual mode…

This paper was part of a larger study to examine one primary and one secondary teacher's classroom. The study analysed the classroom discourse to describe the types of interaction and illustrate how the teachers used talk moves to mediate talk for learning science around visual representations (VRs). The study employed ethnographic approaches to…

Laboratory exercises are a crucial component for many science education courses. Hands-on activities provide valuable contextualized learning experiences and allow for increased engagement between students and technical knowledge. The present study examined the efficacy of a virtual-type laboratory activity compared to a traditional hands-on…

Central to evolution is the concept of a common ancestry from which all life has emerged over immense time scales, but learning and teaching temporal aspects of evolution remain challenging. This study investigated students' interpretation of evolutionary time when engaging with a multi-touch tabletop application called DeepTree, a dynamic…

Simulations that combine real world components with interactive digital media provide a rich setting for students with the potential to assist knowledge building and understanding of complex physical processes. This paper addresses the problem of modeling the effects of multiple students' simultaneous interactions on the complex and exploratory…

The findings of the research literature about the necessity and contribution of Interactive Whiteboards (IWB) are not unequivocal and are sometimes contradictory. The study aimed to examine the interactive attributes in lessons with an IWB and the students' attitudes. Methodical structured observations of 26 science lessons were conducted in…

This study examines the attitudes of students on the use of PowerPoint and chalk/white boards in college science lecture classes. Students were asked to complete a survey regarding their experiences with PowerPoint and chalk/white boards in their science classes. Both multiple-choice and short answer questions were used. The multiple-choice…

This paper reports on a study of students' conceptual sensemaking with science diagrams within a computer-based learning environment aimed at supporting collaborative learning. Through the microanalysis of students' interactions in a project about energy and heat transfer, we demonstrate "how" representations become productive social and cognitive…

Teachers make pedagogical decisions in their planning and use of interactive whiteboard (IWB) technologies. Intentional teaching incorporating IWB and interactive planning software requires deliberate selection and sequencing of digital resources. The research reported in this paper explored and documented teacher and student use of IWB technology…

An introductory organic classroom demonstration is discussed where analogies are made between common societal hand contact and covalent bond formation. A handshake signifies creation of a [sigma] bond ("head-on" orbital overlap), whereas the action of praying illustrates "sideways" overlap and generation of a [pi] bond. The nature of orbital and…
