Hydrogels are soft water-rich materials with physical properties that can be easily tuned by modifying their network structure. For instance, increasing or decreasing the cross-linking density has a profound effect on their water absorption capabilities and mechanical strength. These physical changes are showcased in a new experiment for organic…

A procedure to purify anthocyanin, a natural pigment, following a green approach by using macroporous resin and its encapsulation for the maintenance of its stability is described. This laboratory experiment, which describes the benefits of using resin for the purification, is a learning tool for students working in the field on nutraceuticals.…

An experimental design by combining hydrogel and ethylenediaminetetraacetic acid disodium salt (EDTA) for visually displaying chemical complexation reactions is developed. The Na[superscript +] ions on the [alpha]-l-guluronic acid (G) unit of the sodium alginate molecule undergo an ion exchange with a divalent cation, so that the G units are…

A pilot study, funded by the Gatsby Charitable Foundation, supported 10 secondary schools across England to plan and deliver open-ended investigative practical work within science curriculum time. This enabled all students to experience the benefits of investigative work, rather than just those attending extracurricular STEM enrichment activities.…

Solving organic chemistry reactions requires reasoning with multiple concepts and data (i.e., multivariate reasoning). However, studies have reported that organic chemistry students typically demonstrate univariate reasoning. Case comparisons, where students compare two or more tasks, have been reported to support students' multivariate reasoning.…

Research reveals that teachers regularly refer to intuitive construals (IC) in formal science education. Only a few studies, however, have investigated why teachers refer to them. Alarmingly, these studies suggest didactic consideration is not the main reason for this. Instead, teachers introduce IC unintentionally or due to a lack of expertise. A…

The rise of social media platforms and subsequent lack of traditional gatekeeping mechanisms have enabled the proliferation of scientific disinformation. Users attempting to properly evaluate scientific information and disinformation are immensely obstructed by media communication mechanisms such as filter bubbles and echo chambers. Given the…

"The Framework for K-12 Science Education" and the Next Generation Science Standards require teachers to integrate engineering design into K-12 science teaching. However, many teachers have no formal preparation in engineering design and how to integrate it into science instruction. Furthermore, few models exist for preparing teachers in…

Teaching and learning relies on age-appropriate, credible formal (e.g., textbooks, textbook supplements) and informal (e.g., trade-books) curricular texts. Previous research traced American publishers' self-censorship about human evolution within twentieth-century textbooks. This study, informed by the latest scientific understandings, engaged in…

Much research attention has been focused on learning through game playing. However, very little has been focused on student learning through game making, especially in science. Moreover, none of the studies on learning through making games has presented an account of how students engage in the process of game design in real time. The present study…

This paper explores the use of comics as an integrated tool for introducing socioscientific issues (SSI) in elementary school classrooms. To illustrate this, we provide implementation examples from two teachers who facilitated introducing SSI to students using comics. These case studies depict how teachers integrated comics into their classroom…

Contribution: This article applies science capital research to computing education in order to understand why students engage with a programme involving computing, and what they aspire to get out of their education. Background: Capital is a concept which has been used in educational research to study inequality, aspiration and achievement.…

This dissertation examined the relationship between elementary school science teachers' epistemic orientation and classroom learning environment type--generative or replicative--they established for science knowledge development. Drawing on the theory of epistemological development and understanding, the influence of teacher epistemic beliefs on…

This study examined the impact of spatial ability on science achievement by distinguishing between domain-general and domain-specific spatial abilities, focusing on their relationship with the conceptual understanding of the apparent path of the sun. Additionally, the mediating effects of domain-specific spatial knowledge on the relationships…

The essence of university courses lies in their scientific rigor, while the enjoyment of learning serves as a motivation. In this regard, we have developed a comprehensive experiment project by incorporating dithienylethene-based photochromic units into sensitizers for renewable energy, specifically dye-sensitized solar cells, through organic…
