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…

Climate change is of great concern to all age groups but in particular to children. "Simple" climate models have been in place for a long time and can be used effectively with post-16 students. For younger children, modifications are required, and we describe in this paper the development and use of two such models. The first (the Granny…

Correlational studies link spatial-test scores and science, technology, engineering, and mathematics achievement. Here we asked whether children's understanding of astronomical phenomena would benefit from a prior intervention targeting a core component of children's projective spatial concepts--understanding that viewers' visual experiences are…

The Next Generation Science Standards regard biological structures at both the micro and macro levels as a core idea of life sciences and expect students to understand animals have external structures that perform diverse functions. Using the common creature of bees as a case, this study aimed to ascertain teenage students' ideas of bees through…

Mastering creative thinking skills (CTS) is crucial for enhancing students' science conceptual understanding. However, conventional teaching prioritizes linear thinking over the three sub-CTS essential to science learning: associative, visual, and divergent thinking. Weaknesses in these three sub-CTS cause students to have misconceptions,…

Due to the difficulty of chemical compounds to visualize, augmented reality (AR) integrated with mobile learning has been developed as an alternative media for studying chemistry. This study aims to analyze the use of AR-integrated mobile learning in chemistry education from a bibliometric perspective in the last decade. A total of 225 articles…

Students' individual characteristics influence the effectiveness of instruction and learning and, therefore, the depth of learning. This study brings forth the voices of middle school students regarding their science learning preferences through four modalities: visual, auditory, sensorimotor, and agency support. We examined the relationship…

Educational games have attracted attention as valuable didactic instruments since they combine a proven efficiency in learning improvement with a fun and enjoyable atmosphere. Despite the increasing number of educational game contributions treating a wide variety of topics, to the best of our knowledge, none revise units or physical quantities.…

This qualitative, ethnographic study focuses on how combining aspects of visual learning with a social media application (app)--Instagram--can be a useful learning tool for digital natives (DNs). Current students are classified as digital natives because they are inundated with technology, which has become an essential tool in their everyday…

The image is the raw material of the twenty-first century. Images infiltrate all social and cultural spaces. Its digital-mediated realities drive communication, industry and knowledge. Images saturate life and adolescent learners are familiar with the participatory nature of image production and its social, educational and personal communicative…
