The active participation of citizens in scientific research, through citizen science, has been proven successful. However, knowledge on the potential of citizen science within formal chemistry learning, at the conceptual and procedural levels, remains insufficiently explored. We developed a citizen science project -- PVC: Perceiving the Value of…

Teacher knowledge is vital to provide meaningful learning opportunities. In this case study, a secondary education teacher's knowledge about how to teach the concept of ecosystems from a river is explored. A category system drawn from the literature about science teacher knowledge was used for the analysis. Science teaching requires teachers to…

Archimedes' principle is one of the foundation subjects in physics. Normally the principle is exemplified by reference to floating boats. However, Archimedes' principle also applies to objects embedded in waterlogged ground, which can lead to the surprising result of an object weighing several tons being lifted. A practical example is presented of…

General Chemistry serves virtually all STEM students. It has been accused of covering content in a "mile wide and inch deep" fashion. This has made it very difficult to assess, where chemistry educators have relied on assessments of specific topics. Assessing across all these different topics requires introducing many different chemical…

At present, there are alarming reports raising serious concerns about water availability in many countries including Morocco. In this context of water scarcity and increasing water demand, education may play a crucial role in transforming values and habits that promote a sustainable management of the resource. Therefore water education topics…

The body is often ignored, in elementary science education, as a site of knowledge, meaning, and feeling. This study explored how embodied performances, defined as drama- and movement-based representations of science ideas, spontaneous or rehearsed, shaped construction and communication of science knowledge and identities among Latinx fifth…

Thirty-six students enrolled in Organic Chemistry II participated in individual, semistructured, think-aloud interviews about the factors that contribute to the stability and reactivity of organic species in the context of unimolecular and bimolecular nucleophilic substitution and elimination reactions. The students were provided with the…

Many educators have utilized the phenomenon of the so-called "hydrostatic paradox" to actively engage students in classroom instructional activities related to hydrostatic equilibrium. Various approaches requiring different levels of mathematical knowledge have been proposed in the literature to provide students clear explanations of…

Interdisciplinary studies foster integration of ideas across disciplines. The knowledge building pedagogy, with its 12 principles and associated technology, Knowledge Forum®, provides multifaceted support for linking ideas across disciplines and communities. This exploratory study aims to assess the extent to which elementary-school students…

The study of water as a K-12 science idea often divorces its properties from its deeply politicized history as a resource that has been limited, compromised, and intentionally withheld from nondominant communities. Although a robust body of scholarship has aptly critiqued decontextualized and depoliticized pedagogies and called for critical…

Summer camps have proven to be effective tools to engage students in the geosciences. Findings from this study highlight perceptions and experiences of middle school students from predominantly African American school districts in Mississippi who attended a 3-d residence camp focused on increasing interest in the geosciences through an earth…

A field-based environmental geochemistry course was developed at Western Michigan University for undergraduate geosciences and environmental studies students to (1) improve student understanding of complex environmental systems, specifically targeting lake systems; (2) facilitate student development of professional-level, field- and…

The use of informal science education in rural areas, especially at rural middle schools has not been well documented. Although rural areas have accessible outdoor learning environments compared to urban areas, teachers are less likely to incorporate informal science activities. The purpose of this study was to evaluate two seventh grade life…

In pursuance of one of the goals of the new South African curriculum to integrate science with Indigenous Knowledge Systems (IKS), this study, which forms part of a larger study, is concerned with determining teachers' and learners' conceptions of a number of familiar natural phenomena. Several recent studies have indicated that: (1) learners do…

In introductory chemistry courses students are presented with the model that matter is composed of particles, and that weak forces of attraction exist between them. This model is used to interpret phenomena such as solubility and melting points, and aids in understanding the changes in states of matter as opposed to chemical reactions. We…
