Reforms within science education strive to shift early science instruction (K-2) so students have ample sense-making opportunities to construct scientific explanations. Classroom discussions play a key role in supporting these endeavors. This requires that classroom discussions are shaped in ways that foster scientific instruction and learning. In…

The science education community is deeply invested in growing the next generation of scientists. One way to do this is through evidence-based interventions that support the motivation and performance of students in introductory classes. The literature is replete with interdisciplinary research presenting such interventions. Unfortunately, the…

Information and Communication Technology (ICT) is commonly employed in biology classes to facilitate students' comprehensive comprehension of biological processes and enable them to see living phenomena. The purpose of the study was to explore the use of ICT in enhancing the teaching and learning process of biology in the secondary schools of…

Calculating analytical uncertainties as a part of method validation is a relevant aspect of field and laboratory practices in instrumental analytical chemistry subjects, which usually require complex algorithms. This work describes the development and didactic use of an automatic and straightforward informatics tool, implemented in an Excel macro,…

To address the challenge of improving the understanding of chemistry concepts, particularly pH, this study explored the impact of integrating educational robotics on students' motivation and learning outcomes. A total of 160 3rd-year middle school students from a public school in Meknes, Morocco, participated in the study, which was divided into…

Multiple external representations (MERs) are useful for teaching complex content in science education. An open question is whether there is an especially effective way to sequence MERs. On the one hand, the so-called concreteness fading approach suggests starting instruction with more concrete representations and proceeding stepwise to more…

"Those who can't do, teach." This adage is common, perhaps because the general public does not fully understand what teachers do. Here, we describe our findings from a collaborative project, GIFT (Graduate Identity Formation through Teaching), in which STEM graduate students (GSs) taught science content to teacher candidates (TCs) and…

Students need a strong understanding of how to represent chemical compounds in order to succeed in organic chemistry. This project set out to gain a better understanding of students' difficulties with symbolic representations, by identifying the specific errors associated with drawing wedge-dash structures. The focus was on how students…

As a model study for improving undergraduate organic chemistry laboratories with contemporary research concepts and practices, we evaluated a project module aiming at the synthesis of two porphyrin compounds. The module was implemented in a format that differed in several ways from that of a traditional course. It was designed for small student…

Human-driven carbon emissions have resulted in increased levels of dissolved carbon dioxide in the Earth's oceans. This dissolved carbon dioxide reacts with water to form carbonic acid, which impacts ocean acidity as well as the solubility of carbonate-containing compounds, with far-reaching impacts on marine ecosystems and the human communities…

Causal mechanistic reasoning is a thinking strategy that can help students explain complex phenomena using core ideas commonly emphasized in separate undergraduate courses, as it requires students to identify underlying entities, unpack their relevant properties and interactions, and link them to construct mechanistic explanations. As a…

The study examines the role of independent work in enhancing the genetic knowledge of third-year biology students within a multilingual education setting. Conducted at Abai Kazakh National Pedagogical University, the research involved 164 biology teacher candidates. A quasi-experimental design with pre-test and post-test measures was employed to…

As the COVID-19 pandemic transformed higher education, St. John's University (New York), among other academic institutions, worked to incorporate methodologies that would allow for social distancing and the attainment of hands-on experience that is expected of a science laboratory course. To account for the constraints that the pandemic posed, St.…

Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

Background: The views of the nature of science (VNOS) is one of the important goals of science education. According to information processing constructivism, learners' psychological factors that may influence VNOS include scientific argumentation (SA), metacognition (MC) and epistemic beliefs (EB). Purpose: This mixed-methods study aims to analyse…
