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,…

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…

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…

Chemical thinking has been widely recognized as a core competence for supporting students' problem solving in chemistry education. Disciplinary essential questions and perspectives are two critical aspects of chemical thinking. This study connects essential questions with such perspectives to develop a new framework for restructuring chemical…

This paper presents two low-cost hands-on activities designed to enhance student understanding and address the pedagogical challenges faced by microbiology professors in teaching concepts related to cell structure and gene regulation. In the first activity, we used Shrinky Dinks and Jeopardy-style game questions to explore the differences between…

This study explored the views of 63 Taiwanese pre-service teachers who had participated in a workshop about the value of integrating drama-based approaches in their practical science learning. It was primarily designed to investigate the pedagogical approach of Heathcote and other founders of process drama. In addition, it examined specific claims…

The underrepresentation of Black Americans in physics has been persistent for so long that it seems to have constrained physics educators' collective imagination when it comes to conceptualizing and pursuing equity in physics teaching and learning. Drawing on a teacher research study that foregrounds justice-centered physics teaching, this article…

Instructional explanations are sometimes viewed as part of a nonconstructivist, solely teacher-centered learning environment, leading to the perception that they are ineffective or inappropriate for teaching science. Consequently, teacher education programmes seldom focus on preparing teachers to explain scientific concepts effectively.…

Communication skills require students to be able to manage, understand, develop, and create orally and in writing. Teaching methods that generally use conventional models of learning activities that are not formed in groups cause students' science communication skills to be lacking, so learning activities are more teacher-centered. This learning…

The worldwide impact of the COVID-19 pandemic has been enormous. It has affected the justification of the contributions from academia, and resulted in rapid spreading of misinformation and conspiracy theories. The use of the social media has during the pandemic intermixed the space between the private and the public domain, and has interfered with…

Issues in learning, particularly the utilization of learning resources, have not been maximized to facilitate teachers in guiding students to learn certain concepts related to the surrounding environment. This study aims to analyze the motives and colors of "Sasirangan" as a source of biology learning in high schools and the knowledge of…

In this article, we describe curricular materials developed to engage undergraduate students in evolutionary thinking around antibiotic resistance using the MEGA-plate experiment (Microbial Evolution and Growth Arena). This elegant and visual experiment, developed by the Kishony Lab, shows the development of antibiotic resistance on the timescale…

The construction of scientific explanations is recognised by science education researchers and curriculum developers as one of the core epistemic practices in which students should acquire proficiency. However, little is known about the knowledge and skills that teachers must and do put into practice to successfully engage their students in…

Background: Science teachers' understanding of the roles of computing practices in science frame how they enact scientific computational practices in their teaching and how their students perceive the relationship between computational practices and scientific endeavours. Objectives: This critical, integrative review synthesizes teacher learning…

Graduate students in STEM fields undertook a 9-month training program focusing on practice-based development of active teaching methods. As instructors of record in their own senior-level courses, these trainees were observed on their independently designed classroom sessions using the COPUS classroom observation tool. Compared to a large sample…
