Socio-scientific issues (SSI) instruction positions the understanding and practice of science in the context of issues that are informed by science but require reasoning about their societal dimensions to respond to those issues effectively. For this reason, instruction in the context of SSI has been considered the gateway to contemporary visions…

A major challenge when designing new experiments for the general chemistry laboratory is introducing students to the necessary techniques while keeping the experiment engaging and accessible. This work presents a new multiweek activity designed to introduce students to advanced instrumentation in the form of high-performance liquid chromatography…

Chirality continues to intrigue scientists because of its implications in various scientific areas, including the long-unsolved question of its development and link with the origin of life. Chirality plays a significant role in medicine with the advent of chiral drugs and the consequent importance of asymmetric synthesis. For many undergraduate…

Multiple perspectives on geographical thinking are lacking in the teaching of climate change in school geography. This study establishes an epistemic model through a co-construction design to support geography teachers' curriculum making with respect to climate change. We developed the preliminary model with four main geographical perspectives,…

An integrated laboratory experience in X-ray photoelectron spectroscopy (XPS) is designed for undergraduate and graduate students in chemistry, materials science, and other related fields. Focusing on ubiquitous Si, Cu, and their common oxides, students are guided to characterize a series of standard materials by XPS to understand the fundamentals…

Microfluidic-based ultramicroscale chemistry experiments involve the manipulation and consumption of reagents on a microliter or submicroliter scale in a microfluidic device. This article presents the pedagogical functions of microfluidic systems, including green chemistry education, stimulation of students' interest in learning about chemistry,…

This study aimed to investigate the effects of the applications conducted in the science center within the scope of the science lesson "Solar System and Beyond" unit of the 7th-grade students in the secondary school, on the perceptions of the students about the out-of-school learning environments (OSLEs). In the quantitative part of the…

A growing body of literature focusing on undergraduate biology education calls for students to engage in the ways of thinking, feeling, and doing that reflect those in which biologists engage. Such reform efforts suggest that learning is best fostered when students engage in practices, concepts, and scientific reasoning as they endeavor to explain…

Written examinations for laboratory courses fall short in testing students' technical skills, problem-solving abilities, and execution of experimental design. This has led to practical examinations growing in popularity, but examples for senior-level students remain scarce. Senior organic chemistry students are gearing toward independence to…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

In this study, the primary goal was to enhance the knowledge and awareness of 4th-grade primary school students regarding global pandemic diseases and methods of safeguarding against worldwide epidemic diseases which are socio-scientific issues. To achieve this goal, two activity modules tailored for 4th-grade students were created. These…

Laboratory work has been a common element of science courses at university level for around two centuries, but its practice has been criticised by scholars in the field and related stakeholders. Mainly on a rationale of financial justification and educational efficacy, more evidence for learning has been called for. The aims of this systematic…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Chile is home to most of the world's largest telescopes, and astronomy research is robust in the country. However, astronomy education in Chile is much less mature. As an effort to increase its quality and coverage, more astronomy K-12 teacher professional development (PD) has been offered in Chile in the last decade, but the results of these…

Action research (AR) has long been promoted as a way teachers can improve their practice and increase their understanding of their educational situations. In this article we examine the impact of AR on science teacher education through a critical review of the literature. We sought to identify the goals and purposes of the AR, its mode, and the…
