This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

This study aimed to determine the effect of using a virtual anatomy system (VAS) on student learning with regard to reproductive system with respect to the acquisition of misconceptions. This study used an experimental method by comparing the results of the class learning using virtual laboratory media with a control class. The result showed that…

Molecular imprinting technology holds significant potential for applications in chemical analysis and detection. In order to integrate the fundamental knowledge of polymer chemistry, electrochemistry, and analytical chemistry with practical applications and cutting-edge research, we proposed a comprehensive experiment of the preparation,…

Metabolism is always a challenging topic in biochemistry. In our project, a courseware called "Metabolism Metro" was developed. "Metabolism Metro" is a self-learning tool which aims to facilitate students learning of metabolic pathways in an interactive and easy-to-understand manner. The courseware includes both pre-class and…

The development and acquisition of science process skills (SPS) in science education are closely linked to the development of 21st-century skills and improvements in academic performance. To help facilitate the development of SPS in learners, teachers should acquire and exhibit SPS. This study assesses the SPS acquired by final-year students in a…

Although formulating a broadly accepted definition of scientific literacy may be challenging, it is widely recognized that Nature of Science (NOS) is an essential component of it. There are different ways to define NOS. In some cases, NOS can be conceptualized through a number of general NOS aspects like for instance science's empirical basis or…

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…

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…
