Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

This paper describes the integration of geographic information system (GIS) technology in a high school environmental science classroom, specifically examining the impact of GIS technology on student engagement, critical thinking, and interdisciplinary learning for Education for Sustainability (EfS). This environmental science classroom utilized…

This case study aims to investigate the effectiveness of an online science enhancement program in retaining ethnic minority students in science by providing them with opportunities to interact with cultural role-models of scientists and engineers during the COVID-19 pandemic. The study draws on foundational theories of identity formation and…

Fostering methods that promote learners' conceptual understanding is crucial for better performance in science subjects. This study investigated how teachers of physical sciences perceive the utilization of Concept Cartoons as a formative evaluation tool. Ten Grade 11 teachers selected from secondary schools in the Nelson Mandela Bay district of…

The significant facet of Science Education is to make Science relevant in Students' learning. This involves the ability to draw in examples from daily contexts, to begin with, the learning or to apply concepts learned into familiar everyday phenomena. The main purpose of this study was to find out the relationship between the scientific…

It is common for high school physics teachers to comment on the challenges they face in supporting students' graph drawing skills, knowing their importance for the study of physics. This paper suggests a novel and alternative way to support students to develop their graph drawing skills as well as teach them about sound, frequency, and amplitude.…

The Advancing Science and Engineering through Laboratory Learning (ASELL) for Schools program has been instrumental in getting schools across Australia to reconsider the effectiveness of the laboratory learning activity (LLA) in science education. In Victoria, the ASELL for Schools project has collaborated with another nationally funded program,…

The focus of this article is to expand María del Mar Aragón, José Antonio Acevedo-Díaz and Antonio García-Carmona's paper "Prospective Biology teachers' understanding of the nature of science through an analysis of the historical case of Semmelweis and childbed fever" by focusing on the discussion about teaching non-epistemic aspects of…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

A versatile experiment is described for the high school and college laboratory setting based on the synthesis of biobased polymers prepared from inexpensive, renewable, and nonhazardous chemicals. Combinations of readily available citric acid, glycerol, and tapioca root starch are used to prepare three polymeric materials with different observable…

The illustration characteristics of 221 visual representations (VRs) of submicroscopic particles in nine Greek secondary chemistry school textbooks from the last three decades were analyzed. This analysis was done to develop a taxonomy that could help science teachers and curricula designers evaluate the efficacy of such characteristics on student…

The aim of this study is to investigate the relationship between high school students' understanding of carbon compounds, including their transformations, and their ability to trace matter in the carbon cycle. The rationale of this study is based on the hypothesis that the students' lack of knowledge about carbon compounds and their…

Chemistry plays an important role in developing scientific theories to describe, explain, and predict the physical world and to produce useful products for improving quality of life throughout history. To arouse student awareness of the value and importance of learning chemistry and becoming chemistry literate, we propose an application of systems…

The use of the valence-shell electron-pair repulsion (VSEPR) model is essential for understanding aspects of bonding, molecular dipoles, inorganic complex ions, isomerization and stereochemistry, the lock-and-key mechanism for enzyme activity, and many other ideas. This paper describes how different approaches can be used to help students learn…

This paper focuses on the procedure and results for analyzing text-difficulty in lower-secondary chemistry textbooks in the Czech Republic. The authors use established methodology for text-difficulty analysis by Nestler, adapted by Prucha and Pluskal by adding a second independent analyser to improve reliability. Some textbooks do not follow the…
