Dunn, Justin; Ramnarain, Umesh – Education Sciences, 2020
This study investigated the effect of interactive computer simulation-supported inquiry on South African grade 8 learners' comprehension of atoms and molecular structures. Two sample groups of 34 learners per sample group were used, one acting as a control group who were exposed to a teacher-directed pedagogy while the experimental group used…

Dale, Keith; Dale, Stephen G. – Teaching Science, 2018
The Australian Curriculum (n.d.) describes chemistry as having three interrelated strands, Science Inquiry Skills, Science as a Human Endeavour and Science Understanding. It also states "... the three strands of the Australian Curriculum: Science should be taught in an integrated way". This article will explore a model for integrating…

Newman, Karla – Journal of Chemical Education, 2018
Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…

Stavrou, Dimitris; Michailidi, Emily; Sgouros, Giannis – Chemistry Education Research and Practice, 2018
Introducing Nanoscience and Nanotechnology (NST) topics into school science curricula is considered useful for an in-depth understanding of the content, processes and nature of science and technology, and also for negotiating the social aspects of science. This study examines (a) the development of an inquiry-based Teaching-Learning Sequence (TLS)…

Sgouros, Giannis; Stavrou, Dimitris – International Journal of Science Education, 2019
This case study focuses on teachers' professional development in NanoScience and nanoTechnology (NST). In the context of a Community of Learners (CoL), in-service teachers in collaboration with science education researchers, nanoscience researchers and experts from science museums, developed a teaching module. This module integrates NST topics…

Campo, Daniel; Garcia-Vazquez, Eva – Journal of Biological Education, 2008
Reconstructing phylogenies from nucleotide sequences is a challenge for students because it strongly depends on evolutionary models and computer tools that are frequently updated. We present here an inquiry-based course aimed at learning how to trace a phylogeny based on sequences existing in public databases. Computer tools are freely available…
