This paper describes the utilisation of a technology-facilitated professional learning network (PLN) for pre-service teachers, centred on chemical demonstrations. The network provided direct experiences designed to extend their pedagogical content knowledge on demonstrations in Chemistry teaching. It provided scaffolded opportunities to…

This project utilizes visual and critical thinking approaches to develop a higher-education synergistic prelab training program for a large second-year undergraduate analytical chemistry class, directing more of the cognitive learning to the prelab phase. This enabled students to engage in more analytical thinking prior to engaging in the…

This article presents a demonstration using methane bubble flame tower that offers a fun and relatively cheap way of demonstrating what happens when there is a density difference. Teachers can do this as a predict-observe-explain demonstration after the students have learned about density to extend their learning and get into some higher order…
