Taber, Keith S. – Chemistry Education Research and Practice, 2013
Much scholarship in chemical education draws upon the model of there being three "levels" at which the teaching and learning of chemistry operates, a notion which is often represented graphically in terms of a triangle with the apices labelled as macroscopic, submicroscopic and symbolic. This model was proposed by Johnstone who argued that…

Hartwell, Supaporn Kradtap – Chemistry Education Research and Practice, 2012
A number of scientific articles report on the use of natural extracts from plants as chemical reagents, where the main objective is to present the scientific applications of those natural plant extracts. The author suggests that natural reagents extracted from plants can be used as alternative low cost tools in teaching chemical analysis,…

Crippen, Kent J.; Brooks, David W. – Chemistry Education Research and Practice, 2009
The case for chemistry instruction based on worked examples is presented, using a contemporary model of human learning. We begin by detailing human cognitive architecture and outlining the Interactive Compensatory Model of Learning (ICML). Through the ICML, the role of motivation, deliberate practice and feedback are detailed as key variables in…
