Creating Digital Learning Objects to Introduce Grade 5 Students to the Nature of Models and the Particle Nature of Matter
World Conference on Educational Media and Technology 2013 (Jun 24, 2013) p. 2034
This session reports on a series of five digital learning objects (DLOs) created by the presenters to introduce Grade 5 (ages 10-12) students to the nature of models, the particle nature of matter, and particle explanations for physical change. ...
Guiding Age 10-11 Students to Notice the Salient Features of Physical Change Models in Chemistry Digital Learning Objects
Journal of Computers in Mathematics and Science Teaching Vol. 34, No. 1 (January 2015) pp. 5–39
This paper focuses on one Grade 5 class (9 females; 9 males) who worked in student-pairs to view five digital learning object (DLO) lessons created by the authors and meant to introduce students to the nature of models, the particle nature of matter,...
Using Digital Learning Objects to Introduce Students to the Nature of Models and the Nature of Matter
Journal of Computers in Mathematics and Science Teaching Vol. 30, No. 4 (October 2011) pp. 355–387
This article reports a subset of findings from a larger study centered on designing a series of six digital learning objects to help Grade 5 (age 10-12) students begin to consider the nature of models (understood as the physical or mental...
Scientific Visualisations for Developing Students' Understanding of Concepts in Chemistry: Some Findings and Some Lessons Learned
Teaching Science Vol. 60, No. 1 (March 2014) pp. 30–38
Scientific visualisations such as computer-based animations and simulations are increasingly a feature of high school Science instruction. Visualisations are adopted enthusiastically by teachers and embraced by students, and there is good evidence...

Journal of Chemical Education Vol. 94, No. 8 (2017) pp. 1027–1035
As one approach to moving beyond transmitting "inert" ideas to chemistry students, we use the term "teaching from rich contexts" to describe implementations of case studies or context-based learning based on systems thinking that ...
