Abstract Structure model sets for inorganic compounds are generally expensive; their distribution to all students in a class is therefore usually impractical. We have therefore developed a structure model set to illustrate inorganic compounds. The set is constructed with inexpensive materials: ping-pong balls, and snap buttons. The structure model set can be used to illustrate isomerism in coordination compounds and periodic structures of ceramic perovskites. A hands-on activity using the structure model set was developed for high school students and was well-received by them. Despite the concepts being slightly advanced for them, the students’ retention of the knowledge gained through the activity was tested a week after they completed the activity and was found to be relatively high, demonstrating the usefulness of the activity based on the structure model set.

Abstract Objective The application of molecular graphics software as a simple and free alternative to molecular model sets for introductory-level chemistry learners is presented. Results Based on either Avogadro or IQmol, we proposed four sets of tasks for students, building basic molecular geometries, visualizing orbitals and densities, predicting polarity of molecules and matching 3D structures with bond-line structures. These topics are typically covered in general chemistry for first-year undergraduate students. Detailed step-by-step procedures are provided for all tasks for both programs so that instructors and students can adopt one of the two programs in their teaching and learning as an alternative to molecular model sets.

The Rasch measurement principles espoused in the Bond & Fox (2001) volume reviewed elsewhere in this journal are routinely adopted by Australia's major educational measurement projects (e.g., by Australian Council for Educational Research, Educational Testing Centre). Yet those ideas are yet to have their full impact in smaller research projects in educational and developmental psychology. A number of quantitative analytical techniques used in our disciplines are able to help us to draw conclusions like “Betty is better than or more developed than Bob”, but Rasch measurement is uniquely placed to help us conclude that “Betty is this much better than or more developed than Bob.” In educational and psychological statistics, we regularly presume the “interval” nature of our research data, but only the Rasch model sets about to ensure that the units of measurement maintain their unit value across the whole achievement or development scale.
