What is ChemTube3D?
ChemTube3D is an interactive, freely available, resource providing 3D simulations and animations modelling the structure and reactivity of many important chemistry molecules. The resource is mainly aimed at undergraduate students.

Who uses ChemTube3D?
• Students
Promotes understanding
Open ended investigation possible
Guided learning approach possible
Positive comments from students about how useful the resource is to them
• Tutors/Lecturers
Use as a teaching aid in lectures
Teach students how to use the resource
Since the launch of ChemTube3D in December 2007 there have been over 270,000 visits to the resource from people all around the world.
iChem3D project
• Jointly funded by JISC and the University of Liverpool
• Investigate the current use of ChemTube3D
• Generate new, freely available, learning designs for ChemTube3D
• Produce guidelines for using ChemTube3D

“Action mazes can be used for many purposes, including:
• problem-solving,• diagnosis,• procedural training and• surveys/ questionnaires”1
A tool for creating Web-based action mazes

A tool for creating Web-based problems
Allows you to “create interactive:• multiple-choice, • short-answer, • jumbled-sentence,• crossword, • matching/ordering and• gap-fill exercises
for the World Wide Web.”2
Our use:Multiple choice self-assessment activities

“the graphics are very useful”
“I think the stepwise approach is very valuable: too often, they rush through protonation/ deprotonation steps (especially!) without enough thought”
“I like the step-by-step approach in your new format for beginning students”
“I like it!!”

• Students were shown a demonstration of using ChemTube3D
• Followed by a demonstration of the new step by step approach
• They were then asked to provide answers to the question using the electronic voting system

Response
Would you use more of the new self-assessment activities?
(44 responses)
• Based on a step by step mechanism relevant to their course
• Students were briefly shown an example of the new self assessment activities and were
then asked to comment
Conclusions
