Using a virtual microscope to increase students’ access to and identification of microscope slides, Dr Catherine Gorrie’s project is extending conventional microscopy learning in Science courses.

What the project is about

Dr Gorrie is developing an online ‘virtual microscope’ to provide students with a resource tool for use prior to and after laboratory classes and lectures in Histology. Students will be able to, for example, compare and review the virtual microscope slide images with those viewed looking down the actual microscope in their laboratory class.

Why the project is being introduced

Students’ access to microscopes is limited outside laboratory class. This project will therefore support and enhance current curriculum by providing students with a ‘virtual microscope’ they can access from home to identify, revise and develop understanding of histology-related ideas. It will also provide greater opportunities for students to work together, discuss and test out their ideas.

How the project is being implemented

The ‘virtual microscope’ is being implemented through the SPARKplus system. Dr Gorrie has developed each module on SPARKplus  to cover one topic and take 10-20 minutes to complete. Students are provided with online assistance via a brief introductory tutorial explaining the SPARKplus system, how to access the images and complete the modules. Students use the system to provide and receive immediate feedback through images, questions and comments.

Based on her students’ completion of the online modules, Dr Gorrie is able to review which parts of the histology slides they understood or didn’t quite grasp. She then targets the trouble area(s) in that week’s lecture and practical class, instead of repeating already understood concepts or other content.

Having access to slides is difficult in Histology, with only one student at a time being able to look through the microscope in class. Dr Gorrie’s virtual microscope changes this by allowing any student to instantly view any of those slides from home. Based on their familiarity with those ‘digital slides’, students can now also work in groups to easily discuss what is being looked at under the microscope in their laboratory classes. One student noted the benefits of, the ‘virtual microscope’ in this way: it “helped me in preparing what to look for in the next day’s lab class as I’m always unsure of what to look for during pracs”.

Challenges and considerations

Initially, the quality of the images under the 'virtual microscope' needed improving to increase clarity for analysis and identification. This problem was solved, and now Dr Gorrie is looking at having a zoom function developed.
 

Dr Gorrie recommends not only spending time on presenting new and novel concepts to the students but also considering how to use other resources to guide that conceptual development and increase their participation:
 

"I think I expected students to embrace this from the start and some did, but I think many were just bewildered, especially as it was not assessed. I have a better idea of how this software works now, and will be able to develop and integrate everything for students better next year."
