Outline• Context• Hypothesis• Research Methods• Findings• Future work
![Page 3: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/3.jpg)
Context• Modules offered globally as part of a qualification must
have a practical science component• Anecdotal evidence suggests a negative perception of
online practical science
![Page 4: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/4.jpg)
Context• Can we validate this anecdotal evidence?• Does experience of the module alter perception?• What lessons can we learn about our pedagogical
design?

The modules• Scientific investigations – 10 credits online only module• Investigative and mathematical skills in science – 30
credits – blended• Both globally available• 95.2% of enrolled students completed and 84.2% of
enrolled students passed

Investigative and mathematical skills in Science• Some printed books• Some online texts• OU Live (synchronous online tutorial)• Tutor-marked e-assessment• Computer-marked e-assessment• Tutor group forum

Scientific Investigations
![Page 8: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/8.jpg)
Hypothesis• There will be a shift in student perception about online
practical science after study.
![Page 9: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/9.jpg)
Research Methods• Email invitation sent to 100 students • 16 % response rate – all interviewed• Telephone discussion for 15 minutes pre and post study• Discussions recorded and transcribed
![Page 10: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/10.jpg)
Analysis: Grounded theory analysis with stages:• Open coding• Axial coding• Selective coding

Question areas• Online study• Practical science• Practical science studied online
![Page 12: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/12.jpg)
Responses
I’m not sure if I will feel like a real scientist
I would probably get more out of a face to face situation in a real laboratory
There is a lack of really nice
practical stuff, test tubes and a few chemicals

Responses
If I could choose, I would do residential schools instead
I wish we could have a hands-on laboratory session
Oh I really don’t want to do this but I have
to

Unexpected responses• Timings and coordination• Online discussions• Reliability of other students in collaborative work• Solitary nature of practical work
![Page 15: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/15.jpg)
Post study responses
![Page 16: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/16.jpg)
Criticisms of methodology• Self selecting group• Motivated by voucher• Honesty of response• Leading questions
![Page 17: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/17.jpg)
Continuing research• Scientific Investigations post-study interviews late April• Investigative and mathematical skills in Science post-
study interviews late May• Broader questionnaire planned for next S141
presentation starting in October.
![Page 18: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/18.jpg)
Quantitative approach• Aim to use the interview responses to inform
questionnaire design• Larger sample of students• Possibly higher response rate with questionnaire format
![Page 19: Student perceptions of online practical science Dr Victoria Nicholas Dr David Robinson Prof. Stephen Swithenby](https://reader035.vdocuments.net/reader035/viewer/2022062511/551ae2df5503466b6a8b5cc0/html5/thumbnails/19.jpg)
Broader perspective• The Open University has an ongoing strategy to remain
at the forefront of innovation in online distance learning.• Research should highlight student misconceptions about
practical online science and will inform the design of new modules.

Summary• Address hypothesis• Standard research methods• Diversity of responses• Key responses• Continuing research
