The Context• How can critical reflection be embedded into
computing modules?• How can we help students to evidence, document
and communicate the results of their learning over time?
• One approach is through reflective videos
![Page 4: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/4.jpg)
Our Research• To what extent can reflective videos help develop an
awareness amongst students of the importance of transferable skills, as well as subject specific technical skills, from an early stage of their degrees?
• To what extent do students themselves accept the medium of video as a means of critical reflection?
• Longer term – peer mentoring opportunities for reflective videos?
![Page 5: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/5.jpg)
Today’s Talk• Stage 1: Results of an online survey examining
current reflective practice amongst Scottish computing students
• Stage 2: Results from a student workshop, and from embedding reflective videos within a specific module
• Stage 3: The design and development of the “Let Me Demonstrate” application
![Page 6: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/6.jpg)
Stage 1: Online Survey• Digital technologies can often be used for personal
development planning (blogs, social networking tools, video sharing websites)
• Problem: Activities are often conducted in the student’s own time (so we might not know about it)
• To what extent do computing students across Scotland undertake such activities outside organized classes?
![Page 7: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/7.jpg)
Data Collection• Respondents’ background information• The extent to which respondents currently consume
and contribute to online and offline learning resources (and why)
• The extent to which respondents would be comfortable contributing to activities relating to their learning (e.g. keeping a blog)
![Page 8: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/8.jpg)
Results – background information• 284 responses (78.2% male, 21.8% female)
• 77.8% of respondents were 18-25 years old
• 81.3% of respondents were undergraduate students, more or less evenly split from year 1 to year 4
![Page 9: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/9.jpg)
Results – current activities• 110 respondents (38.7%) provided assistance
through Q&A sites such as StackOverflow and Yahoo! Answers
• 44 respondents (15.5%) ran their own computing-related blog
• 28 respondents (9.86%) uploaded computing-related videos to video-sharing websites
![Page 10: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/10.jpg)
Results – current activities• Reasons for undertaking such activities (in order):– To improve future employability prospects– To develop their self confidence in a subject– To be able to reflect on what they have learnt…– Financial rewards– Because a classmate/friend does so
![Page 11: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/11.jpg)
Results – preferred activities• Most popular:– Responding to a query on a forum – Running a blog
• Least popular:– Running a podcast
![Page 12: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/12.jpg)
Possible Barriers• Perceived fragility of knowledge:– “I’m not skilled enough to contribute”– “I would not be comfortable presenting myself as
an ‘expert’”• Required effort:– “Many of the tasks would be quite time
consuming, and that would be the constraining factor”
![Page 13: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/13.jpg)
Stage 2: Use of Video• We evaluated the potential for video-based reflection in
two separate stages: – A three-hour workshop session (discussed elsewhere)– A semester-long evaluation
• Aims of this stage:– To investigate the extent to which students accept the
medium of video as a means of critical reflection– To investigate the extent to which videos could
possibly develop their transferable skills, as well as subject-specific technical skills, from an early stage of their degrees
![Page 14: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/14.jpg)
Semester-long Evaluation• Conducted as part of a 1st Year, Physical Computing
module• In groups, students were encouraged to create blogs
embedded with video demonstrations of their learning progress throughout the semester
• Preliminary lab sessions on video creation were provided
• This activity was not assessed – it was entirely voluntary
![Page 15: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/15.jpg)
Results• 57 videos were produced • Production tailed off towards the end of the
semester• However, production “spiked” in the middle due to
the pressure project (when students wanted to show off their achievements)
• Example videos can be found on the project website: http://lmd.computing.dundee.ac.uk/?page_id=171
![Page 16: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/16.jpg)
Student Feedback• Positives:– Students enjoyed sharing their videos not only with their
classmates, but also family and friends– Students also benefited from watching each others’ videos– Video production brought them together as a group– Videos became reference tools for revision
• Negatives:– Technical constraints– Hearing one’s own voice– Some students struggled to see the point of the exercise
![Page 17: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/17.jpg)
“Let Me Demonstrate”• An internal, student-driven, video-based proof of
concept application running on a School of Computing server
• Allows students to share their reflective videos in a safe and secure environment
• Students contributed significantly to the design process
• Source code is available to other institutions on request
![Page 18: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/18.jpg)
“Let Me Demonstrate” • Allows students to upload, tag, and comment on
videos• Protected behind a firewall to prevent non-students
from accessing the system• Designed to be accessible to as wide a range of users
as possible• Designed using a “responsive” layout – the interface
changes based on whether the user is on a laptop, a desktop or their smartphone

Technical Challenges• We have yet to evaluate the app with our students
due to numerous technical issues• Most of the issues relate to video uploading and
conversion• Videos cannot be played back in certain browsers,
including the Safari browser• We are currently looking into potential solutions
prior to deploying the application “in the wild”
![Page 21: Welcome. Let Me Demonstrate: Towards a Web-based Application to Encourage Critical Reflection amongst Computing Students](https://reader035.vdocuments.us/reader035/viewer/2022062312/551ae8bd55034606048b5cf1/html5/thumbnails/21.jpg)
Future Work• An evaluation of the application with School of
Computing students in 2013-14 • Investigate the potential peer-mentoring effect of
reflective videos in computing• Compare and contrast video reflection with other
methods of critical reflection, e.g. blogs, portfolios• Applying the system outside the context of
computing
