TelKart and QnA: An Open Teaching System for Computer Science Courses
Download as PPTX, PDF1 like441 views
This document discusses an open teaching system called QnA and a custom hardware system called Telkart for creating course content. QnA is a software portal for uploading instructions and assessments that was designed using user research. Telkart is a cart with a Mac Mini, tablet, and recording equipment that allows instructors to create and live stream videos. The researchers demonstrate a prototype of a low-cost version of Telkart using an iPad and laptop. They seek feedback on their system and future work including open sourcing the software, evaluating and deploying the low-cost hardware prototype, and adding documentation to facilitate adoption.
TelKart and QnA: An Open Teaching System for Computer Science Courses
- 1. Telkart and QnA: An Open Teaching System for Computer Science Courses Vikram Kamath Cannanure, Dr. Geoff Gordon Carnegie Mellon University
- 2. Introduction: What’s the talk about? • Discuss our system for teaching computer science courses. • Show a prototype and its application in teaching. • Seek feedback about our system and it’s application in OER. • Look for prospective collaboration for research and deployment. 2
- 3. Our System: What is it made of? • QnA: A software system to upload instructions (videos, text) and assessments. • Telkart: A custom hardware system to create videos. • Lightweight: Uses existing devices (MacBook and an iPad) to create course content. 3
- 4. QnA: Software Web Portal • Limited Learning Management System(LMS) features with low setup cost. • Modularity, portability were the goals. • Designed using user-centered research; and open source libraries. 4
- 5. Our Design Approach • Our users are stakeholders • Features developed in iterations • Continuous feedback loop • We use insights from users for iterative design 5
- 6. Features in QnA • WYSIWYG- What You See Is What You Get • Real-time latex preview • Embed media • Version control 6
- 7. TelKart: Custom hardware cart • Mac Mini, Wacom tablet, video and audio recording. • Mounted on a custom-made cart. • Can be wheeled to a classroom or office. • Content is exported or live streamed to YouTube or Panopto 7
- 8. Future Work: Low Cost TelKart • iPad Pro and a MacBook connected using the default cable • Uses QuickTime and open source OBS Studio to broadcast the window from the iPad • Allows switching windows and adding a camera view. Add image 8
- 9. Demo 9
- 10. Next Steps: Low Cost TelKart “ It took me less than an hour to set up” - Professor, Carnegie Mellon University • Collect feedback from users and deploy it • Build a low cost version e.g. Android tablet • Build a DIY instructional setup for instructors to use it independently • Augment the system with 3D printing and add on lenses 10
- 11. Project: Future Work • Open-source software to form independent instances • Prototype and evaluate the low cost version of the tool • Deploy to more instructors within and outside university • Add documentation to make adoption easier 11
- 12. Summary • QnA: system is deployed in campuses in Pittsburgh and Silicon Valley. • TelKart: A custom hardware system to create videos. • Prototype a low-cost version of the system based on a laptop and a tablet • Seeking feedback and ideas that you may have 12

Editor's Notes
- #3: Hardware and software
- #5: Instructions: Videos, Assessments: Multiple choice, This is what you can do in the software. Examples of Media course: tie it in with piazza, blackboard, Piazza
- #6: USer centric users; different types of users; Students TAs and Profs Bridging the gap, what specifically you track. Change the content of the flowchart Having specific things for user activity (doing differently)... fully user 6 courses.. 500 users
- #7: WSWIG: Drag and drop Open source libraries and user centric approach: Added instructional design hints e.g immediate feedback Version control, LaTeX for equations, rich text editing, and embedded media. Data loss - we had backups
- #8: Summary of the slide ~7k Use stuff they already have. Limitations: Logistics
- #9: Key strokes matter…. In language Booking in University of Hawaii and University of Michigan Variablity. In the world, technology limitation
- #12: Adding
- #13: Cabinets; wireless; support system for What panopto: -- open source -- How can it be used in Open education.
