Acknowledgments
• Dr. Alejandra Uranga, co-‐instructor of 16.101x
• Savithru Jayasinghe, graduate TA of 16.101x
• Undergraduate TAs of 16.101x
• MITx for financial and general support

Outline
• Structure of 16.101x Introduc9on to Aerodynamics
• Outcomes-‐based MOOC
• LaTeX-‐driven edX MOOC development

Rela?onship to MIT subjects
• Undergraduate aerodynamics on campus taught in: – Sophomore core subject Unified Engineering (~12 units) – Junior/senior elec9ve subject: 16.100 Aerodynamics (12 units)
• 16.101x: – Overlaps with Unified and 16.100 – But without project-‐based learning
• Plan to u9lize 16.101x material in Unified and 16.100

Structure of 16.101x Module
• Notes: – Embedded ques9ons for checking understanding – Solu9on videos (tablet-‐based) provided – Occasional short (tablet-‐based) “lecture” videos
• Homework problems: – More challenging than embedded ques9ons – Solu9ons videos provided a[er due date.
• Sample problems: – Same level as homework problems – Solu9on videos provided
• Discussion forum 6
Embedded questions: 5-10 Homework problems: 2-3 Sample problems: 2-3 “Lecture” videos: 2-4 Videos per module: 11-20 Videos in total: ~185

Demo of 16.101x Module Content
• Give a live demo of 16.101x module content • Show notes, embedded ques9ons, solu9on videos, “lecture videos”, homework problems, …
• Ini9ally do not point out/discuss MOs
10
Demo of 16.101x M.O.
• Give a live demo of M.O. capability • Start by showing an Overview sec9on of a module with the M.O. list
• Then show how all content (notes and problems) are labeled by M.O.s (and show hover technique)
• Then click on M.O. to reveal M.O. index

LaTeX-‐based development process
• LaTeX is a document prepara?on system and markup language • Tradi?onally LaTeX is used in academia for preparing books, journal ar?cles, and lecture notes • From text source, a PDF is generated according to specified styles • Some advantages include ease of re-‐use; sec?on, equa?on, and figure referencing; hyperlinks; etc.
16
LaTeX-‐based development process
• LaTeX2edX is a python-‐based soWware u?lity that produces edXxml from LaTeX source • Course content is developed in a convenient and well-‐known form (i.e., LaTeX) • Content developers are insulated from the complexity/nuance of html/xml in the edX pla[orm • Easy to re-‐use content and generate PDFs for offline development and viewing • Conversion process is automa?c permi]ng genera?on of MO Index, MO labelling, figure and equa?on pop-‐up references

Future Plans
• U9lize 16.101x resources for on-‐campus subjects
• Improve edX support of outcome-‐based MOOCs
• Encourage LaTeX-‐driven development of edX classes
