What is the best use of your time as a teacher?
• Lecturing?• Manual grading?• Discussion groups?• Posting to a blog?• Motivating?
What are your objectives?• Increasing the baseline understanding
of the average student?• Helping the best students actualize
their potential?

Student Response to Screencasting: Attendance

Student Response to Screencasting: Usage Patterns
•Some students get ahead and watch lectures several times•Some students wait for night before test and try to cram•Most students fall in between and appreciate a suggested timeline
•Podcasting/vodcasting an archived course not convenient•I recommend downloading a zip of all recordings safest•However with smartphones on demand Flash may be best

Best use of Class Time
Mainly repeating lectures
Mainly workshops
One-on-one mentoring
Doing problems
Games

WikisA wiki is a website that allows the easy creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor.
![Page 10: Philadelphia U Sciences 2011](https://reader035.vdocument.in/reader035/viewer/2022070303/549aa593b47959fc088b4574/html5/thumbnails/10.jpg)
Educational Uses of Wikis
•Organizing course content
•Student assignments
•Student generated content
•Easy to make content public and rapidly indexed on Google

Student Response to Class Wikis
•Some students do extra credit assignments (ChemSpider curation, multimedia component, Acawiki) and add resources•Some students do only the minimum required of assignments•Most students fall in between
Most students kept research logs and used feedback(reported progress/asked questions)
Almost all students used their real names

Student Response to Research Wikis
•Students appreciate rapid feedback via the wiki•Students learn to properly document experiments by using a research log•The use of Google Spreadsheet templates makes it easier for students to record data and others to verify calculations•For teaching lab based deployment sufficient structure must be given while still allowing students to think•Students appreciate being co-authors on a book and having a bio/pic included•Although interaction via wiki is invaluable, face to face meetings (or phone calls) are also very important
