About SI for this Course

Supplemental Instruction is provided online via WebEx during the period of online classes. Join my SI sessions by using this link: https://iastate.webex.com/meet/sebeard




Due to potential unforeseen obstacles SI Leaders may encounter as they move to online delivery, some sessions may be modified, cancelled, or suspended.



Trying to learn physics can be a daunting task. Through SI, I will try to help you learn in bite-sized chunks throughout the semester so you can learn with less stress. In sessions, I will generally give you plenty of opportunities to work on problems you might see on an exam so you can be in that mindset early on. Since instruction has moved online, I will post an answer key following every session.

If you wish to contact me at any point, please use the "Contact Your SI Leader" link in the menu on my webpage.

Happy studies! I hope to see you throughout the semester.

Announcements

Online Instruction

Hello all!
Like you all, I am trying to work my way through shifting to online instruction in classes as well as in SI. I have a few general changes in policy I would like you all to be aware of for my future sessions:
1. All sessions will be held through Webex through the end of the semester (Day and time will not be changed)
2. Worksheets will be posted the day before their respective session
3. Answer keys will be posted on completion of respective session
4. Please use the Webex chat to sign into session with University ID number or netid
As always, if you have any questions or concerns, feel free to contact me through my SI page.
