Great! You've worked through the first module and are keen to start the next.
But... you're ahead of me; Module2 isn't ready to go live just yet. Feel free to ask your TAs or Robin about your uncertainty analysis questions.
Robin would also appreciate your feedback on Module 1 and the related Alchemy questions. In particular, the idea is to replace the need to do uncertainty analysis in every lab report with having you work through a series of modules (likely 2 in CHEM325 and 2 in 345). Do you think this is better teaching of uncertainty analysis, and does it allow you to better learn it?
If you'll be in CHEM445 in 2018W session and are interested in how effective these modules are, consider the idea of working with Robin on it via a CHEM445 RLE project. Watch for project announcements in late August 2018.
