1 Chemistry 1050 Discovering Chemistry A year of Discoveries, experiences, and upcoming challenges

2 Chem 1050 Introduced in 2008 – Single stream: replaced both Chem 020 and 023 – Builds on Grade 12 chemistry – Fewer calculations and more thinking – Less bubbling and more writing – Course workbook – Plenty of free assistance available

3 Building on Grade 12 Chem... Assumes knowledge of fundamental material – Masses, moles, and molarity – Balancing reaction equations – Limiting reagent – Strong acids and bases (pH) – Reaction types (redox, precipitation, etc.) Most had no trouble, but some did not remember much from high school

4 Fewer calculations, more thinking... High school and Chem 020/023 −log([H 2 SO 4 ] − [NaOH]) = pH of solution Chem 1050 – Much more thought-oriented Explain why... What happens if... Consider... – Students had difficulties extending concepts punch in calculator that’s what the calculator gave me... it can’t be wrong

5 Less bubbling, more writing... Introduced a short-answer component to tests and exams in January of 2009 – Encouraged students to develop a coherent argument – Great for asking conceptual and thinking questions

6 – Allowed students to express their creativity – Short-answer worth 1/3 of midterm test or final exam – Marked by course instructors and TAs

7 Course workbook Hybrid of textbook and lecture notes – Students bring workbook to class Overall well-received by students – More time listening in class and less writing – Students asked to read relevant topics before class – No additional notes to print; lectures not posted Promoted uniformity between instructors

9 Course workbook Hybrid of textbook and lecture notes – Students bring workbook to class Overall well-received by students – More time listening in class and less writing – Students asked to read relevant topics before class – No additional notes to print; lectures not posted Promoted uniformity between instructors

10 New labs Video pre-labs – Very detailed (eliminated the need to read the lab manual beforehand) and long (good texting session) – New this year: shorter videos and more TA interaction Computerized stations were well-received New this year: video questions and semi- formal reports instead of fill-in-the-blanks

11 Free assistance... Plenty to choose from – Scheduled tutorials (optional, biweekly) – Resource Room (about 20 hours/week) – Residence and library TAs – WebCT discussion board Too much  underutilization of all of them – This year: no Resource Room and no res/lib TAs

12 Statistics... Sept enrollment1659 WDN and WDF101 Remaining1558 Average grade67.6 B 24% A 17% D 14% F 13% A+ 8% Identical to combined, weighted average of Chem 020 and 023

13 Chemistry in 2010–11 Chem 1050 to split into two half-courses – Same combined curriculum as Chem 1050 – Courses can be structured the same or differently e.g. perhaps no tutorials in second half – Greatest challenge: will students who wait a year or two before taking the second half remember that they learned from the first?
