Welcome What? Why? How?
Chemistry 125 vs 126?
CHEM.125/126: - Co-requisites with identical work and grades. - One credit each for a total of two credits. - Credit for TWO inorganic lab courses.
WAIT LISTS AND OVERRIDES:1500 chem. (Heonia Hillock; [email protected];734- 647-2858)
Course Information
• An independent introductory chemistry course• Consists of lecture, laboratory and discussion
components.• Labs and discussion on a given topic occur
after pre-lab lecture.• Instructors for lab and discussion are GSIs.
Course Format• Pre-lab lecture ( 1 hour) 1 - 2 pm Tuesdays or
Thursdays in 1800 chem)• Discussion (1 or 0 hour)• Laboratory ( 2 or 3 hours)
Discussion and lab and lecture time:• Labs are 3 hours when discussion is NOT held;labs are two hours on days discussion is held• Discussions occur AFTER the completion of alab experiment topic
Lab Makeups
• To earn points all labs must be performed.• If two labs are missed contact the course
coordinator for permission to stay in the course.• Makeups may be arranged with home GSI to be
performed in his/her other section
Lab Makeups
• Makeups may be arranged in any section byemailing the makeup site as indicated in the labmanual, p.226.
• When arranging a time/day for a makeup becognizant of the lab days and lab week schedule:
Thursdays Fridays Tuesdays 8 - 11 8 - 11 11 - 2 11 - 2 11 - 2 2 - 5 2 - 5 2 - 5

Chemistry 125/126 Grading
• Points reward individual and team efforts.• Labs must be performed to earn points.
Team % points 54 %Individual % points 46 %
Chemistry 125/126 Grading
Team Points. (54%)Team lab reports and discussion presentations.
Note that the lab report form is merely an outline.For maximum points respond to all directivesand questions in the experiment and refer tothe data to support your conclusions.
Individual Points. (46%) Pre-lab reports. Hourly I and Hourly II exams. Peer points.
Winter 2008 course letter grades:At least an A- 450 pointsAt least a B- 400 pointsAt least a C- 350 pointsAt least a D- 300 points
Chemistry 125/126 Grading
Point grade cutoffs guaranteed.• Points needed for a particular letter grade will not beincreased but may be lowered.• Cutoffs lowered if some aspect of grading is notequitable to prior terms.

Methods fueled by concern about whatstudents can do with the skills they learnlater on in life and student learning research.
CHEMISTRY 125/126
• Develop life long skills (Thinking (data analysis),team work, oral communicationskills…)
• Understand core concepts (Emphasize process rather than content or memorization)
Individual → Team
Traditional → Inquiry
→ Technology assisted
Boyer Commission Report: Carnegie Foundationfor the Advancement of Teaching (1998 & 2004)
Alter classroom methods:
“Many undergraduates graduate without knowing howto think logically, write clearly, or speak coherently”
Why Teamwork?
• Students differ in thinking and processing skills..
•Teams with members of diverse abilities are morecreative and via dialogue understand moreand via dialogue understand more..
• The techniques and skills often emphasizedare not skills most students need later on inlife, except for chemistry majors.
• Labs are often very descriptive and virtuallyeliminate all requirements for student thought
TRADITIONAL LAB
“The student is expected to produce a verification ofsomething that he already knows, and so ends uptrained to ask what a result is supposed to be, notwhat in fact it is” Miles Pickering
Inquiry Lab (chem.125/126)
The labs developabilities to explore,analyze, and visualizedata. The ultimate goalis to enhance students’abilities visually depict adata pattern that is easyto observe and tounderstand theimplications of the data.
CHEM. 125/126↓
Goal: Visualize and Analyze data during lab.
• Collaborative Team research.• Teams investigate different (rather than identical) samples and/or conditions.*• Technology assisted data collection and analysis.
* See lab manual, page 216 for Winter 2008 teamexperiment assignments.

• CoLABnet data may be transferred to Excel for dataanalysis• Data is available in lab and on the course website:http://www.umich.edu/~chem125 .
Boyer Commission Report: Carnegie Foundationfor the Advancement of Teaching (1998 & 2004):
“Undergraduate education must enable students toacquire strong communication skills, and therebycreate graduates who are proficient in both written andoral communication.” (Chapter V)
Teacher → Studentcentered centered
Teacher (rather than the student) becomes highlyskilled -- Teacher writes, speaks, consults, organizes,and solve problems.
Topic content often emphasized rather than process.
TEACHER CENTERED DISCUSSION
“blah, blah, blah, blah”
“How many grams of sulfuric acid areproduced annually in the U.S?…?”
Chem.125/126 Discussion
Student Centered Discussion• Teams’ solve assigned problems in lab.*
• Teams’ orally present results in discussion.
* See page 216 of the labmanual for Winter 2008 teamdiscussion assignments.
