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. (Beverly Lange; [email protected];734- 647-2858)
Course Information
• An independent introductory lab-centeredcourse with lecture and discussion components
• Labs and discussion on a given topic occurafter pre-lab lecture.
• Instructors for lab and discussion are GSIs.
Course Format• Pre-lab lecture ( 1 hour) 10-11am, 1 - 2 pm
Tuesdays; 10-11 am 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
Required Materials
Lab Manual:Collaborative Investigations in Chemistry,Nancy Konigsberg Kerner and JamesPenner-Hahn, Hayden McNeil Publishing,Inc., Fall 2008 edition.

Lab Makeups
• Labs must be performed to earn points.• 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• To makeup a lab, follow the directives on pp. 237-
238 in your lab manual
Lab Makeups
• When arranging a time/day for a makeup becognizant of the lab days and lab week schedule:

Chem. 125/126 Goals and Methods
• Students do NOT intend to be chemists!
Student goals and background?
Methods fueled by concern about whatstudents can do with the skills they learnlater on in life and student learning research.
CHEMISTRY 125/126 Methods
• Develop life long skills Data analysis, team work, oralcommunication skills…)
• Understand core concepts Emphasize process rather than content or memorization
Traditional → InquiryIndividual → Teamwork
Teacher-centered → Student-centered→ Incorporate technology
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”
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 is” Miles Pickering
Chem.125/126: Guided Inquiry Labs
Collect data Interpret data Apply concept into solve a problem formulate results a new setting
E I AExploration Concept Invention Application
Guided Inquiry Strategy and Learning
“To develop learning competence studentsmust understand facts and ideas in thecontext of a conceptual framework”
—— BransfordBransford, Brown, & Cocking, Eds., Brown, & Cocking, Eds.How People Learn: Brain, Mind, Experience, and SchoolHow People Learn: Brain, Mind, Experience, and School..
Chem.125/126: Teamwork
• Learning is a social activity• Social interactions can help students build theirknowledge base, monitor their progress, and clarifytheir understanding (and misunderstanding)
Why Teamwork?
• Students differ in thinking and processing skills..
• Social interactions reveal differences and result inlearning by restructuring of students knowledge..
Chem.125/126:Technology assisted data collection and analysis
• Collaborative Team research.• Teams collect data for different (rather than identical) samples and/or conditions.*• Technology assisted data collection and analysis.
* See page 227 for Fall 2008 team experiment sampleassignments.
CoLABnet
CoLABnet
• 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 → Student/teamcentered centered
Teacher (rather than the student) becomes highlyskilled -- Teacher writes, speaks, consults, organizes,and solve problems.
TEACHER CENTERED CLASSROOM
“blah, blah, blah, blah”
“How many grams of sulfuric acid areproduced annually in the U.S?…?”
Chem.125/126: Team-centered lab and discussion
• Teams’ solve assigned problems in lab.*• Teams’ orally present results in discussion.• Questions address concept invention and application
* See p.227 for team assigneddiscussion questions.
Student Success in chem.125/126
The inquiry format and team work does NOT• insure an A in the course• insure concept invention and/or student learningand understanding.
YOU (the student) need tomake tactical decisions!
Student Success in Chem.125/126
• Choice of tactics must be appropriate.
Student Success in Chem.125/126
• Come prepared to lab• Invest in your team efforts and social interactions
- “Compare and discuss your observations with others.”- “Compare and discuss your data with others.”- “Compare and discuss the different team results for data patterns.”
