1 Chemistry 125/126 Welcome What? Why? How? Nancy Konigsberg Kerner 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. (Betsy Waldrop; waldropb@umich.edu; ) Course Information An independent introductory lab-centered course with lecture and discussion components Labs and discussion on a given topic occur after pre-lab lecture. Instructors for lab and discussion are GSIs.

2 Course Format Pre-lab lecture ( 1 hour) 1-2 pm, Tuesdays and 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 a lab experiment topic Required Materials Lab Manual: Collaborative Investigations in Chemistry, Nancy Konigsberg Kerner and James Penner-Hahn, Hayden McNeil Publishing, Inc., Winter 2009 edition. Supplies: Lab Marking pens 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. Lab makeup may be arranged with home GSI to be performed in his/her other section To makeup a lab, follow the directives on pp in your lab manual

3 Lab Makeups When arranging a time/day for a makeup be cognizant of the lab days and lab week schedule: Mon Tues Wed Thurs Fri There are no labs on Mondays and Wednesdays The lab week runs from Thursday thru Tuesday DISCUSSION and LAB 1 DISCUSSSION ROOM (8-9 am or 11am - noon or 2-3 pm) Team Assignment Survey Form, lab manual, page 4 LAB ROOM (9-11 am or noon - 2 pm or 3-5 pm) Check-In Team Task Exercise, lab manual, pages 5-7 Team Task Schedule, E1-3, page 8 Safety and Scavenger Hunt, pages Pre-lab Prep and Schedule (Manual, page 234) Experiment Topics Check-in Safety Hunt Team Task Exercise Pre-lab lecture 1/13 (200 sect) 1/15 (100 sect) Pre-lab Reading Pages Lab Points

Chemistry 125/126 Grading Winter 2009 guaranteed course letter grades: At least an A- 450 points At least a B- 400 points At least a C- 350 points At least a D- 300 points Point grade cutoffs guaranteed. Points needed for a particular letter grade will not be increased but may be lowered. Cutoffs lowered if some aspect of grading is not equitable to prior terms.

CHEMISTRY 125/126 Methods Methods fueled by concern about what students can do with the skills they learn later on in life and student learning research. Develop life long skills Data analysis, team work, oral communication skills ) Understand core concepts Emphasize process rather than content or memorization

10 Boyer Commission Report: Carnegie Foundation for the Advancement of Teaching (1998 & 2004) Many undergraduates graduate without knowing how to think logically, write clearly, or speak coherently Alter classroom methods: Traditional Inquiry Individual Teamwork Teacher-centered Student-centered Incorporate technology TRADITIONAL LAB Labs are often very descriptive and virtually eliminate all requirements for student thought The student is expected to produce a verification of something that he already knows, and so ends up trained to ask what a result is supposed to be, not what in fact is Miles Pickering Chem.125/126: Guided Inquiry Labs E I A Exploration Concept Invention Application Collect data Interpret data Apply concept in to solve a problem formulate results a new setting

11 Guided Inquiry Strategy and Learning To develop learning competence students must understand facts and ideas in the context of a conceptual framework Bransford,, Brown, & Cocking, Eds. How People Learn: Brain, Mind, Experience, and School. Chem.125/126: Teamwork Learning is a social activity Social interactions can help students build their knowledge base, monitor their progress, and clarify their understanding (and misunderstanding) Why Teamwork? Students differ in thinking and processing skills. Social interactions reveal differences and result in learning by restructuring of students knowledge.

12 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 of the lab manual for Winter 2009 team experiment and discussion question assignments. CoLABnet CoLABnet Data is available in lab and on the course website: Boyer Commission Report: Carnegie Foundation for the Advancement of Teaching (1998 & 2004): Undergraduate education must enable students to acquire strong communication skills, and thereby create graduates who are proficient in both written and oral communication. (Chapter V) Teacher centered Student/team centered

13 TEACHER CENTERED CLASSROOM Teacher (rather than the student) becomes highly skilled -- Teacher writes, speaks, consults, organizes, and solve problems. blah, blah, blah, blah How many grams of sulfuric acid are produced 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 assigned discussion 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 learning and understanding. YOU (the student) need to make tactical decisions!

14 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.
