Example of Student Role Card General Chemistry I 5 credits Monday Tuesday Wednesday Friday Recitation A (2 hours) Morning Lecture (1 hour) Mid-day Afternoon Thursday Lab A (3 hours) Lab B (3 hours) • first time teaching course • POGIL in Recitation sections • ~ 45 students, 20-25 per section Lecture (1 hour) Lecture (1 hour) Recitation B (2 hours) Activities Week 1 The Nuclear Atom (1) Week 2 Balanced Chemical Equations (28) Limiting Reagents (29) Week 3 Molarity (33) Oxidation Numbers (49) Week 4 The Ideal Gas Law (34) Week 5 Enthalpy of Atom Combination (31) Enthalpy Changes in Chemical Reactions (32) Week 6 The Shell Model I (4) The Shell Model II (5) Week 7 Photoelectron Spectroscopy (7) The Shell Model III (8) Week 8 Atomic Size (6) Week 9 Bond Order and Bond Strength (13) Bond Length and Bond Strength (14) Week 10 Lewis Structures II (15) Lewis Structures III (16) Week 11 Dipole Moment (22) Hybrid Orbitals (18) Weeks 12 & 13 Intermolecular Forces (26) Strengths • students liked working in groups • students met/talked to classmates • activities helped students understand concepts • recitations were less boring Areas for Improvement • confusion about the “right answers” • poor class discussions • Reflector role underutilized Insights • overall course grades=different instructor • ACS exam scores • better prepared for 2nd semester • 6 vs. 17-18 drops CY111 2005 %NC, 14.6 n = 41 %A, 9.8 %D, 4.9 %B, 36.6 %C, 34.1 CY111 2002-2004 %NC, 5.0 %D, 4.3 %A, 25.7 %C, 35.7 %B, 29.3 n = 140 General Chemistry II 5 credits Monday Tuesday Wednesday Thursday Friday Morning Lecture (1 hour) Mid-day Afternoon Lab A (3 hours) Lab B (3 hours) • taught course 4 years • POGIL in Recitations (5) • 30-35 students, ~15 per section Lecture (1 hour) Lecture (1 hour) Lab A (3 hours) Lab B (3 hours) Used for Recitation Activities Week 1 Rates of Chemical Reactions I (36) Rates of Chemical Reactions II (57) Week 2 Equilibrium I (37) Equilibrium II (38) Week 7 Relative Acid Strength (46) Acid/Base Strength of Conjugate Pairs (47) Week 9 The Solubility Product (41) Week 12 Redox Reactions (48) Organic Chemistry I 5 credits Monday Tuesday Wednesday Thursday Friday Morning Lecture (1 hour) Mid-day Afternoon Lab (3 hours) Lecture (1 hour) Recitation (3 hours) • taught course 7 years • POGIL replaced traditional lectures & Recitations • 20-25 students Lecture (1 hour) Activities Lewis Structures (2) Resonance Structures (3) Acid-Base Reactions (8) The Core Charge Effect and Inductive Effect (9) Resonance Effects (10) Electron Orbitals (11) Conformers of Carbon Structures (4) Chirality (7) One-Step Nucleophilic Substitution (12) Two-Step Nucleophilic Substitution Reactions (13) Elimination Reactions (14) Stereochemistry of E2 Reactions (15) Hydroboration/Oxidation (22) Physical Chemistry I & II 4 credits each • three 1-hour lectures, one 3-hour lab • instructor taught for many years • POGIL replaced traditional lectures • 7 students Two teams: 3 and 4 students Teams worked through activities separately Entire class participated in discussion Activities First Semester Gases I (G1) Gases II (G2) Work (T1) The First Law of Thermodynamics (T2) Enthalpy (T3) Heat Capacity (T4) Temperature Dependence of the Enthalpy of Reaction (T5) Entropy (T6) Entropy Changes as a Function of Temperature (T7) The Third Law of Thermodynamics (T8) Activities Second Semester Gibbs Energy and Helmholtz Energy (T9) Gibbs Energy as a Function of Temperature and Pressure (T10) Equilibrium (T11) Temperature Dependence of the Equilibrium Constant (T12) Temperature and Pressure Dependence of Phase Equilibria for Pure Phases (T13) Vapor Phase and One Component Phase Diagrams (T14) Partial Molar Volumes (T17) Enzyme Kinetics (K6) Strengths • students enjoyed POGIL, working together • students believed they learned more and better • more difficult concepts more easily mastered • conversation and laughter • very good class discussions Areas for Improvement • much more time-consuming • stronger students dominated difficult material • students sometimes missed key points • how to study for exams? • small class size was a problem Insights • enjoyment of physical chemistry • reduced fear of the course? • exam scores, grades Chen with ACS officers Conclusion Strengths • students like POGIL, enjoy class more • greater comfort level with chemical concepts & language • difficult topics are less intimidating • weaker students may do better • offers structured way to provide another class format Areas for Improvement • emphasize process & roles • requires more time • Facilitation Insights • student performance • student attitudes • interactivity • communication skills Plans for 2006-2007 Jensen will use POGIL again in General Chemistry I Would like to use POGIL in analytical chemistry courses Chen will use POGIL again in General Chemistry II, Organic Chemistry I and Physical Chemistry • explore ways to answer without frustrating students • select activities carefully • stay on schedule • improve Facilitation Acknowledgements Aquinas College Faculty Development Committee Aquinas College Department of Chemistry Students in our 2005-2006 courses POGIL Project personnel
