Just Do It: Perspectives of First-Time POGIL Implementers Elizabeth Jensen & Li-Heng Chen Department of Chemistry Aquinas College Grand Rapids, Michigan Our Home: Albertus Magnus Hall of Science
Aquinas College PUI, 4-year private Catholic founded 1886 by Dominican Sisters of Grand Rapids approx students (400 nontraditional; 400 graduate) Chemistry Department 3 faculty, 1 lab manager 3-5 majors, ~10 minors per year traditional program - 1 year general chemistry - 1 year organic chemistry - 1 year physical chemistry - 1 sem. quantitative analysis - 2 sem. chemistry electives - independent research project Jensen with student in lab
Our Backgrounds Jensen 3 years at AQ analytical and inorganic courses attended several POGIL workshops over two years Chen 20+ years at AQ organic and physical courses attended one POGIL workshop What we liked about POGIL constructivist/ learning cycle peer working groups practice discussing concepts/language process of problem solving well-defined team structure alternative to lecturing Chen teaching physical chemistry
Taking the Plunge Fall 2005 General Chemistry I (Jensen) Organic Chemistry I (Chen) Physical Chemistry I (Chen) Spring 2006 General Chemistry II (Chen) Physical Chemistry II (Chen)
Team Organization assigned teams using exam scores team reports time allowed Manager Recorder/Reflector Presenter 3 students Manager Recorder Presenter Reflector 4 students Presenter Responsible for: presenting oral and written reports. representing the team to the class. participating in team activities.

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 2 nd semester 6 vs drops n = 41 n = 140

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 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) First Semester

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 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 Strengths Areas for Improvement emphasize process & roles requires more time Facilitation Insights student performance student attitudes interactivity communication skills
Plans for 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
