and Applications of Organic and Biological Chemistry
My POGIL Journey

2004 BCCE – POGIL Workshops

Year 2004-2005 - Added some POGIL to
Organic/Biochemistry Course


Exercises mostly for the organic portion of the course
Summer, 2005 – POGIL Workshop on Writing
Materials

Year 2005-2006 - No lecture – all POGIL in
Organic/Biochemistry Course

Added POGIL exercises for all biochemistry

POGIL method adopted due to challenge of nonchemistry students

One hour of lecture was given to POGIL in Year
2004-2005
Last hour of lecture was given to POGIL in Year
2005-2006


Tests and quizzes - same format and content

POGIL materials were NOT graded

Fall to fall for 2004 and 2005
Spring to spring for 2005 and 2006
Also for the whole year – fall and spring data
combined
Is there any significant difference in learning?

“I liked this method of learning.”
“This helped me to understand the material.”
“They helped me apply what we were
learning.”
“I honestly think this is the best way for me to
understand material.”
“I could ask questions if I didn’t understand
and classmates helped.”
