Academic experiences vs. job skills
First discussion: Identify the activities to which you devoted the most time in previous biology classes.
Second discussion: Identify the job skills that will be most important for professional biologists in 21st century.

BSCI Program Is Transforming Itself• Focus on BSCI 207 as the gateway course into BSCI major• Switch the emphasis from acquiring isolated facts toward
developing conceptual models for organizing knowledge• Utilize active-engagement approaches to encourage student-
directed and group-enabled learning and problem solving (Friday AM @ 9 (section 0101) or 10 (section 0102) in PLS 1140)• Do diagnostic assessments of student learning and attitudes• Use education specialists to study the teaching of BSCI faculty,
and how students learn from those faculty

Charles Darwin’s concluding sentence“There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."

Content Reform in Biology Classes
New pedagogy - focus on mastering concepts/principles/big ideas, and using facts to define, explain, evaluate, and apply
those conceptsOne 207 goal – to help you learn how to build conceptual models

Overwhelming evidence in favor of small groups(for everyody else?!)
Treisman (1992) College Mathematics Journal 23:362-372Observations: at-risk students tend to study alone excellent students tend to study in groupsResults: the differences disappear if at-risk students study in groups. Why?
Wood (2007) Life Sciences Education 7:263-264Procedure – 1) Ask a clicker question, and sort out the students with the
right answer from those with the wrong answers; and2) Pair the wrong students to discuss the subject, and then ask a similar
question. Over 75% of the students in the wrong pairs got the second question right. Why?

New pedagogy – to encourage active group-enabled learning, as opposed to passive individual learningAnother 207 goal - to improve your group learning skills

Basic structure of 207 GAE(Group Active Engagement)
Conceptual models in subsequent weeks – e.g., phylogenetic trees, endosymbiosis, random walk simulations, transport models, etc.
Homework – outside-class group discussion (Monday-Thursday), and individual writing (after that discussion and due Friday 2/4)
Developing skills
Conceptual models for major principles
In-class group activities
Outside – class group activities
Group dynamics
Biological energy flow; thermodynamic laws
Flow diagramming;brainstorming
Apply model to solve problems

New pedagogy #3– perform formative (on-going) assessments of the effectiveness of the teachers and class activities207 response - Bio education specialists (Kristi Hall and Jessica Watkins) – use class surveys and student interviews to evaluate class

I do not announce to my colleagues that I have memorized allthe facts in a particular chapter of Freeman. We don’t practice memorizing facts.
We do something different, and so do you. Just not yet in biology.
I want you to spend the next minute or so writing the first sentence of an essay describing the University of Maryland
