BSCI 207 Principles of Biology III: Organismal Biology

1) To help BSCI students master the fundamental principles of organismal biology focusing on the function, structure, and diversity of all organisms.2) To help BSCI students develop student-centered and group-enabled skills for greater success in UM courses and future careers.

Academic activities vs. job skills

First discussion: Identify the activities to which you devoted the most time in previous biology classes.

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

BSCI 207: Organismal Biology

Universal physical and chemical lawsCommon genomic heritageDiverse structure-functional relationships

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."

On the Origin of Species, 1st Edition, 1859F. Fig. 23.1

Is there a major difference between how students and professional biologists (doctors, teachers, researchers, etc.) approach biology learning?

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

Clicker question: I believe that I will get better grades by studying on my own, as opposed to working in small groups. 1. Strongly disagree

Pedagogical reform

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

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
