OBJECTIVES
Teaching Goals
The very first day of class often feels like a first date, with both students and instructors sizing up
each other and the course in general. Instructors need to put their best foot forward but often feel the
need to cover only important—but dull—administrative details. Try to remember that this is your
chance to sell the course and yourself. Students are deciding whether to take a course by judging
workload as well as content, so be sure to include the following:
• Something about yourself: Explain your personal teaching goals and interest in biology.
• Syllabus: As hard as you try, you will never be able to cover all the important administrative
information in a single lecture, nor can you cover every exception and possibility. Also, students
are unlikely to remember most of the comments an instructor makes during this first lecture
anyway. That’s where a good syllabus can help you. A syllabus serves as a contract, setting
forth what the course is about, what students will be expected to do and when, and how much
each assignment contributes to their grade. With a good syllabus, you can cover only what
students must know on the first day of class; then, as the course continues, they can refer to the
syllabus for other information. Be sure to fill out the following checklist for your course syllabus:
– Instructor information: name, title, office location, office hours, telephone, e-mail, how
you prefer to be reached
– Course: number, section, meeting times, and location
– Course description: general objectives and topics to be covered on specific dates
– Course objectives: the most important accomplishments students will attain in your course
– Required purchases: texts and supplies
– Due dates: (place and time) for major assignments and exams
– Grading: relative weight of each assignment, general standards, policy about Incomplete,
Pass/Fail, or Withdrawal
– Course policies: attendance, academic dishonesty, late assignments

,2 Instructor Guide
You will avoid a lot of headaches by spelling out policies in writing at the beginning of the
course and making it known that you will hold students to these policies.
• Salesmanship: Do not be afraid to sell the course a little. Cover the highlights. What are some
practical things that students will be able to do after they complete the course? Why should they
be interested in the course content? Use whatever means you can to impress upon students the
value of studying biology: show a series of beautiful photographs, or clips from recent movies
or magazines.
Student Goals
By the end of this lecture series, students should understand these concepts:
• Why it is important to acquire a basic knowledge of biology
• How science is actually done: theories, hypothesis, and applying the scientific method
• The definition of life and hierarchy of living things
• The role of evolution as the chief unifying principle of biology
SCIENCE AND SOCIETY
An understanding of science is no longer something that students can get along without. Biology, in
particular, now pervades many areas of our lives, from diet, the ability to reproduce, and decisions
about health choices to societal responsibilities as taxpayers or jurors. Chapter 1 details just a few
news stories relating this importance. Scientific breakthroughs will need to be communicated, and
students will need the skills necessary to understand their significance. In addition, all students,
future scientists and nonscientists alike, will face important decisions in the future that may hinge on
their understanding of the basic principles of living organisms, as well as their ability to think
critically. Whether they go on to be involved in government, the media, or other nonscience fields
that shape policy or public opinion, or simply make their choices in the voting booth, they all will be
called on to make decisions on such fundamental issues as global warming, population pressures,
pesticide use, introduction of genetically engineered foods, or the allocation of research dollars. This
is our chance to make sure they are well-informed citizens.

INTERACTIVE ACTIVITIES
Interactive Activity 1.1—The Impact of Science on the Everyday World
Introduction: The purpose of this activity is to bring to the students’ minds some of the positive
impacts of science on their lives, many of which they may take for granted. Students will recall and
document scientific discoveries or advances that benefit their lives. This is a good strategy to help
them see why learning about science is valuable and to spur their interest.
