Tips for success in Biol 205
by Joann Otto & Carol Trent
In Biol 205, we examine a variety of processes that occur in cells. Often we will be discussing a
topic over several days. Some students lose sight of the ‘forest for the trees’; in other words,
they become lost in the details and how they relate to the big picture. Further, we cover a great
deal of material, and students who wait until the last minute to study are overwhelmed. There are
several strategies to learn the material in the course efficiently. These are outlined below:
1. Read the text to get the major ideas and terms related
to a topic BEFORE lecture. The text contains far more material than
can possibly be discussed in lecture so do not worry about the details. The figures in the text
illustrate the major ideas and should be very useful. By doing this reading prior to class, you will
come to lecture prepared to listen and learn and to take accurate notes. At a minimum, read the
bold headings of sections and the definitions of words in bold, study the figures and legends, and
read the section or chapter summary prior to coming to class.
2. Soon after lecture, check your notes to be sure
they are clear to you. Then, knowing the parts of
the reading that were emphasized in the lecture,
reread the text more thoroughly and focus on the
parts that were emphasized in lecture. You can use the text to
clarify your notes and cross reference figures that help you understand lecture material. It is very
useful to write a paragraph summarizing the main points of the lecture or to make a list of the
main points. If you cannot list only 4-5 main points, you probably do not understand the
material (the forest vs. the trees problem).
3. Be an efficient learner. In the few minutes
before class starts, review your notes from the
previous lecture. Often, our discussion of a topic will span several lectures and by
reviewing the previous lecture, you will get your brain ready for the new one.
4. Form study groups. There are different strategies to make a study group
successful but all require that all the participants have studied the material prior to meeting.
Groups may want individuals basically to teach the others how a process works; teaching is the
best way to learn something. Alternatively, participants can quiz each on the study questions
10
provided by the instructor. Taking the questions as a mock exam (and grading each other) is an
excellent way to learn the material.
5. Take advantage of office hours. I am very
willing to help you.
6. When taking an exam, carefully read the
questions. The, reread each question to be certain
that you understand it.
All of the above might seem to require a
great deal of time. However, if you keep up
as the quarter goes along, you will not be
panic stricken the day before an exam.
Further, keep in mind that, at the college
level, you should be spending 3-4 hours
studying for each hour you spend in lecture.
As with any endeavor, you will get out of
this class what you put into it.

Becoming an Effective Learner for Biol 205
Adapted from A Miniature Guide for Students on How to Study and Learn a
Discipline using Critical Thinking Concepts and Tools by Richard Paul and Linda
Elder
Effective Reading
1) Become an active reader. First read your textbook structurally.
Examine the table of contents for a chapter and summarize in your
own words the main points of the chapter. Then use close reading
to learn about the specific ideas which supporting the main points.
After each paragraph, summarize the essential idea behind the
paragraph using key terms. Also be sure to examine each figure or
diagram carefully and summarize their important points. Be sure
to read the figure legend.
2) Learn to associate particular people with scientific discoveries –
this helps to put scientific discoveries in a context. Summarize the
importance of an investigator’s research and explain why it is
relevant for this area of biology.
3) Consider that this class is training you to think like a biologist,
and more specifically, like a molecular and cell biologist or
biochemist or geneticist. You should pay close attention to key
experiments that help define these sub-disciplines. Look for
interconnections that unify these sub-disciplines.
Effective Listening
1) Read your textbook in advance of lecture. Oftentimes, lectures
will use the textbook readings as background and will not make
sense if you have not kept up with the assigned readings.
2) Test yourself before class by summarizing the main points of the
previous class. If you cannot summarize main points, you have
not learned them.
3) During class, actively listen. Ask questions to fill in missing
pieces. Make interconnections with previous lectures or courses.
Your lecturer loves questions as.
12
4) Note-taking is important tool for becoming an active learner. So,
detailed lecture notes (except for the figures not found in textbook)
will typically not be posted on the web.
5) Test yourself soon after class by summarizing the main points of
the class. Identify the key questions in the lecture.
Effective Learning
1) Learn how to identify what you do not understand, and, if
possible, why you do not understand it.
2) Test your understanding of biology by explaining what you have
learned to someone who is not taking Biol 205 – mom, dad and
sibs are fair targets.
3) Always ask for clarification – by email, or questions in class or in
office hours.
4) Understand the philosophy of testing. In general, our philosophy
in testing for Biol 205 is to include on tests a mixture of factual
recall, experimental analysis and applications of concepts to new
situations. With this approach, students who try to memorize the
textbook do very poorly. One way to prepare for the more
challenging tests is to think about what would happen if one
component involved in a process is not working.

During the past few years, molecular geneticists
and cell biologists have announced
(usually with great fanfare and attention
from the popular press) specific
accomplishments with respect to the study
of biology
Biology in the Popular Press
What topics appear regularly?
What topics have interested you?
14
Consider the following questions:
1. How does a living system differ from one
that is not alive?
In other words:
• What essential characteristics are found in
all living systems yet known?
• What does a cell need to do to be alive?
2.What is the program or information center
that directs the living system?
3.How ancient are the lineages of various
types of organisms?
