Assessment report for BL A 106 (Principles of Biology II) [prepared May
A total of 158 undergraduates completed BL A106 Fall 2002
There were 3 in-class tests of 35 points, and the statistics are as follows:
Test 1- Mean-20.73, Standard deviation-5.83, High-35, Low-8
Test 2- Mean-22.87, Standard deviation-5.38, High-35, Low-10
Test 3- Mean-22.52, Standard deviation-6.06, High-34, Low-5
Also there was a final of 50 points, and the statistics are as follows
Final- Mean-34.72, Standard deviation-7.38, High-49, Low-12
The grim reality is that pupils the lowest performance averaged about chance.
On the other side of the coin, the performance of poor students is a metric
to evaluate the performance of the top students. The top scores are outstanding
considering how clearly challenging the informational content of the course
was. It is clear that this assessment is as much of the course and its material
as it is of the top-notch students.
At the present time, the course (exams and answers included) can be found
Below, I reproduce the assessment plan:
Outcomes Assessment Plan for Principles of Biology II (BL A106)
Dr. William Stark
Prepared January, 2002
This course is intended for freshmen. By this, the second semester, non-science
majors fulfilling their arts and sciences science requirement are no longer
taking Principles of Biology. This leaves mostly students who are or presently
intend to be biology majors; also there are pre-health professionals majoring
in other departments.
Description from the Saint Louis University Undergraduate Catalogue:
BL-A106 Principles of Biology II (4)
Lecture three hours per week, laboratory three hours per week. A continuation
of BL-A104. Course emphasizes plant and animal development, ecology, behavior,
structure and function of organ systems, and phylogeny.
A student completing BL 106 lecture should be well educated in the process
of scientific discovery in biology, in the basic principles of biology relating
to diversity of organisms, structure and function, animal behavior and ecology.
Prospective Biology majors attaining these goals will be prepared to continue
in subsequent Biology courses. Students pursuing other majors will have
acquired a broad foundation in Biological Science.
These objectives are the same for my section (-01) of BL A106 as well as
the other section (-02). In compliance with a requirement from the Provost's
office, as communicated to the freshman teachers on October 1, 2001 by Biology's
assessment committee, these objectives are made available to students on
the syllabus (in my case by being hyperlinked to the syllabus on my course
Students are expected to learn a considerable amount of information in the
field of biology provided by:
(a) A modern and pedagogically advanced text.
(b) A web page providing lecture outlines and past examinations (http://starklab.slu.edu/Bio2000/Bio1062000Syllabus.htm).
(c) Lectures utilizing the web outline and informational diagrams.
Special features of the lecture:
(a) Fundamental points are repeated in every context to which they apply,
and it is considered that redundancy is very good in pedagogy.
(b) Whenever possible, a topic is developed with something the students
should already know as the starting point.
(c) The previous point notwithstanding, enough background is presented in
an attempt to make every point understandable by the intelligent but uninformed.
(d) The syllabus touches on every chapter in a somewhat encyclopaedic text.
(e) Stories are presented that integrtate material from different chapters.
(f) Reference is made to when a certain point was covered before or will
be covered later (hyperlinks).
The scope of this information is intended to prepare students with the biology
background that would be essential for
(a) being a student educated in science.
(b) all higher level biology courses.
Three in-class hourly exams and a final exam are administered and graded.
Students keep the question booklets as part of their learning experience,
and answers are posted on the internet after the exam. Special features
of the exams are as follows:
(a) All questions are completely objective and are multiple choice.
(b) Exams are short enough that running out of time is not a consideration.
(c) In many instances, these questions are specifically designed to apply
and integrate the information.
(d) The tests are very difficult, as judged by how the class performs.
For the sake of record keeping, answer sheets are retained by the professor.
On September 21, 2000, "each faculty member" was charged to "develop
an outcome assessment tool." I have decided that the best assessment
centers around traditional tests. I devote a considerable amount of time
(about 100 hours per semester) writing tests that will be fair, discriminating
and useful as a learning experience. While the information gathered is extremely
useful, it cannot be used to compare background of students with any national
It is quite useful to have the scores be widely distributed so that grades
represent the real differences in student abilities. Grades in science courses
are essential in determining coveted access into medical and other health
professional schools. There are many students for whom science is not their
forte. It is crucial at the introductory level in the sciences to give these
students the information they need to make intelligent choices about their
majors before they invest too much effort and get in over their heads at
the upper division classes.
To serve the function of grading students, the test must be challenging
enough to distinguish different performance levels. Only the performance
of the best students on the test can be a meaningful way to assess whether
the course achieved what was claimed above, i.e. presentation of a "considerable
amount of information in the field of biology." If the best students
do well, it can also be concluded that the material was presented in a way
where (s)he could learn it. Importantly, it is the poor performance of some
students that offers the necessary control for this analysis -- proof that
there was a lot to learn.
In a memo dated 9/12/01, The Biology Department's newly formed assessment
committee stated for the first time that assessments should lead us to develop
"a statement indicating how the information they have gathered over
the past year assisted them in improving teaching skills and/or course content."
If (perish the thought) the main goal were to show uniformly high performance
among students with widely differing capabilities, then I could achieve
that goal by either covering less information or writing easier tests. In
either case, grade inflation would be a necessary outcome, and that is unacceptable.
I have devoted a vast fraction of my entire career as a university scholar
in teaching for over 30 years. Much of that effort is focussed on "improving
teaching skills and/or course content" by further mastering and organizing
the material and making its presentation more accessible. These improvements
are a lifelong and continuing process and they will continue irrespective
of a statement of the analysis of this course's assessment.
In compliance with a requirement from the Provost's office, relayed to
the Biology faculty at a faculty meeting on January 14, 2002 by the chair
and the assessment committee, I will hyperlink a brief statement about assessment
to the syllabus (see above, Assessment section).
