Student Learning Assessment
Biological and Chemical
Sciences Major
Fall 2007
A Wells
education enables students to:
The Major in Biological and
Chemical Sciences
Mission of the Major
The major in
biological and chemical sciences provides students the opportunity and the
guidance to build for themselves a foundation in the fundamental areas of
biology, the study of life, and chemistry, the study of matter, with particular
emphasis on the areas integrating biology and chemistry. Students engage in
active learning as they apply the scientific method towards understanding the
natural world. As such, students think critically and creatively in evaluating
data as well as issues related to biology and chemistry in society, including
ethical conflicts surrounding particular scientific theories, technologies, or
applications, and are trained to write and speak effectively about science and
scientific issues. The BCS major helps students to understand diversity in the
practice of science, through highlighting the important contributions of women
and minorities and recognizing cultural bias and societal perspectives.
Students are prepared for a variety of careers as well as advanced study in
graduate school or any of the health professions

Means of Assessment of
Outcomes
Student
artifacts will be collected throughout the 2007-2008 academic year by the
faculty member teaching the targeted courses. Each faculty member will evaluate
if the students learned what was expected. Percentages of how well the student
answered/completed the activity will be calculated, and students will be
considered proficient if 70% of the students demonstrated a passing grade on
the assessed activity.
How Assessment Data will
be utilized
The Biological and
Chemical Sciences major will meet yearly – at the start of the fall semester –
to discuss the assessment of the previous academic year and to create a plan
for the current year. At this meeting we will discuss if our students met our
assessment goals, and if not, how to improve student learning for the future.
At the conclusion of this meeting we will create our assessment plan for the
current year.
Plan for the 2007-2008 academic year: BCS will collect student work for the
targeted courses, and each instructor will evaluate if our students are
demonstrating learning. In this trial run of assessment, we are hoping to
streamline how we actually do assessment of student learning. Next August we
will meet to discuss our collected artifacts and make a plan for the future –
what worked, and what didn’t?
Specific Course
Objectives and Assessment Measures for Required Courses

Biology Courses
BIOL 151L:
Principles of Biology I – The Biology of Cells
1. For each
student to master enough of the basic information about the biology of the cell
to build a "big picture" about how cells work. (1)
See, for example, answer keys to Chem
Quiz (Fall, 2005), Exam I (October 30, 2005), Exam II (October 28, 2005), Exam
III (November 21-22, 2005), Final Exam (December 15, 2005 – Part I).
2. For each student to experience the process of
science – to ask a question, to design and conduct experiments, to analyze the
data, to communicate the results both orally and in writing (2, 3a, 3c, 3e)
See, for example, the instructions and
grading keys for two major lab reports:
1) Oral and Written reports
on “Independent Investigations on the Enzyme
Tyrosinase”
and
2) a) Short oral and written
reports on “The Alcohol Dehydrogenase Gene in
Drosophila”
– see instructions on page 4 of the lab (“Lab 8”)
description
b) Written report – “Drosophila Lab Report”
– on the genetic analysis of a
mutant
3. For each student to develop critical
thinking and cooperative learning skills. (3b)
For “critical thinking,” see
for example Genetics Problem Set – problems
and answer key; also, see example of “clicker” thought
question during
class time, and answer sheet
from student responses
For “cooperative learning
skills” see instructions for Oral report on
“Independent Investigations
on the Enzyme Tyrosinase”; see instructions for
Oral report on “The Alcohol
Dehydrogenase Gene in Drosophila” – page 4
4.
For each student to see the applications of the biology of the cell to
the world around us, and to consider the ethical implications of related
technology (3f, 5)
See, for example,
description of Lab #1, Resource Packet, and Hand-In Sheet
– “Embryonic Stem Cells,
Cloning, and the Law” – an ethical
analysis of a
bill passed by the US
Congress, but vetoed by President Bush, on research
on human embryonic stem
cells
See, for example, the
description of the student debates on two case studies –
- whether or not
“Intelligent Design” should be taught in the public schools
as part of science classes,
and whether or not transgenic plants should be
planted on the outskirts of
a small town
5.
For each student to sharpen the skills of learning how to learn, and to
continue the process of life-long learning in biology (1, 2, 3b)
See, for example,
description of Lab #1, Resource Packet, and Hand-In Sheet – “Embryonic Stem
Cells, Cloning, and the Law” – where students
are directed to talk about the issue in this lab, to make diagrams to explain
the techniques involved, to present the techniques to the class, and to write
down their decisions whether to vote yes or no on the bill – all different ways
of working on the information, with the hope that several of these (but not
necessarily the same ones) will be particularly effective for every student)

CHEM 213L - Organic Chemistry I
Chemistry
213L is the first semester of a two-semester lecture and laboratory class. The lecture portion of the class teaches
students the fundamental concepts in organic chemistry. In the laboratory
section students practice important techniques used in the organic chemistry
lab. A pre-requisite for the course is
general chemistry (Chem108L), and students in the class are typically in their
sophomore year. This is a core class in
the BCS major and is taken by students in all three major concentrations.
1. Recognize how the structure of carbon based
molecules can aid in predicting reactivity, including acid/base and
nucleophile/electrophile chemistry.(1,3b,3c)
-
These are assessed on the in-class exams and
quizzes. I have given a specific example
from one of the exams. Questions 5 and 6
test the students’ knowledge of acids/bases as well as nucleophiles.
-
Relevant artifacts:
o Chem213L
final exam - Questions 5 and 6
o Chem213L
in-class exam #3 - Questions 8, 9, and 10
2. Evaluate how organic chemistry plays a role
in our lives and how it is all around us. (1,2,3c,3f,4,5)
-
I typically use case-studies and in-class
exercises that the students work on in groups.
The exercises are not typically collected, but the worksheets the
students are given illustrate how this objective is met.
-
Relevant artifacts:
o Rubbers
and Raincoats in-class exercise*
o A
Case-study: Thalidomide: The pros and cons*
3. Become familiar with the techniques used by
an organic chemist in the lab and learn how to keep a good lab notebook.
(1,2,3a,3d,3f)
-
Keeping a good lab notebook is essential for
scientists and the students’ ability to write in one is assessed by grading
them. Each laboratory exercise teaches
the students a new technique in organic chemistry.
-
Relevant artifacts:
o Chem213L
Lab Notebook sheet and grading rubric
o Week 1
– Introduction to Techniques in the Organic Chemistry Lab (technique: melting

(techniques: extraction, crystallization) and example lab notebook*
o Week 4
and 5 – Extraction of Caffeine from Tea (techniques: extraction, sublimation,
thin layer chromatography) and example lab notebook*
4. Identify trends in mechanisms and reactivity
to reduce the amount of memorization needed (1,2,3b).
-
There are a number of reactions that must be
learned in organic chemistry. To aid the
students in recognizing trends, they must complete a reaction notebook. This exercise highlights important trends in
reactivity as well as reaction mechanisms.
-
Relevant artifacts:
o List of
topics/information needed in your notebook
o Chem213L
Student Reaction Notebook
5. Work together to solve a problem that has
not been previously encountered and present the information to the class.
(3a,3b,3c,3e)
-
In their final lab project, students are
given a new reaction that they have not previously seen in lab. They are to use the skills developed
previously in lab as well as the knowledge gained in class to work through the
problem. The information must be presented
to the class.
-
Relevant artifacts included:
o Chem213L
Final Lab Project handout
o Chem213L

3. Become familiar with the techniques used by
an organic chemist in the lab and learn how to keep a good lab notebook.
(1,2,3a,3d,3f)
-
In order to illustrate some of the important
spectrophotometric techniques used in organic chemistry, I have the supplement
my lecture with in-class exercises that are completed as the lecture
progresses.
-
Relevant artifacts:
o Chem214L
– 1H-NMR worksheets*
4. Identify trends in mechanisms and reactivity
to reduce the amount of memorization needed (1,2,3b).
-
There are a number of reactions that must be
learned in organic chemistry. To aid the
students in recognizing trends, they must complete a reaction notebook. This exercise highlights important trends in
reactivity as well as reaction mechanisms.

5. Work together to solve a problem that has
not been previously encountered and present the information to the class.
(3a,3b,3c,3e)
-
In their final lab project, students are
given a new reaction that they have not previously seen in lab. They are to use the skills developed
previously in lab as well as the knowledge gained in class to work through the
problem. The information must be
presented to the class. They must also
identify a viable alternative synthesis to the one they will be carrying out
using the primary scientific literature.

Relevant artifacts included:
o Chem214L
Final Project - Presentation handout and grading rubric
o Chem214L
Student rubric and presentation (3-Step Preparation of Polystyrene from
Ethylbenzene)
6. Work through a series of organic
transformations in the lab and in class (a multi-step reaction sequence).
(1,2,3a,3c,3d)
-
These are assessed both in the lab and
in-class on the exams, quizzes and in-class exercises.
-
Relevant artifacts:
o Chem214L
Final exam - Question 4
o 2-Step

7. Apply knowledge of reactions learned in
class to laboratory exercises. (1, 3a-c)
-
This is actually done in a number of the
labs, but I will give a specific example of how the NMR lectures and worksheets
are integrated into the labs.

Relevant artifacts:
o Addition
of I2 to 4-pentenoic acid – with a twist! and student lab notebook*
8. Identify synthetic routes to complex
molecules using reactions encountered in class. (1,2)
-
Assessing the students’ ability to do this
is done using exams, quizzes and in-class exercises. A few examples are given below:
o Exam
Question 10
o Chapter
15 in-class exercise – Diels-Alder Reactions
o Chapter
10 in-class exercise – Retrosynthesis
o Electrophilic
Aromatic Substitution in-class exercise
9. Choose a problem to study in the lab and
design methods using the primary scientific literature to solve the problem
utilizing the scientific method. (1,2,3a-f)
-
The students are first given a worksheet
describing how to examine the scientific literature. Their ability to search and use the primary
literature is done through the writing of a proposal, where they must use and
properly cite references.
