The Chemistry department uses capstone projects in three primary courses: Chemistry 110L, 141 and 164. The department has several undergraduate degree programs and not all students take the same sequence of upper division courses; these three courses capture all majors. In addition, capstone-like projects are also introduced into Chemistry 125 and 133 to provide students opportunities to experience the requirements and demands of this assessment.
A capstone experience may vary depending on the class. However, the essential features are the same: (1) Agreement between instructor and student on a small laboratory project; (2) a literature survey; (3) a student attempts to complete the experimental project; and (4) a student presents the results in public via a poster presentation involving the student standing with the poster and answering questions [a paper and oral report are often required].
The faculty met on February 1, 2001, to review the results of capstone projects and particularly the poster presentations. The following form was used by faculty to develop their individual assessment of the overall results of poster project presentations. In the meeting of faculty a consensus was reached regarding each statement. That consensus is indicated in red type with each statement. Additional issues were discussed and these follow the questionnaire.
The purpose of the assessment is to obtain a "picture" of the skills and abilities of students as shown by their poster presentations. This form is used to provide an overall assessment of the poster projects with respect to the level of the classes involved in the presentations.
For the level of the classes and based on the presentation in the poster, please assess the following:

Issues and Conclusions developed at February 2, 2001 meeting:
- It is the consensus of the faculty that the capstone projects
and poster presentations are a very effective assessment tool for
demonstrating that students can initiate a small chemistry-based
project, research the literature, do the experimental procedures
and then present the results in a poster format. Several faculty
reported that they have had students tell them that the capstone
project helped them become employed. In particular, students are
able to effectively answer questions in interviews dealing with
preparing reports in a scientific format and orally giving a presentation
or defending results.
- Most poster presentations are effectively organized, the project
is carefully structured and the presentation shows how the problem
was solved. In some cases students did not carefully support their
conclusions or analyze their results.
- The posters effectively used graphic designs and other visual
aids. Many students developed sophisticated computer presentations
that were placed on the poster or did very interesting art work.
Molecular modeling results often showed interesting molecular structures.
- In most cases writing was satisfactory or better. Students who
do not have English as their primary language have more difficulty.
They are not as comfortable expressing themselves in English and
they are not sufficiently trained in scientific format. Faculty
work with students during the semester but it is a challenge to
change skills when English is weak for a student. Students may be
referred to the English tutoring center when serious problems exist.
- The department stresses the use of modern instrumentation when
solving chemical problems. This means that students are trained
to use a variety of instruments. This clearly shows in their poster
presentations. Most students will use one or more instruments to
develop data for their project.
- Most students are able to collect a reasonable amount of data
that is useful in solving their problem. There are some students
who have difficulty developing good conclusions from experimental
data, often resulting from the student initiating the project too
late. Faculty are focusing on possible procedures to ensure students
start projects earlier and stay on task.
- There is a problem with differences in training of students
in laboratory skills if they are transfer students. Some students
arrive well-trained in modern chemical laboratory and instrumental
techniques; at other community colleges the training is less satisfactory.
This means some students initially struggle when they first enter
an upper division laboratory class. Faculty may consider a one or
two unit laboratory class that transfer students with weak laboratory
skills could take to improve them. Issues re potential number of
interested students and availability of faculty dollars to support
such a course need to be addressed.
- Capstone projects require a high degree of sophistication in
laboratory skills at the undergraduate level. Further discussion
is needed to assess whether the level of expectations for capstone
projects is too high.
- Students obtain hands-on experience with a wide variety of instrumentation,
for example: nmr; gc-ms; uv-vis; hplc; fluorescence spectroscopy;
electrophoresis; and voltammetry. This opportunity is one of the
unique differences between our chemistry department and those at
major research institutions.
- Faculty are considering whether students should work in teams. In Chemistry 164 the instructor is now using this approach with good success in terms of students successfully completing capstone projects. A concern about the use of student teams is whether each student develops independent laboratory skills; faculty need to consider this possibility in future design of capstone projects.
