Assessment Report
CHEM
5710 – Spring 2007
Instructor: Joan M. Hevel
Course Description:
General Biochemistry II is the second of a two semester course
sequence in Biochemistry. The intent of this sequence is to provide
a thorough and comprehensive survey of biochemistry for science majors
(undergraduates and graduates). Chemistry 5710 will focuses on
anabolism, signaling and information pathways.
Enrollment:
34
Assessment method: On the first
day of class students were given a gain score quiz consisting of 11
questions that cover the learning objectives. The quiz was graded
but not given back to the students. Three lectures before
the end of the semester the students were given the same quiz.
Students were encouraged to take the quiz seriously by allowing the
graded gain score quiz to take the place of a regular WebCT-based quiz
in which they may have received a low score.
Learning Objectives
The following broad learning objectives
were identified in the course syllabus:
1.
Describe the basic biochemical principles of photosynthesis:
general features, light absorption and light-driven electron flow and
ATP synthesis
2. Describe the biochemical basis
for carbohydrate, lipid, nucleic acid, and protein synthesis: cellular
location, functions of enzymes, regulation, and function of products
3. Explain the use of DNA technologies
in the research laboratory, the clinic and in industry
4. Develop a comprehensive
view of how higher organisms receive and respond to external stimuli
at the biochemical level
5. Describe how mammalian
metabolism is integrated as demonstrated by hormonal regulation
6. Describe the structure
and topology of chromosomes and genes and how they are packaged and
how this relates to gene expression
7. Explain how the expression
of genetic information is regulated
Additionally, as stated in the syllabus,
exams may have some “regurgitation elements” but the bulk of the
questions are meant to test the student’s ability to apply the
knowledge.
Outcomes
Gain Score Quizzing:
The average grade on the initial quiz was 7.7 out of 100. Most students appeared to already have superficial knowledge of DNA packaging, DNA-related mechanisms including repair and replication, and were aware of introns and exons.
The average grade on the final
quiz was a 66 out of 100 with the high being an 89.
Correct answers for all learning objectives increased.
Performance by students on semester
exams
Semester Exams:
| Exam | 1 | 2 | 3 |
| Mean | 71.8 | 75.6 | 80.8 |
Since many questions on the exams require the application
of knowledge instead of the memorization of facts, students
often do not do well on the first exam. This year was no
different. However,
as the table to the right shows, exam means steadily increased over
the semester. This year an intensive graded homework assignment
was given along with several assignments that required the students
to “practice” using their learned information.
Student Evaluation:
The overall quality of the course was
evaluated at a 5.2/6 compared to the departmental average of 4.3.
Instructor effectiveness was rated at 5.4/6. Suggestions to improve
the course are to not extend the class lecture beyond the 50-minute
mark, to alter the weekly Web CT quizzes, and possibly to add another
homework assignment. Students were overwhelmingly pleased
with the prepared lecture slides, style, enthusiasm and presentation.
They liked how information was tied to real-world examples and many
said the DNA technologies homework assignment (although a lot of work)
was very helpful.
Assessment
Overall the students showed improved command of the discipline by both gain score quizzing and increased exam means throughout the semester. In response to students concerns last year, more examples of applying the information were given. This included the added homework assignment covering DNA technologies. This assignment appeared to be very helpful to students in terms of being able to apply the information. A second graded homework assignment will be added next year that will represent the entire semester. The questions in the homework assignment will require the students to use information from different chapters, pull it all together and formulate an answer. This should also be a strategic way to study for the final.
Concerns: Although being able to apply the information is a top priority, finding a way to help the students retain the salient features of this course is also important. Some suggestions include the identification of a booklet of condensed information, “Cliff Note” style that can be used throughout the semester.
