Assessment Outcomes Data Report
CHEM 1210
– FALL 2006
Instructor: Joan M. Hevel
Course Description:
Principles of Chemistry I, First of a two-semester sequence covering
fundamentals of chemistry. Designed for science and engineering
students.
Enrollment: 208
Assessment method:
Embedded questions were presented in the Final exam that pertain to
11 different learning objectives. Some questions required two
or more learning objectives to be mastered in order to answer the question
correctly.
Outcomes Data: The target areas for learning are listed below:
Embedded Question Targets Fall 1210 2006
A. Mathematical manipulations-interchanging units with conversion factors
B. Memorization of nomenclature rules and the ability to apply them.
C. Correct identification of molecules as ions, atoms, elements, compounds, acids, bases, electrolytes, etc. Write a correct empirical and molecular formula.
D. Balancing and using a chemical equation to answer quantitative questions about a particular reaction (e.g., use of coefficients, % yield, limiting reagents, etc.)
E. Knowledge of the physical/spatial properties of an atom including orbital type and where the electrons are likely to be.
1. Application of this knowledge to explain physical properties of atoms and their reactivity (e.g., size, nuclear effective charge, electron affinities, ionization energy, ionization states, oxidation states, redox reactions)
2. Application of this knowledge to predict ionic vs. molecular bonds, polar vs. non-polar bonds
3. Application of this knowledge to predict Lewis structures, electronic & molecular geometry and formal charge, and polarity.
F. Knowledge of thermodynamics. Application of this knowledge to calculate enthalpies of chemical reactions (Hess’s Law).
G. Knowledge of how gases behave and the ability to apply this knowledge to perform calculations involving the ideal gas equation.
H. Knowledge of the intermolecular forces that govern the physical properties of liquids and solids. Application of this knowledge to rationalize differences in physical properties.
I. Knowledge of terms
that provide information related to concentration. Application
of this information to calculate molarity, molality, etc.
Summary: Most
target questions were answered correctly > 50% of the time when a
single principle was required. However, when more than one concept
was required to answer the question, the frequency of correct answers
dropped (for example see 6th question in Target A).
Targets to work on in future semesters include identifying which species
is oxidized and which is reduced, defining what is a state function?
what is an extensive property? what are the conditions for an ideal
gas? and providing examples of each.
Overall Summary:
Student evaluations were tallied and the table below summarizes comments:
Table of Student Evaluation responses
136 responses
What was positive?
36% WebCT quizzing was beneficial and preferred
26% liked having the lecture notes on-line ahead of time
other comments representing less than 10% of responses:
9/136 liked the Student Instructor (SI)
11/136 said instructor was well prepared
10/136 said they liked the explanations and examples given in class
What was negative?
16% had no comments under “what changes could be made”
13% said “slow down”
12% asked for more problems to be solved in class
13% asked for homework assignments that were graded to help their grade or something to motivate them to study
10% said class (lecture) was boring; suggestions ranged from using the I-clicker to handing out candy
other comments representing less than 10% of responses :
10/136 said that the test material didn’t
match the lecture and quiz material (it was harder)
Web CT was used extensively
in this class. On-line quizzing was well-received and was evaluated
by the students as a great learning tool. Posting of the lecture
notes on WebCT was also favored. Practice exams and keys were
available on WebCT and were used quite frequently. A discussion
board where students could post questions and the instructor would answer
them was popular especially the weekend before an exam. Exam mean
scores were consistently in the 64-68%, which was not popular with the
students. Students argued that the instructor needed to do something
to motivate them to study and requested additional homework assignments
that would be graded. However, homework assignments for a class
of 200 is not feasible. As an alternative, participation
in class (e.g., by use of the student adopted I-clicker) will be used
to increase the interaction in the classroom.
