Project Description: The Delta College (Michigan) mathematics
department conducted a course assessment project in Elementary Algebra
(MTH 097). Here are some characteristics of the course:
-
MTH 097 is a developmental mathematics course. Its
content parallels a traditional (early) high school first-year algebra
course.
-
MTH 097 is Delta College's most popular mathematics
course, followed closely by Prealgebra (MTH 096). In 2005-2006, about
1200 students enrolled in MTH 097 (59 sections) during the fall and
winter semesters.
-
The prerequisites of MTH 097 are either a C grade
or higher in Prealgebra (MTH 096) or a suitable COMPASS placement
score. About 39% of the MTH 097 students (n = 1186) took the prerequisite
course, MTH 096. About 61% did not take MTH 096.
A core set of common final exam questions was administered to all sections
of MTH 097 at the end of the Fall, 2004 and Winter, 2005 semesters.
The assessment questions the mathematics department wanted to address
are as follows:
-
Have MTH 097 students achieved the outcomes of the
course as measured by final exam questions?
-
Does MTH 096 (the prerequisite course) sufficiently
prepare students to succeed in MTH 097? What grade should students
receive in MTH 096 so that they are successful in MTH 097?
-
Based on their responses to the final exam questions,
what can we learn about our students learning in elementary algebra?

Construct the graph of a line if given the equation
of the line.

Identify an appropriate scale for both axes when
constructing a graph.
-
Set up an equation or expression if given a word phrase.
-
Solve a variety of real world problems using the tools
of algebra and mathematical modeling.
2. DESIGN assessment tools,
criteria and standards directly linked to each outcome.
There were 14 questions that each faculty member added to
their final exam. Some faculty members used only these questions as their
final exam. Others attached these 14 questions to the back of their longer
final exam. And yet others cut and pasted these 14 items into their final
exam to make a more coherent exam.
For the purposes of this assessment project, the student
responses were scored correct or incorrect.
Our standard was set to be 75%. That is, we would be happy
if 75% of all students taking the final exam would answer correctly each
of the common final exam questions.
3. IMPLEMENT assessment tool(s)
to gather evidence of student learning.
The common final exam questions were administered to all
sections of MTH 097 (Elementary Algebra) during the Fall, 2004 and Winter,
2005 semesters.
Each (full and part time) faculty member was sent a spreadsheet
for their section(s) listing each student and each common final exam question,
and was asked to complete the spreadsheet as follows: a 1 was entered
when a problem was completely correct, and a 0 was entered when the problem
was not correct. For the purposes of the assessment project, partial credit
was not awarded.

collected data.

Additional
Summary Tables: The data were analyzed in several ways. Group
comparisons, item analysis, impact of prerequisite course, and relationship
between reading placement score and success in course were all considered
to try to make sense of the data.
5. IDENTIFY gaps between desired
and actual results.
The data revealed several gaps between the actual and desired
results.
-
Only the A students achieved the 75% standard
for the most part. A students achieved the 75% standard on
14 of the 17 common final exam questions.
-
Students who earned less than an A grade in
MTH 097 achieved the 75% standard on only one of the common final
exam questions.
Clearly, we were hoping that the 75% standard would be achieved for
all exam questions for all successful students (students who earn an
A-C grade).
In our department discussions on the gap between desired and actual
results, we noted the following:
-
If partial credit was given, students would have scored
much higher. It was clear that many students did lots of correct mathematics
on their way to their final incorrect answer.
-
Student algebraic skills and understandings are very
fragile after completing the elementary algebra course. It may require
several additional semesters in college-level mathematics courses
before students master algebra.
-
A multiple choice format may have lead to additional
correct answers and higher scores.
- Because MTH 097 is a developmental course that does not count toward
graduation, it is the lowest priority course for students with several
courses; it is the first course that students will drop if they encounter
one of the many unexpected events that they will experience in their
work or personal life.
-
Students who take a similar course in high school
(or junior high) have an entire year, or 180 days, to learn the skills
and concepts of an elementary algebra course. We require students
to learn the course content in one semester, or 45 hours. Perhaps
the pace of this course is too fast for most students.
-
Because of the gap between how students score on the
common final exam questions and the grades student receive in the
course, some wonder if grade inflation is an issue.
-
Most of our students who are successful in our elementary
algebra course go on to be successful in Intermediate Algebra, other
math courses, or courses with an elementary algebra prerequisite.
So we should be concerned, but not overly concerned about our students'
performances on the common final.
6. DOCUMENT results and outline
needed changes in curriculum, instructional materials or teaching strategies.
The elementary algebra course has the lowest success rate
of any of the mathematics courses. Only about 55% of students who begin
the course will pass with a C or better. This assessment project confirms
that the course is not as successful as the mathematics faculty would
hope. In addition, students who passed elementary algebra are leaving
with very fragile algebra skills. Additional data collection revealed
that only 30% of Elementary Algebra C students passed Intermediate
Algebra.
So, what are we going to do about it?
During the department discussions the following proposals
were made:
- Offer an extended elementary algebra course that would contain the
same outcomes as elementary algebra, but would meet for one additional
hour per week.
- Offer a two course sequence of elementary algebra, each worth 1.5
credits each. The first module would contain the first half of the elementary
algebra course, and the second module would contain the second half
of the elementary algebra course.
- Make better use of the College's peer mentor program and assign peer
mentors to more of the elementary algebra sections.
- Experiment with higher prerequisites in elementary algebra or intermediate
algebra.
- Offer a couple of sections of the course so that they span an entire
year.
- Experiment with a continuous review model to teaching the course.
That is, assess students on the most important topics, skills, and concepts
several times during the semester after they are first introduced.
- Create an extended hour intermediate algebra course to accommodate
students who need additional time to master the course content.
The mathematics division decided to take the following actions:
- Experiment with alternate teaching strategies to help students develop
the algebra skills necessary to be successful in future courses.
- Create an extended-hour (6 contact hours) intermediate algebra course.
The prerequisite of this course is C or better in elementary
algebra.
- Increase the prerequisite of the 4-credit intermediate algebra course
to B- grade or better in elementary algebra.
