9Research Question
- What do prospective elementary teachers learn
about mathematics and students mathematical
thinking in their mathematics and mathematics
education courses at MSU? - Two content domains
- Numbers and operations (preliminary report today)
- Geometry and measurement (data not yet analyzed)
10Opportunities to Learn Mathematics for Teaching
at MSU
Prerequisite College Algebra
11Design of Study
- Cross-sectional Data Collection
12Instruments Used
- Extended written tasks Whole numbers and
fractions - Completed in-class
- MATH post-test tasks embedded in final exam
- In all other cases, tasks did not count as part
of course grade - In both high-stakes and low-stakes situations,
instructor observation suggests all tests were
taken seriously
13Coding and Scoring
- Scoring rubrics developed iteratively by an
interdisciplinary research team consisting of
faculty and graduate students from the
Departments of Mathematics and Teacher Education. - Maximum number of points varied per task
14Detailed Look at Two Problems
- Whole Numbers
- There are 4
- We discuss Item W1
- Fractions
- There are 5
- We discuss Item F4
15Whole Number Problem W1
- Imagine that one of your students shows you the
following strategy for subtracting whole numbers - 37
- - 19
- - 2
- 20
- 18
- W1a. Do you think that this strategy will work
for any two whole numbers? - Yes No I don't know
- W1b. How do you think the student would use this
strategy on the problem below? - 423
- 167

16Types of Responses for W1b
17Types of Responses for W1b
18- To compare performance across problems a
standardized measure was computed - Difficulty Index mean / (max. no. of points)
- Index ranges from 0 to 1.
- 0 means nobody got the problem correct
- 1 means everybody got the problem correct.
19Numeric Score Summary for W1
W1a. Do you think that this strategy will work
for any two whole numbers?
W1b. How do you think the student would use this
strategy on the problem below? 423 167
20Fraction Problem - F4
- Suppose that one serving of rice is two-thirds of
a cup. - How many servings are in 4 cups of rice?
- (a) Show how to solve this problem by drawing a
diagram. - (b) Show how to solve this problem by calculating
the value of a numerical expression. - Adapted from Beckmann, S. (2002 ).

29Conclusions
- Performance of MATH students improved
dramatically during the semester. Levels of
performance on fraction tasks, in particular, are
considerably higher than that of elementary
teachers involved in other studies, e.g. Ma
(1999). - On the pretests, MATH-ED-S students outperformed
the MATH students, suggesting that preservice
teachers retain some knowledge gained in MATH
courses. - On the posttests, MATH students outperformed
MATH-ED-S students, suggesting that preservice
teachers do not retain all the knowledge and
understanding gained in previous courses and
tested by these tasks.
30Next Steps
- Complete analyses of remaining problems about
number - Analyze data on geometry measurement collected
in Math 2 - Follow up with longitudinal study of original
MATH 1 samples. - Share results with instructors in MATH and
MATH-ED courses. - Coordinate curricula of MATH and MATH-ED courses.
- Design new instructional activities, as needed,
for MATH and MATH-ED courses. - Share results with professional colleagues.
- Collect data from practicing teachers. (Perhaps
this is another study.)
