Research 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)
Opportunities to Learn Mathematics for Teaching at MSU *Prerequisite: College Algebra
Design of Study • Cross-sectional Data Collection
Instruments 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
Coding 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
Detailed Look at Two Problems • Whole Numbers • There are 4 • We discuss Item W1 • Fractions • There are 5 • We discuss Item F4
Imagine that one of your students shows you the following strategy for subtracting wholenumbers: 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 * [Adapted from: Ball & Hill (2002). Cultivating knowledge for teaching mathematics: Early fall survey.Cultivating Teachers’ Knowledge for Teaching Mathematics Study. Ann Arbor, University of Michigan ] Whole Number Problem W1*
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.
Numeric Score Summary forW1 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
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 ).

Conclusions • 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 outperformedMATH-ED-S students, suggesting that preservice teachers do not retain all the knowledge and understanding gained in previous courses and tested by these tasks.
Next 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.)
