The research reported in this paper was supported in part by the National Science Foundation #REC-9553889 and #REC-0087511 and by the Wisconsin Center for Education Research, School of Education, University of Wisconsin-Madison and the Northern Illinois University. The views expressed here are those of the authors and do not necessarily reflect the views of the funding agency.
Introduction
The purposes of the longitudinal/cross-sectional study of the impact of Mathematics in Context (MiC; National Center for Research in Mathematical Sciences Education & Freudenthal Institute, 1997–1998) on student performance are (a) to determine the mathematical knowledge, understanding, attitudes, and levels of student performance as a consequence of studying MiC for over three years; and (b) to compare student knowledge, understanding, attitudes, and levels of performance of students using MiC with those using conventional mathematics curricula. The research model for this study is an adaptation of a structural model for monitoring changes in school mathematics (Romberg, 1987). For this study, information is being gathered on 14 variables over a 3-year period for three groups of students (those in Grades 5, 6, and 7 in 1997). The variables have been organized in five categories (prior, independent, intervening, outcome, and consequent). (See Figure 1 for variables and hypothesized relationships.)

Overview The data in this Technical Report contain the general results for the eight grade-level-by-year studies shown as white ellipses in Figure 2. The summary data has been derived from each student’s weighted item scores on the Classroom Achievement Index (CA) (see Appendix A).

In each case the summary data has been displayed in terms of Tables that include the number of students, mean, standard deviation, both lower and upper 95% confidence intervals, and score distributions for the 95%tile, 75%tile, 25%tile, and 5%tile, then a Progress Map has been constructed to portray that data.1
The following Tables and Maps have been organized in terms of each of the eight year-by-grade studies. Within each study the data on student performance is then organized first across all districts, second for each district separately, and then by teachers within districts.
1 Progress Maps were not made if N < 10.

The purposes of the longitudinal/cross-sectional study of the impact of Mathematics in Context (MiC) on student performance were (a) to determine the mathematical knowledge, understanding, attitudes, and levels of student performance as a consequence of studying MiC for over three years; and (b) to compare student knowledge, understanding, attitudes, and levels of performance of students using MiC with those using conventional mathematics curricula. The research model for this study was an adaptation of a structural model for monitoring changes in school mathematics (Romberg, 1987, described in Chapter 2). The outcome variables for this model are - knowledge and understanding, and application. For analytic purposes we assumed that variation in classroom achievement based on the measures developed for these variables can be captured in progress maps for classroom achievement. There were three questions that the study was designed to answer: 1. What is the impact of the MiC instructional approach on student performance? 2. How is this impact different from that of traditional instruction on students performance? 3. What variables associated with classroom instruction account for variation in student
performance? To answer these questions an analysis plan involving seven steps has been planned. Step One: Creating an Overall Progress Map The dependent variable used to answer each of the questions is an index of “Classroom Achievement (CA)” derived from data from student responses to eight tests {four External Assessments (EA) based on NAEP and TIMSS items, and four Problem Solving Assessments (PSA) developed by the staff of the Freudenthal Institute. One form of each test was given to students at each of the grades 5, 6, 7 and 8. From the raw scores on these tests the CA index was derived by the research team at the Australian Council for Educational Research (ACER) using “Rasch measurement models” that allow one to combine information from different tests administered at different times onto a single scale. The product of this step is a single CA scale. Step Two: Answering Question #1 – Grade-Level-by-Year As shown in Figure 1, the overall study involves seventeen studies: eight grade-level-by year studies that can be related for cross-sectional comparisons, three cross-grade studies, three cross-year studies, and three longitudinal comparisons.

To answer “Question 1” the CA index was used to examine the performance of all MiC students in the four sites at each grade level (the eight grade-level-by-year descriptions of performance of all MiC students). Comparisons of performance on CA then was derived for the different sites, classes, teachers, gender of students, ethnicity of students, etc. Step Three: Answering Question #1 – Cross-Grade, Cross-Year From the analyses done in Step Two we made the three cross-grade comparisons, and the three cross-year cross-sectional studies indicated in Figure 1. These comparisons yield pictures of general student progress in performance as a consequence of instruction using MiC. Step Four: Answering Question #1 – Longitudinally Next we examined the three longitudinal descriptions also shown in Figure 1. However, since the student data-base must be restricted to those MiC students that participated in two or three years of the study (study transiency was high), several cohorts of students examined over the two (or three) years with respect to the overall index (CA). Step Five: Answering Question #2 To answer Question 2 only the MiC data from the two sites where similar data from students in classes using conventional instructional materials was gathered. The comparisions were with respect to the eight grade-level-by-year studies, followed by the cross-grade, cross-year, and longitudinal comparisions. Step Six: Answering Question #3 – Creating Composite Indices Data for both MiC and conventional students at the two sites were used to examine the relationship between variation in classroom achievement (CA), aggregated by strand, test, or total performance can be attributed to variations in opportunity to learn with understanding (OTLu), preceding achievement (PA), method of instruction (I), and school context (SC).

Step Seven: Answering Question #3 – Analyses Since indices for each of these composite variables was constructed three different analyses were planned. First, for the grade-level-by-year studies we compared similar groups of students on CA. Second, linear regression was used to examine this relationship for the eight grade-level-by-year studies. Third, since the composite variables were constructed from several sources that reflect the original 14 variables structural model, we calculated path coefficients relating most of the variables in the model using structural equations.
