A Study of Core-Plus Students Attending Michigan State University

One measure of the effectiveness of a high school mathematics program is the success students have in subsequent university mathematics courses. As part of a large-scale study of Michigan students, we analyzed the records of students arriving at Michigan State University from four high schools which adopted the Core-Plus Mathematics program. Those students placed into, and enrolled in, increasingly lower level courses as the implementation progressed; the downward trend is statistically very robust (p < .0005). The grades these students earned in their university mathematics courses were also below average (p < .01). ACT scores suggested the existence but not the severity of these trends. Over the past two decades there has been a growing awareness of the inadequacy of the mathematical skills of American high school graduates. That was the assessment of the 1983 report A Nation at Risk [9]. Many subsequent studies point to the same conclusion. The most recent National Assessment of Educational Progress (NAEP) Report [2] concluded that only 17 percent of US twelfth graders were proficient at mathematics. International comparisons also indicate a relatively low level of mathematics achievement by US high school students. The Third International Mathematics and Science Study (TIMSS) assessed the ‘Mathematics Literacy’ of end-of -secondary students in 22 countries and found that US students statistically outperformed only two countries, Cyprus and South Africa [13]. Related studies suggest that the mathematics courses taken by American high school students are often at a lower level than those taken by their international peers, and that US high schools are offering a wide assortment of courses which lack the focus and coherence found in many foreign curricula [14]. This situation has been of particular concern on college and university campuses, where large numbers of students require remedial courses to bring their mathematical knowledge and skills up to what is required for college-level mathematics and science courses. One effort to improve school mathematics began in 1989 with the Curriculum and Evaluation Standards for School Mathematics published by the National Council of Teachers of Mathematics This statistic uses the notion of ‘proficient’, identified by the National Assessment Governing Board as the level that all students should reach.
