K-12 Mathematics: Some Warning Signs Professor Clifford Mass Department of Atmospheric Sciences University of Washington
Warning Sign One:Students Are Less Mathematically Capable in College Freshman Courses • Atmospheric Sciences 101 students today are clearly less math capable than 10-15 years ago. • Most have poor algebra skills. Many are uncomfortable with even simple equations. • As a result, we have had to “dumb-down” the class. • Other professors in a variety of disciplines have noticed the same thing.
Objective Evidence The UW Gave the Same Math Placement Exam Between 1990 and 1999 After Scores Plummeted…They Created a New EASIER Exam
Old Exam New (Easier)Exam
While Math Placement Scores Have Dropped, It Has Become More Difficult to Get Into the UW And Their High School Grade Point Averages Have Risen Considerably!
What is going on? • Are Washington State students getting dumber in mathematics? • Are external factors (video games, cell-phone usage, two-wage-earner families) taking a toll? • Could changes in math curricula be part of the story?
A Relevant Side Issue • Foreign-born and foreign-educated individuals are increasingly dominating the more mathematical disciplines. • Why aren’t their enough Americans to fill math-related positions?
1989: The National Council of Teachers of Mathematics (NTCM) Standards • Really more of a set of guidelines then true detailed standards. • Promote the discovery approach—students are led through exercises, experiments, and hands-on projects designed to motivate them to discover mathematical principles on their own. • Far less emphasis on proven algorithms (e.g., long division) and more emphasis on using calculators. • Less emphasis on acquiring mastery through practice. • Less emphasis on algebra and geometry. • Also known as reform math…or by some as fuzzy math!
A Range of New Curricula Sprung From the NCTM Standards • Examples include TERC Investigations, CMP, and the McDougal–Littell Integrated Math. • McDougal–Littell Integrated Math has been around for over a decade and was initiated in the Seattle Public Schools in the mid 90s—and is still in use.
McDougal–Littell Integrated Math. • Aside: Several math education professors at the UW agree that Integrated Math is substandard, but claimed it wasn’t “real” reform math. • Not too fast!!… the teacher’s edition of Integrated Math mentioned NCTM many times! • And the approach is clearly “reform” and fuzzy
My Sons’ Experience with McDougal–Littell Integrated Math • These books skip around topics in a frenzied way that makes mastery impossible. • They lack coherence and logical progression of ideas. • For my oldest son, I was so concerned about his lack of basic skills that I signed him up for Kumon Math, extra tutoring, and worked with him at night. And it worked!
And the Most Serious Problem! The meteorology examples are completely wrong!
IMP Math: Even Less Substance • My younger son in now taking Interactive Mathematics Program (IMP) • He is COMPLAINING to me that it is not challenging, that he wants to learn more. • Missing key mathematical elements. • Perhaps OK for someone who is not college-bound.
The Bottom Line • Whether the new “reform” curricula are contributing to the decline in Washington State student math performance is a matter of speculation. My own personal experience suggest that it is. • But what is clear, is that these curricula are inadequate to meet the needs of most of our children, including those interested in going into technical fields. • Ironically, the dominance of language in these texts will work against those with problems with expression and understanding English prose– i.e., will hurt those that need the most help.
Books and Curricula Matter • Learning occurs in many ways…and not all of it is in the classroom. • Some students are visual self-learners--who learn best on their home reading their books. • Parental interaction can be very important…but they must be able to understand and make use of the book. • Therefore, books must be self-contained as much as possible and not DEMAND extensive training for their application. • In contrast, most reform math texts require extensive teacher training and are not self-contained.
Whose Math Wars? • When some of us have pointed out our discomfort with some aspects of the current math education situation, supporters of the reform status quo, accuse us of igniting “math wars” --as if we are doing something aggressive and wrong. • We are simply looking to restore a balanced approach.
