Slide 3 3 In my view, (Vote for ONE:) In helping students succeed in first -year chem, the math background of entering students is: A. A major problem B. A minor problem C. Not a problem Good Afternoon. My slides today, with plenty of references, are posted on the web. I will cover just selected slides, but I will put up the web address at the end where you may view the slides with additional detail if you find any of them interesting. Could I ask: How many of you frequently teach any form of first year college chemistry? Anyone teach High School or AP chemistry? My focus today is going to be on calculations in those courses. I’d like to start by asking you to please read the question on this slide -- then be ready to vote for A, B, or C. Ready? How many of you would vote raise your hand. for A, ________ B? ______ C? _______ (Voting audience was 100% major)

Slide 10 10 Virginia Math Results: VA all students Grade 9 1998 1999 2000 2001 2002 Total Math 54 55 55 55 55 • Stanford 9 standardized test given statewide • National percentile average = 50 on 1995 norms My goal today is to look at the evidence. Is math preparation is a problem? If so, WHY? And how can we fix the problem? About 8 years ago, I was asked to represent my Virginia faculty organization On a task force looking at the issue Of why so many students entering college were needing remediation. Being a chem instructor, I thought the problem was the K-12 math programs But when I looked at the standardized tests, in “Total Math” Virginia scores were above average – average being the 50th percentile -- and steady. (point) But when I looked in the report detail, I found that on the test VA was using
