A
lot has occurred since I issued this preliminary report one year ago.First
and foremost, Professor R. James Milgram of Stanford University completed
an analysis of my data.His report
is entitled “Outcomes Analysis for Core Plus Students
at Andover High School: One Year Later”, and it was issued around January
of this year.The “One Year Later”
refers to the fact that I surveyed the graduates of Andover and Lahser
High Schools one year after they had graduated.Appendix
6 in his report, which is of more recent vintage, gives the ACT scores
of Andover students and compares them with Lahser students and other groups
of students.
I
want to emphasize that Professor Milgram used the actual data I collected
(minus the names) and not the “Comments in Context” which I had in my original
report and which were extracted from the data[2].Subsequently,
the following column by Debra Saunders appeared in the March 12 edition
of The San Francisco Chronicle:[3]
“High
School Students and Lab Rats”
MELISSA
LYNN was shocked when she discovered that she placed in the bottom 1 percent
of the University of Michigan math placement test. She had graduated from
the affluent high-achieving Andover High School in Bloomfield Hills, Mich.,
with a 3.97 grade point average and A's in math.
Lynn
blames Core Plus, an experimental math program -- with an emphasis on writing
about math and working in groups -- funded by the National Science Foundation.
``It had very good intentions and wanted you to apply real principles to
real life scenarios, but it was missing the crucial element of algebra,
'' Lynn said yesterday.Gregory
Bachelis, a math professor at Wayne State University and parent of a student
in Lynn's school district[4],
wanted to know if Lynn's experience was typical. He decided to do his own
survey. He sent questionnaires to all 1997 graduates of Andover and the
other Bloomfield Hills high school, Lahser, which has similar demographics
but a traditional math program.
Bachelis
heard from 112 out of 228 Andover grads, 67 of whom were Core Plus alumni;
30 percent of Lahser students responded.R.
James Milgram, a mathematics professor at Stanford University, has written
a paper on Bachelis' findings. Milgram found the following.
--
Only two Core Plus grads (out of 67) reported taking calculus in their
first year of college, 11 out of a similar group of 41 Lahser grads took
calculus; 46 Core Plussers ended up in remedial math, compared to 18 Lahser
grads.
--
The average math GPA for the Core Plus grads was 1.9, 2.6 for Lahser students.
--
The average SAT Math score for Lahser grads was 59 points higher than Core
Plus.
As
one Core Plus survivor who was placed in remedial math wrote, ``I am the
epitome of mathematical ignorance in a Top 10 high school in the country
with a 4.0 in math.'' Student comments paint a picture of students who
worked hard but foundered in college math. Andover Principal John Toma
takes great exception with the study. He attacked Bachelis' bias. Bachelis
was a critic of trendy math before the survey. Asked about Melissa Lynn,
Toma responded, that the University of Michigan ``admits that they're going
to change the placement exam because it's flat out outdated.''
Andover
allows students to opt out of Core Plus. Only 55 out of 840 do so, which
shows that someone must like Core Plus. Although Lynn says she didn't opt
out because she would have had to take a bus to Lahser for math and that
conflicted with her schedule.
Toma
noted that studies should not rely on students to give their SAT scores
and grades, that the more reliable studies get that data directly.He
sent me a University of Michigan memo that reportedly checked grades and
found that ``reform'' math students scored ``nearly half a grade higher``
than traditional math grads. But the survey failed to differentiate between
reform students and non-reform students, lumped them by school, provided
no specific GPAs, no school names and no number of students tested -- it
lacks credibility.
That
is not to say that the Bachelis/Milgram study is without problems. It could
be that only the angrier kids responded. Some may have misstated their
scores.
Still,
the anguish that one reads in the student comments should not be ignored.
``I cannot even do basic math calculations,'' wrote one grad.Wrote
another: ``Although I did well in high school math, I feel I don't understand
basic math concepts well enough to keep up in college.'' Some had to take
math courses for which they could not even receive college credit.
Milgram
is most appalled at the ethics behind Andover's math experiment. He believes
that parents should have been warned and students given more opportunity
to get out. Instead, public schools too frequently give students about
as much choice as lab rats have. None.

the Detroit Free Press has the option of carrying Saunders’ columns, they

NEW
MATH DOESN'T COMPUTE WITH STUDENTS, SURVEY FINDS
It
inflames national debate on memorization vs. critical analysis
BY
TAMARA AUDI Free Press Staff Writer
The
latest strike in the war between new and traditional math has hit Bloomfield
Hills in the form of a fiercely disputed survey.
A
study released by a Stanford University professor shows that students who
were enrolled in the Bloomfield Hills district's Core Plus program --the
math curriculum that emphasizes critical thinking over traditional memorization
-- are having problems succeeding in math in college.
The
Core Plus program is used, in varying forms, at roughly 80 Michigan schools
-- including Southfield-Lathrup and West Bloomfield high schools -- and
in 200 schools nationally.
"The
study represents the first glimpse, to the best of our knowledge, of how
students trained in this new way perform in a university environment, and,
frankly, the results are not encouraging," Stanford's R. James Milgram
wrote in a forward to the survey.Researchers
questioned[6]
67 Andover High School graduates who had been enrolled in Core Plus for
four years, and compared them to 41 graduates who studied traditional math
programs at Lahser, the district's other high school.
Among
the findings:
46
Core Plus graduates enrolled in remedial math in college, compared to 18
traditional math students.
The
average college math grade-point average for the Core Plus grads was 1.9,
compared to 2.6 for traditional math students.
Core
Plus graduates also had a lower average score on the math part of the SAT
than traditional students.
But
the study has been called biased by local educators and Core Plus developers.
"It's
a trash study," said Bloomfield Hills school board president Mindy Nathan,
who said her daughter's math skills have improved because of Core Plus.
"They went after kids they knew were dissatisfied."
Nathan
and others say the study is part of a nationwide political movement to
stop math reform.
Christian
Hirsch, the director of the Core Plus Mathematics Project at Western Michigan
University, said the Stanford study is suspect because it is based on self-reporting
by students, not official school records.
In
addition, Hirsch said, Core Plus has included more traditional elements
of math since 1997.
The
study has sparked a national debate on math reform. Almost as soon as the
study was posted on the Internet last month, its results were trumpeted
on a Web site run by Mathematically Correct, a San Diego-based parent group
opposed to Core Plus.
Core
Plus proponents hit back with a Web site of their own. Proponents noted
other studies that showed Core Plus students out-performed traditional
math students on at least two standardized national tests.
The
conflicting information has left local school districts hungry for an objective
assessment.
West
Bloomfield Superintendent Seymour Gretchko said: "The university community
is split, the parents are split. But we'd be anxious to see any data that
are out there."
The
Stanford study is available on the Internet at ftp://math.stanford.edu/pub/papers/milgram/andover-report.htm

Needless to say, Mindy Nathan had no evidence to back up her charges.I sent the report to Gary Doyle, the superintendent of BHSD, but as far as I know, the Board never discussed it at any of their meetings, nor did Doyle ever retract his earlier statement: “Our community and our educators have been maligned and I think we have the right to see the complete information," after he had seen the report.[7][8]The Core Plus directors did respond to my report and Milgram’s analysis, as well as to Saunders’ column reprinted above, in The Bachelis-Milgram Study at a Michigan High School is Seriously Flawed and Draws Invalid Conclusions and When Political Agendas Get in the Way of the Facts....
They make the point that the sample was self-selected.True enough.I tried to get every one of the year 1997 graduates of Andover and Lahser High Schools for which I had valid addresses to respond to my survey.Only those responded that chose to do so; I had no way of forcing them to.So does that invalidate the responses of the 50% of the Andover graduates who replied, or the 30% of the Lahser graduates?The Core-Plus directors also state that less than 40% of the Andover Core-Plus students responded to the survey.I do not know how they arrived at that figure.[9]
As for the way the SAT and ACT scores were reported
in the “Comments in Context”, I converted the date to intervals to help
preserve confidentiality, as I explained at the time.As
I said above, Professor Milgram had access to the actual data.
I
have decided not to respond to the personal attacks of Hirsch & Co.impugning
my integrity.
As for the current
situation at Andover High School, we have the following article which appeared
in the August 29 edition of the Traverse City Record-Eagle:
Record-Eagle staff writer
TRAVERSE CITY - When it comes to measuring the effects of Core Math, Bloomfield
Hills offers both test and control groups.
The school district has two nationally
ranked high schools - Andover and Lahser.
Andover adopted the Core-Plus Math Project
curriculum in 1993. Lahser stuck with traditional math.
This wealthy Detroit suburb also has
seen the most heated debate in Michigan over the idea of reform math.
"I'd call it a full-fledged controversy,"
Andover Principal John Toma said.
The first class of Core students graduated
in 1997 with more than 90 percent going on to college.
Conflicting studies evaluated the effectiveness
of Core for those first graduates and did nothing to settle the community
debate.
And so, Andover began offering an alternative
to Core Math in the 1998-99 school year.
About 100 of 900 students opted out
of Core then. About 150 will this year, Toma said.
"We are running dual curriculum," Toma
said. "In three to five years, I'd like to see only one program that borrows
from each.
"The traditional are going to move toward
integration. The integration people are going to go toward the traditional.
I believe we will end up somewhere in the middle and that will be best
for everybody."
This already is starting to happen,
Toma said.
Like other Core-Plus schools, Andover
has placed increasing importance on developing basic algebra skills.
At Lahser, they've started using graphing
calculators.
The debate over Core Math in Bloomfield
Hills and Traverse City are not the only ones. Similar disputes have surfaced
in Alaska, California and Texas.
The debates, however, are still isolated
incidents, said Christian Hirsch, director of the Core-Plus Mathematics
Project.
"It certainly hasn't happened everywhere
Core-Plus is," he said.
I
find Hirsch’s remarks about “isolated incidents” to be rather ironic.Apparently
his evaluation process, headed by co-director Harold Schoen, does not include
surveying Core Plus alumni after they have been out of the high school
“nest” for one year, as my survey did; so how does he know whether the
results of my survey are representative or not?I
should add that I was not paid anything for the six months I worked on
the survey, except for reimbursement for the stamps on the return envelopes.
I
mention in closing that the West Bloomfield School District, where I live,
has abandoned Core-Plus in favor of a three year Integrated Math sequence
from McDougal Littell, written by Rubenstein et al, to be followed
by a pre-calculus text, as yet to be chosen.
“Gary shared a recent article
about modifications to the math program at Michigan State University.MSU
has experienced a more than 20 percent freshman failure rate in mathematics,
and reform math at the high school level is frequently cited as the cause.Gary
said this is not true – MSU has had this problem far longer than reform
math has been around.Gary congratulated
MSU on finally changing their math program, noting that their math program
has been about 20 years behind the times.” [Emphasis added.]
