Some things that seem to be having an effect on student success and =
ability is addressing the problem "Johnny Can't Read" by expecting =
Johnny to read and helping Johnny read mathematics rather than try to =
make math accessible without reading.
I focus on language in many ways. In Basic Mathematics, my skills-based =
worksheets and quizzes include many questions asked in words--like "Find =
the sum of - 9 and 3.85." "Give an example, if possible, where the =
product of 4 negative numbers and 3 positive numbers is negative. If =
not possible, explain why not." I have students answer questions about =
a chapter before we cover the chapter. The questions require some =
interpretation beyond copying a definition from the book. For example, =
"What is the associative law for multiplication? Demonstrate the law =
with the numbers 8, 22, and 17." Another example of a preview question =
is "On the following grid, plot 5 points that lie on the x-axis and =
write both coordinates of each point you plotted." Then the next =
question is, "What do the coordinates of the five points have in =
common?" The next question is, "What is an x-intercept of a line? =
Which coordinate of an x-intercept is zero?"
In Basic Math and Beginning Algebra, such techniques are very helpful. =
It is harder in Intermediate Algebra because students tend to try to =
answer questions without reading and fill in answers from their memories =
which is frequently muddled. I think I am going to start requiring them =
to write the page number of the text where they found the answer.
Another technique that seems to work with learning skills is competency =
testing. My students get a number of 20-point (generally 5 questions) =
quizzes during the semester that are skills-based. I do not give =
partial credit when grading a problem and the students have to make 80% =
or higher to get credit for the quiz. If they do not meet the =
competency, they have to rework the quiz and have it checked off by me =
or a tutor in the math lab before taking a replacement quiz. A student =
must make an 80% average on all of the quizzes to make a C or higher in =
the class. (On the first retake--or if a student missed the quiz--the =
maximum score is 90%, after that it is 80%. The grade penalty for =
retakes seems to cut down on students missing on quiz day and on =
students trying the second time before they understand the material.)
Many hands-on activities are helpful. I tried a new one this semester =
in Beginning Algebra that I picked up at an NCTM-regional conference. =
Students who wanted to draw a picture did so and I copied the pictures =
on a transparanciy which I clipped to a sheet of graph paper with the =
axes marked through the center of the paper. Each group of students got =
a picture and had to identify enough points on the picture to render a =
decent duplication of the drawing. (They gave a sequence of points and =
wrote STOP when there was a break in the drawing, then picked up with =
the next sequence of points.) I had extra drawings for groups who =
finished early. Then the groups exchanged sequences of points and =
plotted the points to reproduce the picture. I had them draw the =
reproduced picture on a transparancy. Then we overlayed the reproduced =
picture on the original to see how well the groups did--by the way, very =
few points that were off. I particularly liked the activity because =
students got a lot of practice plotting points. They also dealt with =
points that had decimal and/or negative coordinates without particular =
difficulty. Having them plot that many points would have been an =
exceedingly boring task attached to no purpose the students could see. =
My students in that class have learned graphing better than my previous =
classes.

1. I have been very pleased with the students' comments regarding =

2. I had several students come up to me, after I dismissed the =
class, and tell me how much better they are doing in math because of the =
way we are presenting the material, and I think, because of what =
material we are presenting. We try to use a great deal of hands-on =

students are very involved in the lessons. In the courses we teach for =
non-math intensive AA and AAS degrees, the content is carefully selected =

algebraic manipulation-rather, it is on problem solving, understanding =
the solution and selecting the appropriate tools for solving the =
problem. For example, two students (older ladies) came up to me after a =
Mathematical Models class. They both said how much they understood slope =

were used to show how meaningful slope is in so many applications. They =
said that the definition of slope had been drilled into them in high =
school, but they never understood it before. They said they were very =
glad that we were changing the way mathematics is taught--making it more =

they agreed that they would see a great many word problems in their =
