REMINDER-THE ISSUE12TH GRADE MATH SCORES 2005
A CAUTIONARY NOTE
94% of workers reported using math on the job, but, only1
22% reported math “higher” than basic 19% reported using “Algebra 1” 9% reported using “Algebra 2”
Among upper level white collar workers1
30% reported using math up to Algebra 1 14% reported using math up to Algebra 2
Less than 5% of workers make extensive use of Algebra 2, Trigonometry, Calculus, or Geometry on the job2

TAKING MORE MATH IS NO GUARANTEE
43% of ACT-tested Class of 20051 who earned A or B grades in Algebra II did not meet ACT College Readiness Benchmarks in math (75% chance of earning a C or better; 50% chance of earning a B or better in college math)
25% who took more than 3 years of math did not meet Benchmarks in math
(NOTE: these data are only for those who took the ACT tests)
ACT, Inc. (2007) Rigor at Risk.
MATH-IN-CTEA study to test the possibility that enhancing the embedded mathematics in Technical Education coursework will build skills in this critical academic area without reducing technical skill development.

2. What we found
3. What we learned
WHY FOCUS ON CTE
CTE provides a math-rich context CTE curriculum/pedagogies do not
systematically emphasize math skill development
KEY QUESTIONS OF THE STUDY
Does enhancing the CTE curriculum with math increase math skills of CTE students?
Can we infuse enough math into CTE curricula to meaningfully enhance the academic skills of CTE participants (Perkins III Core Indicator)
Without reducing technical skill development

ELEMENT 1:
INTRODUCE THE AUTOMOTIVE LESSON
A student brought this problem to class:
He has installed super driving lights on a 12 volt system. His 15 amp fuse keepsblowing out. He has 0.4 Ohms of resistance.
ELEMENT 2:
FIND OUT WHAT STUDENTS KNOW: Discuss what they know about voltage,
amperes, and resistance.
Volt is a unit of electromotive force (E)Ampere is a unit of electrical current (I)Ohm is the unit of electrical resistance (R)
ELEMENT 2:
FIND OUT WHAT STUDENTS KNOW: What is an Ohm? Where did the name come from? Georg Ohm was a German physicist.
In 1827 he defined the fundamental relationship between voltage, current, and resistance.
Ohm’s Law: E = I R
ELEMENT 3:
WORK THROUGH THE EMBEDDED PROBLEM: The student has installed super
driving lights on a 12 volt system. His 15 amp fuse keeps blowing. He has 0.4 Ohms of resistance.
ELEMENT 3:
WORK THROUGH THE EMBEDDED PROBLEM: Continue bridging the automotive
and math vocabulary. The basic formula is:
E = I R
We know E (volts) and R (resistance).We need to find I (amps).
ELEMENT 3:
WORK THROUGH THE EMBEDDED PROBLEM: We need to isolate the variable. We do that by dividing IR by R, which
leaves I by itself. What you do to one side of the
equation you must do to the other...therefore E is alsodivided by R.
I = E / R
ELEMENT 3:
WORK THROUGH THE EMBEDDED PROBLEM:
I = E / R
I = 12 / 0.4
I = 30 amps
The student needs a 30 amp fuse to handle the lights.
ELEMENT 4:
WORK THROUGH RELATED, CONTEXTUAL EXAMPLES A 1998 Ford F-150 needs 180
starting amps to crank the engine. What is the resistance if the voltage is 12v?
R = E / I
R = 12 / 180
R = .066... Ohms
ELEMENT 4:
WORK THROUGH RELATED, CONTEXTUAL EXAMPLES If the resistance in the rear tail light
is 1.8 Ohms and the voltage equals 12v, what is the amperage?
I = E / R
I = 12 / 1.8
I = 6.66 amps
ELEMENT 4:
WORK THROUGH RELATED, CONTEXTUAL EXAMPLES
A 100-amp alternator has 0.12 Ohms of resistance. What must the voltage equal?
E = I R
E = 100(0.12)
E = 12 volts
ELEMENT 5:
WORK THROUGH TRADITIONAL MATH EXAMPLES The formula for area of a rectangle is A = LW
where A is the area, L is the length and W is the width.
Find the area of a rectangle that has a length of 8 ft. and an area of 120 sq. ft.
A / L = W120 sq ft / 8 ft = W15ft = W
ELEMENT 5:
WORK THROUGH TRADITIONAL MATH EXAMPLES The formula for distance is D = RT where D is the
distance, R is the rate of speed in mph and T is the time in hours.
If a car is traveling at an average speed of 55 mph and you travel 385 miles, how long did the trip take?
D = RTT = D / RT = 385 / 55 mphT = 7 hours
ELEMENT 6:
STUDENTS DEMONSTRATE UNDERSTANDING
Students now given opportunities to work on similar problems using this concept:
HomeworkTeam/group workProject work
ELEMENT 6:
STUDENTS DEMONSTRATE UNDERSTANDING
A vehicle with a 12 volt system and a 100 amp alternator has the following circuits:
30 amp a/c heater30 amp power window/seat15 amp exterior lighting10 amp radio7.5 amp interior lighting
1. Find the total resistance of the entire electrical system based on the above information.
2. Find the unused amperage if all of the above circuits are active.
ELEMENT 7:
FORMAL ASSESSMENT
Include math questions in formal assessments... both embedded problems and traditional problems that emphasize the importance of math to automotive technology.

DOES ENHANCING MATH IN CTE
Affect Technical Skill Development?
NO!
REPLICATING THE MATH-IN-CTE MODEL:CORE PRINCIPLES
A. Develop and sustain a community of practice
B. Begin with the CTE curriculum and not with the math curriculum
C. Understand math as essential workplace skill
D. Maximize the math in CTE curriculaE. CTE teachers are teachers of “math-in-
CTE” NOT math teachers
FINAL THOUGHTS: MATH-IN-CTE
A powerful, evidence based strategy for improving math skills of students;
A way but not THE way to help high school students master math
(other approaches – NY BOCES) Not a substitute for traditional math
courses Lab for mastering what many
students learn but don’t understand Will not fix all your math problems
