What do we know about CTE?
  • There is evidence that
  • CTE does not limit postsecondary education
  • Math and science course taking by CTE students is
    increasing amount and complexity
  • CTE as a function of the HS experience reduces
    the probability of dropping out of school
  • CTE is an economic value to the individual and
    the community (ROI)
  • It is possible to major in CTE and Academics
  • One conclusion is that A decade of reform
    (Perkins II III, STWOA various state efforts)
    is beginning to have an effect
  • but . . . achievement and transition
  • are the challenges put forth. . .

The Problem Math PerformanceOf American Youth
NAEP Scores for 17 Year olds
8
The number of 17-year-old students taking
advanced math classes has also increased -- with
17 percent studying calculus and 53 percent
studying second-year algebra --  it is unclear
why that trend has not resulted in higher average
math scores over all.

Why Focus on CTE - I
  • Students earn more credits in CTE than in math or
    science
  • 97 take at least one course
  • Nearly half earn at least 3 Specific Labor Market
    (SLMP) credits
  • One-quarter are
  • concentrators

Why Focus on CTE II
Levesque, K. (2003). Public High School Graduates
Who Participated in Vocational/Technical Education
11
Why Focus on CTE - III
  • CTE provides a math-rich context
  • CTE curriculum/pedagogies do not systematically
    emphasize math skill development

12
Alternative CTE Math Improvement Strategies
  • Related Math class(e.g., Business math)
  • Applied Math class (e.g., Tech Prep math)
  • Pull out math classeswith math teacher
  • Math teacher team teaches in CTE class
  • The NRCCTC, Math-in-CTE model-a research based
    approach to improving math skills
  • Note while some of these may improve math
    skills of students, the evidence is lacking.

13
Math-in-CTE
  • A 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.

14
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
  • What works?

15
Study Design Key Features
  • Random assignment of teachers to experimental or
    control condition
  • Five simultaneous study replications
  • Three measures of math skills (applied,
    traditional, college placement)
  • Multi-method quantitative and qualitative
  • Focus of the experimental intervention was
    naturally occurring math (embedded in curriculum)
  • A model of Curriculum Integration
  • Intense focus on Fidelity of Treatment

16
Focus of Math Interventions
  • Higher Level Math

    content (V-Tecs, AYES, MarkED, state guides, last
    years maps)
  • Create map for the school year
  • Align map with planned curriculum for the year
    (scope sequence)

Larrys Truck Improvements
  • Larry put a 6 lift kit on his Ford F-150 and a
    set of 33s Super Swamper Thornbird Tires
  • The Suspension System has been modified but the
    Brake System has not.
  • Do You See Any Problems?

GIT-R-DONE
29
What Parts Control the Stopping of the Truck?
  • Master Cylinder
  • Brake Hoses/Lines
  • Wheel Cylinders
  • Brake Calipers

30
Larry has a Problem!
  • What changes could you make to fix the problem?
  • Bigger parts
  • Such as Master Cylinder, Brake lines, Wheel
    Cylinders, and/or Brake Calipers

31
Pascals LawUnlock the mechanics of the
Hydraulic Braking System
32
Before we apply Pascals Law
  • We must first review and be familiar with
  • Diameter of a Piston
  • Radius of the Piston
  • Area of the top surface of the Piston
  • Mathematically speaking
  • Diameter The width of a circular or cylindrical
    object.
  • Radius The radius of a circle is half the
    diameter
  • Area Any particular extent of space or surface

33
Pascals Law
  • In the 1600's, the French scientist Blaise Pascal
    discovered a fact now known as Pascal's Law. It
    states that pressure at any point in a body of
    fluid is the same in every direction, exerting
    equal force on equal areas. This works for gases
    and liquids (both are fluids).

34
Pascals Formula
  • This brings us to a very important formula
  • P Pressure, F Force and A Area
  • This expresses that Pressure is Force per Unit
    Area. This is why pressure is usually expressed
    in pounds per square inch (psi).

36
Alices Areas
  • Your patient, Alice, came into the Emergency
    Department with partial and full thickness burns
    to her entire right (R) leg after falling into a
    camp fire. You are to calculate the area of the
    burn and determine the percentage of her body
    that is burned.

37
  • We will break her body into different geometric
    shapes. For example, her head will be a sphere,
    her arms and legs will be cylinders, her thorax
    will be a rectangular solid and her perineal area
    will be a triangle.

Alices areas
  • We will figure the surface area of each part of
    Alices body separately and then find the total
    by adding all the parts together.

55
Does Enhancing Math in CTE
  • Affect Technical Skill Development?

56
No difference in four sites experimental
students scored significantly higher in one site
57
Time invested in Math Enhancements
  • Average of 18.55 hours across all sites devoted
    to math enhanced lessons (not just math but math
    in the context of CTE)
  • Assume a 180 days in a school year one hour per
    class per day
  • Average CTE class time investment 10.3
  • Average total school time investment (assume 6
    classes per day) 1.7
  • Modest investment for major payoff


58
What we learned
  • When We Began the Study
  • A box of curriculum
  • Teacher training
  • Replicable by individual teachers
  • As a Result of the Study
  • A curriculum development process
  • Building and sustaining a community of practice
  • Replicable by teams of committed teachers working
    together over time
  • Core Principles

59
Replicating the Math-in-CTE ModelCore
Principles
  • Develop and sustain a community of practice
  • Begin with the CTE curriculum and not with the
    math curriculum
  • Understand math as essential workplace skill

60

61
Replicating the Math-in-CTE ModelCore
Principles
  • Maximize the math in CTE curricula
  • CTE teachers are teachers of math-in-CTE NOT
    math teachers

62
What we are and are not A contextual continuum
  • Traditional academic class (e.g. Algebra 1)
  • CTE Academic teachers coordinate around themes
    (e.g. health)
  • Occupation is the context for delivery of
    traditional academics
  • (Related or applied math)
  • Academics emerge from occupational content
  • Disconnected
  • Coordinated
  • Context Based
  • Contextual
  • Algebra 1
  • Academies
  • Integrated math
  • NRC Model

63
Issues
  • How much math can be enhanced in CTE before it is
    no longer a CTE class? (The tipping point
    issue) Crisis Immediacy we want a fix and we
    want it now
  • System investment (teacher time and PD costs)
    there is no cheap or quick fix
  • Should math credit be provided for enhanced CTE
    classes are we teaching math or providing a
    venue for students to learn how to use math?
  • 1. Highly qualified teacher
  • 2. Loss of CTE integrity

64
Conclusion The NRC Model
(Process)(Pedagogy)Mathachievement
Core Principles
65
Math-in-CTE
  • Making it happen
  • in your community

66
Necessary Ingredients
  • Communities of practice
  • 2. Administrator support
  • A. Professional Development (532) for at
    least one full year
  • B. Substitutes
  • C. PD support (facilities, etc.)
  • D. Staff the structure
  • 3. Document!!!

67
Core Principle A Develop and sustain a
community of practice
  • Cohorts of math-CTE teacher teams (10)are formed
    around specific occupational foci or CTE content
    (e.g. business, auto technology, health).
  • Communities of practice participate together in
    professional development several times during the
    academic year
  • External stimuli to help maintain focus

68
Core Principle BBegin with the CTE curriculum
and not with the math curriculum
  • Math-CTE teacher teams interrogate the
    curriculum, identifying the math that occurs
    creating curriculum maps that identify the
    intersection of occupational content and math
    constructs/concepts.
  • The CTE related math is mapped onto the
    curriculum using a scope and sequence

69
Teach the math when it occurs
  • "Placement of the lesson is an integral part of
    the students understanding the math concepts. I
    taught this lesson to two separate groups the
    group studying electrical circuits got "IT"
    immediately as a normal part of the CTE lessons.
    The group taught out of context had a much more
    difficult time with the lesson. When taught
    again "in" context, group two had a better
    understanding of the math application and its
    relevance."

70
Core Principle CUnderstand math as essential
workplace skill
  • Teacher teams generate math examples in which
    students solve authentic workplace problems.
  • Math is a tool used in the workplace.
  • CTE teachers bridge CTE and math vocabulary as
    they develop and teach the lessons.

71
Core Principle DMaximize the math in CTE
curricula
  • CTE teachers build on students prior math
    knowledge and skills.
  • Math-CTE teacher teams continue to locate as
    much math as possible in the CTE curricula
    throughout the school year.
  • CTE teachers capitalize on teachable moments that
    follow the math enhanced lessons.

72
Core Principle E CTE teachers are teachers of
math-in-CTE NOT math teachers
  • CTE teachers participate in professional
    development activities that enable them to teach
    the math as it occurs in their content.
  • CTE teachers learn more about the math concepts
    in their CTE curriculum.
  • CTE teachers learn math formulas and vocabulary.
  • CTE teachers are given opportunities to practice
    teaching the math in their curriculum.
