Presentation Transcript
service vs mainstream
Service vs Mainstream?
  • A troublesome dichotomy!
    • “mainstream” students need to understand applications
    • “service” students need authentic learning they can use
  • First Course vs Higher Level Course
    • same approach at each level – conceptual understanding

(more, not different, for higher level)

    • not merely the level of mathematics
what is wrong with traditional approach
What is wrong with traditional approach?

Is there any evidence that a major change is needed?

Descriptive stats, sampling, estimation,

hypothesis testing, regression …

evidence for needed change
Evidence for needed change?
  • growth of applied-statistical disciplines: biostatistics, psychometrics, envirometrics, official statistics, …
  • lack of job ads for “Statistician”
  • low enrolments in statistics of undergraduate majors and graduate programs
  • high proportion of students taking the minimum required courses in statistics
  • rarity of departments of statistics
  • low status among stat faculty of “applied” work
change of approach needed
Change of Approach Needed
  • E2L2
  • Experience Early, Logic Later
  • Case studies – techniques as required, thenlogical structure to link ideas (Math & Logic)
strategies for a first course
Strategies for a first Course
  • Avoidance of a technique-oriented textbook
  • Experiential presentation of techniques in areas of interest
  • Use of computing by instructor for simulation and graphics
  • No student computing, few formulas
  • Open book & notes for tests and exams
  • Use of graphics for explanations
  • Require verbalization of why, what, when
  • Sample tests and exams to impart objectives
  • Application material that is an important part of a general education
  • List of Concepts, Contexts and Techniques as an aid to exam preparation

sequence of case studies
Sequence of Case Studies

for example

  • stock market index
  • sports leagues
  • Olympics medals
  • fuel consumption annual pattern
  • casualty insurance
  • city populations
  • lotteries
  • spam filters

Many basic concepts and techniques are needed for such cases

simulations with graphics
Simulations with Graphics
  • sampling dist’n of the sample mean
    • insurance company survival
    • diversification of investments
  • illusions of randomness
    • sports leagues
    • spatial clustering of plants
technique coverage by example
Technique Coverage by Example
  • sampling error
    • forensic science example
    • randomized response example
  • regression
    • spam filter
    • electronic marketing example
  • estimation
    • Africanized bee invasion
    • political polls
verbalization
Verbalization
  • need to have students explain concepts with words
  • tests and exams that require this skill
  • integrate general intelligence with stats concepts
tests and exams open book
Tests and Exams – Open Book
  • discourage memory work without understanding
  • focus attention on concepts and problem-solving
  • make assessment more authentic to real-life needs
strategies for a higher level
Strategies for a Higher Level?
  • Avoidance of a technique-oriented textbook
  • Experiential presentation of techniques in areas of interest
  • Use of computing by instructor for simulation and graphics
  • No student computing, few formulas
  • Open book & notes for tests and exams
  • Use of graphics for explanations
  • Require verbalization of why, what, when
  • Sample tests and exams to impart objectives
  • Application material that is an important part of a general education
  • List of Concepts, Contexts and Techniques as an aid to exam preparation
  • Math as a simplification technique, to summarize technique structure
