  1. TEACHING DATA STRUCTURES AND RELATIONSHIPS USING THE GENERAL SOCIAL SURVEYS Stephen Sweet Ithaca College Professional Enhancement Programs Conference Macalester College June 17, 2005

  2. What Can a Unicorn and a Carpenter Tell Us About Math and Quantitative Literacy?

  3. “Real” Mathematics Geometry Algebra Trigonometry Calculus Focus is on math as a purpose unto itself. Principles to be studied, dismantled, and synthesized. Absolute precision is expected Quantitative Literacy The blending of mathematical tools with linguistic constructs Focus is on the application of mathematical reasoning to consider the workings of the natural and social worlds Math-Lite? Pragmatic orientation to imprecision Greater acceptance mathematical blackboxes The Two MathematicsSource: Madison, Bernard. 2004. “Two Mathematics: Ever the Twain Shall Meet? Peer Review 6:9-12.

  4. Structure a lab situation that opens opportunities for questioning and exploring data. As part of the experience, students engage in critical reasoning through dialogue. Process Introduce data Form hypotheses Test hypotheses with bivariate methods Critically reflect on findings through dialogue and form new hypotheses Test these relationships with bivariate and multivariate methods A Deweyian Approach to Quantitative LiteracyDewey, J. (1916). Democracy and education. New York: Macmillan.

  5. Annual surveys conducted by the National Opinion Research Center The first survey took place in 1972 and most recent survey was in 2002. Some questions have been asked in all surveys, other questions have been introduced as “modules.” Strong emphasis on reliability across years. Since its inception more than 38,000 respondents have answered over 3,260 different questions. Enables longitudinal analyses and the study of change over a thirty year span Enables comparisons of subgroups from a representative sample of American adults By combining data across years, the GSS enables the identification of subgroups in the population, even those that are usually with too few number to be studied in other surveys (e.g. retirees, homosexuals, members of minority religions, etc.) The General Social Surveys (GSS)

  7. Take 4-5 minutes to perform a subject search to find a topic of interest. Examine the variables, question phrasings, and data structures. Pick one or two dependent variables that you would be interested in examining.

  8. Take 2 minutes to perform a frequency on your variable of interest. Is there anything interesting that you observe in the distribution?

  9. Why Is No Relationship Observed? • Perhaps there is no relationship! • Perhaps we need to reconstruct the measure of TV viewing, not as a continuous measure, but rather as a concern of “heavy” and “light” watching. • Perhaps individual years do not give us sufficient sample sizes to detect trends. • Let us try recoding variables and changing data structures and see if that changes our conclusion

  10. Examine Trends • Everyone take 10 minutes to see if your variable of interest shows any relationship the variable YEAR (the date in which the respondent took the survey). You may want to recode your data if it is continuous, and possibly restructure the variable YEAR. If you do not have multiple years represented, you may want to select another variable to explore. If time allows, explore longitudinal relationships with other variables in your subject area.

  11. Comparing Subgroups in the Population • Sex • Race • Income • Age • Political Orientation • Religiosity • Sexual orientation • etc

  12. Is race/ethnicity associated with television viewing?

  13. Take 5 minutes and test your variable against the variable RACE. If time allows, explore other relationships.

  14. Why do African Americans watch more TV? Can we test this with multivariate methods?

  15. Take 5 minutes and introduce a control variable into your analysis, or test a relationship that someone else reported that you believe may be spurious.

  16. A Deweyian approach to quantitative literacy Engages students in the construction of questions Challenges students to generate answers to their own questions From this approach, students learn both skills and the value of quantitative literacy. Conclusion and Discussion Discussion – What are the concerns of using such an approach in the context of mathematics courses, or as the QL standard for a bachelor’s degree?
