Summary

The United States has the highest incidence of teenage pregnancy in the industrialized world. Teenage pregnancy affects opportunities for education and preparation for the workforce especially for young women. Socioeconomic status and cultural backgrounds both impact attitudes toward and likelihood of teen pregnancy.

This social science module examines teenage pregnancy in the United States over time and by socio-demographic variables. Students will learn how to access and interpret Census data as well as begin to think sociologically about teen pregnancy patterns and risk factors.

Context for Use

This lab exercise designed for lower level undergraduates can be used in many sociology classes, most notably Introductory sociology, Social problems, Sociology of the Family, Basic Statistics and/or Research Methods. The exercise was created for an hour and fifteen minute lab period. Students must have access to the internet and should have a basic understanding of simple methodological concepts. The exercise can be completed once the chapter on methods in an Introductory textbook has been completed. The time needed for th module can be adapted be eliminating sections. The exercises build on each other, so it is piossible to only do 1-3 or divide across several class sessions.

Teaching Notes and Tips

I often do exercises of this type in pairs. The students seem less stressed and anxious because a partner may help.

Assessment

A pretest-posttest (see DataCounts for specific materials) will be administered to determine students' gains from the exercise. Competency through course grades will also indicate the effectiveness of this module.

This activity uses two customized data sets; one made from combining census information from 1950-2000 and one from the 1990 Census. It guides students through data manipulation using WebCHIP software found at DataCounts!.
