Sally Simple works
at a local elementary school that has implemented a new reading
program that requires 100 additional hours of language exercises
each academic year for all grade levels. A recent study by educational
psychologists indicated that language exercises encouraged students
to read more books and helped them remember what they read.
Sally randomly samples 200 teachers and parents. She asks, "Is
the new language program improving the reading skills of your
children?" The survey responses were:
1. Has Sally defined
the problem?
2. Does Sally know
what to study regarding the new program and how to study it?
3. Is Sally's behavior
ethical?
4. In what ways has
Sally contributed and/or failed to contribute to our understanding?
5. What research design
has Sally used?
6. Are there alternative
plausible explanations for the perception by 80% of those surveyed
that said the new language program improved the reading skills
of their children?
7. Did the new language
program cause a change in reading skills?
8. What does Sally
actually know based on her study?
