Answer:
Cross-sectional- within a short period of time test several groups, each at a different age,
of home schooled children on a measure of social development. The pro is less time
involved and the con is cohort effect.
Longitudinal- begin with a group of 5-6 year olds who are to be home schooled and
retest this group periodically, over a 10-12 year period. The pro is avoiding the cohort
effect, the con is cost and length of the study.
Sequential- test several groups of different age children at one time, then retest each
group on a measure of social development over a period of time. This method combines
the pros of the other two and avoids some of the cons.
