parenting skills and psychological adjustment are similar to heterosexual parents
Child Abuse
delays in cognitive dev. reduced school performance
less friend > relationship problems
Aggresisive and other behavior problems.

Children of abuse are premature, low birthweight, difficult temperament, poor health higher risk if < 3.
Self-fulfilling Prophesy Effect
teachers respond differently to gender
Boys-corrected, criticized-praised-helped
Head start
initial academic gains lost
better attitude about school
Cooperative Learning
improves performance /self-esteem-enhances cross-racial relationships
Beneficial for high-performing students
helpls low achieving students
Allows children to work at own pace
improves achievement tests
and attitudes toward subjects
beneficial for low-functioning and special need children
Males >engaged
1/3 waking time in front of TV
increases aggeression and toleranace for aggression
Read less, poorer school performance
