Very little research has been conducted to determine whether instructi
onal practices experienced by young adolescents have lasting effects t
hat can be connected to persistence in the study of science years late
r. The current study examined the question of whether variables associ
ated with middle school classroom practices and instructional emphasis
would contribute to a prediction of science course placement in the 1
1th grade. A LISREL analysis was performed to create a model that ties
middle school classroom experiences to later course placement. Variab
les associated with a holistic approach to science and with clarity of
presentation were retained in the final model.
