This paper examines outcomes and student efforts devoted to educationally p
urposeful activities at different points. While substantial proportions of
students make noteworthy progress in intellectual and communication skills,
personal and social development, and vocational training, declines occurre
d in literature, arts, science, and values development. One explanation for
the declines is that students on average expend less effort in many areas
since the mid-1980s, even though they are getting higher grades.
