Scruggs, Marie M. – Science and Children, 1988
Reviews recent research addressing the problem of matching students' cognitive levels to science textbooks. Suggests that most texts are written above the level of the students for whom they are written. Promotes experiential learning at the middle level and concentration on "right thinking" rather than on "right answers." (CW)
