Walberg, Herbert J.; Tsai, Shiow-ling – Journal of Educational Psychology, 1984
To probe the association of reading achievement with factors in learning, the scores of 2,890 13-year-old students from a National Assessment of Educational Progress sample were regressed on 24 indexes of the factors, singly and as a set. Achievement showed diminishing or eventually negative returns to eight time variables. (Author/BS)
