Subclaims¶

q2 i? Heavy boys developing early, average boys developing at medium periods, and light boys developing late rank well in scholarship in eight cases and poor in three; heavy-late and light-early-or-medium boys rank well in no case and poor in four. → Stewart 1917 q2 i? For height, tall boys increasing rapidly at early or medium periods and average boys at medium periods do good work in six cases and poor in three; short boys of medium or late period do well in one case and poorly in six. → Stewart 1917 (2)

Evidence¶

Stewart 1917¶

Stewart, S. F. (1917). A study of physical growth and school standing of boys. The Journal of Educational Psychology. https://doi.org/10.1037/h0070804

q2 · i? · associational · r1

Chart XII classifies the twenty-nine boys by weight at fourteen years and period of most rapid weight increase against scholarship standing. The complementary group is described: heavy boys developing late and light boys developing early or medium "rank well in no case and poor in four cases."

"Heavy boys who develop early, average boys who develop at medium periods, and light boys who develop late, rank well in scholarship in eight cases and poor in three cases."

q2 · i? · associational · r1

Chart XIII classifies the same boys by height at fourteen and period of rapid height increase. Short boys of medium or late period do well in one case and poorly in six; boys with indefinite rapid-growth periods do well in four cases and average in one.

"Tall boys who increase rapidly at early or medium periods and average boys who increase rapidly at medium periods are doing good work in six cases and poor work in three cases."

Discussion¶

Related Claims¶

• Tall, heavy children with good lung capacity are further along toward mental maturity as evidenced by school progress, based on 21,682 final term grades — a broader claim this one bears on
• When individual growth-increment curves are correlated with scholarship without reference to body size or stage of development, no decided relation between scholarship and physical growth appears — related
• In a same-age, same-class group of eight boys followed through high school, the higher-scholarship half averaged taller in all four years and heavier in all years except the junior year — related
• Group averages suggest a positive relation between weight and scholarship in the elementary grades, but the relation in high school is uncertain — related
• Most high-school students made rapid or normal elementary progress, yet most fail in some high-school work, and schools appear better fitted for girls than for boys — related
