Subclaims¶

q2 i? In the purposively sampled Chicago schools studied, students at both high and low prior achievement levels who received higher-quality assignments made greater-than-average gains; the comparison is observational, not a test of cause. → Wenzel 2002

q3 i? Students with both high and low prior achievement benefit from intellectually demanding assignments, with high-achieving students benefiting more in reading and low-achieving students benefiting more in mathematics. → Smylie 2006

Evidence¶

Wenzel 2002¶

Wenzel, S., Nagaoka, J., Morris, L., Billings, S., & Fendt, C. (2002). Documentation of the 1996-2002 Chicago Annenberg Research Project Strand on Authentic Intellectual Demand Exhibited in Assignments and Student Work: A Technical Process Manual. Consortium on Chicago School Research. https://consortium.uchicago.edu/publications/documentation-1996-2002-chicago-annenberg-research-project-authentic-intellectual

q2 · i? · associational · r2

The manual summarizes this finding from the Newmann, Bryk, and Nagaoka (2001) report, printing that "Both students with high and low prior achievement levels benefit from being exposed to high quality assignments." The manual notes that its schools were sampled purposively and the findings "cannot be used to generalize to all Chicago public schools"; the finding is an observational association between assignment quality and achievement gains, not a randomized or quasi-experimental test. No effect size is given here.

"Both students with high and low prior achievement levels benefit from being exposed to high quality assignments."

Smylie 2006¶

q3 · i? · theoretical · r2

Newmann, Bryk, and Nagaoka examined how prior achievement related to benefits of demanding assignments. They found "students who received assignments that were relatively more intellectually demanding out-performed comparable students who received less demanding assignments" across prior-achievement levels.

"Regardless of levels of prior achievement, students who received assignments that were relatively more intellectually demanding out-performed comparable students who received less demanding assignments."

Discussion¶

Learner Variables¶

• Prior Knowledge — moderator: an instructional effect differs with it

Related Claims¶

• Both high- and low-prior-achieving students benefited from high-quality assignments, with math favoring low achievers and reading favoring high achievers — a narrower finding that bears on this claim
• Chicago classrooms with high-quality authentic intellectual assignments showed greater one-year ITBS gains than classrooms with low-quality assignments — related
• Exposure to high-quality assignments predicted substantially higher IGAP reading, mathematics, and writing performance (effect sizes 0.43, 0.64, 0.52) — related
• The report cites research evidence that students exposed to authentic intellectual challenges are more engaged than students given conventional schoolwork — related
• Peer-assisted learning interventions improve achievement for elementary students — related
• Intellectually Ambitious Instruction Is Associated with Improved Student Learning Across Populations — a broader claim this one bears on
• A 1998 baseline study found typical Chicago assignments were mostly rudimentary basic-skills exercises, but most students completed the more demanding tasks they were given — related
