Subclaims¶

q3 i3 Intervention teachers were observed using the DCCS instructional strategies far more than control teachers (Hedge's g = 2.02). → Leslie M. Babinski 2018 q3 i3 Intervention teachers also used Adapted Strategies more than control teachers (Hedge's g = 0.95). → Leslie M. Babinski 2018 q3 i? No differences were found between groups on CQELL Generic Lesson Elements or EL Support, indicating similar overall instructional quality. → Leslie M. Babinski 2018

q3 · i3 · causal · r2

Intent-to-treat analysis of aggregated ratings from three classroom observations per teacher using the CQELL and the researcher-created DCCS Observation Tool, comparing 14 intervention and 16 control teachers. The article reports "Hedge's g = 2.02" for DCCS Strategies and g = 0.95 for Adapted Strategies; no group differences on Generic Lesson Elements or EL Support.

"However, the intervention did lead to greater use of Adapted Strategies ( Mdiff = 0.57, 95% CI [.05, 1.10], p =.032, Hedge's g = 0.95) and DCCS Strategies ( Mdiff = 0.38, 95% CI [0.27, 0.50],p .001, Hedge'sg = 2.02) relative to teachers in the control group."

Related Claims¶

• Students whose teachers participated in the DCCS program showed greater gains than control students on the Story Recall and Verbal Analogies subtests of the WMLS-R — related
• Students with lower initial English proficiency benefited most from their teachers' participation in the DCCS program, while students above the 5th percentile showed no differential benefit — related
• The DCCS professional development program increased teachers' use of the targeted high-impact instructional strategies relative to control teachers — possibly the same claim (merge candidate)
• The intervention did not change overall classroom instructional quality as measured by the CQELL Generic Lesson Elements and EL Support subscales — related
