Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Only one study of Headsprout Early Reading met WWC evidence standards, so the extent of evidence is small and the effectiveness rating is potentially positive rather than positive. → What Works Clearinghouse 2009
Evidence¶
What Works Clearinghouse 2009¶
What Works Clearinghouse, U.S. Department of Education. (2009). Headsprout® Early Reading (WWC Intervention Report). https://ies.ed.gov/ncee/wwc/InterventionReport/211
q2 · i? · review · r3
WWC review of 13 identified studies: one RCT met standards; 11 did not meet standards or eligibility screens; one single-subject design could not be reviewed. The positive-effects rating criterion requiring two or more studies was explicitly not met because only one study met evidence standards.
"One study of Headsprout ® Early Reading meets What Works Clearinghouse (WWC) evidence standards and no studies meet WWC evidence standards with reservations."
