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? Of 31 studies reviewed by the WWC, only one (Torgesen et al., 2001, a randomized controlled trial with 50 students in the analysis sample) met WWC evidence standards; the remaining 30 did not meet standards or eligibility screens. → What Works Clearinghouse 2010
Evidence¶
What Works Clearinghouse 2010¶
What Works Clearinghouse, U.S. Department of Education. (2010). What Works Clearinghouse Intervention Report: Lindamood Phoneme Sequencing® (LiPS®). Students with Learning Disabilities. https://ies.ed.gov/ncee/wwc/InterventionReport/279
q2 · i? · review · r3
WWC review of the LiPS evidence base for students with learning disabilities. Thirty studies were excluded for reasons including no comparison group, samples with less than 50% students with learning disabilities, or non-primary analyses; the report states the extent of evidence is "small" in all five domains examined.
"Thirty-one studies reviewed by the WWC investigated the effects of LiPS® on students with learning disabilities. One study (Torgesen et al., 2001) is a randomized controlled trial that meets WWC evidence standards."
