q2 · i? · causal · r1

Pre-and-posttest tabulation of the eleven-student inquiry project: pretest scores were zero for every student, and the article reports "89% of the students knew four or all five of the taught sight words" for both groups combined. Descriptive percentages only; no test statistics are printed.

"Posttest scores indicated growth in sight word acquisition as all students knew at least three or more sight vocabulary words on the posttest."

Related Claims¶

• ELL first graders who learned ASL signs with sight vocabulary moved from zero pretest words to perfect posttest scores — a narrower finding that bears on this claim
• First graders taught sight words with ASL signs achieved higher posttest accuracy than students taught without ASL — related
