Pass rate of Experiment group (MathXL online homework and multiple tutors) was 31%; Control-1 group (MathXL homework and single tutor) 38%; Control-2 group (paper homework and single tutor) 43%. Thanks to Alice Cunningham for providing me with the full paper.Deltahttps://www.blogger.com/profile/00705402326320853684noreply@blogger.comtag:blogger.com,1999:blog-7718462793516968883.post-38207951880331434372012-06-08T21:17:10.668-04:002012-06-08T21:17:10.668-04:00Follow-up: The tremendous positive results shown a...Follow-up: The tremendous positive results shown at Hostos were in fact only for Arithmetic. There was no statistically significant effect shown for Algebra.Deltahttps://www.blogger.com/profile/00705402326320853684noreply@blogger.com
