An Edublox program significantly improved the word recognition of students with reading difficulties over a period of 8 weeks (21 hours). Word recognition is the ability to recognize words at a glance. The Edublox group’s mean (n = 14) improved from 5.64 to 18.50, while the control group improved from 4.69 to 9.00 (n = 13). The maximum score is 20. The post-test mean difference between the two groups is 9.50 (Jatau et al., 2024, Journal of Human, Social and Political Science Research).

This means the Edublox group improved from 28% to 93%, and the control group from 23% to 45% on the word recognition test.  

The Edublox program also significantly improved the literal comprehension of these students. The Edublox group’s mean improved from 1.57 to 18.14, while the control group improved from 1.54 to 2.42. The maximum score is 20. The post-test mean difference between the two groups is 15.72 (Jatau et al., 2024, Journal of Education Research and Library Practice).

This means the Edublox group improved from 8% to 91%, and the control group from 8% to 12% on the comprehension test.  

The Edublox program significantly improved the spelling ability of these students as well. The Edublox group’s mean improved from 4.14 to 19.07, while the control group improved from 3.38 to 7.25. The maximum score is 20. The post-test mean difference between the two groups is 11.82 (Jatau et al., 2024, Sapientia Foundation Journal of Education, Sciences and Gender Studies).

This means the Edublox group improved from 21% to 95%, and the control group from 17% to 36% on the spelling test.
