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? After the application, the experimental group's geometry achievement test scores were significantly higher than the control group's (U=132.00, p<0.05). → Kesan 2013
Evidence¶
Kesan 2013¶
Kesan, C. & Çalıskan, S. (2013). The effect of learning geometry topics of 7th grade in primary education with dynamic Geometer's Sketchpad geometry software to success and retention. The Turkish Online Journal of Educational Technology, 12(1). https://eric.ed.gov/?id=EJ1008875
q2 · i? · causal · r2
Posttest-only control-group experiment with 21 experimental and 21 control 7th graders; Mann-Whitney U test on the Angles and Polygons achievement test. Means were 25.71 (experimental) versus 17.29 (control), and the article reports "a significant difference between the groups' scores".
"there is a significant difference between the groups' scores of achievement test prepared about the unit angles and polygons (U=132,00 , p<0,05). When the means are taken into consideration, it is seen that achievement scores of students in experimental group are higher than those in control group."
