The purpose of this study is to investigate the size effect by meta-analysis considering studies on learning strategies of learning disabilities.
In order to achieve the purpose, the following questions were formulated:
First, to what effect does learning strategies influence learning disabilities?
Second, to what effect do cognitive strategies, reading strategies, mathematics strategies and other learning strategies influence learning disabilities?
Third, to what effect do reading, writing, mathematical problem solving, learning achievement, affective and cognitive ability influence learning disabilities?
Fourth, to what effect does each area applied by each learning strategy?
For such studies, we have used meta-analysis to measure the effect. The basic formula for such analysis is as follows:
We divide the difference between the mean score of the experiment group and that of the control group by the standard deviation.
The finding can be summarized as follows:
First, the meta-analysis result on the effect of all learning strategies of learning disabilities is 1.1266. This is a big effect. This means that if we set the control group at 50%, then there is a 37% improvement.
Second, the meta-analysis result on the specific learning strategies with the learning disabilities from highest to lowest is mathematical: (1.4440), other learning: (1.2808), reading: (1.2079) and cognitive: (0.8481).
Third, the meta-analysis result on each applied area to the learning disabilities from highest to lowest is writing, learning achievement, mathematical problem solving, cognitive, reading and affective ability.
Fourth, the meta-analysis result on the effect of each area applied by each learning strategy shows the overall effect.
