[Systematic application of visualized solution algorithms and verbal self-instruction in spelling remediation: initial results of general practice outcomes].
In this study the effects of a remedial spelling training approach were evaluated, which systematically combines certain visualization and verbalization methods to foster students' spelling knowledge and strategy use. Achievement-related pre- and posttest data of two treatment cohorts including children and adolescents with severe spelling disabilities were analyzed. The treatment was administered in single-case or small group sessions and took about 85 hours in average. In each cohort empirical results could demonstrate statistically significant increases in students' spelling test performance.
