Entwicklung von Unterrichtsmaterial zum Uhrenlernen und erste Evaluation im Multiple Baseline Design

Es wurden didaktische Materialien zur Verbesserung des Uhrlesens und des Zeitverständnisses entwickelt und in einem MBD mit sechs Teilnehmerinnen evaluiert. Insgesamt bestätigt sich das große Potential der modularen Materialreihe. Sie sind frei als Open Educational Resource frei verfügbar.

Single Case Design Research als Methode evidenzbasierter Sprachförderung und -therapie

Der Beitrag stellt die Idee hinter kontrollierten Einzelfallexperimenten beziehungsweise Single Case Research Designs (auch Single Case Experimental Designs) vor und arbeitet ihr Potential im Kontext evidenzbasierter Sprachtherapie und …

Statistical Power of Piecewise Regression Analyses of Single-Case Experimental Studies Addressing Behavior Problems

We conducted a Monte-Carlo study to investigate the influence of single-case research design chracteristics (phase length, initial DV level, intervention effect, trend) on the test power of piecewise Poisson-regression models. PLM have a high potential of adequately identifying intervention effects in single-case research designs. However, few measurement times, especially in phase A, and low initial DV levels make it impossible to detect even large intervention effects. Research designs with a high number of measurement times show robust power.

Validity and Judgment Bias in Visual Analysis of Single-Case Data

We had 186 pre-service teachers visually analyze single-case graphs, representing an intervention effect, a baseline trend, both, or no change at all. The presence of a baseline trend increased type I errors from 5% to 25%. Inter- and intra-rater reliabilities were low, particularly for graphs including a baseline trend.

Efficacy of a working memory sensitive math intervention for primary school children

Interventions to support children with mathematical learning difficulties typically address deficits in domain-specific knowledge. However, not all students benefit from these instructional programs. In this case, some authors suggest an even more …
