The present study aims to evaluate the single-case experimental studies on teaching math skills to individuals with
autism spectrum disorders in terms of (a) quality indicators developed by Horner et al. (2005), (b) descriptive
analysis of the variables used in these studies, and (c) effect sizes of the interventions to decide whether they are
evidence-based. Various databased were searched and the analyses were conducted for 26 studies. Results showed
that 10 research studies classified as “acceptable” in terms of meeting quality indicators developed by Horner et
al. (2005). The effect sizes of tese studies were calculated (Tau-U and PND) and results showed that visual
presentation instructions and strategy-based instructions are the promising instructions in teaching math skills to
individuals with autism. Based on the findings, future research needs and recommendations to the practitioners are
discussed.

Otizm Spektrum Bozukluğu Olan Bireylere Matematik Becerilerini Öğretimi: Tek-Denekli Araştırmalarda Betimsel ve Meta Analiz

Öz

Bu çalışmanın amacı otizm spektrum bozukluğu olan bireylere matematik becerilerinin öğretimini hedefleyen tekdenekli deneysel çalışmaları; (a) Horner ve diğerlerinin 2005 yılında geliştirdikleri “Tek-denekli Deneysel
Araştırmaların Niteliksel Göstergeleri” yönergesi açısından değerlendirmek, (b) kapsamlı betimsel analizlerini
gerçekleştirmek ve (c) etki büyüklüklerinin hesaplanarak bu uygulamaların bilimsel dayanaklı uygulamalar olup
olmadıklarını değerlendirmektir. Bu kapsamında çeşitli veri tabanları taranarak elde edilen 26 çalışmanın analizleri
gerçekleştirilmiştir. Bulgular, 10 çalışmanın Horner ve diğerleri tarafından önerilen niteliksel göstergeler
kapsamında “kabul edilebilir” düzeyde olduğu yönündedir. “Kabul edilebilir” düzeyde değerlendirilen
çalışmaların etki büyüklükleri elde edilmiş ve görsel sunum temelli ve strateji temelli uygulamaların otizmli
bireylere çeşitli matematik becerilerinin öğretiminde umut vaat eden uygulamalar olduğu görülmüştür. Elde edilen
bilgiler alanyazın dikkate alınarak tartışılmış ve uygulamacılara ve araştırmacılara yönelik birtakım önerilerde
bulunulmuştur.
