Abstract

This study aims to investigate the learning processes involved in constructing a coordinate system with a learning trajectory by a student with visual impairment. The study is a teaching experiment designed according to the concrete material-supported hypothetical learning trajectory. The teaching experiment was conducted through clinical interviews with a student with visual impairment for the determination of pre-knowledge, construction of the number line and construction of the coordinate system. The data obtained from the video recordings of the sessions were analysed through ongoing and retrospective analysis. Despite containing visual elements and having learning outcomes different from those in the curriculum, it was discovered at the end of the teaching sessions that a student with visual impairment was able to identify the origin, coordinate axes using a fixed reference unit, determine ordered pairs in the coordinate system, and represent them symbolically. Although the hypothetical learning trajectory's objectives varied in sequence, it was determined that the concrete materials used served the purpose of the activities and allowed students to develop strategies. Thus, the results were presented as a guide for designing curricula, individualized education plans, and educational support materials.

Görme Yetersizliğinden Etkilenen Bir Öğrenciyle Koordinat Sisteminin İnşasına İlişkin Bir Öğretim Deneyi

Abstract

Bu araştırmada görme yetersizliğinden etkilenen bir öğrencinin koordinat sisteminin inşasına dair öğrenme süreçlerinin öğrenme yol haritasıyla incelenmesi amaçlanmaktadır. Araştırma somut materyal destekli tahmini öğrenme yol haritasına göre tasarlanan bir öğretim deneyidir. Öğretim deneyi, görme yetersizliğinden etkilenen bir öğrenciyle ön bilgilerin belirlenmesi, sayı doğrusunun inşası ve koordinat sisteminin inşası için yürütülen klinik görüşmelerle gerçekleştirilmiştir. Video kayıtlarından elde edilen veriler süregelen ve geriye dönük analiz yoluyla analiz edilmiştir. Görsel unsurlar içermesine ve öğretim programındaki kazanımlardan farklı hedefler üzerine inşa edilmesine rağmen, öğretim oturumları sonunda görme yetersizliğinden etkilenen öğrencinin orijini belirleyebildiği, başlangıç noktasını referans alarak sabit bir birimle eksenleri koordinatlandırabildiği, sıralı ikilileri koordinat sisteminde belirleyebildiği ve sembolik olarak temsil edebildiği ortaya konulmuştur. Tahmini öğrenme yol haritası hedeflerinin diziliminde farklılık olsa da yararlanılan somut materyallerin etkinliklerin amacına hizmet ettiği ve öğrencilerin stratejiler geliştirmesine fırsat verdiği tespit edilmiştir. Böylece, tasarlanacak olan öğretim programları, bireyselleştirilmiş eğitim programları ve destek eğitim materyalleri için kılavuz niteliğinde sonuçlar sunulmuştur.
