Examining Turkish Graduate Theses on Mathematics Education for Hearing Impaired Individuals

Abstract

The aim of this research was to conduct a systematic review to examine the theses written in Türkiye on mathematics education among individuals with hearing impairment. Studies were identified through searches of the electronic database of the Higher Education Council Publication and Documentation Department Thesis Center. Theses were the full text of which can be accessed until 30 September 2022. The inclusion criteria were met by 9 theses. In this research, theses were classified in terms of aim, study design, the sample definition of hearing impairment, the main results, and recommendations related to the learning and teaching process of mathematics education. The studies primarily focused on the impacts, due diligence, relationship identification, and perspectives concerning the teaching of mathematics to students with hearing impairments. A wide range of teaching methods, tools, activities, and resources were found to influence learning outcomes. The analysis of the theses underscored the significance of factors beyond hearing loss, such as teaching methods, students' experiences, and the ability to connect mathematical concepts to real-life situations. Sign language and gestures emerged as crucial for mathematics education. Despite some highlighted challenges in problem-solving and geometry performance, a plethora of recommendations was provided to enhance mathematics instruction for students with hearing impairments, ranging from classroom utilization to supporting and evaluating students. This comprehensive review underscores the need for diversified and tailored strategies to enhance mathematics education for students with hearing impairments.
