The relationship between oral expression, gesture and sign language in objectification of mathematical concepts; hard of hearing student example

Abstract In the literature, most studies consider the relationship between oral expression, gesture, and sign language for hearing students. In the present study, it was investigated how the modality was used by hard-of-hearing and deaf students to process of objectification of the “angle” concepts in teaching and learning situations. The study is based on a phenomenology model in qualitative research methods. The semiotic bundle approach were utilized to analyze the relevant data. The semiotic bundle allowed us to focus on the relationships of sign and gesture with other semiotic resources within a multimodal approach in the literature. The study showed that gestures accompanying sign language were used to objectify the concept. Based on the finding that sign (SL or gesture) is very important for students with hearing difficulties, studies can be conducted on sign language and gestures in students with hearing difficulties in different subjects of mathematics.
