The Effectiveness of a Training Program Based on Multimedia on Enhancing the Teaching Process and Critical Thinking Skills of Teachers of the Deaf and Hearing-impaired in Secondary Schools

The main aim of the current study is to measure the effectiveness of a training program on enhancing the teaching process and critical thinking skills among teachers of the deaf and hearing-impaired in secondary schools through multimedia and according to academic qualification and years of experience variables. To accomplish the study objective, the researchers used the quasi-experimental approach. They designed a four-hour short training program that was applied to 60 teachers of the deaf and hearing-impaired in secondary schools. The study findings revealed that 53.4% of teachers of the deaf and hearing-impaired possess multimedia skills experience in teaching critical thinking skills in the pre-test, whereas 61.3% of teachers of the deaf and hearing-impaired possess multimedia skills experience in teaching critical thinking skills in the post-test. In addition, the results showed no statistically significant differences in the years of experience variable in teaching critical thinking skills. Furthermore, the results indicated that the teachers who have Master's degrees or higher had higher average scores in critical thinking skills compared to those with bachelor's degrees.
