New Perspectives in Science Education

Hearing one of the top human senses. Hearing loss is the third most common disability in Iran and its prevalence among infants in every 1,000 babies is 7.4. The World Federation of the Deaf (WFD) promotes and safeguards the right of all Deaf people to quality education, starting at birth and throughout life. As for all learners, Deaf children have the same right to education and full access to quality education. The early years of life, a very sensitive period in which the attitudes, values and skills needed to maintain and support the environment are formed. Educational Justice order that deaf children are not deprived of receive environmental education. Furthermore,  some  researchers  have  shown  that multimedia can increase students' motivation and improve their learning attitudes. Chang, Chen, and Hsu (2011)  also  suggest  that  although  improving  and  promoting  environmental  knowledge,  attitude,  and behaviour  i s a common goal, different teaching or training methods are applied in different places. The purpose of this study was to investigate the effects of computer games on environmental education to the deaf children's. Due  to  its  object  and  purpose  of  the  study  was quasi-experimental.  To  achieve  the  research objectives,  pretest  and  posttest  design  with  control

and  experimental  groups  have  been  taken.  The  study  population  included  all  the children are deaf in Tehran. By available sampling 12 deaf students in Tehran were selected and to help coaches In both groups (control and test) were exposed. In the first session of the content of the course, the pre-test was held. Then, the researcher to design learning activities related to environmental concepts, coach children with educational computer games made after the end of seven sessions, the participants were assessed. Findings of the information was obtained through interviews Validity and reliability provided by 15 experts and Cronbach's alpha coefficient was calculated 92/0.

Data were collected, which is calculated after determining the validity and reliability (92/0) was conducted. Data were analyzed using descriptive and inferential statistics. The results from the questionnaires showed that the level of significance for changing the knowledge, attitudes and behavior of environmentalists smaller than / 05 is obtained. As a result, the study's assumptions on the effectiveness of computer games environmental education to be confirmed. Computer games are effective in teaching and learning environment for deaf children. These research results Sung Chang (2007), praise (2011), and Bdsv Meyer (2011), Amini oven, Saleh Sedghpour and Hossein Zadeh (2012) Dolf Chrsh (2011), and pour prosper and Marashi (2012 ), Amory (2010), Cheng-Peng Chao (2010), Ptkv and Rvzgrz (2011), and Kvasyych, Mynvvych, Milo Vanvych, Pablvs and Astarkvych (2012), co-ordinated and all have concluded that the games Computer training role in teaching and learning.
