The purpose of this study was to compare the effectiveness of two kinds of reinforcements, tangible reinforcements and social reinforcements, on the academic achievement of eighth-grade female students with intellectual disabilities in the science subject. The study was an experimental method by pretest, with a control group. The participants of the study comprised 45 female students with intellectual disabilities from three different middle schools in the province of Tehran. The multistage cluster method was chosen to determine the sample. The Wechsler intelligence test for matching the groups in terms of IQ and teacher-applied tests were used for all students to measure the progress of students in science. Data were analyzed by one-way analysis of variance. The results showed that (a) there was a significant difference in the academic achievement scores of the groups after applying the intervention and (b) the mean difference in achievement scores for the tangible reinforcements group was significantly higher than the social reinforcement group and the control group. Also the mean scores for the social reinforcement group were significantly higher than the control group.

Adolescents with hearing loss have been shown to have some emotional difficulties. This study investigated the effectiveness of a resilience training program on the emotional intelligence of mainstreamed adolescent students with hearing loss. In this experimental study, a pre-test, post-test, follow up and control group design was implemented. After receiving informed consents, 122 students with hearing loss in mainstreaming settings were randomly assigned to intervention and control groups (61 students in interventional group and 61 in control). The interventional group received training in groups of 3 to 5, for 6 weeks (two times per week for 75 min). The intervention focused on feelings, thinking (positive, negative) and outcomes of negative thinking, coping strategies, strengths and weakness, problem solving, communication skills, social skills, negotiation, despising and ridiculing, intra- and interpersonal skills. The Connor-Davidson resilience scale (CD-RISC) and the Schutte Emotional Intelligence Scale were used to measure the resilience and the emotional intelligence (EI) of participants respectively just before intervention, as well as at the 6- and 14-week marks. The Friedman Test was used to compare changes in emotional intelligence between interventional and control groups. The intervention increased the resilience scores by 20 points. Although the EI of both groups were similar at the beginning of the research, there was a significant difference between the control and interventional groups in emotional intelligence and its aspects after intervention, at the 6-week and 14-week measurements (p < 0.001). The effect size was 1.5 for the EI total score. The 6-week resilience training program was very effective at improving emotional intelligence and could be readily used to help students with hearing loss improve their emotional abilities.
