This study aims to investigate the effectiveness of using visual materials in teaching vocabulary to deaf students of EFL. For this purpose, 80 deaf students from a state special education vocational high school in Turkey contributed to this study. All students had first English classes in their lives and they are at the starter level of English, thus pre-test for their English proficiency was not given. The students were randomly divided into two groups to form the experimental group and the control group. 10 vocabulary items per week were taught to the students, and 50 target vocabulary items in total were taught during the whole study. To the experimental group, the vocabulary items were taught via visual materials together with the sign language. The control group was not presented with any visual items during the teaching process of the experiment, only sign language instruction was used for them. After the treatment, a vocabulary test was given to each group as an immediate post-test to measure the impact on learning. Six weeks after the immediate tests, delayed post-test was given to the groups to test long term retention. The results of the two post-tests were analyzed through Independent Samples t-test and Paired Samples t-test calculations to investigate the effectiveness of visual materials. According to the results of the study, visual materials were found to be more effective than using only the sign language that does not contain any visual items in teaching vocabulary items to deaf learners who learn English as a foreign language.

Purpose: Narrative medicine consists of the expression of medical experiences and the reflection on narratives to foster empathic communication with patients. Reflecting on narratives increases self-awareness and recognition of the feelings of the narrator or the story’s main character, which in turn affects the audience. This study was conducted to examine the impact of a narrative medicine program on the reflective capacity and empathy of medical students.Methods: A quasi-experimental study was performed during the 2018–2019 academic year at Isfahan University of Medical Sciences in Iran involving 135 medical interns in 2 groups (control [n=66] and experimental [n=69]). Interns in the experimental group took part in seven 2-hour reflective practice sessions, while those in the control group underwent no educational intervention. Pre-test and post-test assessments were conducted for both groups using 2 valid and reliable tools for the assessment of reflective capacity and empathy. Mean reflection and empathy scores were compared within groups (between pre- and post-test values) and between groups (using the paired-t test and the t-test; P≤0.05).Results: The mean reflection and empathy scores of the experimental group significantly increased from pre-test to post-test, but those of the control group did not. Moreover, the mean post-test scores were significantly different between the 2 groups (P<0.001).Conclusion: Narrative medicine is an effective teaching method that can improve reflective capacity and empathy, thereby ultimately promoting professionalism as a core competency in medicine. Consideration of learning conditions and interdisciplinary teaching are necessary for implementing a narrative medicine program.

This study examined the effect of Jigsaw technique as a part of cooperative learning on Iranian EFL learners’ reading comprehension. To this end, 40 intermediate participants were selected out of 73 EFL learners based on the results of Oxford Quick Placement Test (OQPT). The participants were divided into two groups; control and experimental. Then, the participants of both groups were pretested on reading comprehension. After pre-testing, the cooperative learning activities (Jigsaw technique) were practiced with the participants of the experimental group during 5 sessions. The experimental participants were assigned to five-member teams to work on reading texts. Each team member read an assigned section and then members from different teams who had studied the same sections met in ‘expert groups’ to discuss their sections. Then, students returned to their own teams and taught their team-mates about their section. On the other hand, the control group received traditional teacher-fronted instruction throughout the classroom time. After the treatment sessions, a teacher-made reading comprehension post-test was given to the participants of both groups to measure their reading comprehension ability after the treatment. The results of paired samples t-test and independent samples t-test revealed that the experimental group outperformed the control group on the post-test. The findings also showed that there was a significant difference between the post-tests of both groups in favor of the experimental group.

This study is aimed at finding out the effect of Collaborative Strategic Reading (CSR) on students’ achievement in reading comprehension on hortatory exposition text. Experimental design was applied in this research. The population was the 2014/2015 second year students (grade XI) of SMA Swasta YAPIM Medan. There were two paralel classes that consisted of 34 students. The total number of the population were 68 students. The total number of the sample were 68 students. The researcher selected the sample by using total sampling technique. The sample was divided into two groups, experimental group and control group. The experimental group was taught by using Collaborative Strategic Reading (CSR) strategy while the control group was taught without using Collaborative Strategic Reading (CSR) strategy. The data were taken by administering the pre-test and post-test to both control and experimental groups. These data were analyzed by using t-test. The result of computing the t-test obviously showed that t-observed (5.61) is higher than t-table (1.99) with the degree of freedom (df= 66) at the level significance 0.05. It means that the alternative hypothesis stating that there is a significant effect of Collaborative Strategic Reading (CSR) on students’ achievement in reading comprehension on hortatory exposition text is accepted.
