The present study aimed to compare the effects of physical, cognitive and combined rehabilitation on improving working memory and cognitive flexibility of the elderly living in the nursing home. This quasi-experimental study was carried out with a pretest-posttest design in four groups with the control group. The statistical population consisted of all elderly residents of a nursing home in Tehran. 48 people were selected randomly and divided into four groups (three experimental groups and one control group). For the experimental groups, intervention programs, including physical, cognitive, and combined rehabilitation, were conducted in three sessions of one hour each week for two months. The data were collected using a working memory capacity scale and a cognitive flexibility inventory (CFI). Data was analyzed using a one-way analysis of covariance (ANCOVA) and Bonferroni post hoc test using SPSS software version 22. The results showed that all three types of rehabilitation programs have a significant effect on improving the working memory and cognitive flexibility of the elderly (P <0.001). Also, the mean of the groups in the pre-test and post-test stages showed that among the three programs, the combined rehabilitation program had more efficacy in improving the working memory and cognitive flexibility of the elderly and there was no difference between the two types of physical and cognitive rehabilitation programs (P> 0.001) According to the findings, combined rehabilitation programs can be effective in improving the working memory and cognitive flexibility due to the focus on both physical and cognitive aspects.

In the last decade, the tendency to use Blended learning across the globe has grown steadily due to its benefits and attributes, and to address the weaknesses of e-learning and face-to-face Instruction. The purpose of this study was to investigate the effect of Blended Learning based on Gardner's multiple intelligences on students' learning and to compare it with the face-to-face approach. The study population included all students enrolled in Tehran Farhangian University of Primary Education. This quasi-experimental study was carried out with pretest-posttest with  a control group in the academic year of 2016-2017. A total of 40 female college students participated in this study. They were selected by the available sampling method and randomly divided into two groups. Data collecting tools was a questionnaire of multiple intelligence profiles with 80 items, a questionnaire measuring the level of learning by comparing pre and post-test. Both experimental and control groups trained in eight 90-minute sessions. The control group was taught using face-to-face traditional Instruction and the experimental group along with Blended learning and network-based learning, went under Blended Instruction based on multiple intelligences using articulate engage software with educational media (text, audio, image, animation and video). To design learning activities, learners were grouped according to their predominant intelligence, which was measured through the multiple intelligence profile. In both groups, the pre-test and post-test were the same academic achievement. Data analysis was performed using SPSS 19 software. Findings of the research indicate that the level of students' learning in the experimental group has significantly increased in comparison with the control group after having participated in the Blended Learning based on multiple intelligences
