Given the significance of teacher care and its impact on student motivation, stroke as a unit of recognition seems to be related to motivation for class attendance and language learning. In this regard, this paper aimed to investigate the role of stroke in students’ willingness to attend classes(WTAC) and their foreign language achievement (FLA) in the foreign language context. To this end, a scale was developed and validated through structural equation modeling (SEM) to measure learners` WTAC. A total number of 260 English as a foreign language (EFL) learners completed the newly developed scale along with the stroke scale. Regression analysis was used to examine the relationships among the variables. The results demonstrated that WTAC, Non-verbal, and Valuing subscales of stroke were the strongest predictors and Teacher Characteristics (TCH) subscale of WTAC was the only predictor for FLA. Finally, the results were discussed, and some implications were provided for educational settings. تاثیر نوازه بر تمایل به شرکت در کلاس درس و یادگیری زبان خارجی با توجه به اهمیت توجه معلم و تاثیر آن بر انگیزه شاگردان، نوازه به عنوان واحد دیده شدن افراد، به نظر می رسد با انگیزه شاگردان برای شرکت در کلاس و یادگیری زبان ارتباط دارد. در همین راستا، در این پژوهش به دنبال بررسی نقش نوازه در تمایل به شرکت در کلاس درس و یادگیری زبان خارجی هستیم. بدین منظور، پرسشنامه ای برای سنجش میزان تمایل برای شرکت در کلاس با مدل معادلات ساختاری تهیه و هنجاریابی گردید. از 260 نفر فراگیر زبان انگلیسی خواسته شد به این پرسشنامه و پرسشنامه نوازه پاسخ دهند. از تحلیل رگرسیون برای بررسی ارتباطات بین زیر سازه ها استفاده شد. نتایج نشان داد پرسشنامه جدید با زیر سازه غیر کلامی و ارزشیابی نوازه و ویژگیهای معلمی با یادگیری زبان ارتباط معنادار دارد. در پایان، نتایج بحث شد و برخی از کاربردهای این پژوهش برای محیطهای آموزشی ارایه شد.   کلیدواژه ها:نوازه، تمایل به شرکت در کلاس، حضور در کلاس، یادگیری زبان خارجی

Loss of balance and postural control are the main reasons for falls among the elderly adults that are considered as serious elderly health challenges with high impacts on the quality of life. The cerebellum is involved in postural control as one of the key neural structures that receives many inputs from the sensory systems. Cerebellar transcranial direct current stimulation (ctDCS) is a popular noninvasive and safe method enabling the adjustment of cerebellar activity. Therefore, we investigated the effect of ctDCS on postural control variables among elderly population with a history of stroke. Thirty elderly individuals (60-75 years) participated in this study. After preliminary assessments of postural control strategies by post urography at six sensory conditions, they received five 20-min sessions of active ctDCS at 2mA (intervention, n = 15) or sham stimulation (control, n = 15) in a random manner. At the end of the stimulation process, postural control strategies were reassessed. After adjustment for pre-test values using the ANCOVA test, an improvement of the subjects' performance in the first four conditions was observed in the intervention group compared with the control group (P < 0.05). However, in the fifth (P = 0.24) and sixth (P = 0.58) conditions, there were no significant differences between the groups. The results of this study showed the significant effect of ctDCS on the postural control strategies. These improvements were reflected by normalization of strategy of postural control in elderly adults.
