The aim of this study was to compare the effectiveness of two methods of cup stacking game and transcranial electrical stimulation of the brain (tDCS) on cognitive inhibition, auditory attention and visual attention in students with attention deficit syndrome in 2019-2020. The present study was a quasi-experimental study with a pretest-posttest design and a control group. The present study population consists of all fifth and sixth grade elementary students with symptoms of attention deficit in Tehran in 2019-2020. Among the fifth and sixth grade students, 45 students with attention deficit symptoms were selected by convenience sampling and randomly assigned to three groups of 15 people including the brain stimulation group, the cup stacking game group and the control group. The tDCS experimental group was treated for 10 sessions of 30 minutes, and the cup stacking experimental group were exposed to ten 30-minute sessions of cup stacking game. In order to evaluate the research variables, the continuous auditory visual function test (IVA) of Rosvold, Sarason, Bransome, and Beck (1956) was used. The results of mixed analysis of variance showed that cup stacking game and tDCS are both effective in improving cognitive inhibition and auditory attention of students with attention deficit syndrome, but there is no significant difference between the two methods in influencing cognitive inhibition and auditory attention (P> 0.05). Also, only the cup stacking game had a significant effect on improving visual attention, but tDCS did not have a significant effect on improving visual attention.

Abstract The present study is a qualitative research with a phenomenological approach that has been conducted to identify the dimensions and components of professional development of primary school principals and to develop its framework. The statistical population of the study was the principals of public primary schools in Tehran in the academic year of 2019-2020. In two stages of sampling, samples were selected by quota and then purposive sampling methods. Semi-structured interviews were used to collect data. The interview continued until the data exploration and data collection process reached a theoretical saturation point after interviewing 14 people. Data were analyzed by open and axial coding steps. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. To determine the reliability, two methods of reviewing the writings and also the method of recoding were used. The agreement was calculated in the coding homogeneity and the agreement coefficient was 86%. Findings showed that the professional development framework for primary school principals has 3 dimensions, 14 components with 117 indicators  Which includes : the content dimension of professional development (with components of general management knowledge, specialized management knowledge, interactive skills, resource management skills, professional skills, personal inclinations, managerial attitude, physical and mental ability and intellectual ability), the dimension of professional development process (with the components of self-development actions and developer relations) and the dimension of organizational requirements (with the components of knowledge acquisition and acquisition of skills, modification of selection and appointment methods of managers, improvement of organizational structure and processes).
