Currently, educational processes are part of essential development programs for human resources, and cover students of each community. Improving the quality of education in universities is not a new phenomenon. It explains academic performance of university planners, and helps design strategies to improve the functioning of universities. Educational factors include various physical, financial and human factors that facilitate education in the community by establishing coordination and appropriate activities (

2). Many elements in the existing educational system have a special place that cannot be ignored in education. Since teaching is not easy, professors in the course of teaching are not comparable with none of the other elements (including managers, deputies, and etc.) because the professors, considering the individual characteristics of the students in the classroom, through the appropriate combination, the use of creative teaching methods and techniques, and the equipping of classes in the educational system, can move them to the transcendental goals or disappoint them. Most of the feedback from these activities is visible in classrooms where thoughts are displayed, analyzed, or criticized. The most common teaching style is oral communication between professors and students and among students (

4). However, no presence at a dynamic classroom disrupts learning and teaching (
5). Some experts believe that the presence of students in the classroom should be supervised, encouraged or even enforced. The sense of lack of control over the classroom environment by students decreases the probability of their active participation and attendance in classrooms (
6). The importance of attendance and absenteeism for professors, the attractiveness of content, the ability to take notes in class, the correlation of materials with the student's major, the creation of sense of curiosity in the early lectures, feedback, class content, and faculty behavior are among the most critical factors affecting the attendance of students in the classroom (

9). The results of a study at Queensland University have shown that attending a classroom is the main way by which students can acquire scientific and practical knowledge, skills, and professional ability (
8). In addition to attending classrooms to learn subject matters, the prerequisites for students’ learning are doing correct tasks and academic achievement that increase students’ level of concentration (
9). Concentration is acquirable and is referred to the mental state in which all the senses and mind of the human are focused on a particular subject (
10). The lack of concentration in classrooms, especially student seminars and conferences is among common educational problems. Usually, most people who eagerly attend a session lose focus and sidetrack over time, while individual’s concentration increases if distraction factors reduce and mental and environmental conditions change (
11). Various studies have mentioned some of the factors influencing concentration including nutrition, intellectual conflicts, sufficient knowledge and information of professors, mastery of the subject, classroom teaching method, the use of teaching aids, the light, and ventilation of the classroom (
12). Also, according to the video data collected by Raca and Dillenbourg, even the placement and seating of students in classrooms and the use of visual technologies can play an important role in increasing concentration (
13). In addition, studies conducted by Servatyari et al. and Haresabadi et al. showed that multiple and effective strategies can be used by planners and teachers to increase student concentration (

15).
Concentration is relative, and nobody can claim that they are completely distracted, or are always concentrated, but it can be improved and strengthened by changing some of the existing factors (
16). Active presence of students due to positive interaction with professors not only increases their motivation for concentration on learning, but also affects their activities in future.
