Sometimes students lose their concentration into the classroom and not grasp the topic properly and hence lose their interest in the subject (s). As a result of bad score bad performance. So, how to be attentive every time in the class? To find the answer to this question we have to first find out the reasons for it, why a student lose their concentration?

1. Classroom attention

As we know that admission in any reputed University/Institute is difficult and we do many efforts to get the admission of our interest stream/course. When we join any new class we forget about the hard work which we have done for the present class, as a student. Being a human it is the tendency of our minds to attract the other people by our actions without thinking its good or bad impact. Sometimes this tendency becomes dominant over the common actions of that particular place, which we have to perform, like focus on study in a class. For this distraction, friends are responsible or I myself take initiative to distract the concentration of my surroundings, i.e. friends and/or myself. This thing only one student can check. (In short, the student does not remember the hard work which he did in past and tried to impress other people in present.)

A family, relationship or medical problem can also disturb the student’s behavior and he can lose their interest in the assigned work. Also, laziness can play the same role, the student is not healthy or have eaten enough food during the lunchtime, then students will feel sleepy and can not concentrate on the lecture.
But what is an important factor here, does student know that what he is doing and what will be the impact of it’s on him in future? If the student is aware and knows these are the points which are creating a distraction to him in the class he can improve but if not aware then the student can be a problem for both teacher and parents in future. So, timely information and awareness are also important.
Here above, I have discussed the points, keeping students perspective in mind but this distraction among the students can be due to a teacher and their teaching methodology. The teacher is also responsible to distract the student concentration, so interaction with each student during the class hour or later is important. But in this case/situation, one of my suggestions to the student is, that they observe the teacher what he is doing, what he is telling or what diagram or picture he is trying to show or explain, you just try to note down that and watch that duration like a movie. I am sure you will enjoy the day.

2. Interaction with teacher

This is an important factor, it has also been observed that students who frequently interact with their teachers are more confident in all activities as compared to those who hesitate to interact with their teachers. Interaction with the teacher gives students moral support and encouragement. The teacher should participate along with the students in any activity or join a birthday party or similar activities, where students get to know about the life of their teachers. I am sure they will impress with your lifestyle and will motivate to do more good works for society.
The interaction should be genuine and within the boundary, the teacher should know first about the boundary and students should know about the limits of interaction. The interaction with the teacher also creates an interest in the subject. It is very difficult for one who criticizes the teacher and could get good marks in that subject (might be the exceptional case), the reason is not a teacher but the interest in the subject taught by that teacher. If you will interact with your teacher, never you can criticize or complain about to him and will also enjoy the subject.     

3. Group discussion

 This activity is possible only when you have some information about the topic (s) on which you have doubt and you want some other possible views which makes your picture more clear about the topic (s). Group discussion is one of the most important tools of study where one come to knows more possible views of a topic and observe the different vision of the same problem. Not help only in logical development but also improve the confidence in public speaking. Group discussion helps to remember the facts of your course and chance to learn with fun, with a free mind. This is the best and short cut method to learn things in a short time also. A group discussion remains healthy when group size is small and all the people are of the same frequency and knows that they are here for learning. One has to focus on time, so it should be time bound also.

4. Class Notes & Homework

 This is the most important thing which you have to follow daily and it should be part of daily routine. Prepare your class notes daily, follow the textbooks and make perfect notes in the separate notebook. Actually, the class notes are not complete notes in any case, you have to read books and prepare a good notebook for the concepts, derivation and numerical. 
There is no short cut method into the learning, so you have to work hard from the day first. If the teacher gives you any homework whether that is small or a big amount of the numerical problems, you have to show that on or before the due date. It will develop good and healthy habits in your mind which will be useful in the future. Take the help of seniors to complete the assignments or any type of homework. Good class notes help during the examinations. Try to write your idea, explanation in your own language in a box with a different color of pencils.

5. Standard Publisher/Authors Text Books

Read always good publisher and authors book, these books remain free of printing and/or symbols mistakes. Also, they cover good quality of material, their explanations always follow a reference and gives a good presentation of the course. While local authors try to make simple language and reduce the material of the books so as a result there is a possibility to change the meaning of that concept and incomplete information for the same.

 6. Question asking technique

What is this? This part is very important when you interact with your teacher and discuss in a group. Usually, students ask the question directly, like, what are day and night? What is Semiconductor Laser? What is the population inversion? or What is time dilation? What is the Hall effect? What is the earth? etc. I personally feel that in a class, where the teacher already told about the topics, then during interaction with the teacher asking this way of question is not right. As we know, after the lecture delivery into the class, students are supposed to read textbooks and make a proper note, in this process student, get an idea about the topic. But, to reach up to a depth of the topic there are some more steps, where the student’s concept is not clear or have some doubts/confusion. Then students don’t need to use or ask in this way that what is ……? Student first explain the point that I understand up to here in this particular topic and when I was trying to understand this statement or step I could not make my idea more clear, or student has to note down both the ideas of his mind on that topic, where, because of that he is facing confusion. In this way, a teacher can help in a better way to make the concept more clear. Obviously, this will improve the understanding and vision to see and solving many problems. This idea you can understand better with this classical example; If suppose you ask an address of your friend’s house to someone in a big city, the person told you about the way,  to approach that sector where your friend is living and location of the house. In this case, if you forget the way or somehow be confused that,  which path you have to follow, then again you ask for someone and follow the right path, to find the exact house. In this process, you did work (move some steps) for searching the house to find the friends. Similarly to make the concept more clear you have to follow the steps, (that path) and if you face the problem (confuse about the right path) then ask the right way, in this process you have to cover at least some distance to approach the target (i.e. knowledge). 

 7. Self-expression

If you are not able to express your idea clearly then you will face the problem to understand the concept. You have to speak openly without any hesitation. Whenever you get the chance to speak at any platform you have to use that. Regularly you have to develop your self for the betterment. Say always whatever is in your mind. This is also one of the important tools in the development of a student’s life. So, don’t ignore it. Meet with the people tell them about yourself and listen about them.   There are so many things which you can solve through this technique i.e., self-expression. Use it effectively and do work on it every day.
