WHEN THE STUDENT IS CONFRONTED WITH PROBLEMS ON LINEAR EQUATION

If a studebt is confronted with some problems on linear equation and he masters the material, absolutely he will very emnthusiasme to solve it. but sometimes a student will be bored because related to Lewin Theorem with his famous psychology theorem that is medan theorem or field theorem, there said that if there are too many replies happened will cause a bored situation on it.
But it's gonna be different if the student is not mastering enought the material. he maybe confuse, unhappy to face that thing, and maybe uninterested with the subject.
here they are some feelings that maybe in the student's mind that time :
1. happy
2. emnthusiasm
3. motivated
4. satisfied
5. unhappy
6. sad
7. angry
8. lazy
9. confuse
etc

According to motivation theorem from http://www.psb-psma.org/content/blog/teori-teori-motivasi, here they are something that affect the somebody’s motivation :
1. His perception of his self
2. His hope
3. His needs
4. His dreams
5. Surroundings situation and condition


In my opinion, mastery of the material, good facility, friend's motivation, and motivation from the teacher play big role for the student's motivation. To be success, a student not only must have enough ability to solve the problems, but also good skills, creative strategy, good spirit for survive on trial and error.
So, what would happened on a student when he found a trouble? In my opinion, here they are the probability :
1. They will ask to the teacher
2. They will ask to the other friends
3. They will make a group of discussion
4. They will read more book
5. They will search the answer on internet

In this topic, LINEAR EQUATION, usually students have errors on calculating the value of the variable. The other error's probabilities are in determining the certain place of x area. Area here means place/field/region.
BY substituting just any value of x we can determine whether the area of x is in the right side of the limit (value of x) or in the left side of it. But here we have the easier way to determine the side area of x.
If x > t , the area of x is bigger than the value of t, so it is in the right side of t
If x < t , the area of x is smaller than the value of t, so it is in the left side of t.
