What I Can Reflect about Psychological Aspects, If the Student is Confronted with the Function Questions

1. Determine the formula of function g(x)= x – 1 and find the value for x = -4 and x = 3!

2. Determine h (-5) if h(x) = -3x + 4 and find the value of c if h(c) = -8!

The above questions about function which was delivered in Junior High School by mathematic teacher. Every student has different respond with above questions. Most of mathematic teacher deliver the knowledge with conventional method or teacher center so the student always wait the teacher give the solution of the question which have been given by teacher.

The teacher should know about function deeper so the teacher can control the student. This is definition of function ,A function ƒ from a set X to a set Y associates to each element x in X an element y = ƒ(x) in Y. Note that X and Y need not be different sets; it is possible to have a function from a set to itself.

Most of the student have psychological aspects, If the student is confronted with above question, we can clasificate it to three step, they are When the student look and get the questions, when the student try to solve the questions, and when the student have finished the questions.

· When the student look and get the above questions

When the above questions given to the student, most of students annoyed. In their mind “it’s not important for me”, “I don’t know the solution”, “Who and what is X and Y??”, “Why must X and Y”, ”Are the questions have solution, I think aren’t” etc. They regard the function hasn’t connection with their life.

But there are several students that enthusiast with the question. They feel challenge to find the solution and then they begin try to thinking finished the question.

· When the when the student try to solve the questions

After they are given the question, they try solve and finished the problem. The students who aren’t ready before and he don’t like mathematic will solve the question slowly. On the other hand the student who ready before will find the solution fastly. They fell happy when solve the problem.

· When the student have finished the questions

The student who find and finished the problem will happy, enthusiast, and smile. They curious to solve other problem. While, the student who can’t find the solution will sad and trauma to solve the same problem again.

The The readiness, do exercise, and the result are very important in teaching and learning. If the student ready to participate teaching and learning so the student will get the knowledge easy and fastly. If the students often do exercise, they solve and finish the question easily. If the result is good and they find the solution of problem they will happy and enjoy the lesson.
