A Psycology Symptom from the Junior High School’s Student in Study Mathematics

1. Question

A chicken’s cage will be made in form of rectangle. Strand of metal length which available to making cage is 16 metres.

1. If cage length of x metre, expressing width in x!

2. Determine formula of L(x), that is function of wide !

3. Determine the measurement of cage in order to get maximum area!

4. How much is wide [of] maximum that cage?

The answer of responder

1. The circle of length square (K) = x

The width of cage = l

K= 2x + 2l

16 = 2x + 2l

2l = 16 – 2x

l = 8 –x

2. L (x) = p x l

= x ( 8 – x )

= 8x – x²

3. In order to get a maximum area, so:

= 4

So The length is 4 and the width of cage is 8 – 4 = 4.

4. The maximum wide = L (4)

= 8 (4) - 4²

= 32 – 16

= 16

3. Observation

Interview

Question 1 : What is your opinion about your mathematics teacher ?

Answer : He is a pleasant teacher.

Question 2 : How was your feel if you meet mathematics education ?

Answer : I like mathematis so I feel confort if I meet mathematics lesson. Beside that. The teacher uses appropriate methods, so the education system is no boring.

Question 3 : what is the methods that your teacher use ?

Answer : My teacher uses cooperative learning so the education is confortable.

4. Conclussion

A responder psychological symptom when he was doing the task is he felt happy. He finished the task with appropriate. The question is medium task. From the observation above, we conclude that to increase mathematics ability, the teachers should developted their quality of education. They must use the appropriate method to reach a goal eduation system.

From the observation above, we can conclude that the result of given mathematics question for respondent is mathematics is not difficult. If we have to like mathematics, we should don’t think that mathematics is difficult lesson
