Small Research of Psychological Symptom to SMP Student

At this opportunity, i will try to perceive psychological symptom from a child of SMP. This Matter I do by giving 1 problem / question to child, this problem for the student class of IX and this problem pertained easy to. Next, I look for correspondent and i order him to do the problem. Afterwards I will perceive psychological symptom that happened moment of coresponden doing the problem. The observation at saturday, 27 december 2008, in coresponden's home.

The correspondent :

Name : Bella Aditya Kurniawan
Genre : male
Age : 15
School : SMP Muhammadiyah, Purworejo
Class : IX

Question:
1. A cone has volume 1004,8 cm3. Radian of pallet area circle 8 cm. If π= 3,14 cm. Counting :
a. high of cone
b. length lines artist
c. wide of cone blanket
Answer:
a. V= 1/3 π r2 t
1004,8=1/3.3,14.8.8.t
1004,8= 1/3.3,14.64.t
1004,8= 1/3.200,96.t
t= 1004,8 / 1/3.200,96
t= 15 cm
b. length lines artist : s = Vr2+t2
= V82+V152
= V64+V225
= V289
= 17cm

c. wide of cone blanket= L = π r s
=3,14. 8. 17
= 427, 04 cm2

After correspondent accept problem and have done the problem, in the reality correspondent fell some difficulty. Difficulty by coresponden because of enumeration of number in the problem fair to middling is difficult, caused by its comma and entangle number which many over there. Besides correspondent find difficulties moment problem which point c, coresponden find difficulties because correspondent forget formula of it, so correspondent have to again open his note for can do it. At the moment Coresponden do problem of point c, finding difficulties because of correspondent forget than its formula, so that correspondent have to reopen its note. This matter because of coresponden practice seldom, and seldom reopen its note at home.
Basically correspondent do not so take a fancy to Iesson of mathematics. This matter because of teacher which teaching in inconvenience school so that correspondent feel lazy at Iesson of mathematics in school. Coresponden haven't motivated high of at Iesson of mathematics in school, and at home seldom learn again. But at there is test of correspondent will have high motivation and will learn more impetous than previously.
See from result of perception which have been done to correspondent and after analyzing statement given by correspondent, so can be pulled some conclusion:
1. Correspondent find difficulties doing problem because seldom exercise the problem, so that its formula forget. This Matter very relate to law readiness and practice law.
2. Correspondent have psychological symptom related to study that coresponden frown upon mathematics because its teacher unpleasantly teach at school.
3. Correspondent also have psychological symptom to study of mathematics. Correspondent haven't motivated high at Iesson of mathematics in school, but at before test of coresponden will have high motivation and will learn more impetous again from usually.
