*What I Can Reflect about Psychological Aspects,
If the Student is Confronted with the LINEAR EQUATION Questions*

My opinion about psychological aspect if the students is confronted with the following question:
1. Tentukan himpunan penyelesaian dari SPNLDV berikut.
a. 5/x + 4/y = -2 dan -3/x – 6/y = 9/4
b. 3/a + 2/b = 0 dan 2/a + 4/3b = 5/3
2. Ani dan Budi pergi membeli buku dan pensil di took buku. Harga pembelian buku dan pensil mereka dapat kamu lihat pada table berikut.

Pembeli Buku Pensil Harga
Ani 2 3 Rp. 7.200,00
Budi 3 2 Rp. 7.800,00

Tentukan harga satu buku dan satu pensil.
3. Rina dan Santi pergi ke supermarket. Rina membeli lima kilogram apel dan satu kilogram jeruk Rp.60.000,00. Santi membeli dua kilogram apel dan tiga kilogram jeruk seharga RP. 50.000,00. Tentukan harga satu kilogram apel dan satu kilogram jeruk.
4. Rudi sedang menhitung ang sakunya bulan ini. Uang saku Rudi tediri atas lembaran sepuluh ribu rupiah dan lima rib rupiah. Jumlah seluruh lembaran uang saku Rudi 8 lembar. Adapun jumlah uang saku Rudi seluruhnya adalah Rp. 65.000,00. Tentukan banyaknya setiap lembaran uang saku Rudi tersebut.

In the first time and first impression looks the question above the students will fell confuse because the question seem complex, complicated and challenging. However, if the question comprehensible reading by students, they will think that the questions above are simple and realistic. The solutions are not difficult to find out if they have the materiel and master the concept. Therefore, they will enthusiast to solve this problem.

AN ANALYIS OF

SELECTED COGNITIVE ABILITIES AND

IT’S RELATIONSHIP WITH ACADEMIC ACHIEVEMENT

IN MATHEMATICS

The relationship of academic ability to differences in cognitive abilities measured is significant. Consistently, high ability learners, whether based on primary or secondary test scores, significantly outperformed low ability learners on total cognitive ability. According to school subjects, interestingly performance in English and Science is more related to the selected cognitive abilities of students as reflected in the relatively high coefficients reported. It is probable that in these two school subjects, cognitive skills such as deductive thinking and analogical reasoning are encouraged.

Surprisingly, the mechanical comprehension subtest was a poor predictor of performance in the subject Living Skills though it teaches technical elements such as understanding And repairing of household appliances. However, Living Skills also includes non-technical aspects such as commerce which may not be related to mechanical reasoning. The study found that among the school subjects, mathematics reported the highest correlation with spatial ability which is consistent with the findings of Guay & McDanial (1977) and Wong (1992). Overall, academic achievement plays a significant role in influencing the cognitive abilities of students in the sample studied. The higher cognitive abilities of students from high income families suggest that such abilities may be better nurtured in these families. Greater opportunities for the development of such skill may have been made available for learners from such advantaged families through reading materials, thought challenging games and activities and perhaps a generally more conducive environment that encourages such types of thinking.

In terms of gender, males outperformed females in spatial visualisation. This finding is partially consistent with earlier studies wherein females scored lower in spatial ability than their male counterparts. Wong (1992) found that males performed better than females in spatial visualisation and spatial orientation. The present study found gender differences was only for spatial visualisation. In fact, females scored higher in spatial orientation than males though the difference was not significant. Generally, this study reveals that there is evidence for individual differences in cognitive abilities between students in the sample and suggests that the Cognitive Ability Test be administered to a larger sample to detect developmental differences and the establishment of norms.
