What I can reflect about psychological aspects if the student is confronted with the following questions?

Teachers should can understand their student’s skill and ability. Therefore, when they give some problems or questions, they also have to consider and adjust the problem with student’s ability in order that will appear good psychological aspects from students when they get the problem or question.
This time, I’ve got a assignment from psychological of study mathematics lecturer, Mr. Marsigit about “What I can reflect about psychological aspects if the student is confronted with the following questions?”

Questions :

1. Tentukan himpunan penyelesaian dari SPNLDV berikut,
a. (5/x)+(4/y)=-2dan(-3/x)-(6/y)=(9/4)
b. (3/a)+(2/b)-(5/2)=0dan(2/a)+(4/3b)=(5/3)
2. Ani dan Budi pergi membeli buku dan pensil di toko buku. Harga pembelian buku dan pensil mereka dapat kamu lihat pada tabel 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 kiligram jeruk.
4. Rudi sedang menghitung uang sakunya bulan ini. Uang saku Rudi terdiri atas lembaran sepuluh ribu rupiah dan lima ribu 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.

This assignment is meant to give us a description about “teacher” with their role as facilitator of student.
I still remember when I found some questions as number one when I was in junior high school. In beginning, I also felt confuse how I could solve the questions. Then I asked to my teacher about it directly. And my teacher said that we could solve it by multiplying each equations with “xy”, then it could be finished by substitution or elimination method. I tried that ways and I could get the solutions. In other hand, I also got the other solving way in senior high school. We can get the solution by let “(1/x) = a” and “(1/y) = b”, so will appear linear equations with two variables, they are a and b. then we solve it by using substitution or elimination method.
From my experiences, I can say that number one questions are rather difficult to junior high school students. How much more if they never get the material/subject from their teacher before and never get exercise about it. As “Law of Readiness” by Thorn Dike, if we have readiness to do or study something, we will enjoy in studying and understand subject easily. But, that also depend on student’s skill. They will feel confuse, afraid when they get the questions for them that like mathematics but they have not known the way to solve it. It is different for them that have no care to mathematics. Although they cannot solve it, they will never think about it and will depend on the other students. And for them that are usually with that questions, they will be happy and have good confidence with the questions.
Beside that, I also try to give the questions to a student of junior high school. Her name is Vina. Beginning, she asked to me how to solve the question number one. And then she could solve the other questions (number two until four) by her self fast and exactly. I think, it happens because the questions of number two until four are application questions of linear equation that are in connection with ordinary life. So, student will be more easy to remember it. Therefore, the students will be happy and optimistic to solve the questions.
We can conclude that as a teacher, he/she has to understand student’s skill and ability. So, he/she can measure and evaluate study’s result of student well. And also, get exercise in studying mathematics is very important. It is meant that student can remember and understand the subject easily.
