Understanding of the concept of variable, unknown and parameter by students in the third grade of high school
Summary:
This paper attempts to study the level of understanding the concept of
variable, unknown and parameter by students in the third grade of high school.
For the purpose of this research, questionnaires were given to students at the
beginning of May. The students who participated in the survey, are students of
a high school in the East Attica. The teaching of the course was held in
accordance with the Official Curriculum and textbooks.
It was appropriate for some students to give interviews to clarify some
ambiguities as well as some others, that their responses to the questionnaires
contained research interest, be queried further.
The responses of the students and their interviews were the export and editing
material findings.
From responses of pupils in written or oral, rather negative conclusions were
exported as far as the pupils' understanding of the concepts of variable, the
unknown and the parameter was concerned.
It was found that students find it difficult to translate the natural language
into algebraic, to form the equations, the inequations or the systems arising
from problems.
Students solve equations following instructions and algorithms contained in
books or given by teachers.
At the end of the work findings regarding the students are spelled out in
detail as well as suggestions-teaching views regarding the teachers.
