The
cell, as the amazing unit of life, is the smallest structure of living which
acts as a thing alone and can carry out all the vital functions of life. The
technological developments and multidisciplinary studies provide new
opportunities to understand the structure of cell continually. According to
these studies, the target is to determine the knowledge levels of high
education students on the basic part of cell and organelles as part of their
drawings. The students are asked to draw
an animal cell and to state the names of the organelles with the basic
parts of cell. In this respect, it has been studied on their conceptual
knowledge levels upon cell. This study has focused on totally 286 students of
9th, 10th, 11th and 12th classes on three different high educations in Kars,
city centre , in 2014-15 Education Year.
Although
the students are asked to draw an animal cell and to show the parts, they have
drawn chloroplast and cell wall which are not in animal cells and are the parts
of plant cell. This manner demonstrates that the high education students have
less misconception on subjects of animal and plant cells. As a result of
surveys, in all of 9th, 10th, 11th classes, it is obvious that they have stated
the core as the basic part of cell; yet, in the 12th classes, the students have
stated the mitochondria as a cell organelle in their drawings. The cell nucleus
is the most stated cell structure respectively %82, %76,6 and %86,3 in 11th
classes; mitochondria is the most stated one in 12th classes at the rate
of % 96,7 in the drawings of the
students. The cell nucleus as basic structure of cell, cytoplasm and cell
membrane; mitochondria as cell organelles, ribosome, golgi apparatus, tonoplast,
endoplasmic reticulum,lysosome and centrosome have been the parts of animal
cell the students in the study all carry out in their drawings. This matter
also indicates that they clearly have learned these structures and organelles
as syllabus in science and technology lesson of high students as well as in
biology lesson of high education students as they repeat. Of all these
organelles, especially golgi apparatus and lysosome have been increased at the
rate of %46,2 and %40 compared to previous year, they have become the best
known organelles. While the nucleolus has not been stated by the students of
9th class, RNA, chromosome, chromatin fibre and pore have been only stated by
the students of 12th class as cellular structures.
