Özet:
In this study, it was aimed to evaluate the attainable level of achievement of “cellular
division and inheritance” from the unit in grade 8 science and technology curriculum.
The research was conducted in a descriptive survey model. The study group of the
research consisted of 80 8. grade students in 2 different schools, selected by purposeful
sampling in Elazığ city centre in the academic year of 2014-2015. As a data collection
tool, a multiple-choice success test was prepared by the researchers. In the substance
analyses made as a result of the pilot application, the mean differentiation of the test
was found to be ravg= 0.43. The reliability coefficient (KR-20) of this test, consisting of
30 items, was calculated as 0.81. In the analysis of the data, absolute success
percentages were calculated which showed the level of achievements reached on the
five subtopics of the concerned unit. According to the results obtained, the attainable
level of achievement of “cellular division and inheritance” unit is as follows for each
sub-problem: With respect to "mitotic division, 80.31%"; "62.8% for inheritance",
"62.1% for meiotic division", "67.4% for DNA and Genetics" and "52.2% for adaptation
of living beings to environment and evolution". It was also seen that 14 of the 30
target behaviours included in the unit were acquired by the students.
