THE DISCRIMINATORY VARIABLES OF SCHOOLS THROUGH THE HIGH AND LOW ORDINARY NATIONAL EDUCATION TEST (O-NET) IN LOEI PROVINCE, 2011

Abstract

The purposes of this research were 1) to analyze variable discrimination of
schools between the high and low Ordinary National Education Test (O-NET) in Loei
province, 2011 2) to study equation discriminating schools with the high and low
Ordinary National Education Test (O-NET) in Loei province, 2011.
The population used in the study was 137 Matthayomsuksa 3 schools. The
sample size was divided into two groups between the high and low Ordinary National
Education Test by taking the average of the 8 subjects in each school to sort out from
the most to the least score. The selection of the sample size for the proportion of 50 :
50 was applied to have 100 school samples. 50 schools with the highest average of
O-NET and 50 schools with the lowest average of O-NET were researched. Informants
were 2 groups including 100 school administrators and 800 teachers in 8 learning
groups from Matthayomsuksa 3 schools, with a total of 900 informant including Social
Study, Religious and Cultural, Foreign Language, Mathematics, Science, Health and
Physical Education, Art and Career and Technology. Questionnaires were collected
and analyzed by mean, standard deviation, coefficient distribution, correlation among
variables and stepwise categorizing analysis.
The findings showed as follows :
1. There were 4 variables identifying schools with the high and low
Ordinary National Education Test in rank order from the school setting (X18), medium
size schools (X142), attitudes towards the teaching (X6) and the proportion of students
per classroom (X16).
2. Equation of category discrimination could correctly predict group
member at 84.00 percents which showed in raw and standard scores as follows.
The discriminating equation in raw scores was
= -13.265 + 1.348 X18 + 1.693 X142 + 1.352 X6 - 0.048 X16
The discriminating equation in standard scores was
= 0.691 ZX18 + 0.562 ZX142 + 0.554 ZX6 - 0.435 ZX16

3. When considering variables in Equation of category discrimination, the
school setting, medium size school and attitudes towards the teaching tended to
characterize the high Ordinary National Education Test, in contrast to the proportion of
students per classroom, it was tended to be the low Ordinary National Education Test.
