A STUDY OF VARIABLES AFFECTING ON A QUALITY ASSESSMENT OF MATHEMATICS SUBJECT BY USING VALUE ADDED ANALYSIS ON TIMSS 2011

Abstract

The purposes of this research were 1) to study results of characteristics variables of students and schools towards the quality assessment of mathematics subject in the countries with high test scores – Republic of Korea and Singapore; and 2) to compare the similarity and difference of characteristics variables of students and schools towards the quality assessment of mathematics subject between Republic of Korea, Singapore and Thailand. The secondary data from Trends in International Mathematics and Science Study (TIMSS 2011) was used in this research. The samples were students, mathematics teachers who taught the student samples and executives of schools where the student samples were studying by dividing into: 150 schools and 5,166 students in the Republic of Korea; 165 schools and 5,927 students in Singapore; and 172 schools and 6,124 students in Thailand. The research specifically focused on mathematics subject with 14 papers of knowledge evaluation test on mathematics. There were 4 steps of data analysis – 1) To Organizing data according to the study factor 2) To estimate competency of students from the assessment of their mathematics proficiency by using MULTILOG program analysis of data; and estimation on competency of students from assessment of their mathematics proficiency by using MULTILOG program in 3) analyzing the value added in the model of quality assessment by applying the Value-Added Model with Hierarchical Linear Modeling (HLM) with 2 levels of analysis; and 4) comparing the similarity and difference of characteristics variables of students and schools towards the quality assessment of mathematics subject.
