Abstract

The purposes of this research were 1) to construct a diagnostic test of mathematics learning deficiencies on Fractions for  students with learning disabilities in lower schools for inclusion, 2) to validate of a diagnostic test of mathematics learning deficiencies for  students with learning disabilities in lower schools for inclusion in terms of content validity, difficulty, discrimination, and reliability, and 3) to diagnose mathematics learning deficiencies for  students with learning disabilities in lower schools for inclusion. The participants of this study consisted of students with learning disabilities in inclusive schools under the secondary educational service area office 1 and 2 in Bangkok for the 2020 academic year. The research instrument was a multiple-choice diagnostic test of mathematics learning deficiencies concerning fractions. The results of the research are as follows. 1. The results of a diagnostic test followed the procedure, the result is construct a diagnostic test of mathematics learning deficiencies on fractions 1 test was a 4 multiple-choices, 50 items. This allows the test results to be taken into account for student deficiencies in each learning objective. 2. The results of the quality examination of a diagnostic test of mathematics learning deficiencies on fractions revealed that the content validity of the mathematics diagnostic test was 0.80 to 1.00, the difficulty was 0.20 to 0.83, the discrimination was 0.23 to 0.73, whereas the reliability was 0.84  3. The results of diagnosis of learning disabilities of Mathematics on fractions revealed that the students had learning disabilities of Mathematics on fractions with an average score of not passing the criteria which in order of the most deficiencies is the matter of addition and subtraction of fractions. In the case of unequal denominators, whereas their minor deficiencies were comparison of fractions, division of fractions, and definition of fractions.
