The Development of Diagnostic Tests by Computerized Programming in the Mathematics Learning Strand on Multiplication and Division for Phatomsuksa 4 Students under The ChiangraiPrimaryEducation Service Area Office 2.

Abstract

The purposes of this research were to analyze wrong answers and debugging on Multiplication and Division, to analyzeto determine the quality of the test by a diagnostic test  by a Computer Program in Mathematics Subject for Prathom Suksa 4 Students on Multiplication and Division, to analyze basic statistics of the test by a diagnostic test  by a Computer Program in Mathematics Subject for Prathom Suksa 4 Students on Multiplication and Division and to efficiency evaluation of the test by a diagnostic test  by a Computer Program in Mathematics Subject for Prathom Suksa 4 Students on Multiplication and Division. The population consisted of 344 Prathom Suksa 4 Students in Chiang Rai Primary Education Service Area Office 2. The instruments werea deficiency survey form,a diagnostic test and an efficiency evaluation form.

            1.The results of an analysis of wrong answer and deficiency from the test consisting of guessing the answers, the multiplication are mistakes on reading the questions, mistakes on addition, missing on carrying the number, incomplete number of multiplication, switching the symbols between multiplication and division

wrong practice on multiplication table, switching the multiplication results, answering by the questions, and the division are mistakes on reading the questions, mistakes on addition, missing on carrying the number, incomplete number of multiplication, to be disregarded, mistakes on symbol, answering by the questions, putting the answer bya keynumber, putting the division number and switching the multiplication and the division symbols. And The results of an analysis of the deficiency of the constructed test testing by a computer program showed that the most deficiency found in the first school were the mistakes on reading the questions, mistakes on the multiplication table, wrong deduction, and guessing the answers. With regard to the second school, the most deficiency found were guessing the answers, switching the multiplication results, incomplete number of multiplication, mistakes on reading the questions, mistakes on addition, mistakes on the mathematics’ symbols, wrong practice on multiplication table, mistakes on deduction, and answering by the questions.With regard to the third school, the most deficiency found were switching the multiplication and the division symbols, mistakes on reading the questions, answering by the questions, wrong practice on multiplication table, and mistakes on the mathematics’ symbols, in respectively.

1. The difficulty value and discrimination value of these two diagnostic tests were ranged from0.24-0.69 and 0.22-0.82, in respectively. And The discrimination value on the multiple choices of these two diagnostic tests were ranged from0.18 -0.64
2. The basic statistics of the diagnostic test and the reliability value of the diagnostic test on the multiplication were 32.63 and its deviation value was 13.028 and the division was 30.31 and its  standard deviation was 9.704 and its reliability value was ranged from 0.824 – 0.905.

            4.  Overall, the evaluation of the efficiency of the diagnostic test by computer program in the mathematics on the multiplication and division for Prathom Suksa 4 Students was at a good level or at 3.91 (=3.91,SD=0.78). With regard to each aspect, it showed that the Security Test was 4.06 ( =4.06, SD=0.74), the Performance Testwas at 4.03 (=4.03, SD=0.85) and the Usability Test was at 3.91 (=3.91, SD=0.37), in respectively.
