Constructing and Developing the PISA - Like Thai Language Tests

Abstract

This study aimed to develop the PISA-like Thai Language tests. PISA-like Thai Language test papers for eight levels, primary levels 2 - 6 and secondary levels 1 - 3, were constructed and assessed for quality. Test papers were constructed within the framework derived from analysis of learning standards and indicators stated in the B.E. 2551 Basic Education core curriculum of Thailand; each consisted of 45 items. Parallel test papers, 20 copies for each level, were constructed under the same framework and sent to experts, 5 experts per copy, for approval of content validity. The tests then were tried out with students, 100 students per copy. The results were analyzed to see level of difficulty and discrimination. Test items with suitable level of difficulty (.20 ≤ P ≤ .80) and discrimination (r ≥ .20) were chosen and rearranged to make a 45 item test paper, 15 copies for each level. The test papers of all 8 levels, 15 copies per level, were used with 100 students per level to rearrange the test papers and separate each items by pattern of answer. The study showed that the PISA-like Thai Language test items, as approved by experts, were found to be valid in structure. The level of difficulty was between .35 - .78 while the discrimination was between .37 - .45. There are 8 levels of test papers, each class consisted of 15 copied, 675 items.
