Minor Thesis TitleDevelopment of Mathematical Problem-Solving Skills Test for Upper Elementary School Students�Author Miss Naris SrisawatMajor Program Research And EvaluationAcademic Year 2023ABSTRACTThis research aimed to (1) develop and examine content validity of a mathematical problem-solving test for upper primary school students, and (2) examine the quality of the test in terms of inter-rater reliability, difficulty, discrimination, and concurrent validity. Sample consisted of 60 upper primary school students from Chumchonbansako School, Narathiwat Primary Educational Service Area Office 1, in the academic year 2023. Stratified random sampling was used to select the participants. The developed test consisted of five open-ended questions with analytic scoring rubrics based on Polya's problem-solving procedures. The results showed that:1.The item objective congruence (IOC) for each item was greater than .7, indicating that the items were relevant to the content domain. The results of the inter-rater reliability analysis showed that the scoring was consistent and accurate between the two raters, rxy=.99, p??????????????????????????????????????????????????????? ???????????????????????????????????�??????????????????? ?????????????????????????????????????????????? 2566??????????????????????????????????????????? 1) ????????????????????????????????????????????????????????????????????????????????????????????????????????????? ??? 2) ??????????????????????????????????????????????????????????????????????????????????? ??????????? ????????????? ????????????????? ??????????????????????????????????????????? ????????????????????? ?????????????????????????????????????????????????? ??? 1 ??????????????? 2566 ????? 60 ?? ?????????????????????????? ??????????????????????????????????????????????????????? 5 ??? ???????????????????????????????????????????????????????????????????? ?????????????????? ?????1.????????????????????????????????????? ?????????????????????????????????????????????????????????????? 0.7 ??????????????????????????????????????????????????????????????????????????
