| Abstract | The purposes of this study were to develop an instrument for evaluation of mathematics process skills, and confirm its validity. The samples of this study consisted of 180 Grade 2 students under the Office of the Northern Region Education Service Area in Thailand, selected by purposive sampling technique. The instrument used in this research was the mathematics process skills test. Data were analyzed using index of validity item-objective congruence, difficulty, discrimination, reliability and G-Coefficient.The results of this research indicate that: 1) The researcher created 3 sets of mathematical process skills tests for grade 2 students including 12 questions about subjective mathematical process skills. 2) The quality of the instrument for evaluation of mathematics process skills of grade 2 students has content validity of questions at .80-1.00, with content validity criterion at .60-1.00, difficulty scale at .31-.66, discrimination scale at .31-.71, and reliability at .70-.72. In addition, the G-Coefficient for relative decision was .89 and G-Coefficient for absolute decision was .87. |
