การพัฒนาแบบวัดจิตวิทยาศาสตร์สำหรับนักเรียนมัธยมศึกษาตอนต้นในสามจังหวัดชายแดนใต้

Abstract

The purposes of this research were 1) to construct of scientific mind scale for Junior High School Students in the three southern border provinces 2) to verify the quality by the Classical Test Theory (CTT) and Item Response Theory (IRT). The sample were 675 students selected by three-stage random sampling technique. The students selected were studying in junior high school under the jurisdiction of the Secondary Education Office Service Area and Office of the Private Education in the three southern border provinces. The measurement scale designed was performed via the Classical Test Theory by content validity, discrimination, and reliability with Cronbach’ alpha coefficient and the quality of the measurement scale by Item Response Theory. and parameter testing was accomplished by confirmatory factor analysis (CFA), discriminant and difficulty, and test information was conducted via Grade Response Model (GRM). The findings were. 1. The Measurement Scientific Mind Scale for Junior High School Students in the Three Southern Border Provinces composed 10 components including 1) curiosity 2) honesty 3) patience, strive and persevere 4) orderliness and prudence 5) responsibility 6) initiative 7) rationality 8) generosity 9) cooperation and 10) good attitude toward science. Each component has 4 indicative behaviors, a total of 40 indicative behaviors. During the construction of the measurement, there were quality checks and improvements until a total of 40 item. 2. The quality measurement scale. Content validity of the scale range from 0.71-1.00, t-test was used to analyze the discrimination. The reliability was 0.893. using by confirmatory factor found Scientific Mind were unmistakable when examining the quality of the Grade Response Model (GRM). The slope parameter(α) is between 0.58-1.45 and the difficulty value The threshold value of each item (β) is the lowest order value, and reliability is 0.9216
