The Development of Physics 2 Criterion–Referenced Test on Work and Energy for Matthayom Suksa 5 Students

Abstract

            The purposes of the research were : 1) to develop the Physics 2 Criterion-Referenced test on Work and Energy, 2) validate the Physics 2 Criterion-Referenced test on Work and Energy, and 3) determine the cutting point scores of Physics 2 Criterion-Referenced test on Work and Energy. Samples used in the research were 677 for Matthayom Suksa 5 students of the academic year 2017 at schools under the Jurisdiction of the Secondary Education Service Area Office 29. Samples were selected by using multi–stage random sampling. The tests were developed and verified for the content validity by the experts. The first and second tests were to select and develop the tests whereas the third test was to evaluate for the difficulty and discrimination by the B-Index program. Statistical analysis used to analyze the construct validity was Caver’s method, the reliability was Lovett’s method, and the cutting point score was Berk’ s method.

            The research findings were as follows:

1. The Physic 2 Criterion-Referenced test on Work and Energy for students in Mattayom Suksa 5 was a multiple choice with four alternatives choices. The test was divided into four sets, including set one was Work and Power for 25 items, set two was Energy for 22 items, set three was Law of Conservation of Mechanical Energy, and set four was Simple Machine for 10 items.
2. Results on the quality analysis of all four sets of Criterion-Referenced tests were found that the content validity was from 0.57 to 1.00, the discrimination was from 0.21 to 0.84, the difficulty was from 0.22 to 0.76, the construct validity was from 0.80 to 0.89, and the reliability was from 0.74 to 0.84.
3. Results on cutting point scores were found that all four sets of Criterion-Referenced tests had cutting point scores at 13 from 25, 10 from 22, 9 from 20, and 4 from 10, respectively.
