Assessing Programmable Logic Controller Skill of Electrical Engineering Student

摘要

Measurements in education can not be separated from the measurement of the students' capabilities of educator candidates. The ability of prospective students can be measured by using a measuring instrument (test). A lecturer should know the scoring theory used to measure the ability of his students. Scoring theory includes classical test theory and modern test theory. Each of these test theories has advantages and disadvantages. Test theory developed in Indonesia today is a classic test theory. Modern test theory has developed in some advanced countries. The progress of information technology has had an impact in the development of modern test theory. The process of calculating the scores of test takers using modern test theory is more complex than using classical tests. in this study, the test items of programmable logic controller (PLC) of electrical engineering students were analyzed using classical test theory approach and grain response theory. The grain difficulty statistics on the classical test theory is the p value, which is calculated based on the proportion of students who correctly answer a test item. Parameter b is a location parameter, indicating the position of the grain characteristic curve In relation to the scale of ability. The correlation between the values of b and p is -0,980 of the 38 PLC test items, there are 1 non-fit test items based on the Rasch model. Parameter b has a starting value of -3,07 to 4,24. The parameter of p grain has a value from 0,03 to 0,97.
