Abstract

Assessment of understanding the concept of physics is done using a three-level multiple choice test. The aim is to measure understanding of the concept, the reasons underlying the determination of the measured concept and the confidence in confirming the relationship between the truth of concept knowledge and reason for answering. The construct of the item involves multi representations (verbal, formal, graphic, and numeric) by connecting two representations in one item. The development of the problem considers three validities, namely content, construct and user validity. Test reliability uses the Cronbach alpha formula. The results showed that the content validity considered by the validator had fulfilled the validity requirements according to the proposed method. Content validity reviews the correlation between the concept content of one representation and other relevant or interrelated concept representations. Validity from the user considers the empirical understanding between the representation of concept components assessed and the representation of reasons relevant to improvements in terms of language and content correlation understanding. Data from each item can be used to trace whether there is a misunderstanding concept or the presence of alternative concepts
