Pengembangan Computer Based Diagnostic Multirepresentation Assessment pada Materi Arus Searah untuk Peserta Didik SMA

Abstract

This research aims to: (1) Generate the construction design of assessment instruments to measure multirepresentation in direct current topic; (2) Produce high-quality assessment instruments to measure multirepresentation abilities in direct current topc; (3) Identify the profile of multirepresentation abilities in direct current topic possessed by high school students. This research follows a 4D development model. Data collection involved validating questionnaires with experts and practitioners, as well as distributing instruments to 250 students as trial subjects and 254 students as measurement subjects. The results of this research indicate that: (1) The construction of multirepresentation ability assessment instruments consists of indicators of verbal representation, symbol representation, mathematical representation, and graphical representation; (2) The assessment instruments for multirepresentation abilities have good quality; (3) The multirepresentation abilities of students in direct current topic fall into the moderate category. The most mastered representation is mathematical representation, while the least mastered representation is graphical representation.
