Abstract

Diagnostic test instruments used to detect students’ mathematical representation abilities and adjusted to the main principles of mathematical representation abilities, is students can determine the right equation according to the problem and operationalize mathematical equations to solve problems. This research aims to disseminate valid, reliable, and effective diagnostic test instruments for use in physics learning, especially to diagnose mathematical representation abilities. The assessment is based on the results of developing an online web-assisted student’s mathematical representation ability instrument. This research uses the Research and Development (R&D) method which is carried out by taking samples from several high schools in the Bantul Regency. The product was applied to 63 students from two schools in Bantul Regency, Special Region of Yogyakarta with the Cluster Random Sampling (Area Sampling) technique. The development model in this research is the 4D model. The 4D model combined with Oriondo & Dallo-Antonio is implemented through the Define, Design, Develop and Disseminate stages. The research results are (1) the dissemination results of valid diagnostic test instruments to diagnose the mathematical representation ability with V-Aiken coefficient of 0.86 to 1, and reliability can be categorized as “Excellent”, (2) The results of the dissemination to determine the profile of students’ abilities can be categorized “Medium” in terms of the student ability distributions, and (3) the practicality level of the PhysDTRA product assessment was categorized as “Very Good” according to the assessment by the teacher and student responses.
