Abstract
The ability of mathematical representation is a crucial aspect in learning mathematics that reflects students ' conceptual understanding, but in reality this ability is still relatively low. This study was conducted to develop electronic worksheets learners (E-LKPD) assisted Infogram platform that is valid, practical, and effective in improving students ' mathematical representation skills on the topic of data presentation. The method used is research and Development (Research and Development) with ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) involving seventh grade students at SMPN 7 Madiun as test subjects. Data collection was carried out through instruments including expert validation sheets, student response questionnaires, and mathematical representation test questions. Data analysis techniques used in this study are adapted to the research instruments, namely analysis of the results of media validation, response questionnaires and mathematical representation test questions. The results showed that e-LKPD assisted by Infogram has a combined validity rate of 88.33%, with the validation details of the material expert reaching 91.67% while the media expert at 85%, so it is categorized as very valid. The level of practicality of E-LKPD is shown through the responses of students with a percentage of 77.5% in limited trials and 84.9% in field trials, both of which have exceeded the minimum limit of 70%. From the aspect of effectiveness, there is an increase in students ' mathematical representation skills, with a percentage of effectiveness of 65.36% (n-Gain score 0.65) in limited trials and 77.49% (n-Gain score 0.77) in field trials. The results show that e-LKPD assisted by Infogram is able to meet valid, practical, and effective criteria, and can be used as a learning medium in developing students mathematical representation skills in data presentation materials.
