So far, enrichment learning has been conducted by only giving practice test without using supporting media. Therefore, students on enrichment class feel bored because they are only given working exercises and discuss the solutions. Based on the problem, this research aims to develop calculator-assisted enrichment learning tool to facilitate students, mainly the special intelligent students who take enrichment learning to obtain new knowledge and experience in using calculators. This research was Research and Development of Plomp model. Research subjects consisted of 33 students of VIII grade of Junior High Schools in Pasuruan. Validation instruments consisted of validation sheets. Practical assessment instrument consisted of an assessment sheet by teacher and students, and observation sheet of learning implementation. Effectiveness evaluation instrument was student's final test sheet. Analysis techniques of enrichment learning tools data were classified into two, qualitative and quantitative. Based on result, math enrichment learning tools meet valid criteria by successive scores of 119.5, 95, and 48.5 with good classification. Then, the tools meet practical criteria in terms of assessments by teachers and students by 119 and 76.64 with very good classification. Learning implementation achieves a percentage of 85% and student mastery achieves 95.45%. Therefore, a calculator-assisted enrichment learning tool appropriate to be used as one of the learning tools that has fulfilled the valid, practical, and effective criteria. © 2020 Little Lion Scientific.
