In the era of the fourth industrial revolution, productive thinking skills are in high demand. Creative thinking, critical thinking, and independent learning are all part of productive thinking skills. A person’s ability to solve a problem with various alternatives can be measured in a range of ways, and productive thinking is linked to these abilities. Wolfram Mathematica is a cutting-edge technology that can be used to solve and visualize a wide range of mathematical problems. The purpose of this study was to develop a multiple representation of calculus with Mathematica (MRC-Math) learning tool to improve students’ productive thinking skills. After developing the MRC-Math learning tool, the experts validated the device. Based on the results of the validation, several improvements were made to the learning device, and then the tool was re-validated. The final validation result showed that the MRC-Math learning tool has a high level of validity.
