Virtual Mathematics Laboratory Based on Cognitive Load Theory

Teachers need high levels of creativity and innovation to deliver subject matter during this period digital learning. Literacy numeracy skills are top priorities in schools, mathematics is very relevant for the acceleration literacy development. The goal study was develop a virtual math lab based on cognitive load theory improve skills. ADDIE development model used, consisting stages analysis, design, development, implementation evaluation. Data were obtained needs complete mathematical learning medium that would be accessible fun. design carried out using Drag Drop app builder software. In next stage, framework implemented with builder. validation results showed 80% teaching materials accordance school’s curriculum; categorized as dynamic, remaining 20% identified needing synchronization between videos displayed level attractiveness interactivity lab. According results, modules laboratory developed valid suitable use.
