MyPedia is an integrated, multi-subject system of learning for early and late elementary schools. Developed initially for modern aspiring private schools in India, it aims to support measurable improvement in learners' thinking skills. Each lesson in MyPedia is built on the 5i model of instruction, which structures the learning process into five phases: inception, ideation, inculcation, inscription, and inquisition. As students cycle through these phases, they explore novel questions and examples, apply their developing knowledge and skills, and receive feedback on their learning. For this study, local expert consultants observed teachers and students using MyPedia in typical private schools across India. As well as these classroom observations, this study also analyzed student achievement test scores and the results of teacher and parent surveys. The results of this study suggest that the schools, teachers, and learners MyPedia is designed for, both enjoy MyPedia and are able to use it effectively. Teachers' confidence in teaching with MyPedia increased each quarter from 2017 to 2018. Averaged across classrooms, ratings for MyPedia teaching quality and expected impact on learning also increased over this period. Higher observed MyPedia teaching quality and expected impact ratings are associated with better student test scores. Teachers and parents also expressed high opinions of MyPedia in both 2017 and 2018. [For the summary report, "MyPedia - India. Product Efficacy Report Summary," see ED609289.]
