MIT BLOSSOMS: Blended Learning Open Source Science or Math Studies

Principal Investigator Richard Larson

Co-investigators Daniel Frey , M Murray , Ling Wang


BLOSSOMS video lessons are enriching students' learning experiences in high school classrooms from Brooklyn to Beirut to Bangalore. The Video Library contains over 50 math and science lessons, all freely available to teachers as streaming video and Internet downloads and as DVDs and videotapes.

Visit the BLOSSOMS Video Library anytime to browse and download lessons to use in your classroom. Every lesson is a complete resource that includes video segments, a teacher’s guide, downloadable hand-outs and a list of additional online resources relevant to the topic. We carefully craft each BLOSSOMS lesson to make your classroom come alive. Each 50-minute lesson builds on math and science fundamentals by relating abstract concepts to the real world. The lessons intersperse video instruction with planned exercises that engage students in problem solving and critical thinking, helping students build the kind of gut knowledge that comes from hands-on experience. By guiding students through activities from beginning to end, BLOSSOMS lessons give students a sense of accomplishment and excitement.

While MIT faculty members and partnering educators in Jordan and Pakistan created the first BLOSSOMS lessons, today educators from around the world create and submit BLOSSOMS modules. We welcome you to join our international online community to learn more about our videos and to engage with educators worldwide who are looking for ways to enrich their students' classroom experiences and share their ideas.

During a visit to a rural school in China, BLOSSOMS founders Richard Larson and Elizabeth Murray watched as a videotaped lecture enlivened an otherwise cold, bleak classroom. The teacher paused the lecture from time to time to engage with the class. The interruptions worked, but awkwardly, prompting Larson and Murray to wonder what would happen if they created video lessons that were designed to be interactive. They envisioned video lessons dovetailed with engaging activities for teachers to do with their students.

So inspired, Murray and Larson set out to create BLOSSOMS (Blended Learning Open Source Science or Math Studies), a series of freely available interactive lessons presented in a widely accessible video format. BLOSSOMS video modules supplement the standard curriculum with virtual lessons led by educators from around the world and activities led by local classroom teachers.

The BLOSSOMS project is sponsored at MIT by LINC (Learning International Networks Consortium), a global consortium of educators interested in using distance and e-learning technologies to increase access to quality education worldwide. BLOSSOMS is an “Open Educational Resource,” a web-based collection of materials offered freely and openly for re-use in teaching, learning and research. OERs such as BLOSSOMS help make education a right rather than a privilege by providing schools around the world with access to quality educational tools.
