This episode focuses on the importance of personalizing learning by using an acronym called SYNAPSE. The "P" in SYNAPSE represents "personalize," which is a key strategy to make learning more engaging and effective. The episode suggests that by connecting learning to one's own life experiences, character strengths, and cultural background, students can boost their motivation, memory, and overall u...

This episode describes a learning strategy which encourages learners to connect new ideas to their existing knowledge base. The strategy involves creating concept maps, which are visual representations of relationships between concepts. By connecting new information to familiar concepts, learners can improve comprehension, memorization, and retention. It advocates for incorporating personal experi...

 "N is for Narrate" introduces Narrate, a study strategy that helps students overcome the feeling of being overwhelmed by new material. The method encourages students to transform complex topics into narratives by exploring key concepts, identifying actors and their relationships, and pinpointing crucial turning points. The process encourages students to think critically and creatively by drawing...

This is the second part in the series of SYNAPSE.  It argues that learning is a skill that can be developed through practice, and it encourages students to adopt a "growth mindset," which involves believing that they can improve their learning abilities. The episode highlights the importance of saying "Yes!" to affirm this belief and provides several strategies for students to implement in order t...

Reduce the process to its core elements, managing attention, complexity, cognitive load, and stress. SYNAPSE was created by Christine Marshall. Read more about her work here.
