Cognitive Load
The amount of mental effort required to process information. Too much cognitive load makes learning harder; too little may not provide enough challenge.
Cognitive Load Theory, developed by John Sweller, explains that our working memory has limited capacity. When information demands exceed this capacity, learning becomes difficult and frustrating. There are three types of cognitive load: intrinsic (the inherent difficulty of the task itself), extraneous (unnecessary complications in how information is presented), and germane (mental effort devoted to understanding and integrating new information). For example, trying to learn long division while also managing confusing notation creates excessive cognitive load. The same concept taught with clear step-by-step visual examples reduces extraneous load and allows working memory to focus on the actual learning (germane load). Good instruction minimizes extraneous load while optimizing germane load - removing distractions and confusing elements while maintaining appropriate challenge. Parents can recognize cognitive overload in their children through signs like frustration, shutdown behavior, or inability to retain information despite effort.
How Grove applies this
Grove carefully manages cognitive load by presenting concepts in digestible pieces, using multi-modal formats (text, dialogue, visuals), and allowing children to control pacing. The dialogue format itself reduces extraneous load by presenting information conversationally rather than through dense text. The system adapts complexity based on the child's responses to maintain optimal challenge.

Working Memory
The cognitive system that temporarily holds and manipulates information while you're processing it. It's like the brain's mental workspace for thinking.
Flow State
Mihaly Csikszentmihalyi's concept describing the state of complete absorption in an activity where challenge and skill are perfectly balanced. Time seems to disappear and the activity is intrinsically rewarding.
Scaffolding
Temporary support provided by a teacher or mentor to help a learner accomplish a task just beyond their current independent ability. The support is gradually reduced as the learner becomes more capable.
Adaptive Learning
A teaching approach where instruction is continuously adjusted based on individual student's performance and needs. The system responds to each learner's unique pace, strengths, and gaps.
