Guided Learning
Grokkoli guides learners through the K-4 math curriculum with socratic explanations, practice sessions that generalize the explanations, and reinforcement activities. Grokkoli will fast forward the learner through curriculum they find easy, and slow down when the learner is challenged.
Troubleshoot
Grokkoli breaks down incorrectly answered questions into simpler questions that build back up to the original problem
Reinforce
Grokkoli continually reinforces new learning and incorrect answers over several months to develop long term memories and understanding
Monitor & Remediate
Grokkoli tracks skills over time. Whenever a skill starts to degrade, Grokkoli introduces remediation material to strengthen the skill, and then reinforce it over the next month
