Proposal Summary•Motivation
• Incoming barriers• Number concept• Number facts
• Outgoing barriers• Computation• Procedural automaticity
•Intended outcome• Develop automaticity through deliberate practice
• Goal: schema automation• Support: Cognitive Load Theory

Intended Outcome: Schema Automation
• Cognitive Load Theory– Working memory is limited– Intrinsic, germane, and extraneous loads– Cognitive overload– Automated schemas– Early versus later stages of learning
Why is schema automation desirable?

Deliberate Practice
• Students’ practice has actually improved their performance.
• Practice is within the student’s ability level.• Timely and descriptive feedback.• Repeated opportunities to practice a task
through practicing other tasks like it

MethodologyCreation Cycle
1. Coded a usable version2. Implemented in classroom3. Revised code based on usage data
Updates for Usability• Accessible from any Nspire document• Parsing user input for flexiblity
Changes to Program Structures• Narrowed focus of ysolver()• Created separate programs for linear forms
Additional Features• Generators

•3 programs with levels• 1-variable linear equations• 2-variable linear equations• Systems of 2-variable linear equations• Teacher documentation for usage
•3 programs for linear forms• Slope-intercept form• Point-slope form• Standard form• Worksheets for student usage
•Generator for most programs

Motivation: Classroom Needs
Student Needs– Incoming barriers
• Number concept• Number facts
– Outgoing barriers• Computation• Procedural
Teacher Response– Quantity of practice– Quality of practice– Feedback– Individualization
PRACTICE!!! Shift focus to GERMANE load.
