BrainTrax
"...Our materials are written for the struggling student. We put the concepts in language they can understand. We also use this navigation tool (the Brain) because it associates math concepts for the student. For whatever reason, it appears that our system works, and makes a difference in the student success rate (in lower level math courses, anyway) at our university... Additionally, we have determined that students who use our system in junior-high and senior-high level algebra instruction can also benefit significantly from using the BrainTrax System."
Sections include: Algebra ; Trigonometry ; Calculus I ; Calculus II.
