My Take
I think Lalilo is a great supplement tool in the classroom and at home. It allows teachers to see how the students are doing live. The ability to assign lessons to redo is a great way for students to get immediate remediation.
How I Use It
My students took the Placement Test, YES there is one now! After the placement test, they began their lessons. After one week of the students working 15-25 minutes 3-4 times the first week, I reviewed their progress. I, then, assigned each student the lesson I felt they needed to review. We logged in first thing Monday morning and no one commented they had done that lesson. I checked their progress after the lesson and saw a lot of improvement.
