An extensive report from the Ohio Education Research Center . E-schools are not successful. More dropouts, poor performance with similar demographics. No magic bullet/solution or excuse was determined. It is a failed one billion experiment.
A very thorough report. The conclusion:
E-school students’ performance
on standardized tests are dramatically lower, especially for
math, compared to those
students who attend a brick-and-mortar school. Test scores
plummet the year a student
transitions to an e-school. E-school students’ scores see
incremental increases in the
subsequent years. However, it is important to note, that despite
subsequent increases their
scores remain below the scores they received prior to entering an
e-school.
What is the cost?
