Teachers...."Even with both of these expensive efforts, it still will not be able to fill the vacancies."

Then maybe it's about time WE adapt and change the teaching model?  My kid had 4 years of difficulty in math UNTIL she had to take this as a bonehead course at UH West.  Imagine how it must have felt for him, to have tears in his eyes when he announced..."I finally.."get it".  THIS also would have worked for me AND a huge segment of our student population, alleviating the NEED for today's antiquated delivery of education.
