The Summer Academy program has been in the planning stage for several months and many details have yet to be worked out, such as what classes will be taught at the summer program and who will teach them.

But Katherine K. Merseth, a senior lecturer on education who runs the GSE's Teacher Education Program, said she hopes to begin selecting Cambridge public school teachers to participate in the Summer Academy soon.

Merseth said student-teachers will teach for two hours each morning, working in teams of four with an experienced Cambridge teacher. Then they will review with the teacher how that morning's class went and, later in the day, will take coursework at GSE.

"It's a morning of on-the-line, doing the work and then an opportunity to reflect on that work and then an afternoon of taking classes that make the morning more effective," she said.

The Cambridge teachers--10 of whom Merseth will hire to participate in the Summer Academy--will be paid equally for their work with CRLS students and for their training time with the GSE students, with money for both parts coming from Harvard's share of the financing.

Cambridge school officials said the plan, which was developed jointly by Merseth at the GSE and administrators at CRLS, is targeted at students who had low scores on the battery of Massachusetts Comprehensive Assessment System (MCAS) tests last year, as well as students who simply want to take more classes.

The Harvard-Cambridge Summer Academy would also extend the existing four-week CRLS summer school program by adding an extra week and by holding classes five days a week, not four.
