Students returned to classrooms yesterday in Tucson and at the University of Bridgeport in Connecticut, but formal education for more than 200,000 others was stymied by teacher's strikes in eight other states.

On a standup vote Sunday night in Tucson, teachers gave nearly unanimous approval to a compromise package that contains a 6.4 percent pay raise and a two-year no-strike clause.

Some 8,000 college students at Bridgeport returned to the books in an uneasy truce between the board and teachers, who began their job action Sept. 22. Attempts to resolve remaining issues will be made through nonbinding arbitration.

Striking teachers in the Columbus, Ohio, suburb of Whitehall returned to work while walkouts continued in five other districts including Cleveland, where school employes have been on strike, more than a month. About 200 teachers in Whitehall, who had been on strike for a week, agreed to a new contract Sunday night.

In Memphis, leaders of the teachers' union recommended rejection of the school board's latest wage offer and warned of the "strong possibility" of a strike by its 5,500 members this week.

Strikes also were reported in Indiana, Maine, Michigan, New Jersey, New York, and Pennsylvania.
