Maryland Gov. William Donald Schaefer will travel to the Boston area Tuesday to learn more about day care programs, the governor's aides announced yesterday.

Schaefer and his entourage plan to visit the Stride Rite Children's Center in Cambridge, which has gained national recognition as a successful corporate day care program.

The Democratic governor also will tour a private, nonprofit child care resource center and meet with Massachusetts Gov. Michael S. Dukakis, a Democratic presidential candidate.

"There is no greater issue facing Maryland and our nation than day care," Schaefer said. "I will help organize and motivate others to join in a partnership to make affordable, quality day care available to our work force."

The Schaefer administration's 1988 legislative package promises "substantial" additional funds to subsidize the costs of day care for children from low-income Maryland families.

The governor also said he wants to establish a state child care coordinator to "coordinate policy development and promote day care as a business resource."

Schaefer also is asking the General Assembly to create a direct loan fund for day care facilities, and to expand an existing day care facilities loan guarantee fund.

Statistics show that in 1986 about 75 percent of Maryland mothers with children younger than 6 were in the work force. However, there were only 6,789 regulated family day care providers and 1,348 licensed center-based programs to care for the approximately 73,300 children in need of day care.
