Middlesex Community College has received a $490,000 Massachusetts Skills Capital Grant to improve science, technology, engineering, and math classrooms and programs. The college will use it to provide updated equipment — including new computers, work stations, projectors, servers, regular and 3-D printers, and wiring and router updates — in five computer science and four engineering and computer-aided design classrooms on its Bedford and Lowell campuses. Governor Charlie Baker’s administration awarded grants to 32 vocational schools, community colleges, and traditional public high schools. Funding will be used to purchase vocational technical equipment and expand skills-training programs for careers in growing industries. “Having access to optimal learning environments and equipment will ensure our graduates are better prepared to meet the needs of employers in high-demand STEM fields,’’ said Kathleen Sweeney, the school’s dean for those fields.
