One of the most comprehensive ventures was the restoration and transformation of Boston's eighteenth century Faneuil Hall and the Quincy Market, designed in 1824. This section had fallen on hard times, but beginning with the construction of a new city hall immediately adjacent, it has returned to life with the intelligent reuse of these fine old buildings under the design leadership of Benjamin Thomson. He has provided a marvelous setting for dining, shopping, professional offices, and simply walking.
Butler Square, in Minneapolis, exemplifies major changes in its complex of offices, commercial space, and public amenities carved out of a massive pile designed in 1906 as a hardware warehouse. The exciting interior timber structure of the building was highlighted by cutting light courts through the interior and adding large skylights.

Two things emerge in the study of students’attitudes toward online learning: individual situations impact students’ perceptions of computer-based learning, and students’ varied individual characteristics make it difficult to define their perceptions conclusively. For example, some students have their own computers, while others rely on computer labs. Such variation in computer access can result in attitudinal differences. In addition, the purpose of computer use varies. Distance education courses, for example, use computers in different ways than traditional classrooms, which can also affect students’ perceptions. A wide variety of achievement levels and attitudes exist among both online and traditional learners. Although an illusory “typical learner” exists, a variety of factors, including students’ gender, age, and motivation, could explain different reactions among the student population.
