Computers frequently are not utilized adequately or optimally in classrooms. However, selected principles of learning are applicable to computer and software usage. They include: (1) meaningful and achievable exercises; (2) sequential learning; and (3) purposeful content. Learner interest, motivation, and balance among objectives are significant considerations in computer instruction. The types of software selected for student use should reflect definite social studies goals, and diverse kinds of software programs, based on established objectives, need to be utilized in ongoing lessons and units. Those programs include: (1) drill and practice; (2) tutorials; (3) diagnosis and remediation; (4) simulations; and (5) games. Different types of educational philosophies, such as experimentalism, idealism, realism, and existentialism, may be used in computerized classroom settings. Computers can be successfully used with both a behavioristic approach, stressing a logical, sequenced curriculum, or a humanistic approach, emphasizing student-teacher planning and an open curriculum.
