This guide provides suggestions for using technology (i.e., computers and anything that attaches to computers) as instructional tools in environments that support learning. Chapter 1 offers an overview of learning principles based on constructivist theory, including what constructivism offers the classroom, the role of the student, the role of the teacher, and changes in the classroom. Chapter 2 presents activities based on constructivism, without technology, in three learner-centered classrooms, including a story writing group, math estimation exercises, and a trial of Julius Caesar's murders. Chapters 3 and 4 examine ways computers can complement classroom instruction; initial steps for introducing technology into the classroom are provided, and examples of activities that employ several types of applications (word processing, database, spreadsheet, presentation, simulation, Internet, e-mail, and multimedia/hypermedia) are presented. Chapter 5 is a practical compendium of questions, answers, and considerations for introducing technology into the learning environment. A resource section provides more information on technology and constructivist theory. (Contains 30 references.) (AEF)
