This digest contains four sections that discuss the following broad principles that offer a framework to teachers for thinking about how technology can support their instruction: (1) learning occurs in context, including ways that technology can facilitate learning by providing real world contexts that engage learners in solving complex problems, and computer simulations and computer-based microworlds that offer contexts for learners to explore and understand complex phenomena in a variety of subject areas; (2) learning is active, including the use of brainstorming, concept mapping, or visualization software, as well as simulations that enable learners to experiment with modeling complex ideas; (3) learning is social, including software that supports a networked, multimedia environment in which students collaborate on learning activities; and (4) learning is reflective, including technologies that promote communication within and outside the classroom, making it easier for feedback, reflection, and revision to occur.
