Properly integrated technology can increase student learning in areas such as motivation, collaborative learning, critical thinking, and problem solving. Some techniques that have been found to work in education include: identifying similarities and differences; summarizing and note taking; reinforcing effort and providing recognition; assigning homework and practice; utilizing graphic representations of concepts; cooperative learning; providing objectives and feedback; generating and testing hypotheses; providing cues and questions; and using advanced organizers. Technology-rich environments can also be effective for at-risk students, and can motivate students to stay in school and hopefully lessen the achievement gap.
