This study explored the use of information technology in mathematics instruction. Using students' self-evaluation and interviews as well as observation and checklists as feedback mechanisms, the researcher collected data for four months. Some appropriate instructional methods for teaching mathematics in such a way as to keep the spirit of constructivism alive were developed, methods relying heavily on information technology. Finally, the discussion and suggestions of administrative support, team teaching, proper hardware, teaching time, textbooks, and learning problems could be used as references for teachers in the future implementation.
