Highlights include inquiry learning; abilities of learners; and the integration of technology within classroom…

Two alternative representations for the concept of common multiples are presented. These representations can be modeled on or off the computer. (PK)

Technology can be useful in physics classrooms, though teachers must be careful not to let technology remove students from first-hand experiences with nature through observation and experimentation. The paper examines how to enhance physics instruction using computers as graphing tools, for data collection, and as real-world simulators. (SM)
