The Magnetic Field

The paper presents simulation of the dynamics of a permanent magnet linear actuator with soft magnetic mover and relatively long stroke 60 mm. The simulation is carried out using decoupled approach where the magnetic field problem is solved separately from the electric circuit and mechanical motion problems. The obtained results are compared with experiment. .

The answer to educating gifted and talented students in heterogeneous classrooms may lie, at least partially, in using instructional technology to motivate learning and enrich lessons. This case study explores one aspect of effective instruction for gifted second graders during lessons conducted in their general education classrooms. This chapter summarizes the development and delivery, students' performance and perceptions, and professional implications of an elementary science lesson utilizing interactive whiteboard technology to convey science content and elicit participation. It also emphasizes the importance of teacher educators' modeling the use of interactive whiteboards for the purpose of differentiating instruction in teacher training programs to better prepare future teachers for the diverse learners who will fill their classrooms.
