A mathematics teacher is requesting approval to attend in-service courses at SUNY Stony Brook to earn continuing education credits. The courses consist of lectures given by visiting scientists on topics in geology, astronomy, physics, and biology. Each lecture is followed by demonstrations in the research lab or observatory. The teacher has found the lectures provide new ideas that can be used in teaching mathematics, as the topics make use of trigonometric functions, conic sections, differential equations, and regression models. The teacher proposes attending eight lectures over the coming semester.
