Modeling Quadratic Functions in the Schoolyard

EasyChair Preprint 3439

Abstract

Teaching in the schoolyard using digital technologies is one of many components for the structure of mathematics lessons. One examples from analysis lessons which has been tested in real school lessons will be presented in this paper: a basketball throw in the context of quadratic functions. 15-year old pupils experience haptic mathematics, the functional graph arises using transparencies and pins, the functional equation can be developed and tasks can be solved in the fields of sports application. Pupils use their own smartphones (bring your own device) in this lesson: They film their activities and collect and evaluate the measured data of their video. Furthermore, this paper describes varieties of conducting this lesson and one possibility of an interdisciplinary teaching approach in physics. The pupils compare the trajectory as a ballistic curve with a parabola of the quadratic function and they calculate the initial velocity.

Keyphrases: Initial Velocity, basketball throw, quadratic function, schoolyard
