Variations of College Algebra instructors’ presentations of the mathematics: The case of solving quadratic inequalities
Page: 1593
The mathematical content presented during instruction has been shown to have an effect on studentachievement. To investigate the content presented by instructors during College Algebrainstruction, the Mathematical Quality of Instruction (MQI) observation protocol was applied tovideo recordings featuring instructors’ presentations of examples of solving quadraticinequalities. Wide variation was observed in the solution methods chosen by instructors and in therationale provided for choosing a particular procedure. This poster summarizes the variation inthe mathematics that was observed and the ability of the MQI protocol to capture this variation.Key words:
