A tentative fuzzy assessment of the quality of teaching and opportunities to learn mathematics in a classroom discussion

摘要

We study classroom discussions to obtain a fuzzy summary of the quality of teaching and opportunities to learn mathematics created in whole-class settings. We consider the ten rubrics of the Instructional Quality Assessment and make a fuzzy interpretation of this tool. We selected two problems of proportionality and collected data from forty-nine students. We make a statistical analysis of their written responses to the tool and consider their perceptions and feelings about the lesson. This analysis provided information about what rubrics are considered relevant to compute the fuzzy summary.
