Developing Understanding of Statistical Variation: Secondary Statistics Teachers' Perceptions and Recollections of Learning Factors.

This retrospective phenomenological study investigates activities and actions identified by secondary statistics teachers who exhibit robust understandings of variation as deepening their understandings of statistical variation. Using phenomenological methods and a frame of Mezirow’s transformation theory, analysis revealed learning factors that include their interests in statistics, motivation to encounter and resolve dilemmas, desires to have an overarching content framework, propensities for critical reflection, and actions on opportunities to engage in statistical learning activities and rationale discourse with more knowledgeable others. The extent to which these teachers embrace these opportunities distinguishes them from other teachers. Results from this study provide some basis for formulating hypotheses about secondary teachers’ statistics learning in general by contributing to understanding circumstances that may be conducive to developing deep understandings of statistical content. This study also advances the use of retrospective methods within a theoretical frame for adult learning to investigate teacher learning.
