Chernoff, Egan J.; Mamolo, Ami; Zazkis, Rina – EURASIA Journal of Mathematics, Science & Technology Education, 2016
By focusing on a particular alteration of the comparative likelihood task, this study contributes to research on teachers' understanding of probability. Our novel task presented prospective teachers with multinomial, contextualized sequences and asked them to identify which was least likely. Results demonstrate that determinants of…

Chernoff, Egan J.; Mamolo, Ami – Canadian Journal of Science, Mathematics and Technology Education, 2015
The objective of this article is to contribute to research on teachers' probabilistic knowledge and reasoning. To meet this objective, prospective mathematics teachers were presented coin flip sequences and were asked to determine and explain which of the sequences was least likely to occur. This research suggests that certain individuals, when…

Chernoff, Egan J.; Russell, Gale L. – North American Chapter of the International Group for the Psychology of Mathematics Education, 2013
The objective of this article is to contribute to the documented dearth of research on teachers' probabilistic knowledge. Prospective teachers of elementary school mathematics were asked to identify which result from five flips of a fair coin was least likely to occur. Participants, instead of being presented with sequences, were presented with…

Chernoff, Egan J.; Russell, Gale L. – North American Chapter of the International Group for the Psychology of Mathematics Education, 2011
The main objective of this article is to contribute to the limited research on teachers' knowledge of probability. In order to meet this objective, we presented prospective mathematics teachers with a variation of a well known task and asked them to determine which of five possible coin flip sequences was least likely to occur. To analyze…
