Stochastic misconceptions of pre-service teachers.
Abstract
Analyzing explanations from 108 participants on a probability and statistics assessment, this study examined the use of two stochastic misconceptions by pre-service K-8 teachers. Representativeness heuristics were used more often when the problem was set in a social context rather than a traditional mathematical setting. Although some participants used representativeness to guide them to a correct answer, most participants were led astray by this heuristic. The majority of the participants did not realize that a conjunction is less probable than either of its constituent parts.
