In the present set of experiments, we systematically examined the processes that occur while reading texts designed to refute and explain commonsense beliefs that reside in readers' long-term memory. In Experiment 1 (n = 36), providing readers with a refutation-plus-explanation of a commonsense belief was sufficient to significantly reduce…

This study examined how science teachers' knowledge of research methods, neuroscience and drug addiction changed through their participation in a 5-day summer science institute. The data for this study evolved from a four-year NIH funded science education project called Addiction Research and Investigation for Science Educators (ARISE). Findings…

This study investigated the effects of two different true-false questions on memory awareness and long-term retention of knowledge. Participants took four subsequent knowledge tests on curriculum learning material that they studied at different retention intervals prior to the start of this study (i.e. prior to the first test). At the first and…

A total of 271 early childhood professionals completed pre- and post training knowledge assessments in True-False only (TF) or True-False with "unsure" option formats (TFU). In Study 1, only TFU format was used. In Study 2, participants were randomly assigned to TF or TFU formats. Responses which were initially "unsure" were…

Confidence Weighting (CW), after Ebel, and Multiple Responding (MR), after Coombs, are compared empirically to determine which improved test reliability more in the case of a course pretest derived from the final examination. It was hypothesized that MR, which purportedly measures partial knowledge, would be more effective than CW, which measures…
