This poster reports on a study that compared three types of summaries at the end of natural-language tutorial dialogues and a no-dialogue control, to determine which type of summary, if any, best predicted learning gains. Although we found no significant differences between conditions, analyses of gender differences indicate that female students…

Although restating part of a student's correct response correlates with learning and various types of restatements have been incorporated into tutorial dialogue systems, this tactic has not been tested in isolation to determine if it causally contributes to learning. When we explored the effect of tutor restatements that support inference on…

Supplemental Instruction (SI) has widely been used in university classrooms around the world. However, many obstacles face SI -- including low student attendance, lack of faculty support, and recognition of today's online generation. This research helps to fill the gap in SI by posing to solve the problems mentioned above by extending SI into the…

The starting point for this study was the resistant nature of prior knowledge in conceptual change from natural numbers to rational numbers observed in our previous study. Thus, in this study the effects of deliberately teaching the abstraction of the density of numbers on the number line was tested in a quasi-experimental study at the beginning…

Studied prior knowledge as a mediator of effectiveness of the elaborative interrogation strategy for 50 male and 50 female undergraduates in a learning task. The elaborative interpretation group had significantly greater matching scores on an associative memory test for animal information than the control group only for familiar animals. (SLD)
