This study aims to investigate about the existence of a graphical facilitation effect on probabilistic reasoning. Measures of undergraduates' performances on problems presented in both verbal-numerical and graphical-pictorial formats have been related to visuo-spatial and numerical prerequisites, to statistical anxiety, to attitudes towards…

The current studies investigated the efficient use of dialogue in intelligent tutoring systems that use natural language interaction. Such dialogues can be relatively time-consuming. This work addresses the question of how much dialogue is needed to produce significant learning gains. In Experiment 1, a full dialogue condition and a read-only…

Fluctuations in problem solving and classroom behaviors during the school day for 43 hyperkinetic intermediate students with attention deficits were examined. Ss were observed with the Stonybrook Observation Code and tested with the Stroop Color-Word Test, Matching Familiar Figures, Porteus Mazes, and Digit Span. Data were collected in…

The compensatory-encoding theory (C-ET) of reading specifies how the efficiency of performance subcomponents affects comprehension under diverse task conditions. It maintains that readers can overcome weak skills through compensatory processes. To test whether C-ET captures more general principles underlying scholastic performance, the authors…

Background: A paradigm shift in educational policy to create problem solvers and critical thinkers produced the games concept approach (GCA) in Singapore's Revised Syllabus for Physical Education (1999). A pilot study (2001) conducted on 11 primary school student teachers (STs) using this approach identified time management and questioning as two…

A within-subjects design was used to compare two instructional methods--explicit timing and interspersing--with 187 second-grade students. Students completed two mathematics word problem assignments under differing conditions. In the explicit timing condition, students were told they would be timed while working long mathematics word problems. In…

Many previous studies have documented the importance of time needed for learning and time spent in learning as parameters of educational achievement. However, most of this research has not considered the different types of tasks students are asked to learn. This study examined differences in student learning rates, amount of information acquired,…

Using the Internet to administer homework allows us to determine if students change their homework habits during a semester and if this change results in an improvement in grades.

This proceedings contains the texts of 14 science education research studies which were presented at the 1983 Western Australia Science Education Conference. They include: "Students' Understanding of Chemical Equilibrium: A Report of Research in Progress" (Patrick J. Garnett, Mark W. Hackling); "Measuring the Learning Environment in…
