A model for the analysis of subjects’ causal reasoning is proposed, drawing on de Kleer and Brown's ‘mechanistic mental models’. The purpose of the model is to provide a framework for understanding the possible causal structure of children's and adults’ spontaneous reasoning about the physical world. The model is used to analyse data on students’ understanding of aspects of forces and motion; to reanalyse a protocol of Driver's; and to compare and criticize the models of Andersson and of Rozier. We show how the model can provide a language for describing common‐sense causal thinking. 相似文献

This study examined the effects of extra time on the reading comprehension performance of a heterogeneous group of adults
with reading disabilities. Sixty-four adults participated. A clinic that assesses learning disabilities identified 22 as reading
disabled, and 42 as normal readers. The 64 adults took a reading comprehension test under both timed and untimed conditions.
Other skills measured included vocabulary, word reading, non-word reading, spelling, arithmetic, and short-term memory. Under
timed conditions, there were significant differences between the participants with reading disabilities and the normally achieving
participants. All of the reading disabled participants in the present study benefited from extra time, but the normally achieving
readers performed similarly under the timed and untimed conditions. Further, in the untimed condition, the performance of
the individuals with a less severe reading disability was not significantly different that of the Average readers. The study
suggests that extra time during testing is an appropriate accommodation to help individuals begin to compensate for reading
disabilities. 相似文献
