Two experiments examined preschool children's ability to draw inferences about numerosity from correspondences between sets. In Experiment I, 3-and 4-year-old children made numerical inferences about a hidden set from their own counts of a corresponding visible set and also from numerical information about that set stated by the experimenter. Experiment 2 contrasted a count condition with a move condition, in which children's attention was not explicitly drawn to the numerosity of the visible set. Again, children were able to make numerical inferences as early as 3 years of age. However, differences between the 2 conditions implicate production deficiencies in young children's use of counting as a problem-solving strategy when they are not explicitly told to count.
This study examines the relationship between two types of preschool programmes and children's creativity performance in Hong Kong context using Torrance TCAM measurement. A pretest-intervention-posttest design was adopted. Post-test results showed that children schooled in the play-oriented preschool, and those in the academic-oriented preschool both improved in creativity scores after inquisitive-play or informed-play were added. Post-test results also showed different gender effects. Finally, the dimensions of TCAM which drive the boys' and girls' gain in creativity scores were identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
