Social facilitation of drinking of a partially satiated duckling

Water-deprived and nondeprived ducklings were reintroduced to a flock companion which had been allowed to partially satiate itself after 3 h of water deprivation. The drinking and sieving behavior of the partially satiated “reactor” bird was immediately increased above that of similar birds left on their own. However, whether or not the introduced “actor” ducklings were deprived had no consequences for the drinking response of the reactor above that obtained by their introduction. The number of companions introduced also failed to have any effect other than that obtained by their introduction. The increase in sieving was greater when deprived, rather than nondeprived, actors were introduced. These results were discussed in relation to the motivational aspects of sieving behavior and the mechanism of social facilitation.     

Preschool Teachers' Perceptions about Conflict Resolution, Autonomy, and the Group in Four Countries: United States, Colombia, El Salvador, and Taiwan

Preschool teachers (N = 160) in four countries (U.S., Colombia, El Salvador, and Taiwan) were surveyed about their views of conflict resolutions for moral and social-conventional conflicts, providing choice in the classroom (autonomy), maintaining a sense of the group, and general pedagogical aims of early childhood education. The findings revealed cultural similarities regarding conflict resolution intervention techniques and providing choice in the classroom. Cultural differences were found for maintaining the group and encouraging traditional group values. The items regarding the general pedagogical aims revealed a mixture of cultural differences and similarities. The results have implications for formulating generalizable goals for facilitating social and moral development in early childhood development and education.     

A Study on the Impact of GPA on Perceived Improvement of Higher‐Order Cognitive Skills*

Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes.     

Comparisons of beliefs about the nature of knowledge and learning among postsecondary students

The purpose of this study is to assess postsecondary students' beliefs about the nature of knowledge and learning, or epistemological beliefs. Comparisons were made between junior college students and university students and between technological science majors and social science majors on their degree of belief in simple knowledge, certain knowledge, innate ability, and quick learning. Junior college students were more likely to believe in simple, certain knowledge, and quick learning. University students were more likely to believe in innate ability. Technological science majors were more likely to believe in quick learning. Background variables, such as age, gender, and parental education, also contributed to differences between groups. Two-year institutions, as well as four-year institutions, might want to consider students' epistemological beliefs as possible factors affecting academic performance, attrition rate, and transfer difficulties.     

知识建构共同体及其支撑环境

面对知识社会的挑战,我们需要将学校改造成为知识建构共同体。知识建构共同体是以思想的形成和持续改进为关注点的团体,其成员通过建构性的互动过程发展对于共同体有价值的思想。为了支持和促进知识建构共同体,本课题组研制了CSILE/知识论坛系统。本文对上述理论观点、技术系统以及有关的实验研究结果做了简要介绍。
