刍议学术期刊的特色、质量、影响力

从概念和功能层面上探讨了学术期刊的特色、质量、影响力：特色主要反映的是办刊人的谋略和手段;质量重在它的学术质量,主要反映的是作者的学术水平;影响力主要反映的是受众对期刊的认同程度。尽管三者各具不同的内涵,但均直接或间接反映了期刊学术质量水平的重要性。所以,学术质量是学术期刊发展的核心内容,是其存在的根本价值,提高学术质量水平乃是学术期刊办刊人永恒的第一要务。     

The development of pattern recognition ability in children

Pattern recognition development was studied in high and low ability preschool, kindergarten, and first-grade youngsters. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of a youngster to find: (a) duplicate patterns and elements to a model; (b) the opposite pattern to a model; and (c) duplicate patterns but different elements than in the model. Aside from main effects for grade level, ability level, and pattern task, a significant three-way interaction was noted. This interaction was analyzed in terms of its component simple effects. The implication of these simple interaction effects for Piagetian theory and educational practice were discussed.     

Ethnic and regional influences on teachers' evaluations of oral answers

Tape recordings were made of six white and six black ninth-grade northern boys speaking identically worded answers to typical school questions. Black students were given significantly higher grades than white students by 56 white and 50 black southern teachers. Black teachers gave significantly higher grades than white teachers, but no significant interaction was found between students' and teachers' ethnic group. The study is a partial replication of a previous study in which it was found that black students were given significantly lower grades than white students by northern white teachers.     

Attributions in a mastery instructional system: Is an emphasis on effort harmful?

Self-worth theorists have claimed that students of lower ability may reduce effort in likely failure situations to avoid the attribution of poor performance to their own incompetence. The likely success of mastery learning, an instructional technique stressing student persistence, has been questioned because of this phenomenon. Several studies which examined the hypothesized relationship between achievement, effort, and perceived ability within a mastery context were conducted. In none of the studies did it appear that students reduced effort because of the threat of failure or that expending effort led to lower estimates of ability. In fact, students expending effort rated their ability as having a more positive influence on performance than less persistent students. It is argued that mastery learning, like some achievement change programs, encourages students to attribute their performance to their level of effort.

Developmental factors influencing exceptional status at age six years

A multivariate analysis of exceptional states in 384 children aged 6 years is presented. Predictors were six items of information in the domain of child development, four items were in the domain of social factors, and three items were maternal traits. Criteria were six of nine exceptional states on which there were enough cases for multivariate analysis. The AID-4 interaction regression method was the technique of analysis applied to data gathered by prospective longitudinal study. No consistent sets of predictors were found for the criteria. However, Coddington's Life Changes scores were frequently observed as prime sources of variance. Social class scores were also important influences on criteria of exceptionality.
