Onset,development, and prevention of drinking and driving among adolescents

An etiological study was designed to investigate the onset and development of drinking and driving among adolescents who recently received their driver’s license. A theoretical framework, derived from Problem Behavior Theory, was applied in order to identify environmental, personality and behavioral factors associated with drinking and driving. Among students who reported that they had driven a motor vehicle in the past three months (N=1416), 33 percent of the males and 22 percent of the females (who averaged 16.7 years) reported “drinking at least two drinks on a single occasion prior to driving” at least once in the previous three months. Personality factors (including perceived ability to drive after drinking, tolerance of drinking and driving, and lack of self-confidence in avoiding drinking and driving situations), perceived environmental factors (perceived car availability and friends modelling of drinking and driving) and behavioral factors (riding with a drinking driver and marijuana use) accounted for a large proportion (49%) of the variance in reported drinking and driving. It is recommended that school-based, peer-led educational programs be designed which target young adolescents prior to the age at which legal driver license is obtained. The programs should be broad-based and consider drinking and driving within the larger context of drinking and driving related behaviors and traffic safety in general.     

Do parents make a difference to children’s academic achievement? Differences between parents of higher and lower achieving students

Differences in family factors in determining academic achievement were investigated by testing 432 parents in nine independent, coeducational Melbourne schools. Schools were ranked and categorized into three groups (high, medium and low), based on student achievement (ENTER) scores in their final year of secondary school and school improvement indexes. Parents completed a questionnaire investigating their attitudes towards the school environment, their aspirations, expectations, encouragement and interest in their child’s education (adapted from scales constructed by Marjoribanks). They also responded to six open‐ended questions on their attitudes to achievement and to their (child’s) school. Multiple regression analyses revealed that parental expectations of their children’s educational level made the strongest unique prediction of high achievement followed by the length of time they had maintained their expectations. Limitations discussed include the disparity in meaning associated with the definition of school success and whether these results can be generalized to all students considering the biased sample (socio‐economic status).     

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.     

Failure to block control by a relevant stimulus

Pigeons were trained to depress a treadle in the presence of a discriminative stimulus, either a tone or illumination of red houselights, in order to obtain access to grain or avoid electric shock. In avoidance training, the auditory discriminative stimulus yielded faster acquisition than did the visual one. In appetitive training, the visual discriminative stimulus yielded faster acquisition than the auditory one. Experiments 2 and 3 used these stimuli in Kamin’s (1969) blocking design. In Experiment 2, when the pigeons were trained to depress a treadle in the presence of tone to obtain grain and then red light was added as the redundant stimulus, the light acquired stimulus control over treadlepressing; blocking was not observed. In Experiment 3, when the pigeons were trained to depress a treadle in the presence of red light to avoid electric shock and then tone was added as the redundant stimulus, the tone acquired stimulus control over treadle-pressing. Again, blocking was not observed. The implications of these results for several models of stimulus control are discussed.     

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。     

A Developmental Perspective on Peer Rejection: Mechanisms of Stability and Change

This study examines factors associated with the relative stability of peer rejection among elementary school-aged children. Forty-four initially rejected children (some of whom improved their social status while others remained rejected over a 2-year period) were recruited from a larger sociometric sample. Prospective analyses were conducted to determine whether peer nominated aggression and children's perceptions of their own status in fourth grade were predictive of status improvement by the end of fifth grade. In addition to prospective analyses, initially rejected children and their mothers were invited to participate in a retrospective interview about their social experiences over the past 2 school years. Results of prospective and retrospective analyses suggested that perceived social status, participation in extracurricular activities, locus of control, and parental monitoring were all positively related to status improvement among initially rejected children. Surprisingly, aggressive behavior also was positively related to status improvement among initially rejected boys.     

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.
