This study examines the relationship between Tongan students’ attitudes and beliefs towards their school experiences and their academic achievement on the high-stakes National Certificate of Educational Achievement (NCEA) assessments in English and mathematics. Data were obtained from using previously published self-reported inventories on a sample of Tongan senior students in New Zealand secondary schools. Confirmatory factor analysis of students’ conceptions found good fit measurement models for each domain (teaching, learning, and assessment). Structural equation modelling was used to identify the effect of the various beliefs upon students’ total score in each subject and upon internal and externally assessed performance. It was noted that different beliefs became statistically significant predictors of performance, depending on the subject and type of assessment. Nonetheless, all three constructs played some role in at least one subject. A small-to-moderate proportion of variance in NCEA performance could be attributed to student beliefs, suggesting that efforts to help students adopt adaptive beliefs will have beneficial consequences for those students.  相似文献

This study investigated teachers’ experiences of closeness during interactions with the group of children in child care. Structured interviews were conducted with 24 female teachers who were teaching children between the ages of three and five (mean age = 3.9) regarding their perceptions of closeness with the group of children in the class. Qualitative analyses of the interviews revealed a group solidarity domain of teacher–group relationships composed of three dimensions which comprise emotional solidarity, consensual solidarity, and functional solidarity, with emotional solidarity most dominant in the teachers’ perceptions. This group solidarity domain was interpreted as being consistent with qualities found in Grusec and Davidov’s group participation domain. The findings that, teachers’ closeness with the group of children in the class were dominated by the emotional dimension is similar to previous research results which report the predominance of personal and intimate interactions in relational closeness between teachers and individual children. Teachers described intentional strategies for managing close group relationships that made use of interactional histories between the teachers and children in the class. These discoveries provide a new perspective on teacher closeness with groups, an area of research not often investigated. It also provides insights into the importance teachers place on connecting emotionally with children when they are with the collective group in the classroom.  相似文献

This study examines the extent to which criminal justice and criminology Ph.D. students are exposed to contemporary biological and genetic findings associated with aggression and violence. Drawing on multiple sources of information, we find little evidence showing that Ph.D. students are exposed to any biological research on crime and offending. We examine the consequences for this “trained incompetence” and offer suggestions for remedying this deficiency.

If all mankind minus one were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind. (John Stuart Mill)  相似文献

Criminology is experiencing a paradigm shift in theory and research that articulates a more interdisciplinary, biosocial mode of inquiry. Unfortunately, however, graduate‐level criminal justice education rarely encompasses biosocial training. The current review is the first in a series of works that seeks to fill this biosocial training void by providing instruction on concepts in the biological sciences and neurosciences that have direct relevance to criminal justice education and criminology. Here we introduce endophenotypes and demonstrate their relevance to the study of crime using the self‐control construct from Gottfredson and Hirschi’s general theory. Because biosocial criminology is in its nascent stage, it is critical that biosocial criminologists provide service and instruction to their social science‐trained colleagues.  相似文献

This article assesses the quality of 12 American doctoral programs by counting the number of publications of their Ph.D. graduates in a large number of criminology and criminal justice journals, and in 20 more “academic” journals. While half of the Ph.D. graduates had no publications, the 4 percent who were the most productive (the “stars”) accounted for one third of all journal articles. Publication rates up to graduation predicted publication rates after graduation. The University of Maryland, Michigan State University, the University of California at Irvine, Florida State University, and Sam Houston State University had the most productive Ph.D. graduates in academic journals. There was a significant correlation between the productivity of a program's Ph.D. graduates and the productivity of its faculty members. The academic publication rate was influenced most by prevalence (the percentage of Ph.D.s with at least one publication), rather than by the percentage of “stars” or the frequency of publications.  相似文献

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification exercises can improve insect identification performance. Also included is a discussion of how these results can be used in teaching and future research on biological identification.  相似文献
