This research draws upon merged national databases containing federal crime statistics, community demographic data, and campus characteristics. The study displays the trends in campus crime since 1974, and using 1990 data, examines the relationships between three measures of campus crime and 23 predictors developed for this study. The results show that campus rates of both violent crime and property crime are falling, especially since 1985. Moreover, students are considerably safer on campus than in the cities and communities surrounding them. The lowest average crime rates are found at two-year colleges, while the highest overall rates are at medical schools and health science centers. None of the community characteristics, including community crime and poverty rates, are significantly associated with campus crime. While campus organizational measures in general are more highly related to campus crime than are student characteristics, we find differences in the patterns of variables associated with violent crime versus property crime. Factors associated with property crime are partially consistent with existing theory on criminal activity. Factors associated with violent crime are more complex and difficult to predict.An earlier version of this paper was the winner of the regional Best Paper Award from the North East AIR annual meeting in Bolton Landing, N.Y., November 1993. It was presented again at the Association for Institutional Research Forum, New Orleans, Louisiana, May 1994.  相似文献

Researchers in the field of gifted education are becoming increasingly aware that a variety of research approaches can make contributions to research on giftedness. This paper describes task analysis, a research methodology derived from counseling process research. Task analysis appears to be a useful research approach for building theoretical models of how therapeutic and educational interventions can facilitate positive changes in gifted children. The paper traces the historical development of task analysis methodology, describes the steps involved in conducting a rational‐empirical task analysis of change processes, and provides an example of how task analysis methodology might be applied to investigations of change processes in the field of gifted education.  相似文献

The present study examined characteristics of students who took advantage of the opportunity to learn Algebra II from a highly skilled teacher. In particular, student information was gathered concerning: (a) the amount of mathematics students knew prior to the class, (b) their motivation for learning mathematics, (c) the number and types of interactions they had with the teacher during class, (d) degree of self-regulation, and (e) general aptitude. A model for achievement was used that suggests both opportunity and propensity are important (i.e., students must be willing and able to take advantage of opportunity). Support for the model was found. Propensity to take advantage of a highly favorable opportunity accounted for almost sixty percent of the variance in achievement. In particular, students who were self-regulated, had strong mathematics backgrounds, and had low levels of frustration benefited more from high-quality instruction.  相似文献

The first part of this paper describes the rationale for and process of engaging student teachers in action research during the fourth and final year of their teacher education, which is also their first year as teachers (induction year). During this year the novice teachers are engaged in an action research project as a compulsory assignment in the course ‘Teacher as researcher’. The objective of the course is to provide novice teachers with reflective tools for systematic examination of their work as teachers. The second part of the paper documents the learning process of the teachers of the course (which can also be viewed as action research), since we jointly planned the course, engaged in reflective dialogues with the students and among ourselves and systematically examined our work by personal diary writing and inviting informal and more formal (questionnaire) feedback from the students. The process of our action research is documented in this paper, whereas the product is hopefully implemented in teaching a better course and in more effective support of our students.

La première partie de cet article explique la logique d'une recherche basée sur l'action menée pendant la quatrième et dernière année de formation éducative, qui par ailleurs est aussi la première année de pratique comme enseignant (année d'essai). Pendant l'année, les novices doivent s'adonner à un projet de recherche pour le cours ‘Enseignant comme chercheur’ dont le but est de leur procurer des outils de réflexion pour pouvoir examiner systématiquement leur travail comme enseignant. La seconde partie de l'article illustre ce que nous, les professeurs du cours, apprenons, ce qui peut être considéré comme recherche basée sur l'action puisque nous avons pensé le cours conjointement, et avons établi des dialogues de réflexion avec les étudiants et entre nous, avons systématiquement examiné notre travail en tenant un journal, avons requis des commentaries critiques formels (sous forme d'un questionnaire) et informels des étudiants. Le processus de notre recherche basée sur l'action est illustré dans cet article et nous espérons que son fruit se fera sentir dans un cours meilleur et un soutien plus efficace des étudiants.

La primera parte de este trabajo describe el racional y el proceso de involucramiento de estudiantes de marcos de formación docente en la investigación en acción, durante el cuarto y último año de su formación, el cual a su vez constituye el primer año como docentes (año de prueba). Durante este año los jóvenes docentes se involucrarán en el proyecto de investigación en acción como una tarea obligatoria en el marco del curso ‘El docente como investigador’. El objetivo del curso es de proveer a los jóvenes docentes de herramientas reflexivas para lograr un análisis sistemático de su labor como docentes. La segunda parte del trabajo documenta el proceso de enseñanza de los docentes del curso, nosotros, que a su vez puede ser visto como una investigación en acción ya que hemos planificado el curso en conjunto, nos sumergimos en diálogos reflexivos con los estudiantes y entre nosotros, y hemos analizado sistemáticamente nuestra tarea a través de la escritura de un diario personal, además de solicitar en forma informal y más formal (cuestionario) una retroalimentación de parte de los estudiantes. El proceso de investigación en acción se documenta en este trabajo, esperamos que el producto del mismo sea implementado en el mejoramiento del curso y un apoyo más eficaz para nuestros estudiantes.

Der erste Teil dieses Artikels beschreibt die Leitgedanken und Vorgehensweise eines Aktionsforschungsprojekts mit Lehramtsstudenten im vierten (somit letzten) Jahr ihrer Ausbildung, das zugleich ihr erstes Jahr als Lehrer ist (‘Bewährungsjahr’). Im Laufe dieses Jahrs sind die Neulehrer verpflichtet, an einem Aktionsforschungsprojekt im Rahmen einer Pflichtlehrveranstaltung, ‘Lehrende als Forschende’ teilzunehmen. Ziel dieser Lehrveranstaltung ist es, Neulehrer mit reflektiven Instrumenten für die systematische Untersuchung ihrer eigenen Arbeit als Lehrer auszurüsten. Im zweiten Teil dieses Artikels wird der Lernprozess der Lehrpersonen dokumentiert, die diese Pflichtlehrveranstaltung gemeinsam entwickelten und abhalten. In kritsch‐reflektivem Dialog mit den Studierenden und miteinander, durch Führen eines perseonlichen Tagebuchs und Auseinandersetzung mit formalen und informalen Reaktionen der Studierenden auf die Lehrveranstaltung, fand somit ein Aktionsforschungsprojekt der Lehrerausbilder selbst statt. Der Lernprozess, der sich in diesem Artikel niederschlägt, wird in einer verbesserten Lehrveranstaltung und einer effektiveren Unterstützung der Studierenden beim Übergang in die Berufswirklichkeit umgesetzt.  相似文献

ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.  相似文献
