This study used an ecological framework to examine predictors of delinquent behaviors among 91 sixth-grade Latino youth. Both proximal and distal contextual factors were assessed to determine their impact on various forms of delinquency, such as violent behaviors, violent thoughts, substance abuse, and general delinquency (e.g., skipping school). Attitudes toward school, mobility (number of moves to new schools and neighborhoods), and exposure to community violence were distal variables, whereas attachment to parents and attachment to peers were considered more proximal variables. Environmental experiences or exposure to distressing community violence was the strongest predictor of delinquent outcomes. The results were discussed in terms of school officials' developing linkages with the community to promote safe environments for youth. 相似文献

In Grutter vs. Bollinger, the U.S. Supreme Court ruled that the use of race as one factor, among many in admissions decisions is constitutional. It is not known, however, whether future legal opinions will continue to uphold the use of affirmative action policies. Some have argued that class-based preferences can achieve many of the same goals as in affirmative action while being more likely to withstand legal challenges. To date, no empirical studies have been conducted on the potential impact of a class-based admissions policy if implemented at an undergraduate institution. This paper reports on a study at a selective public college and compares a number of outcomes under three admissions models: the original admissions decisions, a purely academic model, and an socio-economic status (SES)-based model. The findings showed that use of the SES-based model would have led to a more academically qualified class than in the original admitted class while maintaining substantially greater student diversity that was found under the academic model. An admissions policy based on preferences for socio-economically disadvantaged applicants appears to hold promise for other colleges and universities with similar institutional and applicant characteristics. The ideas and research design reported in this paper are based on the doctoral dissertation study of the second author, Undergraduate Admissions Models Incorporating Socioeconomic Factors (Johnson, 2000). 相似文献

Interviewing, as an information‐gathering tool for prospective teachers of the deaf, was used to document the perspectives which deaf children, their parents, teachers and administrators bring to the mainstreaming process. Data revealed the different, and sometimes competing priorities of mainstreaming participants; these priorities are discussed in terms of their impact upon the success or failure of the mainstreaming process and the preparation responsibilities of teacher training programs. 相似文献

The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested. 相似文献

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision. 相似文献

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems. 相似文献

Functional Behavior Assessments (FBAs) utilize direct and indirect methods to collect data on student behavior to generate a functional hypothesis and drive intervention development. School psychologists are trained to conduct FBAs and use them regularly in schools. However, no evidence exists describing the specific practices used by school psychologists when they conduct FBAs. In this study, 199 respondents completed a web‐based survey developed using expert review and cognitive pretesting. Most respondents reported their gender as female (87%), were between 30 and 39 years old (50%), and practiced at the Specialist level (57%). Respondents reported receiving training in FBA across multiple sources and utilizing multi‐method data collection methods when conducting FBAs. A large amount of variability was observed in the specific instruments used by school psychologists, with a substantial proportion using forms that were not standardized or pre‐constructed. Implications for current practitioners, trainers, and researchers are described. 相似文献
