Seventh-grade Students (seventh-grade + student)
Selected AbstractsThe development of seventh graders' views of nature of scienceJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 4 2008Rola Khishfe Abstract This study investigated the development in students' nature of science (NOS) views in the context of an explicit inquiry-oriented instructional approach. Participants were 18 seventh-grade students who were taught by a teacher with "appropriate" knowledge about NOS. The intervention spanned about 3 months. During this time, students were engaged in three inquiry-oriented activities that were followed by reflective discussions of NOS. The study emphasized the tentative, empirical, inferential, and creative aspects of NOS. An open-ended questionnaire, in conjunction with semi-structured interviews, was used to assess students' views before, during, and after the intervention. Before instruction, the majority of students held naïve views of the four NOS aspects. During instruction, the students acquired more informed and "intermediary" views of the NOS aspects. By the end of the intervention, the students' views of the NOS aspects had developed further still into informed and "intermediary." These findings suggest a developmental model in which students' views develop along a continuum during which they pass through intermediary views to reach more informed views. Implications for teaching and learning of NOS are discussed. © 2007 Wiley Periodicals, Inc.

Moje Recent curriculum design projects have attempted to engage students in authentic science learning experiences in which students engage in inquiry-based research projects about questions of interest to them. Such a pedagogical and curricular approach seems an ideal space in which to construct what Lee and Fradd referred to as instructional congruence. It is, however, also a space in which the everyday language and literacy practices of young people intersect with the learning of scientific and classroom practices, thus suggesting that project-based pedagogy has the potential for conflict or confusion. In this article, we explore the discursive demands of project-based pedagogy for seventh-grade students from non-mainstream backgrounds as they enact established project curricula. We document competing Discourses in one project-based classroom and illustrate how those Discourses conflict with one another through the various texts and forms of representation used in the classroom and curriculum. Possibilities are offered for reconstructing this classroom practice to build congruent third spaces in which the different Discourses and knowledges of the discipline, classroom, and students' lives are brought together to enhance science learning and scientific literacy. © 2001 John Wiley & Sons, Inc.

We contrast the explanatory power of ethnic labels (African American, non-Hispanic White, Mexican American, and mixed ethnicity) and two dimensions of ethnic identity in predicting drug use. One dimension focuses on perceived ethnically consistent behavior, speech, and looks, while the other gauges a sense of ethnic pride. Ethnic labels were found to be somewhat useful in identifying differences in drug use, but the two ethnic identity measures, by themselves, did not generally help to explain differences in drug use. In conjunction, however, ethnic labels and ethnic identity measures explained far more of the differences in drug use than either did alone. The findings indicate that the two dimensions of ethnic identity predict drug outcomes in opposite ways, and these relations are different for minority students and non-Hispanic White students. Generally, African American, Mexican American, and mixed-ethnicity students with a strong sense of ethnic pride reported less drug use and exposure, while ethnically proud White students reported more. Ethnic minority students who viewed their behavior, speech, and looks as consistent with their ethnic group reported more drug use and exposure, while their White counterparts reported less. These findings are discussed, and recommendations for future research are provided. [source] Effectiveness of a School-Based Intervention at Changing Preadolescents' Tobacco Use and AttitudesJOURNAL OF SCHOOL HEALTH, Issue 6 2002Esther M. VanDyke MD ABSTRACT: This study evaluated the effectiveness of a tobacco intervention on preadolescents' tobacco use and attitudes. A tobacco assessment questionnaire was distributed to seventh-grade students in May 1997 (N = 229) and 1999 (N = 230). During the 1998,1999 academic year, sixth-grade students at the intervention school received a tobacco intervention. Though not statistically significant the number of smokers at the intervention school decreased from 43.2% to 31.1% after the intervention (p = .09). These students predicted less smoking in five years (29.6% to 19.8%, p = .078) and 20 years (28.4% to 13.2%, p = .004). Because of the difficulty in reducing smoking rates at the population level, the nonsignificant results can be viewed as a success rather than a setback. When faced with increasing use trends, an intervention can at least hope to achieve a decrease or slow the rate of growth, and the program succeeded in that respect. School-based interventions can effectively influence preadolescent' attitudes concerning tobacco use. Future programs should begin earlier and be reinforced yearly. [source] Relational Aggression and Adverse Psychosocial and Physical Health Symptoms Among Urban AdolescentsPUBLIC HEALTH NURSING, Issue 6 2009Jessica Roberts Williams ABSTRACT Objectives: The purpose of this study was to examine relational aggression and its relationship with adverse psychosocial and physical health symptoms among urban, African American youth. Design and Sample: Quantitative, cross-sectional survey design. The sample consisted of 185 predominantly African American (95.1%) seventh-grade students (mean age: 13.0; female: 58%) attending 4 urban middle schools. Measures: The Children's Social Behavior Scale and Social Experience Questionnaire were used to measure relational aggression and relational victimization. The Pediatric Symptom Checklist was used to assess psychosocial difficulties, including internalizing behaviors, externalizing behaviors, and attention problems. Physical health symptoms were measured with questions about colds/flu, headaches, and stomach aches. Results: 2-way multivariate analysis of variance revealed significant differences in externalizing behavior, with perpetrators reporting higher levels than nonperpetrators. Victims reported more internalizing behavior than nonvictims; however, this was only significant for males. For females, significant negative effects on health outcomes were found, resulting from the interaction of perpetration and victimization. Conclusions: Findings suggest that relational aggression is a common occurrence among urban, minority adolescents and may result in adverse health outcomes. These results provide several avenues for future research and implications for healthcare practice. Intervention strategies are needed to prevent relational aggression and continual or subsequent adverse health symptoms. [source] | ||||||||||
