This paper studies conceptions of woodwind students regarding learning and teaching music, within the framework of implicit theories. It analyzes whether there are differences related to participants’ instruction level, and whether it is possible to identify profiles according to their conceptions. Sixty-eight students from three different levels at 14 Spanish conservatories took part voluntarily in this study. A multiple-choice questionnaire was used, which comprised 16 dilemmas on different situations typical of learning and teaching music. Three answers were presented for each dilemma, corresponding to the three implicit theories identified in recent years: direct, interpretative, and constructive. For each dilemma, participants were requested to choose the option they most agreed with and the one they least agreed with. Data were analyzed using chi-square tests of independence, multiple correspondence analysis, and ascending hierarchical classification. From the results obtained we can state that as students’ age and level of instruction increase, so does the level of sophistication of their conceptions. Three conceptual profiles were identified: direct, direct-interpretative, and constructive, which are consistent with prior results on conceptions of teaching and learning in other domains. Implications for education are discussed.  相似文献

ABSTRACT

As Internet usage has proliferated in recent years so have online security threats. Internet users are increasingly susceptible to online security threats. Using a qualitative approach, this study conducted 18 focus groups to examine how three different generations perceive online safety, use coping strategies, and protect themselves online: Silent and GI generation (SGI) (born 1945 or earlier), older Baby Boomers (1946–1954), and Millennials (1977–1992). Results show that although each generation shares a variety of online safety concerns, SGIs and Boomers are more suspicious about online security, have less confidence in their abilities, are uncertain about the effectiveness of protection resources, perform fewer protection behaviors, and are more likely to rely on others’ assistance compared to the Millennial group. Our findings indicate online safety training is needed for all three generations, but especially for older adults. Tailored approaches are suggested to reach different generations.  相似文献

Transformative environmental education: a collective rehearsal for reality   总被引:1,自引:1,他引:0  
This paper puts forward an alternative view on sustainable development, arguing that the separation between the economy, the environment and the social in the Brundtland model obscures the societal character of the economy, the economic bases of the social, and the fact that the environment is a societal product. We differentiate between strong and weak sustainability, arguing that the threat of environmental degradation can only be addressed at the level of the relations of production, consumption and political relations. Building on this perspective, we advocate a form of transformative environmental education which engages learners and teachers in a process of self‐reflective transformation. We illustrate this through two examples: action competence and Boal’s Theatre of the Oppressed.  相似文献

Newcombe NS 《Child development》2003,74(4):1050-1052
Investigators of complex phenomena often seek to isolate variables of interest by statistical control. However, they run the risk of studying situations that do not exist in the real world, missing mediational links, and drawing incorrect policy conclusions. In the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network article in this issue, amount of time in child care was studied controlling for family income and maternal depression. However, use of child care is closely linked with maternal employment, which increases family income and decreases maternal depression, which in turn are linked to children's socioemotional adjustment. Hence, the negative effects of amount of time in child care reported in the article are likely overestimated relative to causal pathways in the lives of real families.  相似文献

Research Findings: The purpose of this study was to examine within-group individual differences in the code-related and oral language abilities of an economically stressed Spanish-speaking English language learner (ELL) preschool sample and to evaluate the predictive relationship of these differences to later listening comprehension. Latent class analysis was used to identify similarities in both the latent and outcome variables to form classes of students with similar profiles on the measured variables. Our 1st finding confirmed the existence of 4 distinct psychometrically validated profiles: (a) Low English Language, Average Spanish Language, Mixed Spanish Code-Related (prevalence 19.4%); (b) Average English Language, Strengths in Spanish Language and Spanish Code-Related (24.2%); (c) Mixed English and Spanish Language, Low Spanish Code-Related (prevalence 34%); and (d) High English Language, Average Spanish Language, Mixed Spanish Code-Related (prevalence 22%). The resulting profiles demonstrated that English and Spanish code- and language-related domains of emergent literacy developed unevenly across the Spanish-speaking ELL preschoolers. Relative strengths and weaknesses in code- and language-related skills were also found to be meaningfully related to end-of-year listening comprehension—a precursor to reading comprehension. Finally, profiles yielded meaningful variability along sociodemographic variables. Practice or Policy: Implications, limitations, and directions for future research are discussed.  相似文献

Based on case studies of a private and a public Mexican university, this research studied the economic strategies adopted by institutions of higher education to respond to financial stress. Rather than assuming that these strategies were selected primarily on the basis of their economic efficiency, the social processes that led to their adoption were explored.Economic development theory was employed to describe and conceptualize the universities' responses to financial difficulties. The concepts of institutional rules and rational myths in the environment and the processes that lead organizations to become similar to their environment were utilized to explore the role of the institutional environment on decision-making in times of fiscal uncertainty.Results indicate that financial stress was managed through economic measures, however the universities' institutional environment filtered and gave specific meaning to particular decision strategies. Institutional rules in the environment, acquiring the character of rationalized myths, pemeated and determined decision-making choices, and were evidenced in and sustained by mimetic, normative and coercive processes. In this light, the institutional environment pervaded and predicted rational decisions.  相似文献

This study tested a modified version of Tinto's student attrition model on a Chicano student population in two-year colleges. Structural equation modeling and LISREL VI were used to examine the parameter estimates of the structural and measurement models of the hypothesized causal model. Measures of goodness of fit were examined to provide indices for the overall fit of the causal model in the study. The measurement and structural models were found to represent a plausible causal model of student retention among Chicano students. Although the measures used in assessing the fit of the model reflected the overall strength of the hypothesized model, the present study was not entirely supportive of Tinto's model. The findings were only minimally supportive of the hypothesized relationship between measures of academic integration and retention. The results indicated that the hypothesized relationship between measures of social integration could not be substantiated. Moreover, measures of initial commitments were found to have a significantly large direct effect on the dependent variable, retention.  相似文献

The standardized, indicated school‐based prevention program “Networks Against School Shootings” combines a threat assessment approach with a general model of prevention of emergency situations in schools through early intervention in student psychosocial crises and training teachers to recognize warning signs of targeted school violence. An evaluation study in 98 German schools with 3,473 school staff participants (Mage = 46.2 years) used a quasi‐experimental comparison group design with three measurement points (pre, post, and 7 months followup) with schools randomly allocated to implementation conditions. The study found increases in teachers' expertise and evaluation skills, enhanced abilities to identify students experiencing a psychosocial crisis, and positive secondary effects (e.g., teacher–student interaction, feelings of safety).  相似文献

The moment is tense ... and somewhat confusing. I am in my office with a small group of five-year-olds reading a story when Mrs. Wilson arrives. She is young, pretty, and looking very serious. “Billy says that his father visited here today!”  相似文献
