Community colleges have a high percentage of women students and a higher percentage of women faculty and administrators than do four-year colleges. Yet the extent to which the community college offers an equitable work and study site for women is not clear. The authors seek to determine this by applying to existing literature an adaptation of Hurtado, Milem, Clayton-Pederson, and Allen's framework for examining an institution's climate for diversity. After applying this framework, the authors conclude that women have been an important part of the community college student and employee base since its inception as the junior college, that numerically women are well represented, and that the climate, while not perfect, is relatively good for women. However, they argue that this situation may be due more to accident than to intentional action or behavior on the part of institutional leaders. 相似文献

Higher education institutions should provide adequate training for teachers in order to increase their awareness of the complex interplay between technology, pedagogy and the cognitive knowledge in their disciplines. However, research has shown that providing effective staff development from teacher educators to support these teachers’ skills is not straightforward. An online teacher training programme created and implemented by a team of 14 teacher educators in a cross-institutional programme in the Netherlands was followed by 67 teachers. Data were gathered using a TPACK (Technological, Pedagogical, Content Knowledge) instrument in a pre-post test design. Furthermore, (perceived) learning satisfaction was measured in order to determine whether the design was appropriate. The results indicate that the teachers’ TPACK skills increased substantially. Furthermore, most participants were positive about the design and implementation of the online professionalisation programme. Nonetheless, not all teachers were able to effectively learn in this context, requiring further fine-tuning and research. 相似文献

The purpose of this study was to investigate the distinct forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior during early childhood ( n = 101; M age = 45.09 months). Forms, but not functions, of aggressive behavior were stable over time. A number of contributors to aggression were associated with distinct subtypes of aggressive behavior. Females and socially dominant children were more relationally aggressive and older children were less physically aggressive than their peers. Longitudinal analyses indicated that social dominance predicted decreases in physical aggression and peer exclusion predicted increases in relational aggression. Overall, the results provide support for the distinction between subtypes of aggression in early childhood. 相似文献

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared. 相似文献

Many non-linear programming algorithms employ a univariate subprocedure to determine the step length at each multivariate iteration. In recent years much work has been directed toward the development of algorithms which will exhibit favorable convergence properties on well-behaved functions without requiring that the univariate algorithm perform a sequence of one-dimensional minimizations.In this paper a direct search method (the golden section search) is modified to search for acceptable rather than minimizing step lengths and then used as the univariate subprocedure for a generalized conjugate gradient algorithm. The resulting multivariate minimization method is tested on standard unconstrained test functions and a constrained industrial problem. The new method is found to be relatively insensitive to tuning parameters (insofar as success or failure is concerned).A comparison of the golden section acceptable-point search (GSAP) with other popular acceptable-point methods indicates that GSAP is a superior strategy for use with the conjugate directions-type algorithms and is also suitable for use with the quasi-Newton methods. The comparison are based on equivalent function evaluations required to minimize multivariate test functions. 相似文献
