A mathematical theory is developed for an imagined device termed a “junctor”. A junctor could be used to interconnect two n-terminal networks giving rise to another n-terminal network. Actually a junctor is itself a simple network with three banks of n-terminals internally connected in some fashion by perfectly conducting wires. Adjacency matrices are formulated to analyze various junctors and their current flows. The main problem treated concerns conditions which would ensure that the junctor operation is associative. 相似文献

Preschoolers' scores on the Developmental Test of Visual Motor Integration (VMI), the Slosson Intelligence Test (SIT), and the ABC Inventory (ABCI) were analyzed for race and sex differences. Separate ANOVAs revealed no race effect on the VMI, whereas race differences favoring whites were found for the SIT and ABCI. There were no effects for sex on any measure, nor were there any interactions. Results are discussed in terms of the inconsistent findings for race effects in the perceptual-motor literature. 相似文献

With a view to attracting more students and offering flexible learning opportunities, online teaching and learning is becoming increasingly widespread across the higher education sector. It is now found across a wide range of disciplines (e.g., business, health, psychology, accounting, information technology) and program levels (e.g., from associate degrees to doctorate degrees). Online delivery is also strongly represented in the teacher education sector at many universities. Research of online delivery in higher education generally and teacher education specifically has pointed to a range of benefits and challenges associated with this mode of learning. Within the teacher education literature, many aspects of the online preparation of teachers remain poorly understood. More specifically, there is scant literature on the experiences and beliefs of teacher educators in relation to their readiness and preparation for online teaching as well as their beliefs in relation to the appropriateness of online education for preservice teachers. This article responds to this gap in the literature and reports on an exploratory study that worked with academic staff, teaching in a fully online teacher education course, at a mid-size Australian university. Twenty-seven teacher educators completed a 34-item questionnaire that consisted of closed and open-ended questions. With regards to readiness and preparation for teaching online, the majority of teacher educators reported lacking confidence and competence in the technological and pedagogical skills required to teach online. By and large, the study participants were welcoming of individualized “at-elbow” support that seemed to abate some of their fears of online teaching. The teacher educators were generally divided on whether the online classroom was an appropriate method for preparing preservice teachers. This article concludes with several recommendations for consideration by teacher educators who work in an online environment and sets the stage for a more ambitious study. 相似文献

This article considers the involvement of schools and teachers in schemes which develop work with young offenders as an alternative to prosecution. Data from one such experimental scheme are presented and discussed. Issues are raised about the consequences of schools’ involvement in this kind of policy initiative which begins outside the educational system and entails co‐operation with professional workers in other statutory agencies. A central theme is whether a tightening of the welfare network in this way is unambiguously in the interests of young people. 相似文献
