In recent decades, parental involvement in their children’s education has been steadily increasing. Perhaps the ultimate form of parental involvement is the phenomenon called elective home education – EHE (also known as homeschooling). It is customary to divide EHE into two categories according to the degree of structure: structured EHE and unstructured EHE (or unschooling). Advocates of structured learning study in the home framework according to a defined curriculum, whereas unstructured learning advocates study content determined in accordance with the child’s wishes, with no external dictates. This division relates to learning as one entity. This article proposes to distinguish between two dimensions of structure: content and process. In order to demonstrate this distinction, qualitative research was conducted in which 30 mothers who educate their children at home were interviewed and asked what they actually do within the framework of EHE. The research findings suggest that the two types of EHE are indeed different from one another with regard to the structure of the content of instruction and learning as well as the structure of the process. The article addresses the importance of broadening the traditional distinction (structured and unstructured EHE) to include content and process. 相似文献

In this paper, fault detection and isolation (FDI) in linear uncertain dynamic systems is addressed. The main contributions consist of the formulation of the FDI problem as a filter-based multi-objective optimization problem and the study of the tools used for the solution. The design objectives are formulated in terms of H∞, H- and generalized H2 performance specifications as well as regional constraints on filter poles. The problem is solved using linear matrix inequality (LMI) and generalized structured singular value (μg) techniques. Special design features are illustrated through a simulation example and experimental results from a controlled hydraulic process are provided to demonstrate the potential of the proposed procedure. 相似文献

Summary The current shift to mediated and WWW-based teaching and learning requires both teachers and learners to adapt established classroom practice to the new online environment. Many of the electronic systems currently on offer fail to support the complexity of interaction necessary to facilitate deep learning. This paper identifies the instructional strategies or “micro-genres” that form the essence of successful classroom teaching, and describes an online system, WebTeach(tm), that attempts to provide structured teacher-learner interactions that build on the familiar activities and strategies of the classroom. Through access to these “micro-genres” in an online classroom, both teacher and learner can reduce the cognitive demands of learning new processes while focusing on strategies for deep learning related to the content of the course. 相似文献
