In order to gain clarity about historical facts the historian requires as wide and as varied a range of informative documents as possible. These documentary sources include all texts, objects or facts, from which knowledge of the past can be gained; texts such as annals, chronicles, letters, reports, certificates; things like relics, buildings, ruins, primers, stone axes; and facts or conditions still in existence based on historical premises.  相似文献

Statistical analyses of data from an academically diverse sample of 276 adult basic and secondary education learners extends understanding of the relation of and interactions between oral reading fluency and reading competence indices. Significant interactions between total word rate and word error rate that differed in relation to two measures of reading competence suggest that adult literacy instructors should emphasize fluency instruction to a greater or lesser degree depending on whether the major goal of instruction is academic reading (e.g., being able to comprehend a textbook) or functional reading (e.g., being able to fill out a job application).  相似文献

Abstract

The Learning Council, a corporate interdivisional enterprise, employs distance learning to meet the learning needs of the organization. Specifically, distance learning is used to increase participation in the Johnson &; Johnson tuition reimbursement program, to offer learning opportunities to employees from a variety of sources, and to bring formal university courses on‐site for employees. The Learning Council is continuing to evaluate these programs as the business environment changes. This article reviews these applications of distance learning and lists considerations for other organizations interested in distance education opportunities. The use of distance learning methods facilitates the maintenance of flexibility and responsiveness in providing continuous learning for employees. The use of a combination of various distance learning methods works well, giving the company a “business edge.”  相似文献

We describe a systematic study of skills for solving problems in basic physics, a domain of practical significance for instruction, but not of prohibitive complexity. Our studies show that an inexperienced student tends to solve a problem by assembling individual equations. By contrast, an expert solves a problem by a process of successive refinements, first describing the main problem features by seemingly vague words or pictures, and only later considering the problem in greater detail in more mathematical language. We have formulated explicit theoretical models with such features and have supported them by some detailed observations of individuals. In addition, experimental instruction incorporating such features seems to improve problem‐solving performance significantly. These investigations yield thus some basic insights into thinking processes effective for problem‐solving. Furthermore, they offer the prospect that these insights can be used to teach students improved problem‐solving skills and to modify common teaching practices which inhibit the development of such skills.  相似文献
