There remains significant confusion surrounding the purpose, audience, and proposed application of the Framework for Information Literacy for Higher Education. This exploratory study addresses the question of whether undergraduate students can understand the language and concepts in this document. By presenting student responses to pretest questions recorded at the beginning of a semester-long research methods course, this article shows that students can, even on first impression, begin to make sense of the complexity and richness found in the Framework for Information Literacy for Higher Education.  相似文献

With the recent adoption of the Common Core standards in many states, there is a need for quality information about textbook alignment to standards. While there are many existing content analysis procedures, these generally have little, if any, validity or reliability evidence. One exception is the Surveys of Enacted Curriculum (SEC), which has been widely used to analyze the alignment among standards, assessments, and teachers’ instruction. However, the SEC can be time‐consuming and expensive when used for this purpose. This study extends the SEC to the analysis of entire mathematics textbooks and investigates whether the results of SEC alignment analyses are affected if the content analysis procedure is simplified. The results indicate that analyzing only every fifth item produces nearly identical alignment results with no effect on the reliability of content analyses.  相似文献

At the turn of the 21st century a methodological analysis of the planetary development of civilization became a topical issue in world science. Such an analysis is based on a framework of categorical concepts adopted for active use in globalistics, namely, the biosphere, sociosphere, technosphere, noosphere, and infosphere. The given context provides a new perspective on the phenomenon of information and informatics, with the latter having experienced increasing demands as a popular scientific discipline in the field of information. In the contemporary setting, these phenomena can be adequately evaluated only in connection with the above concepts.  相似文献

The purpose of this investigation is to examine some solutions to the problems involved in the learning and teaching of biological inheritance and the evolution of living beings at the secondary school level. For this, we implemented a teaching programme which takes into account a constructivist approach to learning and analysed the progress in students' knowledge at different times (pre-test, post-test and retention test). Qualitative and quantitative analysis of the results show that the programme instilled a knowledge close to what might be considered adequate for this educational level. As a follow up, we propose certain disciplinary criteria for selecting and sequencing the content to be taught and discuss the educational circumstances which favour the construction of student knowledge on these topics.  相似文献

Abstract

Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable.  相似文献

The quest for culture‐free or even culture‐fair tests of abilities has not succeeded. In their place, a culture‐specific approach to testing is suggested to identify talent hidden by socioeconomic deprivation. The culture‐specific approach to testing for artistic talent in black students suggested here is “Tactuality.” Tactuality was constructed by finding characteristics common to black cultural strengths and the artistically talented. The four characteristics of Tactuality identified were: emotional intensity, flexibility and open‐endedness, holistic perception, and tactile sensitivity. A Tactuality Test (Tac Test) was devised based on these four characteristics. The Tac Test was pilot tested with 63 fourth‐graders comprising an ethnic mixture. Statistical problems with validation occurred, requiring further statistical analysis and a larger test population.  相似文献
