随着知识生产模式的现代转型,大学科研活动面临日益加重的社会问责,科研评价关注的焦点逐渐从重视科研数量与质量的内部评价转向注重科研社会贡献度与影响力的外部评价。在大学卓越科研评估的基础上,2018年澳大利亚政府引入了社会互动与影响力评价。作为大学卓越科研评估的配套评价机制,社会互动与影响力评价以其更加精细化、立体化的指标体系设计,引导大学在科研活动全过程中积极与政府、产业及社会进行互动和协作,较好地兼顾了结果评价与过程评价,突出了社会贡献能力培育与机制建设,充分挖掘了科研评价的激励与导向作用。借鉴社会互动与影响力评价的评估思路,我国在清理“五唯”的过程中应明确建立质量与贡献并重的科研绩效评价体系,对大学科研的社会互动过程与实际贡献给予更多关注。  相似文献

社会生产包括三种类型:物质生产、精神生产、人类自身生产。物质生产是社会生产的物质基础:精神生产是社会生产的精神支柱;人类自身生产是社会生产的出发点和最后归宿。三大类生产之间以及它们各自内部的产业之间都要实现动态的平衡协调和谐发展。  相似文献

Soon after the discovery of the expansion of the universe, astronomers hoped to determine the parameters of the universe by comparing distant galaxies with nearby ones. Observing distant galaxies, however, meant observing them as they were long ago. A crucial assumption in these studies was that galaxies hardly change, in the time scale of the expansion of the universe. Beatrice Tinsley was one of the first astronomers to point out that galaxies do change. Here we discuss a simplified model of galactic evolution, and show that the comparison of its prediction with observations uncovers clues to how galaxies evolve with time  相似文献

Research has shown that a high level of content knowledge (CK) is necessary but not sufficient to develop the special knowledge base of expert teachers known as pedagogical content knowledge (PCK). This study contributes towards research to quantify the relationship between CK and PCK in science. In order to determine the proportion of the variance in PCK accounted for by the variance in CK, instruments are required which are valid and reliable as well as being unidimensional to measure person abilities for CK and PCK. An instrument consisting of two paper-and-pencil tests was designed to assess Grade 12 teachers CK and PCK in organic chemistry. We used the Rasch measurement model to convert raw score data into interval measures and to provide empirical evidence for the validity, reliability and unidimensionality of the tests. The correlation between CK and PCK was estimated as r = .66 (p < .001). We found evidence to suggest that while topic-specific PCK (TSPCK) develops with increasing teaching experience, high levels of CK can be acquired with limited teaching experience. These findings support the hypothesis that CK is a requirement for the development of TSPCK; proficiency in CK is, however, not necessarily associated with high levels of TSPCK.  相似文献

An important element of learning to read and write at school is the ability to define word boundaries. Defining word boundaries in text writing is not a straightforward task even for children who have mastered graphophonemic correspondences. In children’s writing, unconventional word segmentation has been observed across a range of languages and contexts with more occurrences of hyposegmentation (failure to separate two or more written words with a space) than hypersegmentation (written words are split into more than one segment). However, it is still unclear how frequent these errors are and the relationships of these written error patterns to the child’s development in oral language, spelling and reading remains relatively unexplored. To address these issues, unconventional written lexical segmentations in Brazilian Portuguese children’s text production during their first years at primary school (Year 1 to Year 3) were examined in relation to different cognitive and linguistic measures and patterns of spelling errors. Results reveal that in Portuguese the establishment of word boundaries in written text is not explained by visuospatial skills or limitations in processing resources (working memory). In contrast higher occurrences of hyposegmentation patterns were associated with lower levels of reading, vocabulary, verbal ability and morphological awareness whereas hypersegmentations were rarer and related to lower levels of reading and morphological awareness and typically only occurred in the initial stages of learning to write (Year 1). Occurrences of hyposegmentations as well as hypersegmentations were also related to spelling errors which reflected children’s poor phonological skills.  相似文献
