The definitions of ‘negative knowledge’ and the studies in this regard published to date have not considered the categorial distinction Wittgenstein established between knowledge and certainty. Hence, the important role that certainty, despite its omission, should have in these definitions and studies has not yet been shown. In this article, I contrast the term ‘negative certainty’ with that of ‘negative knowledge’ in order to clarify this concept by describing its significant differences with the first. To characterize negative certainty, I base upon two criteria: on the one hand, negative certainty cannot be directly excluded by a positive certainty, and on the other hand, negative certainty must have an obvious and practical usefulness in which its negative nature is clearly appreciated. To illustrate the use of these two criteria, I describe four examples of negative certainty, paying special attention to their educational implications as well as the contrast between negative certainty and negative knowledge. 相似文献

In this article, we present the results of a research study that explores secondary students’ capacity to perform translations of algebraic statements between the verbal and symbolic representation systems through the lens of errors. We classify and compare the errors made by 2 groups of students: 1 at the beginning of their studies in school algebra and another 1 completing their studies on algebra in compulsory education. This comparison allows us to detect errors which require specific attention in instruction due to its persistence and to identify errors that disappear as students advance in their study of algebra. The results and conclusions have a pedagogic value to inform instruction and also lead to backed conjectures and research questions to push forward research on student’s translation capacity and students’ knowledge of algebraic symbolism. 相似文献

Guidance has a role to play in helping older workers to lead meaningful and fruitful lives; inside, outside, on the edge of
the labour market, or in voluntary work with examples from two very different European countries: Denmark and Spain. This
paper aims to draw attention to older workers guidance from an economic policy approach. It will be demonstrated that there
is a need for more policy making for older workers’ guidance in both countries. 相似文献

This article presents a study which aimed to explore the professional identity of early childhood teachers in Chile, applying a sociocultural approach. Relying on an exploratory qualitative design, data were collected through focus groups and photo-narratives. The findings show that these teachers understand that child-centred pedagogy is the pillar of their professional identity; that they perceive that this is under threat from the schoolification of early childhood education; and that they admit that their capacity to resist this tendency is limited to the classroom. These findings suggest that, having scarce resources available to negotiate their professional identity in their working context, early childhood teachers in Chile have a limited capacity for agency. 相似文献

A possible explanation for the numerous failures in the implementation and use of work-life balance (WLB) practices may relate to the fact that the majority of companies have introduced them without exploring the nature and extent of their founders’ or owners’ prior knowledge of WLB and WLB practices. This paper analyses the relationships between congenital learning and WLB culture and tries to identify whether WLB culture impacts on business performance through an empirical study of 229 small and medium-sized enterprises (SMEs) in the Spanish metal industry. Our findings show that in order to create positive attitudes toward WLB, managers need to create and support a learning process. These findings provide interesting insights into the drivers of organisational performance for SMEs that develop and support a WLB-supporting culture. 相似文献

This study tested a set of hypotheses derived from the model of academic achievement in mathematics of the Social Cognitive Career Theory in a sample of Argentinean middle school students. To this aim, 277 students (male and female; age: 13–15 years) were assessed using the following instruments: logical–mathematical self-efficacy scale, mathematics outcome expectations, mathematics performance goals, and mathematics ability test. All of these instruments had been adapted for use in Argentinean students. Academic achievement in mathematics (i.e., grades obtained on regular school exams) was the variable to be modeled through the path analysis technique. The analysis allowed identification of interrelations among the variables and identification of direct and indirect effects. Academic achievement in mathematics was partially explained by the model. Overall, the results support the theoretical postulates of Social Cognitive Career Theory. 相似文献

This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning (blended learning) in the UA (University of Alicante) (Spain), with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo (UNESCO (United Nations Educational, Scientific and Cultural Organization) chair for University of Management and Policy). The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers (blogs, wikis, Wimba Create (before CourseGenie), etc.), and digital platforms (Virtual Campus of the UA, Moodle, etc.) are used. 相似文献

Background: Question‐answering systems (or QA Systems) stand as a new alternative for Information Retrieval Systems. Most users frequently need to retrieve specific information about a factual question to obtain a whole document. Objectives: The study evaluates the efficiency of QA systems as terminological sources for physicians, specialised translators and users in general. It assesses the performance of one open‐domain QA system, START, and one restricted‐domain QA system, MedQA. Method: The study collected two hundred definitional questions (What is…?), either general or specialised, from the health website WebMD. Sources used by the open‐domain QA system, START, and the restricted‐domain QA system, MedQA, were studied to retrieve answers, and later a range of evaluation measures (precision, Mean Reciprocal Rank, Total Reciprocal Rank, First Hit Success) were applied to mark the quality of answers. Results: It was established that both systems are useful in the retrieval of valid definitional healthcare information, with an acceptable degree of coherent and precise responses from both. The answers supplied by MedQA were more reliable that those of START in the sense that they came from specialised clinical or academic sources, most of them showing links to further research articles. Conclusions: Results obtained show the potential of this type of tool in the more general realm of information access, and the retrieval of health information. They may be considered a good, reliable and reasonably precise alternative in alleviating the information overload. Both QA systems can help professionals and users can obtain healthcare information. 相似文献
