In this report, we want to touch upon two aspects of teaching mathematics in middle and high school. The first of them is the eternal question of how to teach, to motivate students and make them involved in the educational process, particularly in mathematics, where the most important factor is the natural gifts. The second aspect concerns the question which became very urgent in the modern world: what, in fact, we want to teach the students in a world over-saturated with information of any kind. As a result of the information blowup, two aspects emerge. On the one hand, straight passing over the skills and knowledge to the students becomes irrelevant today (just like a teacher or lecturer, merely speaking to an audience, who is not that relevant for young people, accustomed from childhood to perceive information through dynamic color visuals). On the other hand, there is a change in emphasis in the objective function of the educational process from gaining knowledge to acquisition of skills of working with information, consideration and estimation, and choosing of the optimal strategy of a number of possibilities. This trend can be seen in the selection of problems in the international examination PISA (Program for international Student Assessment), in the new curriculum in mathematics and in the selection of problems in the matriculation exams. These considerations (along with others) make teachers took for rtew forms of teaming, more appropriate to the demands of modernity. In this report we suggest the idea of using a mathematical competition called "Mathematical debate" (mathematical fight) as an integral part of the educational process at different levels of learning mathematics, as an appropriate tool. 相似文献

The principle of functional invariance states that it is a natural law that conscious beings with the same functional organization
have the same quality of conscious experience. A group of arguments in support of this principle are rejected, on the grounds
that they establish at most only the weaker intra-subjective principle that any two stages in the life of a single conscious
being that duplicate one another in terms of functional organization also duplicate one another in terms of quality of phenomenal
experience.

Advanced Operator Interface Design for Complex Space Telerobots 总被引:2,自引:2,他引:0
With technology advancements in computers and displays, computer interfaces can be used to alleviate the operator workload while controlling a complex robot. A graphical simulation of the robotic system can be used to improve development, train operators, and enhance their performance during actual operations. This paper summarizes the advantages realized using a graphical simulation to visually display telemetry from a multiple arm space telerobot. By displaying the commanded position of a manipulator graphically along with the actual position, the operator becomes more effective in diagnosing anomalies in the system. The negative impact of communication time delay can also be alleviated using this commanded display. The above advantages coupled with the simulation's ability to display multiple synthetic views, to move each view to any virtual location, and to highlight functions to emphasize important information, can ease the operator's workload, making him or her more effective in controlling a complex system. 相似文献

Domain experts frequently know what questions they want to ask about a data set, but they do not necessarily know the mechanisms of using an information visualization (infoVis) system for investigating these inquiries of interest. In our work, we are researching the addition of a natural language (NL) interface for bridging this gap between NL questions and data exploration within an infoVis environment. In this paper, we present our approach to integrating an NL interface into an existing infoVis system. We illustrate the power of combining direct manipulation with NL interfaces, and we provide a real-life example of applying our approach to the analysis of a large, complex data set. 相似文献

Recent learning sciences literature proposes to conceive learning as changes in the learner’s identity trajectory. In this paper, we use the analysis of dialogical positioning as a method to track down and understand shifts in identity trajectories. The Bakhtinian concepts of “polyphony” and “chronotopes” are considered as dialogical indicators of the identity positions, and are the basis of our method. A qualitative/quantitative nature is featured in this method, which is composed of three steps: a) reading of the data; b) definition of a tailored list of dialogical indicators; c) quantitative analysis. A highly collaborative, blended university course, drawing on socio-constructivist principles, was used as the context to test the method. Indeed, we believe such a course would foster dialogical identity development. All the notes posted online during the course by two selected students were used as the corpus of data. The students were selected because of their diversity in terms of level of participation and initial technology propensity. The application of the method revealed the uniqueness of the trajectories, the correlations between indicators, and their sensitiveness to the activities of the course and to the students’ personal circumstances. 相似文献

Argument Based Machine Learning Applied to Law 总被引:1,自引:1,他引:0
In this paper we discuss the application of a new machine learning approach – Argument Based Machine Learning – to the legal domain. An experiment using a dataset which has also been used in previous experiments with other learning techniques is described, and comparison with previous experiments made. We also tested this method for its robustness to noise in learning data. Argumentation based machine learning is particularly suited to the legal domain as it makes use of the justifications of decisions which are available. Importantly, where a large number of decided cases are available, it provides a way of identifying which need to be considered. Using this technique, only decisions which will have an influence on the rules being learned are examined. 相似文献

In this article, we analyze the complex rationales—both transparent to us and, at times, made visible—underneath the instructional spaces in which we work and teach. To do so, we first situate space analysis in the larger, national conversations about instructional spaces and then through the work of computers and writing scholars. We conclude with an analysis of instructional spaces at our institution. These are spaces specific to our locale, but spaces we think are quite common at most institutions of higher education. Perhaps more importantly, we situate this space analysis on issues these spaces pose—issues of restricted movement, impaired ability to collaborate, sensory disruption, limited leadership ability, and functional/material constraints. We attempt to return to the roots of hacking and to situate hacking as a particular tool for negotiating and, at times, disrupting the assumptions built under, within, and across instructional spaces. 相似文献

Business success requires that advances in technology be designed and applied within a human context. Too often technological advance has occurred without reference to human behavior. While research appreciates that electronic consumers are computer users, and vice-versa, few understand exactly how this is transforming consumer behavior. In other words, technological imagination has surpassed our knowledge of media-based consumer behavior. This paper seeks to re-dress the balance of understanding. By (i) integrating themes in human-computer interaction (HCI) with consumer behavior models and (ii) placing the results within a framework of relevant research issues, we present the conceptual foundations for a consumer interface. 相似文献
