INTRODUCTION The Yang-Baxter equation(Yang,1967;Baxter,1972)is one of the most valuable concepts in modern theoretical physics(Baxter,1982).The importance of detailed study of Yang-Baxter equation solutions is due to its key role in constant solution models of sta-tistics mechanics(Baxter,1972;1982)and field the-ory in lower dimensions(Yang,1967),conformal field theory(Di Francesco et al.,1997)and in quan-tum integrable systems(Faddeev et al.,1990).From the group-theoretical viewpoint… 相似文献

In anatomical education three-dimensional (3D) visualization technology allows for active and stereoscopic exploration of anatomy and can easily be adopted into medical curricula along with traditional 3D teaching methods. However, most often knowledge is still assessed with two-dimensional (2D) paper-and-pencil tests. To address the growing misalignment between learning and assessment, this viewpoint commentary highlights the development of a virtual 3D assessment scenario and perspectives from students and teachers on the use of this assessment tool: a 10-minute session of anatomical knowledge assessment with real-time interaction between assessor and examinee, both wearing a HoloLens and sharing the same stereoscopic 3D augmented reality model. Additionally, recommendations for future directions, including implementation, validation, logistic challenges, and cost-effectiveness, are provided. Continued collaboration between developers, researchers, teachers, and students is critical to advancing these processes. 相似文献

This article offers an overview of mathematics education in Spain, analyzing the production of PhD theses over the last 30 years.
This period has been divided into four cycles that describe the evolution of Spanish research in the field of mathematics
education, together with changes in university and social politics. This paper also includes a forecast of the number of theses
that will be produced over the next 7 years, thus predicting the future progress and development of this area of research. 相似文献

The goal of the present study was to evaluate the effectiveness of the Auditory Discrimination in Depth Program (ADD) in remediating
the analytic decoding deficits of a group of severe dyslexics. A group of ten severely dyslexic students ranging in age from
93 to 154 months were treated in a clinic setting for 38 to 124 hours (average of 65 hours). Pre- and post-treatment testing
was done with the Woodcock Reading Mastery Test and the Lindamood Auditory Conceptualization to assess changes in phonological
awareness and analytic decoding skills. Results revealed statistically significant gains in phonological awareness and analytic
decoding skills. 相似文献

The power of the chi-square test statistic used in structural equation modeling decreases as the absolute value of excess kurtosis of the observed data increases. Excess kurtosis is more likely the smaller the number of item response categories. As a result, fit is likely to improve as the number of item response categories decreases, regardless of the true underlying factor structure or χ2-based fit index used to examine model fit. Equivalently, given a target value of approximate fit (e.g., root mean square error of approximation ≤ .05) a model with more factors is needed to reach it as the number of categories increases. This is true regardless of whether the data are treated as continuous (common factor analysis) or as discrete (ordinal factor analysis). We recommend using a large number of response alternatives (≥ 5) to increase the power to detect incorrect substantive models. 相似文献

The study reports the results of a questionnaire on the opinions of biology, medical and agricultural students regarding the nature of the contribution of high school biology to their study of biology in the university. It was found that most students value the contribution of high school biology to their learning, understanding and retention of new material. Students who specialized in high school biology and who studied an inquiry-oriented program in high school had definite advantages over the others. High school experiences were found to influence achievement in college biology to the extent to which the university courses were based upon prior knowledge. 相似文献

This article compares the views of Mikhail Baktin and Jean-François Lyotard on difference and diversity. Both philosophers elevate diversity on a higher level, considering it to be a fundamental fact of human existence rather than a temporary and superficial phenomenon. However, while Lyotard emphasized the depth of differences amongst various discourses and language games, Bakhtin thought of diversity as a form of connection. Lyotard envisioned a multitude of separate and internally coherent discourses, while Bakhtin traced diversity within each discourse as well as among them. The Baktinian notion of the polyphonic truth helps to move diversity from an abstract goal into a working part of the educational enterprise. 相似文献

ABSTRACTSchool psychologists report a desire to increase consultation with teachers but are limited by competing job demands. Consultation via videoconference (i.e., teleconsultation) offers one possible means of increasing consultant availability to teachers, but little is known about the acceptability of this technology in actual practice. In this exploratory study, we conducted an online survey to assess the conditions under which school consultants would use teleconsultation to assist teachers remotely. Sixty-two school psychology practitioners, trainers, and trainees completed a choice-based conjoint survey designed to assess teleconsultation acceptability in the context of varying commute times, consultee comfort levels, and student problem severities. Findings suggest important differences in teleconsultation acceptability in the context of real-world tradeoffs. Implications of these results are discussed, as well as the potential for using conjoint analysis to better understand technology decisions among school consultants. 相似文献

特种钢丝绳隔振器静态实验研究 总被引:1,自引:0,他引:1
在分析航空发动机外部管路的工况和结构特点的基础上,设计了适合在发动机外部管路支承中使用的类似于悬臂梁结构的钢丝绳隔振器,并对其进行了静态实验研究.静态实验中得到不同结构参数钢丝绳隔振器的滞迟回线、刚度变形幅值关系曲线和能耗系数变形幅值关系曲线.通过分析表明:钢丝绳隔振器呈现明显的滞迟特性,隔振器的刚度、阻尼等性能随变形幅值变化表现出明显的非线性特性,同时,通过改变钢丝绳的结构参数,可以获得具有不同性能的钢丝绳隔振器,以满足不同工况的需求.研究结果对钢丝绳隔振器在航空发动机外部管路中的应用具有重要参考价值. 相似文献
