多载波系统中低复杂度的改进比特和功率分配算法     

许威  赵春明 《东南大学学报》2007,23(1):12-15

基于迭代的比特和功率分配机制,提出了一种低复杂度的比特和功率分配算法.与传统的迭代分配算法不同,该算法在每次迭代中只需要比较几个特定的子载波.该方法在保持传统迭代算法性能的前提下极大地减小了迭代分配算法的复杂度.此外,通过选择等功率分配方案作为初始方案加快了算法的收敛速度,进一步降低了算法复杂度.仿真结果表明,提出的改进算法在基本不牺牲系统性能的前提下有效地降低了算法复杂度.  相似文献   

Characteristics of students who benefit from high-quality mathematics instruction     

Kristie K. Jones  James P. Byrnes 《Contemporary educational psychology》2006

The present study examined characteristics of students who took advantage of the opportunity to learn Algebra II from a highly skilled teacher. In particular, student information was gathered concerning: (a) the amount of mathematics students knew prior to the class, (b) their motivation for learning mathematics, (c) the number and types of interactions they had with the teacher during class, (d) degree of self-regulation, and (e) general aptitude. A model for achievement was used that suggests both opportunity and propensity are important (i.e., students must be willing and able to take advantage of opportunity). Support for the model was found. Propensity to take advantage of a highly favorable opportunity accounted for almost sixty percent of the variance in achievement. In particular, students who were self-regulated, had strong mathematics backgrounds, and had low levels of frustration benefited more from high-quality instruction.  相似文献

中日新数学教科书中的“勾股定理”     

朱哲  张维忠 《数学教育学报》2011,(1):84-87

由于勾股定理在数学及数学教育中的特殊地位,它几乎是全世界的中学数学课程都要介绍的内容.从教科书内容的广度和深度来看,《中学数学》最难,《数学》次之,New Mathematics Counts最易;《中学数学》和New Mathematics Counts对勾股定理的发现和证明做了弱化处理;《数学》重视对勾股定理的证明,向学生展现了多元文化背景下的数学内容;3种教科书对定理的应用都很重视,都给出了一定数量的例题和习题.  相似文献

Gender differences in performance in mathematics at the end of lower secondary school in Italy     

Mariagiulia Matteucci  Stefania Mignani 《Learning and individual differences》2011,21(5):543-548

The paper deals with the investigation of gender differences in performances in mathematics for Italian students at the end of lower secondary school. The study is based on a new large-scale assessment test developed and administered by the National Evaluation Institute for the School System. Given the evidence in the literature which favors males, performances of female and male students are compared using different approaches. Scores proposed by educational experts based on item subgroups were considered, while a model-based approach was used within item response theory. The results revealed a significant advantage to males in overall performance, while no meaningful differences were observed with respect to item domain and type. An interpretable item map was developed crossing expert opinions with IRT abilities, and plausible proficiency levels were defined. According to the map-based student classification, a relatively lower percentage of females fell into the highest proficiency groups with respect to males.  相似文献

基于计算思维的任务驱动式教学模式的研究   总被引：1，自引：0，他引：1  

牟琴  谭良  周雄峻 《现代教育技术》2011,21(6):44-49

计算思维是当前国际计算机界广为关注的一个重要概念,也是当前计算机教育需要重点研究的重要课题。文章首先结合任务驱动式教学和教学模式的特点构建了基于计算思维的任务驱动式教学模型(Task-Driven Teaching Model Based on Computational Thinking,简称TDTMCT)。TDTMCT模型将教学者和学习者之间通过任务连接起来,教学过程以任务为主线,教学者主导,学习者主体。整个过程教学者运用计算思维方法准备课程,设计任务,学习者根据教学者的引导,运用计算思维方法完成教学任务。最后运用实例验证了该模型的可行性和高效性。与传统的教学模式相比较,基于计算思维的任务驱动式教学模式在培养学习者自我建构知识以及创新思维能力方面有较大的进步,不仅可以提高学习效率,而且可以培养学习者的计算思维能力。  相似文献   

What successful black South African students consider as factors of their success     

Pentecost M. Nkhoma 《Educational Studies in Mathematics》2002,50(1):103-113

Black South African students have a poor success rate in school leaving mathematics examinations. Attempts have been made to shift teachers' practices from teacher-centredness to learner-centredness, in Black schools, in order to improve the situation. So far, the attempts failed to yield the desired results. This paper reports on the findings of a study that aimed at learning from students and teachers in Black schools, as to what classroom practices lead to success in school mathematics, in their impoverished context.This revised version was published online in October 2005 with corrections to the Cover Date.  相似文献
