谈谈英语语法的教学方法

英语语法很难学,但是学习语法却很重要,那么怎样进行语法教学呢?笔者结合个人在教学中的体会,阐述了六种英语语法教学法。     

带有批移动方式的流水车间极小化平均流程时间的启发式方法(英文)

以极小化平均流程时间为目标的批排序问题是十分重要的,因为极小化平均流程时间等价于极小化平均在制品占用．由于这一问题属于ＮＰ－难题,不存在多项式算法保证求得最优解．基于对该问题模型结构分析,本文提出了一个新的启发式算法．计算机模拟结果表明,该算法简便且优度高．     

遗传算法编程求解TSP问题

利用基本遗传算法的思路解决旅行商问题,选择仍然采用轮盘选择方法;交叉算法采用一个启发式交叉算法,交叉位置随机,该算法以一定的概率生成一个比父代好的解,交叉概率取0.1;变异概率0.005。经多次运行,求得最优值。停止法则为循环最大遗传代数为止,另外如果30代解没有改进则停止。编程环境为Mat-lab6.5。     

改进教学方法 提高教学质量

教学方法和手段的改进是教学水平提高的一个重要因素。传统“满堂灌”式的教学方式已经不适应当前人才培养的要求。以启发式教学、案例式教学和研究型教学为代表的更切实可行的教学方法已成为目前最受青睐的教学方法。这些教学方法的交叉、综合运用可以大大增强课堂效果,提升教学质量。     

Heuristic for learning common emitter amplification with bipolar transistors

Mathematics in engineering education causes many thresholds in the courses because of the demand of abstract conceptualisation. Electronics depend heavily on more or less complex mathematics. Therefore the concepts of analogue electronics are hard to learn since a great deal of students struggle with the calculations and procedures needed. A survey was done focusing on students’ struggle to pass a course in analogue electronics by introducing a top-down perspective and the revised taxonomy of Bloom. From a top-down perspective you can create learning environments from any spot in the taxonomy using a step-by-step approach of the verbs understand and apply. Three textbooks with a top-down perspective on analogue electronics are analysed on the concept of amplifying with a transistor circuit. The study claims issues when losing the top-down perspective to present concepts and procedures of the content to be learned.     

环境经济学教学方法的实践与探讨

在环境经济学的教学实践中,综合运用多种教学方法可以达到良好的课堂氛围和教学效果。以论述案例教学法和启发式教学法的应用为主,辅以多媒体教学、网络教学方法,通过实例对这些方法进行分析和探讨。多种教学方法的综合运用作为＂投入＂,可以克服传统教学法的缺陷,有效调动学生学习的积极性,促进教与学的良性互动,引导学生独立思维,培养学生分析问题、解决问题的能力,提高环境经济学的实践性和实效性的高＂产出＂效果,达到教学效益最大化。     

Why Singapore Trumps Iceland

The article explores how a National Institute of Health policy of racialization-as-inclusion in research informs the building of Asian DNA databases at Biopolis, an emerging biomedical hub in Singapore. Citing variability in DNA and populations in the Asian region, Singaporean biostatisticians challenge DeCode Genetics of Iceland as an exemplary model of genomic research. They claim that genetic traits among populations in Asia that are relatively new to medical genomics – and being gathered ‘in the wild’ – gain value from being calculated and databased. The infrastructure deploys the ethnic heuristic in different registers. First, the network of ethnicity becomes a supple membrane coextensive with the network of genetic data points. Second, ethnicity is rendered an immutable mobile that circulates databases beyond tiny Singapore, making the infrastructure at once situated, flexible, and expansive. Third, the ethnic signifier carries affective value that enhances a sense of what is at stake in the building, mobilization and implications of such Asian databases. In short, the origami-like folding together of multiple, flowable, and perfomative data points shapes a unilateral topological space of biomedical ‘Asia.’
