To solve the problems of the original Coati Optimization Algorithm with low exploration ability, insufficient exploitation ability and easy to fall into local optimum, an improved coati optimization algorithm based multi-strategy is proposed. Firstly, the initial solution traversal is improved through Circle chaotic mapping to lay the foundation for global search; secondly, the local optimum is jumped out through Lévy flight to improve the global search ability of the algorithm; finally, the performance of the proposed algorithm is evaluated using numerical analysis and convergence analysis in comparison with four algorithms such as PSO and WOA. The experimental results show that the algorithm in this paper has better search accuracy and convergence speed and has better performance in solving high-dimensional problems.
Cao Yu is one of China's leading playwrights,with classics such as Thunderstorm,Sunrise,Field,Peking Man and Home.The poetry in Cao Yu's classic plays has been the focus of academic re-search,and the image research directly related to it should not be ignored.If we can give the definition of universal image,natural image and human image to Cao Yu's classical plays,then,studying the artistic techniques of symbols,hints,metaphors,renderings,unity of opposites,concatenation of simple meanings and superposition of double meanings in classic plays of Cao Yu seems to be helpful to better understand Cao Yu's understanding of fate and the world around him,and can also understand the unique artistic charm of classic plays of Cao Yu more effectively.
This study had the purpose of testing two methods for teaching grammar in English as a Foreign Language (EFL) class: the deductive and inductive approaches in terms of effectiveness and rapport.This research was conducted in a public high school in Ecuador.Seventy students enrolled in the second year of senior high school participated.One in-service teacher taught the EFL classes during the process of intervention (10 weeks), and two EFL teachers observed all of these classes and recorded the information by filling in observation sheets.The students were administered grammar pre-tests and post-tests in order to assess their grammar knowledge.The results of the tests showed a significant difference in the scores in favor of the inductive approach.After the statistical analysis of the data obtained from the tests and observation sheets, we concluded that the inductive approach is more effective for teaching grammar in the EFL classroom in terms of instruction and rapport.
本研究在国内外相关文献的研究基础上，历时三个月的教学实验，结合调查问卷和访谈法，以师生合作评价理论和《新课标》具体要求为指导，验证了师生合作评价模式（TSCA）能有效提升初中生英语总体写作能力及在语言、结构、书写和内容等方面的分项能力；实验班学生对此教学方法持积极认可态度。基于此，本研究提出初中英语写作教学相关建议：重视课前准备，挑选典型样本；科学设置标准，层层深入递进；注重课后反思，强化评价效果；精选学生佳作，重视激励机制；合理划分小组，促进写作共同体。
段落是文本主题信息的有效载体。段落解析可成为学生阅读思维的触发点。当前阅读教学中，教师忽略基于段落的文本解析和实践，不利于学生阅读技能的训练、阅读策略的掌握和阅读思维的形成。本文从结构、意义、功能和语用四个角度探讨了基于段落解析的可行性策略和途径，旨在实现学生对文本内涵的深层理解，进而发展学生的阅读思维。
