实践与反思:新课程的"三维目标"

课程目标是课程的第一要素,而“三维目标”是新一轮课程改革所要达到的目标。深入学习和理解新课程的“三维目标”,准确把握其内在辩证关系,是新一轮课程改革持续、稳妥进行下去的关键。     

试论大学生社会责任意识的培养

大学生社会责任意识的培养,对于构建社会主义和谐社会具有重要的意义。随着国际国内形势的深刻变化,当代一些大学生不同程度地存在社会责任意识淡漠问题,如在理想追求上．重物质实惠轻理想目标;在价值取向上,重个人本位轻社会本位;在思想观念上,重自我实现轻社会责任等。从分析大学生责任意识淡漠产生的原因可知,正确地认识个人与社会之间的关系,坚持正确的道德价值导向,造就一支高素质的教师队伍等方面来加强大学生社会责任意识的培养。

高职院校扩招背景下学生学业现状及其辅导需求的实证分析

通过对扩招背景下高职学生的问卷调查,了解高职学生的学业适应、学业发展及学业情绪现状,在此基础上分析了高职学生学业适应、学业发展及学业情绪存在的问题及其产生的原因,并进一步分析学生对学业辅导的需求。在实证分析基础上指出了解高职学生的学业问题是学业辅导的前提。针对高职学生的学业辅导,要树立人人可教、皆可成才,精准辅导、各尽其才,三方联动、促进成才的辅导理念。制定高职学生的学业辅导方案要注意甄选辅导团队、优选辅导方式、精选辅导内容。     

How silicon fertilizer improves nitrogen and phosphorus nutrient availability in paddy soil?

In order to reveal the mechanism of silicon(Si) fertilizer in improving nitrogen(N) and phosphorus(P) nutrient availability in paddy soil, we designed a series of soil culture experiments by combining application of varying Si fertilizer concentrations with fixed N and P fertilizer concentrations. Following the recommendations of fertilizer manufacturers and local farmers, we applied Si in concentrations of 0, 5.2, 10.4, 15.6, and 20.8 μg/kg. At each concentration of added Si, the availability of soil N and P nutrients, soil microbial activity, numbers of ammonia-oxidizing bacteria and P-decomposing bacteria which means that the organic P is decomposed into inorganic nutrients which can be absorbed and utilized by plants, and urease and phosphatase activity first increased, and then decreased, as Si was added to the soil. These indicators reached their highest levels with a Si application rate of 15.6 μg/kg, showing values respectively 19.78%, 105.09%, 8.34%, 73.12%, 130.36%, 28.12%,and 20.15% higher than those of the controls. Appropriate Si application(10.4 to 15.6 μg/kg) could significantly increase the richness of the soil microbial community involved in cycling of N and P nutrients in the soil. When the Si application rate was15.6 μg/kg, parameters for characterizing microbial abundance such as sequence numbers, operational taxonomic unit(OTU)number, and correlation indices of microbial community richness such as Chao1 index, the adaptive coherence estimator(ACE)index, Shannon index, and Simpson index all reached maximum values, with amounts increased by 14.46%, 10.01%, 23.80%,30.54%, 0.18%, and 2.64%, respectively, compared with the control group. There is also a good correlation between N and P mineralization and addition of Si fertilizer. The correlation coefficients between the ratio of available P/total P(AP/TP) and the number of ammonia-oxidizing bacteria, AP/TP and acid phosphatase activity(AcPA), AP/TP and the Shannon index, the ratio of available N/total amount of N(AN/TN) and the number of ammoniated bacteria, and AN/TN and AcPA were 0.9290, 0.9508,0.9202, 0.9140, and 0.9366, respectively. In summary, these results revealed that enhancement of soil microbial community structure diversity and soil microbial activity by appropriate application of Si is the key ecological mechanism by which application of Si fertilizer improves N and P nutrient availability.

高校老年大学信息化教育发展思路探究

通过分析高校老年大学信息化在老年教育业务管理信息化平台功能不全面、支撑老年教育教学和管理的信息化环境基础设施薄弱、老年教育信息化标准体系缺失、符合老年人学习的信息化课程资源不足等方面问题,指出了高校信息化环境下建设好老年大学具有良好的环境优势、成熟的建设模式和资源优势,并提出在业务平台、课程资源、信息标准、大数据分析等方面的信息化建设思路,进一步深化现有"互联网+老年教育"积累的有限的教学经验和学习资源,强调新时代下办好高校老年大学信息化教育具有引领作用.     

构建动态的思想品德教学设计——初中思想品德教学设计的一种尝试

基础教育在教学过程中既强调课的“动态生成”,又要求有教学方案的预设。新编的教科书设计了形式众多的活动,目的是使教科书更贴近学生生活实际,让学生获得更多的实践体验。因此,“活动”成为思想品德课的重要教学形式,而学生的“活动”,最容易生成新的问题。为此,本文在“动态生成”教学观念的指导下,以广东版初中思想品德教材为例,探究“动态生成”的教学设计。     

关于现阶段理想信念教育问题的探讨

Reliability-based research for failure risks of ship hull girder

In order to find a simple and programmed method to analyze the reliability of hull beams when fatigue and corrosion act on ships, the stress of ships is to be calculated in compliance with the longitudinal bending and cross-section modulus of ship beams. The calculation value of stress is to be compared with the allowable stress in order to gain the actual ship load and margin of safety, and then assess the reliability and failure probability of ship beams. The longitudinal bending moment is a random variable; the fatigue and cauterization are also random variables; and as the ship is influenced by cumulative damage of fatigue and cauterization, the cross-section modulus is a time-varying random variable. The reliability and failure probabilities can be actually reflected through the reliability analysis method. The analysis results indicate that in the service time of ships, as the age of ship increases and the fatigue and corrosion effects accumulate, the reliability of ship beams decreases and the failure probability increases, especially after 15 to 20 years.
