在体育课中如何培养学生的学习兴趣

<正>近年来,随着新课程改革的发展,在各学科教学中教师都越来越重视学生学习兴趣的培养与提高,小学的体育教学也不例外。激发和培养学生的学习兴趣可以从很大程度上提高体育教学的课堂教学效果,所以教师要充分调动学生的学习能动性让学生爱上体育课。笔者通过近几年的体育教学实践,发现虽然小学的体育课堂教学与过去相比有了很大的变化,但是由于各种原因,仍有不少学生厌烦上体育课。所以我认为有必要与大家一起     

如何提高小学生参与体育教学的积极性

小学体育课堂教学中,教师要根据学生的性格特点进行教学设计和项目练习,要从培养学生的兴趣出发,让他们喜欢上体育课,在学习时能积极主动给地参与到教学活动中,增加学生在体育学习中的成功体验,从而提高体育教学效率,提高学生的体育综合能力。     

对小学体育教学中激励性评价的尝试

体育评价是为了全面了解学生的体育学习历程,激励学生的学习和改进教师的教学。评价无定法,激励是主流,关键看效果。小学体育课堂教学中激励性评价的实施,有利于激发学生学习体育的兴趣,提高学生的能力,培养创新意识,带来体育课堂的新变化。     

小学体育课快乐教学法探究

在小学教学中,体育是一门比较重要的学科,不仅能够让学生在体育课堂中快乐学习,同时也是可以培养学生综合能力和身体素质的课程。但是这门课程的传统教学过程和方法都比较枯燥,并且教师对体育课堂教学的重视力度不够,安排的课时比较少,而且体育课上运动量大,会给学生带来一定的疲惫感,因此,小学体育教学的成效并不可观。在这样的情况下,激发学生学习体育的兴趣,让教师教得愉快,学生学得快乐就显得尤为重要。对小学体育教学中快乐教学法的应用进行了探讨和分析。     

小学体育教学渗透德育探究

小学体育教学渗透德育是现阶段体育德育教学的重要方式,只有提升学生的学习兴趣才能保证体育德育教学的有效进行。随着我国对课程改革的不断深入,对教育提出了更高的要求,传统的教学方法已经无法满足新形势下教学的需要,体育教学不再是简单地帮助学生锻炼身体、提高身体素质的教学科目了,更重要的是在体育教学中渗透德育,提高学生的思想品德。因此,要在传统教学基础上,充分地运用多种形式的教学法,在体育教学中渗透德育,提高体育课堂教学效率。     

小学体育教学中学生竞争意识的培养

体育是一项竞技活动,竞争是体育的灵魂,没有竞争,体育活动就没有超越和发展。小学体育课上,很多体育活动都可以激发学生的进取心,促使学生参与竞争,培养强烈的竞争意识和拼搏精神。由此可见,体育教学在培养学生竞争意识上具有一定的优势。本文将从小学体育教学培养学生竞争意识的优势入手,对体育教学中培养学生竞争意识的方法进行分析。     

如何提高小学语文课堂教学的有效性

语文是学校教育的基础学科,以字、成语、词汇教学为载体,旨在培养学生的语文素养和语言组织能力。提高课堂教学的有效性是提高语文教学质量的关键。当前小学语文教学为进一步实践素质教育与新课改教学政策,必须树立学生本位的教学原则,优化课堂教学结构,因材施教,丰富教学内容,以此方式推进小学语文教学改革,最大化地提高课堂教学有效性。     

在小学数学情境教学中促进学生主动学习

小学数学教学的目标是要培养学生解决问题的能力,在课堂教学中教师如何引导学生去探索,引导学生积极主动地学习,是提高课堂教学实效的关键所在。根据多年的教学经验,主要阐述了如何在小学数学教学中巧设情境,引导学生主动学习的方法和策略,以供同行进行借鉴和参考。     

用游戏激发学习兴趣——小学体育游戏在教学中的应用之我见

近年来,体育教学中游戏法的运用越来越广泛。由于学生年龄的特殊性,小学生正处于身心发展的成长阶段,对事物都充满了好奇心,对所学的知识大多是第一次接触。用游戏法教学,保持小学生这种学习兴趣是小学体育教学取得较好教学效果的关键。这是因为它不仅可以锻炼身体,以展智力,陶冶情操,同时通过体育游戏教学可以激发学生兴趣,培养学生能力,使学生掌握体育锻炼的方法,提高自我锻炼的能力。还有一点就是体育游戏是学生特别喜爱的一个教学内容。特别是在小学、幼儿园的体育教学中,游戏更被列为基础教材,成为对学生进行体育教育的重要内容之一。     

小学体育课堂教学中低效行为分析及解决策略

在小学体育课堂教学过程中,学生的态度以及教师的安排都会影响到教学效率。因此,体育教师要做好备案工作,在教学过程中插入与本节课内容相关的游戏,为体育课增添一丝乐趣,同时有利于吸引学生的注意力,提高整个体育课堂的效率。主要分析了小学体育课堂教学过程中存在的低效行为,并针对这些行为提出了具有可行性的改进措施。     

Attempts to train goldfish to respond to magnetic field stimuli

Two different conditioning procedures, one appetitive and the other aversive, were used in separate attempts to demonstrate response to magnetic fields in the goldfish, Carassius auratus. Our results lead us to question those of an orientation experiment by Becker, although we recognize the possibility that goldfish may be sensitive primarily to magnetic field direction rather than intensity and that their directional sensitivity may be evidenced most readily by orientation in the field.     

从生态旅游到低碳旅游——从理念到实践

阐述了生态旅游、低碳旅游的基本概念,分析了生态旅游存在的不足,提出低碳旅游的量化及建立各项标准及其指标评价体系并将之融入低碳旅游全过程以实现低碳旅游的标准化,重点在于实现低碳理念、低碳参与者及低碳实践3个方面的有机结合,以促进旅游业的可持续发展的可操作性建议.     

以学定教,提高课堂教学效率

根据心理学理论,学习是一个学生内化的过程,学生是自主学会的,而不是被动教会的。因此在教学中,教师只有做到以学定教,才能有效提高教学效率,促进学生对知识的掌握。

Croppers to livestock keepers: livelihood transitions to 2050 in Africa due to climate change

The impacts of climate change are expected to be generally detrimental for agriculture in many parts of Africa. Overall, warming and drying may reduce crop yields by 10–20% to 2050, but there are places where losses are likely to be much more severe. Increasing frequencies of heat stress, drought and flooding events will result in yet further deleterious effects on crop and livestock productivity. There will be places in the coming decades where the livelihood strategies of rural people may need to change, to preserve food security and provide income-generating options. These are likely to include areas of Africa that are already marginal for crop production; as these become increasingly marginal, then livestock may provide an alternative to cropping. We carried out some analysis to identify areas in sub-Saharan Africa where such transitions might occur. For the currently cropped areas (which already include the highland areas where cropping intensity may increase in the future), we estimated probabilities of failed seasons for current climate conditions, and compared these with estimates obtained for future climate conditions in 2050, using downscaled climate model output for a higher and a lower greenhouse-gas emission scenario. Transition zones can be identified where the increased probabilities of failed seasons may induce shifts from cropping to increased dependence on livestock. These zones are characterised in terms of existing agricultural system, current livestock densities, and levels of poverty. The analysis provides further evidence that climate change impacts in the marginal cropping lands may be severe, where poverty rates are already high. Results also suggest that those likely to be more affected are already more poor, on average. We discuss the implications of these results in a research-for-development targeting context that is likely to see the poor disproportionately and negatively affected by climate change.     

Soil microbial response to herbicides applied to glyphosate-resistant canola

Adoption of glyphosate-resistant canola (Brassica napus L.) has increased glyphosate applications to this crop, and concerns have been raised about unintended consequences of these multiple applications. A field trial was conducted to evaluate the effects of pre-seed and in-crop glyphosate and alternative herbicides on soil microbial community functional structure, diversity and biomass. Pre-seed treatments were 2,4-D, glyphosate and 2,4-D + glyphosate, and in-crop treatments were glyphosate applied once, glyphosate applied twice, ethalfluralin, ethalfluralin + sethoxydim + ethametsulfuron + clopyralid, and sethoxydim + ethametsulfuron. Rhizosphere and bulk soil was collected at flowering stage of canola and analyzed for bacterial community-level substrate utilization patterns and microbial biomass C (MBC). Where differences were significant, pre-seed application of both 2,4-D and glyphosate altered the functional structure and reduced the functional diversity of soil bacteria, but increased MBC. These effects were not necessarily concurrent. The reduction in functional diversity was due to reduction in evenness, which means that the soil where both pre-seed herbicides had been applied was dominated by only few functional groups. In 1 year, two in-crop applications of glyphosate also reduced the functional diversity of soil bacteria when applied after pre-seed 2,4-D, as did in-crop sethoxydim + ethametsulfuron following pre-seed glyphosate. Even though significant differences between herbicides were fewer than non-significant differences, i.e., there were no changes in soil microbial community structure, diversity or biomass in response to glyphosate or alternative herbicides applied to glyphosate-resistant canola in most cases, the observed changes in soil microbial communities could affect soil food webs and biological processes.
