小议如何有效进行美术色彩教学

色彩教学对于学生的美术学习有重要影响，老师在美术教学的过程中应该提高学生有效运用美术色彩的能力，这样才能使学生的作品添光增彩。然而提高美术色彩教学的有效性既是教学的重点，同时又是教学的难点，需要老师将有效的教学方法运用于课堂教学之中。     

色彩的限制与整合

课题式教学是将课程内容整合成若干课题,学生通过对课题作业的实践,来完成课程主旨的学习。"色彩的限制与整合"课题式教学从客观写生入手,到色彩的平面化处理,再到对色彩的主观构想,引导学生从对色彩的具象认识转向对色彩的抽象认识,在对课题的诠释过程中,引发出学生的个人体验,激发出学生主观构想的创造力,提高独立思考及解决问题的能力,从而建立其科学理性的思维观念。

色彩教学应把握规律,注重学生视觉感受能力的培养,通过学习色彩理论知识,提高学生对色彩的认识能力和审美意识。     

美术专业色彩教学方法的探讨

美术专业教学的色彩教学是中学色彩教学的基础,是学生对色彩认知及表现的基础教学,在教学中具有十分重要的意义。教师恰当的教学方法会直接影响学生的学习兴趣和成绩,对调动学生的学习情趣、求知的主观能动性非常重要。     

谈色彩构成的教学改革

在色彩构成教学中要明确教学目的,重视学生创新能力的培养;重视学生艺术修养的提高,增强审美意识;丰富教学手段,注重设计意识的培养。使色彩构成的学习和掌握直接关系到今后设计作品中的色彩修养和创意水平。     

关于色彩风景写生教学把握性的几点探索

色彩风景写生是美术专业教学课程中的重要环节。在今天的美术教学中色彩风景写生已成为美术创作收集素材，体验生活的重要手段，已成为有志于绘画创作的人必修的基本功。在色彩风景写生教学中学习色彩语言需要训练学生长期的观察大自然的色彩，熟悉各种颜料的性能和用法，并能从别人的色彩中丰富自己的色彩语汇。本文着意从把握色彩风景写生的训练实质；色彩风景写生的实质意义，把握色彩风景写生教学与训练的重要内涵三方面对色彩风景写生的教学的把握性进行研究。     

如何优化高中美术教学

作为中等教育之一的高中美术教学，大多采用封闭落后的临摹式教学，以及变相临摹的模仿教学.虽然有些学生的作品能够在明暗、色彩、构图等方面达到一定的水准，但这样的美术教学结果，会使学生思维形成定势.鼓励他们练习，课堂小结尽量给学生发言的机会，让学生自评、欣赏，体验创作的审美感受，在学生对课本上的范画欣赏过后，脱离课本进行创作，达到用美术语言表达自然即自我情感的能力.要求学生动手能力和表演能力的结合，可以实验画画；首先引导学生先把画好作品与实物比较，这样既认识了实物的各种形态、色彩和结构，掌握实物的基本画法及步骤，画出形象生动的作品.所以，从传统的美术教学逐步转向比较科学的以自然为师的美术教学中来，用创造性的教学改革模仿教学，提高高中学生的综合素质.     

色彩教学与美术专业学生审美能力的培养

审美能力是素质教育的重要环节，是美术专业学生重点培养的能力之一．色彩教学作为专业课之一，对学生提高审美修养和美丑的判断力有着重要意义．因此，色彩的教学不仅要加强学生色彩专业技巧的训练，还应当采用多种手段注重学生审美能力的培养，激发学生的创造热情．     

“拼”出精彩，“读”出童趣

拼音教学是学生识字的基础，也是语文教学的难点、关键之所在。如何有效地进行拼音教学，笔者通过多年的教学实践探索积累，认为采取如下策略：用色彩标识，强化视觉记忆；联系生活，进行抽象思维；借助儿歌、肢体语言等辅助手段教学，多途径的为学生开凿获取知识的通道，为语文教学打下扎实的基础。

A spatially organized representation of colour in macaque cortical area V2

Neurons responding selectively to different colours have been found in various cortical areas in macaque monkeys; however, little is known about whether and how the representation of colour is spatially organized in any cortical area. Cortical area V2 contains modules that respond preferentially to chromatic modulation, which are located in thin cytochrome oxidase stripes. Here we show that within and beyond these modules, gratings of different colours produce activations that peak at different locations. Optical recording of intrinsic signals revealed that the peak regions of the responses to different colours were spatially organized in the same order as colour stimuli are arranged in the DIN (German standard colour chart) colour system. Nearby regions represented colours of a similar hue. We found that the set of colour-specific regions formed 0.07-0.32-mm-wide and approximately 1.3-mm long bands that varied in shape from linear to nearly circular. Our finding suggests that thin stripes in V2 contain functional maps where the colour of a stimulus is represented by the location of its response activation peak.

Long-lasting sensitization to a given colour after visual search

Visual attention enables an observer to select specific visual information for processing. In an ambiguous motion task in which a coloured grating can be perceived as moving in either of two opposite directions depending on the relative salience of two colours in the display, attending to one of the colours influences the direction in which the grating appears to move. Here, we use this secondary effect of attention in a motion task to measure the effect of attending to a specific colour in a search task. Observers performed a search task in which they searched for a target letter in a 4 x 4 coloured matrix. Each of the 16 squares within a matrix was assigned one of four colours, and observers knew that the target letter would appear on only one of these colours throughout the experiment. Observers performed the ambiguous motion task before and after the search task. Attending to a particular colour for a brief period in the search task profoundly influenced the perceived direction of motion. This effect lasted for up to one month and in some cases had to be reversed by practising searches for the complementary colour, indicating a much longer-persisting effect of attention than has been observed previously.     

Extremely red Kuiper-belt objects in near-circular orbits beyond 40 AU

Kuiper-belt objects (KBOs) are an ancient reservoir of comets beyond Neptune's orbit. Some of these objects were recently found to have the reddest optical colours in the Solar System, but the number of objects for which accurate colours were available was too small for any correlation to be discerned between colour and physical or dynamical properties, which might shed light on the origin of these objects. Here we report that all nine of the KBOs in our survey on near-circular (low-eccentricity) orbits with perihelion distances larger than 40 AU have extremely red surfaces, thereby connecting an observable property with a dynamical class. Of the objects with orbital eccentricities greater than 0.1, about half are also very red, while the rest have colours similar to the Sun, meaning that reflected sunlight is not strongly modified by the objects' surface properties. In addition, of the 13 'classical' KBOs (those with semimajor axis a approximately 45 AU and eccentricity e < 0.15), the ten that are very red are in orbits with small angles of inclination to the ecliptic, whereas the three with solar colours are all in high-inclination orbits. We suggest that these three 'grey' classical KBOs may be part of a dynamical group that is separate from the 'red' classical KBOs.

Transgenic strategies for combinatorial expression of fluorescent proteins in the nervous system

Detailed analysis of neuronal network architecture requires the development of new methods. Here we present strategies to visualize synaptic circuits by genetically labelling neurons with multiple, distinct colours. In Brainbow transgenes, Cre/lox recombination is used to create a stochastic choice of expression between three or more fluorescent proteins (XFPs). Integration of tandem Brainbow copies in transgenic mice yielded combinatorial XFP expression, and thus many colours, thereby providing a way to distinguish adjacent neurons and visualize other cellular interactions. As a demonstration, we reconstructed hundreds of neighbouring axons and multiple synaptic contacts in one small volume of a cerebellar lobe exhibiting approximately 90 colours. The expression in some lines also allowed us to map glial territories and follow glial cells and neurons over time in vivo. The ability of the Brainbow system to label uniquely many individual cells within a population may facilitate the analysis of neuronal circuitry on a large scale.
