中等教育美术专业色彩教学与教法新论

色彩教学在中等职业学校美术教学中与素描教学一同被认为是美术基础教学的主要科目.色彩教学在当今课堂实践中采取什么样的方法直接关系到此门课程的成功与否,其关键在于继承传统的教学模式并在此基础上提出富有当代思维意义的教学方式.阶梯式的教学方法是色彩教学的关键所在.每一时期循序渐进的阶梯教法在开发学生艺术思维方面会起到良好的效果.单色即素描关系训练法、固有色与环境色训练、色调及意向表现训练法三种课堂训练方式是从理性教学到实现色彩情感收效的三个步骤.而教学与教学手段的创造性运用将是保障学生掌握色彩的一般规律,加深理解色彩的艺术奥秘,提升色彩的认识高度的有效途径.本文将在专业训练法与教学辅助手段两个方面详细论述.     

通过模式进行CIM到PIM的模型转换

Model driven architecture （MDA） is an evolutionary step in software development. Model transformation forms a key part of MDA. The transformation from computation independent model （CIM） to platform independent model （PIM） is the first step of the transformation. This paper proposes an approach for this transformation with pattern. In this approach, we take advantage of ＂reuse＂ from various standpoints. Feature model is used to describe the requirement of the application. This can help us bring ＂reuse＂ into effect at requirement level. Moreover we use pattern to transform CIM to PIM. This can help us bring ＂reuse＂ into effect at development level. Meanwhile, pattern was divided into four hierarchies. Different hierarchies of pattern are used to help us utilize reuse at different phase of development. From another standpoint, feature model describes the problem of a domain while pattern describe the problem across domains. This can help us reuse the element in and across domains. Finally, the detailed process of the transformation is given.
