While the new course reform advances , often there are some deviations between new education idea and classroom instruction behavior: Classroom teachers and students " ask interdynamically --Answer " take , group cooperative formalization , probe into study is it take to suffused with ," pairs of base " goal desalinize and teaching means the person of greater importance is relegated to the background ,etc..

新一轮基础教育课程改革，是一个系统工程，是一场培养模式的变革，是一次素质教育观念的重要实践。随着新课改的逐步推进，我们欣喜地看到，教师的教学观念正在逐步更新，学生的学习方式正在得到改变，课堂充满学生成长的气息。但不可否认的是，在热热闹闹和轰轰烈烈的课改背后，透露出更多的是浮躁、盲从和形式化倾向。

Based on an analysis of 40 typical teaching plan for PE practice lesson since 1958, the author finds that the pattern, structure and design of teaching plan still remain unchanged. Therefore, the author proposes developing "Resources For Teaching Plan", transforming teaching plan from simplicity, formulism and inaccessibility into its variety, individuality and intellectuality, making effective use of "Resource for Teaching Plan".

：通过对1958年以来有代表性的40份体育实践课教案的分析，发现几十年以来教案的格式、结构、教学方案设计基本不变，针对这种现象，提出了应重视开发"教案资源"，把单一化、公式化、封闭性的教案设计向多样化、个性化、智力化的教案设计转变，以高效利用"教案资源"。

China has implemented new courses in a few years, the study of middle school teachers teaching and students studying math on the investigation at this stage Instructional Design Research expounded on the need from classroom teaching and learning theories analysis, to find guidance in the design of classroom teaching under the new curriculum theory and classroom teaching on the design analysis of the whole process; From the typical class (class mathematical concepts and mathematical theory classes and study complicated math classes, the study of mathematics learning courses, open learning mathematics classes, cooperative learning math lessons) teaching the practice of design study, initial design, this is my classroom teaching design in recent years the practice of summary, the results of this study reflect.

新课程在我国已实施好几年了，本研究通过对初中教师与学生数学教学情况的调查，阐述研究现阶段课堂教学设计的必要性；从课堂教学理论、学习理论的分析中，寻找指导新课程下课堂教学设计的理论，并就课堂教学设计的全过程进行剖析；从几种典型课(数学概念课、数学原理课、数学复习课、数学研究性学习课、数学开放探究课、数学合作学习课)的课堂教学设计的实践研究中，提出初步的设计思路，这既是本人近年来课堂教学设计的实践总结，也是本研究的成果体现。

Jiangsu is to enter a class to transform prior test division, they were summed up to teach on the foundation that approves Jiangsu name division to change practice in long-term tax with learned experience, wove history of " new course reviews special subject guides meticulously bring -- doubt · is dialytic · is chastening ", we think it meets the teachers and students that just was entered and will enter a class to change province bring surely inspire.

江苏是进入课改较早的实验区，一批江苏名师在长期课改实践的基础上总结了他们教和学的经验，精心编制了&新课程历史学习专题导引——置疑·透析·精练&，我们认为它定会给刚进入和将要进入课改省份的师生带来启发。

Basis to support this paper are very abundant. In theory there are evaluation of Scriven, constuctivism and multiple intelligence theory. Mostly act as a direction of building indexes' evaluation system; in practice, the researches of courseware evaluation methods that have been widely applied inside and outside our country to get very well practical evaluating method basis. Mostly we use multiple-parameters quantitative evaluation method which instructs evaluation methods in this paper. Most researches in this paper have two sides.

理论上，斯克里汶的评价观、建构主义理论和多元智力理论是三个强有力的依据，它们主要是在建立CAI课件评价指标体系时，起到指导作用；实践上，通过对国内外目前流行的课件评价方法的研究，获得实践性较好的评价方法依据，主要是多指标综合的量化评价方法对论文在评价方法上，起到指导作用。

Also, the essay has analyzed how to make good use of the piece of software to help make physics courseware, provided examples for thought, and covered all the unique advantages and great potentialities. At the same time, some teaching methods are suggested that physics teachers make the best use of the advantages and fight shy of the disadvantages.

文章通过分析几何画板在物理教学课件制作中的功能开发，以及对实践课例的分析和反思，全面评价了几何画板在辅助物理教学中的独特优势及发展潜力，并针对其功能上的不足，提出了运用几何画板辅助物理教学方法和建议。

Considering the restricted relationships of time, classroom, teacher and class, PCA compartmentalizes the different equivalents and processes one off scanned courses by the levels of their precedence, avoiding conflicts adjustment. The PCA system can fulfill the processing course plan in several minutes, even the condition. The application of this system which has been used for two years demonstrates the effectiveness of the system and the high efficiency of its related algorithm.

根据时间、教室、教师和班级的约束关系，进行等价类划分，依据所设定的优先级次序进行一次性扫描排课，尽量回避对冲突的调整工作，并在此基础上实现了一个课程调度系统，既适应学分制排课要求或满足教师提出较苛刻的上课条件要求，也能在几分钟内做出排课计划。2年的使用实践表明了该系统的有效性和相关算法的高效性。

Therefore, reviewing theory base on nationality ideas of Kodaly Zoltan, Karl orff and Emile Jaques-Dalcroze these three music education systems as a cut-in point, firstly use psychology, sociology and philosophy as basic theory to process macrocosmic comparative argumentation to three system music education ideas, then process microcosmic theoretic logic discursion to a few basic fields which influence sight singing and ear training course teaching aim, teaching content, teaching implementation and teaching valuation to confirm most correlative and effective information sources of teaching practice based on nation musicality of sight singing and ear training; once more describe actuality of teaching practice based on nation musicality of sight singing and ear training in our country and demonstrate these basic subjects (psychology, sociology and philosophy) with sight singing and ear training teaching relations and actual meanings of music teaching to further propose development direction and actual problems faced with teaching practice based on nation musicality of sight singing and era training in our country.

由于音乐学科教育学研究与哲学、美学、社会学、心理学、教育学、物理学、历史学、民族学等多种学科有着密切的联系和交叉，因此，从考察柯达伊、奥尔夫、达尔克罗兹(Emile Jaques-Dalcroze)三个音乐教育体系民族性理念的理论基础作为切入点，首先从宏观上对三个体系的音乐教育理念进行以心理学、社会学和哲学为基础理论的比较论证；继而从微观上对影响以视唱练耳课民族性教学的目标、教学内容、教学实施、教学评价的一些基本领域进行理论上的逻辑推理，确定与视唱练耳民族音感教学实践最相关的和最有效的信息来源；再对我国视唱练耳民族音感教学实践现状进行描述，论证这些基础学科与视唱练耳教学的种种关系及对音乐教学的实际含义，进一步提出我国视唱练耳民族音感教学实践所面临的具体问题和发展方向。
