【算法与程序设计】 穷举法与问题解决 教学设计（[] algorithm and program design method of exhaustion and problem solving teaching design） [] algorithm and program design method of exhaustion and problem solving teaching design Sun Wei, the Fifth Middle School of Beijing City The content from the address map algorithm and program design teaching unit third section second exhaustive method and problems The corresponding curriculum: curriculum standards in this section is mainly to solve problems with the method of exhaustion. Includes two aspects: 1, understand the basic concept of exhaustive method and design with enumeration algorithm. 2, according to the requirements of specific issues, the enumeration algorithm design, program to solve the problem of writing. First, teaching objectives: 1. knowledge and skills Understanding the basic idea of program design by exhaustive method. Encountered the learn to use brute force method to solve the problems in real life and learning. The understanding of the exhaustive method has a certain application. 2. process and method The basic process of experience by brute force method to solve problem. In the learning process, found that the exhaustive method rules, and to solve the practical problems in using it. The effective evaluation for the process and result of problem solving. 3. emotional attitudes and values The experience of learning through exhaustive method, information technology is a double-edged sword meaning, the use of information technology to establish the correct moral values, and the formation of the consciousness of reflection. The application of exhaustive method to guide the students to pay attention to in social life, stimulate the enthusiasm of students. The enhancement of students consciousness of cooperation, innovation and enterprising spirit. Two, analysis of the situation This section of the teaching object is high the first grade students, they have some problems in logical thinking, analysis, expression of thought ability.
