--2015-2016 ( i)

Course Design Week number: 2 Week

I. The purpose of curriculum design

The course of data structure is mainly to study the computer operation object and the relation and operation of the non-numerical computing programming problem. Data structure is a core course of computer science between mathematics, computer software and computer hardware, it is the important foundation of computer program design, database, operating system, compiling principle and artificial intelligence, which is widely used in various fields such as informatics and system engineering.

The data structure is learned to represent and process the objects involved in the actual problem in the computer. Through curriculum design can improve students ' thinking ability, promote students ' comprehensive application ability and professional quality improvement. This course is designed to achieve the following objectives:

n Understand and master the design method of data structure and algorithm, have the initial independent analysis and design ability;

N to master the basic methods and skills of problem analysis, System design, program coding and testing of software development process;

n improve the ability to analyze and solve problems independently by using the theoretical knowledge and methods learned in a comprehensive manner;

n Training systems and software development of the general norms of software development, training software workers should have the scientific work methods and style.

II. Basic requirements for curriculum design

1, independent thinking, complete independently: the design of each task in the course design and debugging requirements for independent completion, encountered problems can be discussed, but can not be copied.

2, do a good job on the machine preparation: Every time before the machine, to prepare the pre-commissioning procedures, carefully think about the debugging steps and the setting of the environment, prepare the relevant documents.

3, according to the specific requirements of the curriculum design set up the function module, each module requirements according to the following several content to be completed conscientiously;

These include:

A) Demand analysis:

Described in this section, the functional requirements of each module

b) Summary Design

Here is a description of the algorithm design for each section (which can be a flowchart describing the algorithm), a description of the storage structure used in each program (if you specify a storage structure, write out the definition of the storage structure.

c) Detailed design

Each algorithm implementation of the source program, for each topic to have a corresponding source program (can be a set of source programs, each function module with different functions)

The source program is written according to the rules of the writing program. To structure clear, key function of the key variables, the key function of the part to add a clear program comments.

d) Commissioning Analysis

Test data, test output results, time complexity analysis, and consideration of problems with each module design and commissioning (what are the questions?). How to solve the problem? ), the improvement of the algorithm is envisaged.

Summary of course Design: (saved in Word document) The summary can include: the course design process of the harvest, encounter problems, problems to solve the problem of the process of thinking, program debugging ability, thinking about the data structure of the course, in the course design process of the "data structure" curriculum knowledge and other content;

4, the results of each group must be checked and demonstrated, the program source code and procedures of the documentation must be submitted as part of the assessment content, (handed in a copy of each, the folder name rules are: "Study number names", such as "200413498 Gaoqui". This folder includes at least: source code, course design report, executable file. By the Learning Committee to collect the inscription in accordance with the stipulated time of the unified hand-over).
