Paper Keywords: Information and Computing Science; Practical curriculum system; reform in education

1998 the Ministry of education merged the majors of computational mathematics and its application software, information science and operational research, cybernetics from the original mathematics category to form the "information and computational science specialty", and its establishment has played a great role in promoting the personnel training and research of information science in China. This major is a science major which includes information science, computing science, operation and control science. At present, there are many schools offering this major, but most of them are offering mathematics major for the first time. Except for a few colleges with mature experience, most colleges have not yet formed their own characteristics. Therefore, in recent years, many colleges and universities have seriously and responsibly discussed and reformed the major issues of information science, such as professional connotation, talent training mode and curriculum system, with a view to running their own characteristics and passing them on to the society.

First, the problems that restrict the practical teaching quality of information and computing science specialty at this stage.

The major of Information and Computing Science is a new major. Although there are some understandings about the professional connotation, personnel training mode and curriculum system, the research on practical teaching is relatively backward. The practical teaching of Information and Computing Science is generally based on the original mode of other mathematics majors or engineering majors, which is far from the national requirements for personnel training of Information and Computing Science. At present, it is difficult for college graduates in China to find jobs, especially those majoring in information and computing science. The main reason is that students' comprehensive practice and practical ability are poor. Therefore, it is very necessary to systematically reform and optimize the practical teaching of information and computing science, build a practical teaching system to meet the needs of economic and social development, and cultivate innovative talents.

The whole process of many practical teaching lacks systematic and overall design and arrangement, and teachers of various courses have their own ways to deal with practical links. The practice content, teaching mode and assessment method have not been scientifically demonstrated and reasonably standardized, and even some vital practice links have been simply omitted, which leads to the decline of students' understanding and application ability of the theoretical knowledge they have learned.

The number and knowledge structure of teachers can not fully meet the needs of practical teaching under the new situation, and the training of dual-qualified talents needs to be further strengthened.

Second, the ideas and measures of practical teaching reform of information and computing science specialty

1. Improve the practical curriculum system and realize the training characteristics of applied talents.

First of all, starting from highlighting the characteristics of applied talents, we should reform the traditional teaching system of research-oriented talents, so that students can deepen their understanding of theoretical knowledge, master the basic theory and latest technology of data analysis and processing, make better use of advanced calculation methods and tools, and improve the research and development ability of application software and numerical software. Therefore, the teaching content of practical teaching system is divided into three modules: mathematical modeling ability module, computer application ability module and scientific computing ability module.

(1) Mathematical modeling ability module. The traditional mathematical teaching mode is mainly to teach mathematical theory, and the idea of mathematical modeling runs through practical teaching, so that students can not only master the theoretical knowledge of mathematics, but also understand and recognize it through the application of mathematical models. This is a good teaching reform. This module focuses on cultivating students' ability to build and solve mathematical models, so as to further develop students' ability to use mathematical knowledge to solve practical engineering problems, let students actually experience the application of mathematical theory in engineering, and cultivate students' innovative consciousness and ability to solve problems independently. Therefore, mathematical modeling courses, mathematical modeling course design and mathematical modeling competition training courses are set up to guide students to participate in mathematical modeling competitions and cultivate students to apply their knowledge to social practical engineering and management. In recent years, he has won the first prize 1 time in the national mathematical modeling competition for college students, the second prize 6 times, and the first prize 7 times in the Shanghai mathematical modeling competition for college students.

(2) Computer application ability module. In addition to cultivating students' good mathematical literacy, information science majors should also have strong computer application ability and be able to use their knowledge and skilled computer skills to solve practical problems. Therefore, the cultivation of computer application ability runs through the whole teaching process. Through the strengthening of practice system, students' application ability has been greatly improved and they are highly competitive.

(3) scientific computing ability. Through the course design of "Numerical Analysis and MATLAB Application", "Data Analysis" and "Mathematical Experiment", the students' analytical ability and comprehensive application ability of algebra and geometry knowledge are further improved, and the students' ability to fully use their mathematical knowledge and computer mathematics software to solve practical engineering problems is cultivated, which improves their application ability and lays a solid foundation for cultivating high-level students.

2. Reform the content and means of practice teaching, and combine theory teaching with practice teaching closely.

First of all, in order to better combine theoretical teaching with practical teaching, attention should be paid to the connection between practical courses, such as computer application training, programming training, data analysis, numerical calculation, database application training, etc., all of which have corresponding theoretical courses. Practice course is not only the demonstration and application of theoretical course, but also the expansion and extension of theoretical course. In practice, every year, the teaching content will be adjusted according to the needs of enterprises, society and hot issues, so as to run better.

Secondly, teachers operate in the form of curriculum groups. The teachers of theoretical courses and practical courses are in the same course group, or some practical courses are held concurrently by the teachers of theoretical courses. In this way, enough teachers can be gathered in each direction to concise the research direction, and the content of curriculum design can be determined. Through the collective research of teachers in the curriculum group, the design tasks and requirements are put forward and announced at the beginning of the semester, so that students can clearly understand the practical problems that need to be solved before learning the theoretical course and in the subsequent learning process.

At the same time, in the whole practice process, we should attach importance to the cultivation of students' practical ability, the guidance and control of the practice process, actively build a teaching model with students as the main body and teachers as the auxiliary, and explore the teaching method with inspiration as the core. For example, the whole internship course of programming training lasts for 40 hours, and only 8 hours are arranged for theoretical teaching. The remaining 32 hours require students to concentrate on completing their own works on the computer, and teachers can inspire, guide and guide students at any time according to their' problems'. The assessment method also attaches importance to the practical process. The evaluation consists of four parts: ordinary grades, student reports, student works and defense. At the same time, students learn teaching materials or related materials by themselves, with the cooperation of peers and the help of teachers to complete the project. This teaching form is suitable for content with strong application, strong interest and appropriate difficulty. Practice has proved that this teaching strategy is very effective in cultivating students' operational skills, cognitive ability and innovation ability.

3. Establish an information management platform to control the practice teaching process.

First of all, through the construction of information management platform, further revise teaching documents such as syllabus, plan and task book; Write or modify instructions or handouts; Carry out curriculum construction, multimedia courseware production and other work; Realize the whole process control and management of graduation thesis; Improve teachers' ability to apply modern information technology; Promote the continuous application of advanced modern technologies such as network, electronic courseware and multimedia equipment in teaching activities. Rich auxiliary teaching methods make the classroom no longer a simple blackboard writing and teacher teaching, and the whole teaching process is more vivid, interactive and enlightening. The technical content and knowledge of the classroom have been greatly improved, and the teaching quality has been significantly improved.
