Abstract 25
Design and Implementation of Teaching Evaluation System Based on JSP
Author: Tian Guangyi
Instructor: Wang Da
Abstract: Teacher teaching evaluation is an important part of teaching quality evaluation. With the acceleration of the process of education informatization, how to use network technology to evaluate the teaching quality of teachers in traditional teaching and how to evaluate the teaching quality of teachers in the network teaching environment is currently The difficulty of teaching management is also a key issue in the development of online teaching.
Teacher teaching evaluation is a complex systematic project that requires a lot of manpower, material and financial resources. With the help of teacher teaching evaluation system, the networked management and implementation of evaluation can be realized. A large amount of statistical data is obtained through the use of this system, which will provide a basis for in-depth analysis and decision-making.
Keywords: teacher teaching evaluation; questionnaire survey; evaluation file
Chapter 1 Introduction
1.1 The background of system development
Teacher teaching quality evaluation is a key link in teaching quality monitoring and an important means to improve teaching quality and school-running efficiency. It will play a positive role in establishing a complete teaching quality monitoring system, advancing the construction of teaching and learning styles, and cultivating well-rounded outstanding talents who adapt to the needs of the times, have innovative spirit and practical ability.
Compared with the traditional paper-based teaching evaluation method, using a system for teaching evaluation has several advantages:
1. It breaks through the limitations of the original teaching evaluation method, and can evaluate the teaching work of teachers relatively scientifically and accurately, reducing the subjectivity and randomness of scoring teaching.
2. Since the questionnaire is designed with different indicators, the results of teaching evaluation can be analyzed from different dimensions, providing more scientific and accurate data, and greatly enhancing the strength of teaching evaluation.
3. It breaks through the time-consuming and labor-consuming situation of traditional teaching evaluation. The application system can greatly reduce the consumption of academic staff and evaluators. Make evaluation of teaching more convenient and simple.
Chapter 2 Demand Analysis
2.1 System Design Method The
teaching quality evaluation system of college teachers is mainly aimed at the evaluation of teachers' teaching. The core is evaluation, which is a comprehensive evaluation through students, colleges, and teachers (peers or self).
For this system, the user requirements are:
1. Log in to the system: This requirement is a verification process for the user to enter the system. Through this function, users with different permissions can be distinguished.
2. User management: This requirement is for the management of users' personal information, permissions, etc.
3. Information entry: This requirement is the maintenance of basic information by the administrator. It is convenient for users to query and modify personal information.
4. Teacher evaluation: This requirement is the user's evaluation of teachers. It is also one of the important links of this system.
5. Statistical analysis: This requirement is the overall evaluation obtained by the administrator through systematic analysis in conjunction with the user's evaluation.
6. Query: This requirement is for the user to query the statistical results.
7. System help: This requirement is to give a detailed description of the functions of the entire system to help users quickly grasp the functions of the system and how to use it.
2.2 Requirements specification
2.2.1 Product overview
The application purpose of this system: to transform the existing paper-based evaluation of university teacher teaching to a paperless evaluation system, to realize the management of different user accounts of the system, and to complete questionnaire design, scoring, statistics, etc. The processing of these links.
System operating environment:
Software: Window 7 operating system
Visual Basic 10.0
SQL Server 2014
Hardware: Core i5 processor and above
2GB memory,
hard disk above 500GB,
display 1366*768
2.2.2 Functional requirements
The main module functions of this system:
(1) User login: This function provides user login services. The user setting function can only be accessed with the correct user password. If you use the correct password to enter the system, you can have the authority to evaluate the quality of teachers' teaching. Otherwise, it prompts an error.
(2) User management: This function is set for user management, and the main function is to add, delete, and modify users. Convenient for user management.
(3) Input information: This function is to input data. Including: student information entry, college information entry, teacher information entry. Make user information more perfect.
(4) Teacher evaluation: This function is to systematically evaluate the teaching quality of teachers. The main functions include three parts: student evaluation, college (leadership, peer) evaluation, and teacher self-evaluation. This is also one of the most important components of this system. After logging in to the interface, users can evaluate teachers themselves.
(5) Statistical analysis: This function combines the teacher evaluation function to calculate the total evaluation. Including: statistical results and query results. In the statistical results, the user can make a systematic evaluation of the previous teacher evaluations, and the total evaluation of the teachers can be obtained. In the query results, the user can browse the results of the teacher's evaluation, and can have a preliminary understanding of the teacher.
(6) System function: This function allows users to understand the system and how to use it. Including: about, help, and exit three parts of functions. About: Explains the software development tools used by the system. Help: The system introduces the application of each functional module. Exit: Exit the entire system.
Chapter 3 Outline Design
From this stage, the development formally enters the actual development stage of the software. This stage completes the general design of the system and clarifies the data structure and software structure of the system. In the software design stage, it is mainly the process of transforming a software requirement into a software representation. This representation only depicts the general overview of the software.

Chapter 4 Database Design
Database is the core and foundation of information system. It organizes a large amount of data in the information system according to a certain model, and provides the functions of storing, maintaining, and retrieving data, so that the information system can easily, timely, and accurately obtain the required information from the database.
The database logic design is to establish the table structure (that is, to define the fields (field name, type, length, etc.) in the table) and the relationship between the tables. Here, at least three rows of sample data for each table are required.
The database physical design is to actually create the database, plan the database (storage location, growth mode, access authority, etc.) under a specific database management system, and design the tables and the relationships between the tables.

Conclusion: The
three-month graduation project is about to end. In these three months, through the development of the "Design and Implementation of the Teacher Teaching Quality Evaluation System", I can further study the theory that I have learned in the book. The knowledge I learned in these three months seems to be more than the professional knowledge I learned in three years of university life. That will never really be mastered.
The three-month graduation project is actually not very long for the graduation project. Due to the rush of time, it left a little regret for my university life that is about to end, but no one is perfect, nothing is perfect. You can only do your best in everything, do not force the results. The graduation project really brings me happiness and memories in the process of my graduation project, not the result of the result.
