一.开发工具简介
后端开发语言：Java 后端框架：Spring Boot(Spring+SpringMVC+Mybatis) 前端：微信小程序 数据库：MySQL 系统架构：C/S 开发工具：微信小程序开发工具
二.系统内容简介
《学生评教小程序》是一个基于微信小程序的教学质量评价管理系统，采用Java语言结合Spring Boot框架构建后端服务，前端通过微信小程序提供便捷的移动端操作界面，数据存储使用MySQL数据库，整体架构采用客户端/服务器模式。系统围绕教学评价这一核心业务场景，构建了完整的评价管理生态，包含学生信息管理、教师信息管理、班级组织管理等基础数据管理模块，支持课程类型分类和课程信息的全面管理。系统的核心功能聚焦于教师评价和课程评价两个维度，通过标准化的试题库和问卷调查机制，为学生提供多样化的评价方式，同时建立了问卷调查记录的完整追踪体系。系统还集成了留言板功能，为师生之间搭建沟通桥梁，并配备了完善的系统管理功能，确保平台的稳定运行和数据安全。整个系统充分利用微信小程序的便民特性，让教学评价工作变得更加高效便捷，为提升教学质量管理水平提供了有力的技术支撑。
