智能型数字教材系统的核心理念和技术实现

Core Ideas and Technical Realization of Intelligent Digital Textbook System

教材是实现教育目标的重要工具和核心资源。它的载体经历了从纸媒到电子介质,再到基于电子介质的教学资源集成的过程,并逐渐走向富媒体化和平台化,下一代数字教材将朝开放、个性化、社群化和智能化方向演进,智能型数字教材系统应运而生。本文通过文献研究法、实证研究法、软件工程法,厘清了智能型数字教材系统的概念、特征及其现实意义,并从知识结构图谱化、资源组织系统化、学习数据可视化、学习管理智能化四个维度提出了智能型数字教材系统的核心理念,提出了融入学习模型、教学策略模型、学习者画像和知识图谱四个核心组件的智能型数字教材系统的技术实现路径及其推进机制,以支撑不同学科教师和不同学习者的自适应学习服务需求,将教材的解读弱中介化,促进教育公平和学生学习效能的提升,以期引发教育教学模式和教育供给方式的大变革。

Textbooks are essential tools and resources to realize teaching objectives.Textbook formats have changed from paper media to electronic media,and then to teaching resources integration based on electronic media,and gradually toward the rich media and platform.The next generation of digital textbook will be open,personalized,social,and intelligent.The new format is emerging at this moment.This article analyzed the concept,characteristics,and practical significance of intelligent digital textbook system by adopting the literature research method,empirical research method,and software engineering method.We propose an intelligent digital textbook system’s core concepts from four aspects:knowledge structure mapping,resource organization systematization,learning data visualization,and learning management intelligence.We then suggest a realization method of the intelligent digital textbook system incorporating four core components:learning models,teaching strategy models,learner profiles,and knowledge graphs.It also comes up with the promotion mechanism of the intelligent digital textbook system.Intelligent digital textbooks can meet different teachers’needs as well as learners’needs for adaptive learning,weaken the interpretation of textbooks,and promote education fairness and improve students’learning effectiveness.Intelligent digital textbooks are expected to bring about significant changes in teaching mode and educational supply.
