【摘要】：时代发展要求教育教学目标和教育教学环境发生改变,越来越个性化、多元化的学生学习需求以及各种新技术的运用对教师和学生的思维和技能都提出更高要求。网络教学的普及,也使得知识资源越来越丰富。新的时代要求教学工作者以下几个方面的能力提高：(1)掌握和调控学生认知水平、学习风格等学习者学习特征和需求的能力；(2)熟练运用和开发多媒体教学设备等教学工具的能力；(3)组织复杂的知识结构和课堂教学活动的能力。目前,教师教学系统设计的能力及其所获得的成效在满足学生的个性化学习需求方面还存在值得改善的地方。主要表现在：教师的教学系统设计专业知识和技能贮备不足、教师之间教学经验交流不充分、新手教师没能尽快有效的掌握适合的教学方法。本研究为解决需求与现实的矛盾,建立一个可持续管理的基于知识网络的资源库,循环利用教学资源并使之在教学活动中发挥最大效用,从而简化教师教学、增进师生交流,进一步满足学生的个性化学习需求。研究以“自动化教学设计”为主题,利用自动化教学设计的特征提取方法,探讨教师在具体教学活动中获取信息和组织教学活动的过程,通过知识库和知识语义关系模型提供个性化的教学模式以促进学生学习、简化教学设计、优化教学的效果。针对目前教学活动中专家教师和新手教师在教学设计(包括教案设计、课堂组织设计、教学资源组织等)能力和技能方面存在的差距,建立基于知识网络的自动化教学设计系统。具体而言,本研究构建了本地教学资源库和网络教学资源库、专家策略库,优秀教学案例库四个知识库。自动化教学设计系统设定用户身份为两种：教师和学生,教学设计活动开始前,系统为学习者提供知识水平测试和学习风格测试,采用所罗门学习风格测试量表作为对学生学习风格测试的具体方法和工具,并依据学习者的原有知识水平和学习风格所得的测试结果给出对应的教学策略方案。
[Abstract]:The development of the times requires that the educational objectives and the educational environment change and become more and more individualized. The diversity of students' learning needs and the use of various new technologies put forward higher requirements for the thinking and skills of teachers and students, and the popularization of network teaching. The new era requires teachers to improve their abilities in the following aspects: (1) the ability to master and control the students' cognitive level, learning style, and other learners' learning characteristics and needs; 2) proficiency in the use and development of multimedia teaching equipment and other teaching tools; Ability to organize complex knowledge structures and classroom teaching activities. Right now. The ability to design the teaching system and its effect in meeting the individual learning needs of students are worthy of improvement. The teacher's teaching system design specialized knowledge and the skill reserve is insufficient. The exchange of teaching experience between teachers is not sufficient, the novice teachers can not grasp the appropriate teaching methods as soon as possible. This study aims to solve the contradiction between demand and reality. Establish a sustainably managed resource bank based on knowledge network, recycle teaching resources and make them play the most important role in teaching activities, so as to simplify teachers' teaching and improve the communication between teachers and students. Further meet the individual learning needs of students. This paper studies the process of obtaining information and organizing teaching activities in specific teaching activities by using the feature extraction method of automatic teaching design on the theme of "automatic teaching design". The individualized teaching model is provided by knowledge base and knowledge semantic relation model to promote students' learning, simplify teaching design and optimize teaching effect. This paper aims at the gap between expert teachers and novice teachers in teaching design (including teaching plan design, classroom organization design, teaching resource organization, etc.) in current teaching activities. To build an automated teaching design system based on knowledge network. Specifically, this study has constructed the local teaching resources database, the network teaching resources database, the expert strategy database. There are four knowledge bases in the excellent teaching case base. The automated instructional design system sets up two kinds of user identity: teacher and student. Before the teaching design activity starts, the system provides learners with knowledge level test and learning style test. The Solomon Learning style Test scale is used as the concrete method and tool for the students' learning style test, and the corresponding teaching strategy scheme is given according to the learners' original knowledge level and the test results obtained from the learning style.
