【摘要】 本论文构建信息技术支持的问题化教学设计理论,并进行了相关实证。文常主要分为理论解析、模式阐释、教学实证三部分: 在理论解析部分,本文首先针对课程改革与教育信息化背景下的种种教学需求和实践现状,分析了各种关注问题的教学设计理论的主要特性、研究异同和局限性,以及信息技术促进教学变革,信息技术在教学应用中的误区和不足,从而提出构建一种新型问题化教学模式的必然性。接着,文章对关注问题的课程范式迁移趋势、面向单元的中观教学设计、体现半结构化的支架教学策略,以及信息技术支持作用等理论基础进行了分析,从而论证了构建新型问题化教学模式的可能性。由此,文章进一步对信息技术支持的问题化教学作出界定,并提出了实现问题化教学设计的系统框架和流程框架。 在模式阐释部分,文章根据问题化教学的系统框架和流程框架,分五方面来进行阐述:(1) 文章首先从主题单元的选择组织入手,分析了问题化教学的内容组织方法和教学目标表述;并接着对问题化教学中的问题设计域、不同类型教学问题的特性进行分析,从而构建了促进设计优质教学问题的设计支架,以及检验教学问题设计质量的一系列有效性特征。(2) 在环境设计章节,文章在提出问题化教学环境的全空间连续体设计理念基础之上,进一步分析了将信息化教学环境作为实现全空间理念缩影的理论意义,并指出问题化教学环境设计的最终核心聚焦在于创设问题情境和问题知情权。(3) 在过程设计章节,文章论述了问题化教学过程设计的重要性,并从教学投入性、教学任务、教学活动、助学支架等方面进行了具体深入的分析阐述:(4) 在资源设计章节,文章论述了问题化教学中的资源分布特性,以及信息化教学资源的各种作用,并提出和论述了问题化教学资源的主要应用策略;(5) 对于评价设计,文章提出应该从发展性视角来看待问题化教学评价的意义和倾向,并分析和提出了问题教学评价的设计原则和实施策略。 在教学实践部分,论文依据“模式阐释”部分所构建的问题化教学设计模式,讲解和阐述了如何依托教师专业发展和行动研究策略所展开的一系列教学实证工作,并对实证过程中所取得的数据、案例和经验进行了分析说明。 最后,论文对问题化教学设计研究作出了简要小结。更多还原

【Abstract】 This dissertation aims at constructing and giving demonstration of design theory on Problem Enriched Instruction (PEI) supported by Information technology. It consists of three parts: Theoretical study, Model elaboration and Instruction demonstration.In the part of Theoretical study, based on the study of instructional need and practical status of curriculum innovation and e-education, this dissertation analyses the characteristics and differences of various instructional design theories that focus on "problem", IT supported instructional transforming, and misapplications of IT supported instruction. Then, it explains the necessity of constructing a new design theory —-Problem Enriched Instruction. Following the above, it discusses the paradigm shift in curriculum development that focuses on problem, unit-oriented Mesoscopic instructional design, Scaffolding Learning, and functions of IT supported problem solving to conclude the feasibility and reality of Problem Enriched Instruction. Finally, it defines the ICT-supported Problem Enriched Instruction, and illustrates the theoretical framework of PEI’s system structure and designing process.Based on the PEI’s system structure and designing process, The part of Model elaboration discusses the models of PEI in five aspects: (1) The dissertation explains the organizational method of thematic unit content and the presentation of instruction objective for PEI, and analyses the design domain of instructional problem, the critical characteristics of different problems. Afterwards, it constructs the scaffolding template for problem design, and gives a series of indicators for checking the problems’ effectiveness. (2) In the chapter on environment design, it addresses the idea of "whole space" continuum for environment design, and explains the flexible function of digital environment. Based on these researches, it pointes out the core of Problem Enriched Instructional environment design is constructing the problem context and increasing the transparency of problem context for learners. (3) In the chapter on process design, the dissertation shows the importance of PEI’s instructional process design, and specifies the process of design from several important aspects, such as engagement design, task design, activitydesign, learning scaffolding design etc. (4) In chapter on resources design, the dissertation explores the distribution of instructional resources in PEI and the functions of informational resources for instruction, and demonstrates a series of strategies of resources application in PEI. (5) In the chapter on evaluation design, from the perspective of developmental evaluation, the dissertation analyses and puts forward a series of evaluation principles and practical strategies for PEI evaluation.In the part of Instruction demonstration, based on the PEI models established in Model elaboration part, it clarifies how PEI is demonstrated by instruction practice that adopted the strategies of teacher professional development and action research. And besides, it analyses the practical data, instructional cases and experience gathered during the demonstration process.In the end, the dissertation briefly summarizes the design theory of PEI.更多还原
