知识内化层次视角下的结构化互动作业设计

Structured Interactive Assignment Design from the Perspective of Knowledge Internalization Levels

作业设计历来是教学研究领域的焦点问题,在信息化教学环境下衍生出了新的内涵与标准。针对作业设计缺乏层次性与系统性的现状,通过梳理国内外作业设计及知识内化相关文献,界定引导学习者的多层次知识内化设计理念,归纳结构化作业的设计架构,并对作业的特征要素进行详细阐述。在此基础上,以教学交互理论为指导构建基础落实、积累沉淀、巩固反思、拓展探究结构化互动作业4层模型,论述随内化层次递进的知识表征形式。最后,选取编程教学中的排序算法开展单元作业教学实例。结果表明,结构化互动作业能有效提升学习者不同层次的知识内化程度,可为整体连贯的在线作业设计提供参考与借鉴。

Assignment design and practice are hot issues in the field of teaching research,and new connotations and standards have been derived from the environment of information teaching.In view of the lack of hierarchy and system in assignment design,this research defines the design concept of multi-level knowledge internalization to guide learners,summarizes the design of structured assignment,and elaborated on the characteristic elements of the assignment.On this basis,the article constructs a four-layer model of structured interactive assignment:basic implementation,accumulation and precipitation,consolidation and reflection,and expansion and exploration,then discusses the form of knowledge representation that progresses with the internalization level.Finally,the article selects the"sorting algorithm"in programming teaching to carry out unit assignment examples.The results show that structured interactive assignment can effectively enhance the internalization of learners′knowledge at different levels,and can provide reference for the overall coherent online assignment design.
