信息检索能力层次模型及实验教学方案

Hierarchical Model of Information Retrieval Ability and Experimental Teaching Scheme

为在教学过程中切实提升学生信息素养和检索能力,本文引入心流学习理论,提出了让学生在心流通道内完成任务的理论模型和操作方法。把信息检索课程的教学内容和任务目标根据挑战和技能需求分成不同的层级阶梯,课程目标要求和能力需求两个维度的层次共同构成了信息检索课程能力要求的层次模型。该模型可以用于指导课程的教学内容设计和教学实施过程,提出了让学生在心流通道内完成实验任务的理论模型和操作方法。设计实验方案需要考虑目标实现的主体、客体、媒介等因素。反馈方面考虑实验过程即时状态和实验最终结果状态。实验内容分成3种类型,分别是基础性实验内容、方法性实验内容和资源性实验内容。依据该方案实施实验教学活动,能有效地调动学生掌握文献检索的相关知识的主观能动性,促成主动学习,有利于提升学生综合运用文献信息资源的能力,从而有效提升学生信息素养和检索能力。

In order to improve students’information literacy and retrieval ability in the teaching process,this paper introduces the theory of flow learning,and puts forward a theoretical model and operation method for students to complete tasks in the flow channel.The teaching contents,tasks,and objectives of information retrieval course are divided into different levels according to the challenges and skill requirements.The level model of the ability requirements of information retrieval course is composed of the two dimensions of curriculum objectives and ability requirements.This mode can be used to guide the design of teaching contents and the implementation of teaching process.This paper also puts forward a theoretical model and operation method for students to complete experimental tasks in the flow channel.The design of experimental scheme needs to consider several factors(e.g.,subject,object,and media)to implement the objective.The feedback needs to consider the real-time state of experimental process and the state of final experimental result.The experimental contents include three types,i.e.,basic experimental content,methodological experimental content,and resource related experimental content.The implementation of experimental teaching activities according to the scheme can effectively mobilize the students’subjective initiative of mastering the relevant knowledge of literature retrieval,promote active learning,and improve students’ability to comprehensively use literature information resources,so as to effectively improve students’information literacy and retrieval ability.
