The Research Of Information Retrieval Ability In Primary School Information Technology Course

In the 21st century belongs to the network information age,information resources plays an important role in social development,social development in the direction of informatization,education also gradually development in the direction of informatization.With the deepening of the education informationization,pay attention to the cultivation of the ability of information retrieval and information retrieval as an important part of the information technology teaching,the education of recognition and attention.In the author’s information technology education in primary school,found that there are a lot of primary school students in their spare time is never on information retrieval training,school teacher also is just good textbook knowledge,does not pay attention to the practice of training,not to mention extracurricular instruction for information retrieval.The information retrieval ability exists serious lack of elementary school students.Therefore,the loss of the ability to solve elementary information retrieval has become urgent need to solve the problem.In this paper,the core of the theory is "retrieval is learning",retrieve the learning is to point to by modern information query methods,through the student to complete the retrieval task to get the documents,information and knowledge,so as to improve their retrieval ability and the learning mode of knowledge reserves.Under the support of this theory,the selected two classes in elementary school five years practice experiments,through the case teaching,feedback learning situation,to improve practice teaching again,draw a good lesson plans,promote student information retrieval ability.The full text is divided into six parts.The first part is the introduction,the author in combing the relevant issues on the basis of the research status of both at home and abroad,combined with the contemporary to the information retrieval ability under the condition of high demand,put forward the problems of pupils in information retrieval ability,and to determine the required research methods,this paper adopts the literature method,questionnaire investigation and comparative research method to investigate the primary information retrieval ability.The second part is theoretical support part,the author first introduces the history,concept and principle of information retrieval,and various retrieval ways and means are introduced.Finally introduces the theory of retrieval is learning,that is,in this paper,the core of the theory,"retrieval is learning" is a new approach to learning,it is a kind of knowledge acquisition mode and concept.The third part,through the questionnaire and the two primary schools in the GuiLin city.Through the questionnaire survey,we found that elementary school students information retrieval ability exists serious lack of state.Main reasons,one is the backward information technology basic teaching conditions;Second,school leaders,teachers,parents,backward education idea;Three is ignored in the process of information retrieval strategy guide teachers;Four is parents of pupils with prejudice and ignore the cultivation of the ability of information retrieval and the students themselves interested in information retrieval is not strong and so on.The fourth part gives corresponding countermeasures against the front,is the main approach,on the one hand,advocating "retrieval is learning",change the teaching idea;On the other hand,to strengthen the construction of the school computer room facilities,provide good teaching conditions for the teaching;Finally strengthen the inside and outside the classroom retrieval practice guidance,improve the students’ ability of information retrieval.The fifth part is the practice process,is also the focus of this article,firstly,two primary school class as the research object of research,based on the retrieval of learning theory,combined with the students interests,to give students the corresponding retrieval assignments,students complete the corresponding retrieval operation,learn knowledge retrieval,compare the two classes of problems,and then improve the teaching process,optimizing the teaching plan,to get the best pupils information retrieval ability improving scheme.The last is the conclusion,sums up the core of the paper,and the replacement of the deficiency of the paper and in need of improvement,expect to have more education workers to participate in elementary research of cultivating the ability of information retrieval.
