Research On Teaching Strategies Of Information Retrieval In Junior Middle School "Information Technology Course" Based On PBL Mode

Information retrieval teaching is an important way to cultivate students’ information literacy,but unfortunately teachers have not paid enough attention to it.The information retrieval teaching for junior high school students is not regarded as a course,but mostly it is the content of information retrieval and storage in the information technology course.In order to improve students’ information retrieval ability and enhance information literacy,information technology teachers should use modern teaching methods to highlight students’ dominant position in learning activities,optimize the teaching process,and improve teaching effects.Firstly,this research sorts out the related research of information retrieval teaching related literature and project teaching,masters the basic characteristics and theoretical foundation of project-based information retrieval teaching.Secondly,it analyzes the teaching status and teaching status of information retrieval teaching in the junior high school "Information Technology Course" in the questionnaire.The writer investigated and analyzed the learning situation,formulated information teaching strategies based on PBL junior high school information technology courses,and selected two classes in a junior high school to carry out teaching experiments.Under the premise of controlling the variables,the information retrieval teaching of the experimental class uses project-based teaching strategies,and the control class chooses the traditional lecture and practice mode to complete the teaching.After the teaching practice,a post-test test was performed on the two classes,and the scores of the individual work and post-test were combined to calculate the student’s scores,and the learning effects were compared.The writer investigated the teaching effect of the students in the practical project teaching class,and analyzed the influence of the established teaching strategy on the students’ learning attitude and ability.According to the reseach results of the two classes of students and the investigation of the teaching effect of the students in the experimental class,project teaching has many advantages over traditional teaching,including increasing students’ learning enthusiasm,improving information retrieval capabilities,and improving information literacy.It is suggested that in order to improve the effect of information retrieval teaching,teachers should design project-based information retrieval teaching cases based on their own teaching situation.Through project teaching,improve students’ information retrieval ability and develop students’ information literacy.
