Research On The Application Of Digitized Picture In Primary School Teaching

According to psychologist Jean Piaget’s stages of cognitive developmentclassification, we get it is difficult for pupils to understand plain text. Picture, as weknow, with visual image and easy to understand, and also own other advantages. Solearners can build imago easily, improve cognitive abilities and reduce their memoryload. The digitized picture not only owns the advantages of picture, but also can makean object or event of text visualization. In the teaching process, teacher needs to usedigitized picture create scenarios and indicate a linear sequence of events about theircause and effect associations, in order to achieve a good match illustrated. Digitizedpicture becomes more and more widely used in teaching, which is an important andexplicit expression part of teaching information.Digitized picture not only can consolidate, summarize, disseminate knowledge,but also can expand the content, broaden students’ horizons, and promote the abilityof readers’ knowledge migration, divergent thinking ability and aesthetic capabilities,and so on. For digitized pictures have a strong strengthening, explaining andpromoting function in teaching. Digitized picture has unique cognitive value andadvantages in teaching, which plain text irreplaceable. But according to the study, wefound that teachers use digitized picture lack of certain logic and rules in theclassroom, which make digitized picture becomes a dispensable teaching tool andignore the function of it in teaching. Therefore, this thesis uses cognitive psychologyas a guide. The author in-depth studied the validity factors which affect digitizedpicture and the design and conduct of picture. In order to create a warm andcomfortable classroom atmosphere and expand the application of digitized picturebetter. Through analysis of the current situation at home and abroad, the digitizedpicture was uncommon applied improperly in primary schools. The reason of thissituation is lack of systematic research of the digitized pictures’ function.In this study, the author analyzes the digitized picture, defines the concept andcontent, characteristics and teaching strengths of digitized picture. The author borrows visual learning and dual coding theory to explain how digitized picture played on thelearner’s cognitive; The author also relies on information processing learning theory todesign how digitized picture as a guider; At last, the author uses multimedia learningcognitive theory to guide the usage of digitized picture on teaching applications.Digitized picture’s value was laid a foundation by these three theories in primaryschool. Analysis of the teaching problems on current application of instructionalmedia in the presence of primary school, the author gives several strategies toimprove primary school teaching. Meanwhile, the author produced a diagram abouthow digitized picture affected cognitive structure of learners; and pointed outcognitive effects that digitized picture owned. By researching the impact of cognitivestructure, memory and visual system that digitized picture brought. The authorexposed how digitized picture effected human psychology. And revealed howdigitized picture as a symbol influences on learners’ knowledge constructing. Thepaper discussed the application of the principles of digitized picture in primaryschools teaching. And the author built an application mode of digitized picture to helpteachers understand and draw. Finally, the paper selected primary science curriculum“seed (green bean) germination experiment” as a case study. The author analyzed theneeds, teaching content and learners of “seed germination experiment”. The authordeveloped a digitized picture courseware about “seed germination” by using timelinetechnology and accompanying videos and animations. It is vividly demonstrated thedifferent time periods of the seed germination of the process that bean sprouts grown.Avoiding regret of the real life, for learners can’t observe the growth state of seed allthe time. To help learners form a whole and overall concept, while it is also well toimprove the performance in the class.The organizational structure of the paper and details of each chapter are asfollows:The first chapter briefly introduces the background of this research and putsforward issues. The author sums up the significance of the existence of the studythrough access to reference domestic and foreign literatures. It reveals that digitizedpicture can enhance the learner experience and teaching effectiveness. The author also makes a simple statement about study methods.The second chapter analyzes the influence that digitized picture effects onlearners’ cognitive and psychological under the visual learning, dual coding theory;information processing learning theory and multimedia cognitive learning theoryguidance. All those based on systematic analyzing the connotation of the digitizedpicture.The third chapter explains how digitized picture makes contributions on pupils’(or children’) cognitive characteristics by according to the related knowledge ofpsychology. Including how digitized picture impacts on the learner’s cognitivestructure and effects on memory as well as the stimulation between the visual system.Taking problems of digitized picture’s application into account, the author constructsan application model of digitized picture in teaching of primary school class based onthose. The author raises application strategy and principles of digitized picture inprimary school.The fourth chapter selects a science curriculum “seed germination” experimentas a case study, which can fully and systematically describe the characteristics of thetimeline technology by showing the features of teaching content. This paper usestimeline technology to develop the design of digitized picture of “seed germination”and paints implementation process of it. At last, the author discusses the applicationmeans of courseware in teaching.The fifth chapter summarizes the main achievements and deficiencies of thisthesis. A reasonable evaluation and reflection is given about exist problems of theresearch. And making a clear plan or direction and prospecting for future research.
