Design And Optimization Of Junior Middle School Physics Autonomous Learning Task List

Based on the comprehensive support of emerging technologies such as big data,flipped classroom has developed into an important online learning mode in today's society.Different from the traditional teaching mode,flipped classroom is committed to promoting the development of students' independent learning ability.The independent learning before class is particularly important,and the key of independent learning is to provide each student with an appropriate task list of independent learning.Although the smart classroom has become a research hotspot,there are few researches on the design of autonomous learning task lists,and they mainly focus on theoretical researches instead of relevant experimental researches.Besides,it only pays attention to the design of the content without considering the influence of the form of the task list on students' self-study.In order to solve these problems,this research has mainly done the following two aspects for the task list of autonomous learning.Firstly,the design of self-learning task list is discussed.Firstly,the concept of autonomous learning task and autonomous learning task list is analyzed.Then,according to the task of middle school physics teaching and the characteristics of wisdom classroom,the purpose and function of the pre-class autonomous learning task are defined,and the types and functions of the autonomous learning task are given.Through the analysis of the learning characteristics of students,the design principles and strategies of independent learning task lists are sorted out,as well as the problems that need to be paid attention to when making the task lists of independent learning before class,and the sample of independent learning task lists is given.Secondly,the optimization of autonomous learning task list based on eye movement experiment.After setting the task of independent learning,what kind of way should be presented to students is also a problem of our concern.Using eye movement tracking technology,this paper studied the effect of the task list with or without illustrations and the color of illustrations(color,black and white)on the learning effect of students with different field cognition styles(field independent and field dependent).In this study,learning effects were described from two aspects: cognitive load and reading performance.Among them,the cognitive load generated by learners in the learning process chooses the eye movement index of fixation time as the evaluation standard.Combined with the eye-psychological hypothesis,through the independent sample T test of the data,the optimization suggestions on the task list are obtained.Firstly,in terms of the content organization of the task list of independent learning,illustrations have the functions of attention,guidance and cognition,which can form a close connection with the text,provide readers with a more complete information system,promote the integration of pictures and texts,and conduct in-depth information processing.Therefore,visual,intuitive and diverse learning resources should be used as much as possible in the presentation of task lists.Secondly,from the perspective of field cognition mode,field-dependent learners need to provide learning materials with more detailed information and relatively complete structure.Therefore,content arrangement can be made in different ways for students to choose,so that teaching can take individual differences into account and vary from person to person.Third,the presentation form of the task list of independent learning.In this study,it is found that the effect of color illustrations in the task list is far better than that of black and white ones,and pictures with protrude and bright details close to reality are more likely to attract the attention of learners and stimulate their interest in learning.Therefore,three-dimensional,bright illustrations with greater visual impact should be selected first in the task list.Finally,according to the optimization suggestions,the task list of independent learning is revised,and the teaching practice is carried out.Through the comparison between the experimental group and the control group,it is found that the optimization suggestions proposed in this study can indeed improve the learning effect of students,which is worthy of reference.
