The Eye Movement Research Of Middle School Students’ Chemical Insight Problem Solving

Through the definition of insight problem solving and the review of insight problems,this study found that insight problems are relatively short and concise and require few steps to solve,but it is difficult to obtain accurate results.Therefore,organic inference questions are determined as test questions in the field of subject chemistry.According to the literature,the types of organic inference questions are sorted out,and the test questions are prepared through qualitative screening based on the framework.Test questions are issued to 225 students in the four classes of the second grade of E Middle School in L City,and the recovery data adopts Winsteps of the Rasch model.The software conducts quality inspection and optimization,determines 6 questions of experimental materials,and prepares prototype questions corresponding to the whole as eye movement experimental materials.Afterwards,the eye movement experiment design was carried out.This part is divided into two parts:using eye tracking technology to conduct 3(academic level)*2(with or without prototype inspiration)two-factor experiments on 36 students and 3(question type)*2(with or without prototype inspiration)two-factor mixed experiment on 24 students in the second grade of B high school in C city,the dependent variable is an eye movement indicator,after the experiment,a retrospective oral report and interview and the PAAS self-evaluation scale are filled in.Finally,sort out and analyze the experimental data.Analyze the difference in information processing through the total test time,total fixation duration,number of fixation,eye movement diagram and oral report;through the total fixation time,fixation times,pupil area standard deviation(Pupil area std dev),average fixation duration in the interest area,and PAAS score analyze the difference in cognitive load;the difference in attention distribution is analyzed by the Percent time fixated related to time in the interested zone and the eye movement heat map.Through the analysis of experimental data,the research conclusions:(1)Prototype enlightenment has no obvious difference among premium students,and can identify key information faster.Even without the prototype problem learning process,the time to solve the problem is shorter and the thinking process is complete.Able to examine and reflect;the cognitive load is small;the attention to the key information interest area is the greatest in attention distribution.(2)Prototype enlightenment differs greatly among medium students,and they rely more on prototype questions than premium students and students with learning difficulties.Problem-solving is obviously smooth when inspired by prototypes.Able to grasp the key information,but the information processing speed is slow,unable to examine and reflect on each question,but has a sense of self-monitoring;the cognitive load is large;the attention to the key information area ofinterest in the distribution of attention is medium.(3)Prototype heuristics are different among students with learning difficulties,relying on prototype questions,able to identify key information,but the information processing is invalid,the test time is long,but there are more questions abandoned;overall,the cognitive load is large,pay attention to the distribution of interest in key information.And they have low attention to key information areas of interest.(4)In the chemistry insight problem under the"organic inference" question type,after the prototype question is studied,premium students are less likely to produce insight thinking,students with learning difficulties can produce insight thinking,and medium students are most likely to be inspired by prototype questions to produce insight thinking.(5)Among the three types of test questions in the research,the information transfer question is most influenced by prototype inspiration,followed by calculation inference questions,and there is no big difference in the property inference questions.Based on the research conclusions,combined with existing research and later interviews,the corresponding student learning and teacher teaching enlightenments are obtained:(1)Pay attention to the accumulation of knowledge and consolidate basic skills;(2)Improve the cognitive structure and cultivate insightful thinking(3)Carefully create problem situations to activate insight thinking;(4)Use diversified academic assessment tools;(5)Stimulate learning motivation and improve insight drive.
