A Study On The Determination Of Chemical Cognitive Disorder In High School Students Based On Cognitive Structure

Modern cognitive psychology believes that learning is the process of forming a cognitive structure in the human mind through certain steps and procedures.However,due to the influence of certain factors in the process of constructing cognitive structure,it hinders the further construction of cognitive structure,leading to the formation of cognitive disorder.The existence of cognitive disorder will inevitably affect the construction of students' knowledge and restrict their achievement.Therefore,looking for students' cognitive disorder in the learning process is a necessary measure to help students improve their learning effect.In this study,the literature method,interview method and flow map method were used to study the cognitive disorder of high school students in learning "iron and its compounds".By reviewing the current methods of measuring cognitive structure and the current status of cognitive disorder research,it is found that students' cognitive disorder can be investigated from the perspective of cognitive structure.Based on this,the use of interviews to investigate students 'knowledge of the knowledge content of“ iron and its compounds ”;converting interview audio materials into textual materials,and the flow map of the students' cognitive structure is drawn to analyze the variables and information handle strategy of the students 'cognitive structure and knowledge contents.According to the cognitive structure variables of students,it is found that the width,richness,and integration of cognitive structure of eugenic students are higher than that of middle and lagging students,there are fewer misdescriptions,and the information retrieval rate is higher;the variable of cognitive structure of middle students is better than that of lagging students overall.Compared with middle and lagging students,the eugenic students are better at using higher-level information processing strategies,followed by the middle students,and the lagging students last.According to the analysis of the knowledge content of cognitive structure,students' cognitive disorder in "iron and its compounds" mainly include:(1)The general physical properties of metals are extended to the physical properties of specific metals,with the focus on the color of iron;(2)Judgment of the reaction product of iron,ferrous oxide and oxidant,the emphasis is on clearing the strength and weakness of the oxidant;(3)The difference between the reaction of iron and different acids,theemphasis is on distinguishing oxidizing and non-oxidizing acids;(4)Iron The essence of the reaction with the salt,clarify the role of the redox reaction;(5)various types of iron oxides are commonly known;(6)the difference between dyes and coatings;(7)the composition of Iron tetroxide.According to the students' cognitive structure disorder and information processing strategies,the following strategies for solving cognitive disorder are proposed:(1)focus on the breadth of knowledge;(2)strengthen the structure of knowledge;(3)ensure the accuracy of knowledge;(4)information processing The choice of strategy;(5)Cultivating metacognitive ability.
