The Cognitive Diagnosis Assessment On Elliptical Learning Of High School Students Based On DINA Model

In order to build a high-quality education system and improve education evaluation standards,education evaluation and measurement are constantly being improved and developed.The emergence and development of a new generation of measurement theory provides new options for educational evaluation.Because its theory can not only evaluate the individual's macroscopic ability level,but also pay attention to the individual's micro-psychological processing process and realize the overall development of the individual.Diagnosis theory has a wide range of applications in knowledge assessment and language skill assessment in various disciplines.So cognitive diagnostic theory in various disciplines of knowledge assessment,language skills evaluation and other aspects have been widely used.In this study,the DINA model in cognitive diagnosis theory was used to diagnose the knowledge of the ellipse in the second year of high school students.The ellipse is the forerunner of learning the content of the conic section,laying the foundation for the later learning of hyperbola and parabola.The ideological method is the geometry of algebraic problem,which can cultivate the core literacy of the students' number-shaped combination.In this paper,firstly,the knowledge attribute and attribute hierarchical relationship of the ellipse are determined through the literature analysis method,with a total of 5 knowledge attributes.Secondly,according to the identified cognitive model to compile a set of test papers and make a small range of predictions,through the questionnaire method to obtain forecast data,and the use of data analysis method to test the quality of the test volume and model rationality analysis,so as to determine the test tool.Finally,350 subjects were tested,with 335 valid data,and the MLE parameter estimation method was used based on the measured data to identify and classify the subjects'knowledge status and provide a basis for subsequent teachers' targeted teaching.The main conclusions of this study are:(1)Determine the cognitive attributes involved in the ellipse in the conic section and the corresponding attribute hierarchy(2)the structure of the elliptic test volume based on the identified cognitive diagnostic model is reasonable and feasible,with high quality;(3)the use of cognitive diagnostic theory to analyze the learning ellipses of students is more detailed and comprehensive;(4)according to the cognitive diagnosis results can provide teachers with feasible teaching recommendations,the implementation of remedial teaching.
