Research On High School Chemistry Instructional Design Based On Marzano's Taxonomy Of Educational Goals

The Chemistry Curriculum Standards for General High Schools(2017 2020 Revised Edition)clearly puts forward five core qualities,focuses on the integration of "teaching,learning and evaluation",and develops the academic quality standards.Based on the new curriculum standards,this paper studies the taxonomy theory of Marzano's educational objectives and its application in middle school chemistry teaching design,so as to implement the core accomplishment of chemistry discipline.Firstly,this paper explores the classification of Marzano's educational objectives and its application in middle school chemistry through literature survey.Then,according to the analysis of the relationship between the classification of Marzano's educational objectives and middle school chemistry,especially the content of "selective compulsory module 1theme 3",the position of its content,academic requirements and academic quality level in Marzano's two-dimensional framework is grasped,so as to better present the content and facilitate the relevant teaching design.Before teaching,set up a learning situation questionnaire.Ask students to fill in before and after class to supervise students' preview,goal setting and self-achievement test.On this basis,taking two parallel classes in the second grade of a high school in Chongqing as an example,the control class and experimental class are set up.Conventional teaching was carried out in the control class,and experimental teaching was carried out in the experimental class based on the teaching plan designed by Marzano's educational goal taxonomy theory.In the process of practice,relevant data are collected,teaching evaluation is conducted on students and teaching feedback is obtained.The results show that :1)Marzano interprets the teaching content and academic requirements,Make the knowledge present more clearly,teachers could better choose teaching strategies and implement core literacy;2)The division of self-system and metacognitive system in Marzano's two-dimensional framework enables,teacher think about teaching from the perspective of students;3)There are differences in the scores and answers to exercises between the experimental class and the control class,and the students in the experimental class are better on the whole.In general,the teaching design and practice based on Marzano's education objective taxonomy have played a certain role.
