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

Educational goals are the starting point and destination of teaching activities,and clarity and perfection of educational goals have a good guiding role.To implement Lid's educational philosophy of fostering people and cultivate students' core literacy in chemistry,the key link should be implemented in classroom teaching.At present,confined to various factors such as teaching resources and teacher abilities,the Fuzzification of educational goals has brought obstacles to the implementation of teaching goals.This article takes Bloom's taxonomy of educational objectives as the theoretical framework,and combines the subject2 of the compulsory module in the new curriculum standards of general high school chemistrycommon inorganic substances and their properties.Proceed from four perspectives and clarify the target requirements.First,understand the knowledge dimension and cognitive process dimension of taxonomy fromthe perspective of chemistry;secondly,use Bloom's educational objective taxonomy to refine the content requirements of the new curriculum standard theme2;then use Bloom's educational objective taxonomy to refine the content of the new textbook Teaching goals;Finally,use Bloom's taxonomy of educational goals to refine the academic quality evaluation of the new curriculum standards.In order to achieve the integration of teaching,learning,and evaluation,three different lesson plans and diagnostic test questions were designed with the refined teaching goals as the guide,and then practiced in the practice school.The research found that the following conclusions can be drawn:(1)The content requirements of the refined theme 2,the teaching objectives and quality evaluation standards of the PEP textbooks,the overall direction of the three are unified,but the content requirements emphasize the selection of content,The quality evaluation standard focuses on the choice of teaching methods,and the teaching goals can combine the two organically.(2)Current course content,"metacognitive knowledge" the proportion is relatively small,and the knowledge of "evaluation" and "creation" is relatively small.(3)After adopting detailed teaching cases,students feedback that the efficiency of listening to lectures has been significantly improved.The refined teaching objectives have a strong guiding nature,and teachers can form the consistency of teaching,learning,and evaluation in the teaching process.
