To Promote The Teaching Of The The Chemical Core Concept Construct Design Research And Practice

Content abstract:The new round reform of curriculum puts forward higher request on the chemistry teachers' teaching, making each student's development as the core idea, and the ability of designing which adapts to the students of the development level is one of the compulsories. It is significant for teachers to seek a suitable approach adapting to teachers' personality and the development of students'. Chemical concept is a kind of thinking form, which reflects the chemical substance in the motion of connatural attribute and can reflect the deeply essential characteristic in the chemical process. All above play a very important role and is an important part of the chemistry course. Based on chemical core concepts for research object and a large number of investigations on domestic chemical concept teaching literature and data sorting, the paper studies the teaching design on thinking construction of chemical core concepts that can promote students during the high school stage. What's more, in order to carry out research and practice of the instructional design, the paper aims at the high school students' chemistry construction, according to the characteristic of teachers.Based on chemical core concepts for the research content in the high school stage, the paper studies the core concepts of the teaching design strategies and methods, strives to outstanding students' subject status in the study and seeks teaching methods which are more suitable for students' development, with the core concepts of principles of the chemical reaction in Book Four for the case of the teaching design.The methods of the paper are document analysis, action research, studying the new course standard, chemical materials and chemistry teaching strategy. With the author's classes to practice, teachers will reflect and summarize in the form of a questionnaire and the survey of lectures from two aspects of teachers and students.The following are the conclusions through the study:teachers should highlight the students'learning status in the process of teachers' chemical concept teaching design. Furthermore, chemical process of instructional design must take the student as the premise, and the teaching design should promote students' understandings. Besides, chemical concept teaching design should pay attention to the teaching context, whether the way to create the situation or problem situation, which will provide students with an opportunity to solve the problem independently and discover questions positively, setting a conceptual knowledge system. Owing to concepts teaching which is around chemical conceptual knowledge to launch, and the teaching design level which is decided by the holding degree on the teaching design strategies, chemistry teachers must update education concepts, and learn chemistry courses and teaching theory knowledge continuously.
