Chemistry Teaching Practice For Cultivating Students' Macro-Recognition And Micro-Analysis Accomplishment

At present,China's educational cause is constantly reforming,and we are also constantly exploring the teaching model.In 2020,China revised the "General High School Chemistry Curriculum Standards(2017 Edition)" again,which means that the current society has an urgent need for new talents,and our previous teaching models need to be changed.Under the pressure of the college entrance examination,we cannot just ask achievements and training test-oriented talents,we need to change the teaching model.Implementing the fundamental task of cultivating people by virtue proposed at the 18 th National Congress of the Communist Party of China.Training students to develop in an all-round way and become compound talents who can quickly adapt to the current environment.The author will design a teaching case from "Metals and its compounds" to practice the cultivation of the macro and micro literacy level of a high school senior one student.First of all,through literature study and analyzing the development of the core literacy at home and abroad and the current research situation of the macro to micro levels,relevant concept for understanding and definition of boundary,thus put forward the background and significance of the subject,Make clear the purpose,content and method of research.Then,under the guidance of constructivism theory and problem teaching theory,the macro and micro knowledge structure of metals and their compounds is analyzed according to the curriculum standard and the content of textbooks,and the content of textbooks is classified and innovated.This article will select sodium and iron in the first grade "Metals and Compounds" as the representative of the teaching design of metal elements,design a macro-micro-combination teaching plan from sodium and its compounds,and use iron and its compounds as the teaching practice content,using question guidance,Students conduct teaching practice in the form of inquiry,expand students' thinking in teaching,guide students to develop macro and micro,and establish students' scientific thinking.Finally,through the test papers of important iron compounds for practical testing,combined with student interviews and teacher commentary,through the analysis of the test results,we can know that through question guidance and student inquiry learning can well guide students to construct knowledge and The improvement of students' ability to use macro and micro thinking to solve problems in comprehensive applications is necessary for the cultivation of students' macro and micro thinking.At the same time,it can also provide some reference teaching design for other teachers in teaching design.
