Research On The Experimental Teaching Practice Of High School Chemistry Based On "Scientific Exploration And Creative Consciousness"

The new curriculum standard proposes that the teaching of middle school chemistry should focus on the development of core literacy in chemistry,and that chemistry experiments are an important activity to cultivate students' "scientific inquiry and innovative consciousness" literacy.It is particularly important to study how to give full play to the value of chemistry experiments.To cultivate students' core academic literacy through chemistry experiment teaching,it is necessary to establish the internal connection between chemical experiment and teaching strategies and "scientific inquiry and innovative consciousness".Based on the content of chemical experiments,through effective chemical experiment teaching strategies,the content of chemical experiments contextualization,concreteness and structure,thus promoting the real implementation of "scientific inquiry and innovative consciousness".This article selects three "scientific inquiry" experiments in the chemistry course 1 of the People's Education Edition as the carrier,carries out "literacy-based" teaching design,and explores effective experimental teaching strategies to cultivate students' scientific inquiry ability and innovative consciousness,with a view to serving as senior high school chemistry experiment teaching.Cultivate students' "scientific inquiry and innovation awareness" to provide teaching case and teaching ideas.The thesis mainly includes the following four aspects:(1)Through the new requirements of the new curriculum standards for chemical experiments and literature research,to understand the research status of chemicalexperiment teaching under the background of core literacy,so as to establish the research background and research significance.Based on the case analysis of "scientific inquiry and innovation consciousness" combined with specific chemical experiments,determine the feasibility and research value of this research,and then formulate research ideas and research methods;based on in-depth analysis of literature and research content,scientific inquiry and innovation The concept of consciousness is defined;according to the teaching characteristics of chemistry experiments and the characteristics of cognitive development of high school students,the research theoretical basis of this article is determined.(2)Through questionnaires and interviews to understand the current status of chemistry experiment teaching in frontline teaching and the current status of "scientific inquiry and innovative consciousness",summarize the existing problems,and determine the teaching practice research based on the actual situation of the school.Teaching strategy: carry out "literacy-based" teaching design;use science history,life phenomena and chemical experiments to create different teaching situations;carry out a variety of chemical experiment types such as group experiments,innovative experiments and extracurricular interest experiments,so as to improve the students' level of "scientific inquiry and innovation awareness."(3)Carrying out teaching practice research mainly includes three aspects.First,select the case.Analyze the characteristics of the 7 "scientific inquiry" experiments in the chemistry course 1 of the People's Education Edition.According to the characteristics of the scientific inquiry experiments,the 7 experiments are divided into four categories,and then selects 3 experiments of "scientific inquiry" for case analysis according to the teaching progress and practice time of the school.Clarify the content and type of the three experiments,select appropriate experimental teaching strategies,and develop the teaching design of "literacy texts".Secondly,carry out teaching practice.Two third-level classes in the first grade are selected for the corresponding teaching practice.The experimental class adopts the "literacy text" chemistry experiment teaching design,and the control class adopts the traditional experimental teaching mode.Finally,the results of practical research are obtained.Through the questionnaire,the level of "scientific inquiry and innovation consciousness" of the two class students was tested again,and the improvement of the literacy level before and after the test was compared.It was found that the literacy level of "scientific inquiry and innovative consciousness" of the students in the experimental class improved faster,and theirchemistry scores improved accordingly.(4)Summarized the research and reached the following conclusions: The teaching design of "literacy texts" will not only help improve the students 'level of "scientific inquiry and innovative consciousness",but also improve the comprehensive ability of teachers;create different teaching situations,help to stimulate students' curiosity,focus students' attention;set up different types of chemistry experiments,help to cultivate and develop students' scientific inquiry ability and innovative consciousness.In addition,the idea of carrying out "literacy-based" experimental teaching is also proposed.
