Application Of The Core Literacy "Question List" In Breaking Through Chemistry Teaching Difficulties

With the deepening of the concept of new curriculum reform,the core literacy system has become the trend of contemporary international education development.Core literacy of chemistry is an important part of the core literacy.The difficulty of chemistry teaching is often the point of differentiation of students' learning,which be regarded as the obstacle of students' learning.The breakthrough of chemistry teaching plays a very important role in the transforming of the mode of students' learning,cultivating students' will,emotion,anti-setbacks and other quality,even innovative thinking and developing students' core chemistry.How to break through the difficulties and seek the opportunity to cultivate students' core accomplishment has become an important subject of front-line teachers' research.The new curriculum reform advocates inquiry learning,while the problem teaching method is the popular teaching method which fits the idea.For the middle school teachers,many of them adopt the problem string to guide the students to think,solve and realize the problem effectively.Chemistry as an important part of secondary school discipline,teaching students to help break through the difficult problem is one of teaching tasks.The optimized scheme of analysis chemistry teaching difficult has important practical significance to enhance the quality of teaching chemistry.Therefore,this topic attempts to solve the problem of how to improve the students' core literacy by setting the breakthrough teaching difficulty to cultivate the core accomplishment of the students,and based on the teaching practice of chemical problems string design research.This study based on the summary of the others and mainly did the following research:(1)Sorted the literatures of different definition,types and applied researches of "problem strings" by literature research method,then proposed the thought of applying problem strings to chemistry teaching difficulty.(2)Take the Chemistry compulsory teaching materials 1&2 for example,sort the difficult teaching points,then achieve the goal of core literacy of chemistry—“Identification of macro and micro analysis”,"The ideas of changes and balance","evidence reasoning and model recognition","experimental exploration and innovation","scientific attitude and social responsibility".(3)Based on the Constructivism Learning Theory and Constructivist Learning Theory,this study tried to apply the “problem string” to the four chemical teaching points,designed the principle and proposed requirements in teaching.At last,we launched practice research in a middle school in Zhangzhou,then analyzed the teaching effect through classroom observation.The research showed that adopting “problem string” in teaching had some advantages.Firstly,it help students to cultivate the ability of asking questions,analyzing and solving problems;Secondly,cultivate the students' creative thinking;Thirdly,break through the difficulties of chemistry teaching;Lastly,cultivate the students' chemistry core literacy.
