Core literacy of chemistry discipline

The core literacy of chemistry discipline includes five aspects: macroscopic recognition and microscopic analysis, changing ideas and balanced thinking, evidential reasoning and model cognition, scientific inquiry and innovative consciousness, scientific attitude and social responsibility.

Macro-identification and micro-analysis require us to recognize and classify the diversity of substances from different levels, understand the composition, structure, properties and changes of substances from the levels of elements, atoms and molecules, form the concept that structure determines properties, and analyze and solve practical problems from the perspective of combining macro and micro.

The concept of change and the idea of balance require that substances change in motion, and chemical changes need certain conditions and follow certain laws. The essence of chemical changes is to produce new substances with the transformation of energy. Understanding that chemical changes have certain limits and rates can be regulated. Can analyze chemical changes from multiple angles and dynamically, and solve simple practical problems by using chemical reaction principle.

Evidential reasoning and model cognition need evidence consciousness, which can put forward possible assumptions about the composition, structure and change of substances based on evidence, confirm them through analytical reasoning or establish the guidance of logical relationship between viewpoints and evidence, understand the essential characteristics, components and relationships of research objects through analytical reasoning and other methods to establish cognitive models, and use models to explain chemical phenomena and reveal the essence and laws of phenomena.

Scientific inquiry and innovative consciousness, knowing that scientific inquiry is a scientific practice activity of scientific explanation, discovery, creation and application, can find and put forward problems with inquiry value, can design inquiry schemes according to the assumptions of problems, conduct experimental inquiry by using methods such as chemical experimental investigation, be diligent in practice, be good at cooperation, dare to question and be brave in innovation.

Scientific attitude and social responsibility have a sense of safety, a rigorous and realistic scientific attitude, a sense of exploring the unknown and advocating truth, a deep understanding of the great contribution of chemistry to creating more material wealth and spiritual wealth, meeting people's growing needs for a better life, a sense of sustainable development of saving resources and protecting the environment, forming a simple and moderate green low-carbon lifestyle from themselves, making correct value judgments on chemical-related social hot issues, and participating in chemical-related social practice activities.

Macro-recognition and micro-sigh change ideas, balance ideological evidence, reasoning and model cognition, require students to form chemical thinking methods, scientific exploration and innovative consciousness, encourage students from the practical level, be brave in innovation, and further develop scientific attitude and social responsibility.
