“证据推理与模型认知”的化学教学活动

Chemistry Teaching Activities Based on“Evidence Reasoning and Model Cognition”

“证据推理与模型认知”是化学学科核心文化素养之一。在课堂教学过程中,化学教师应不断加强学生的“证据推理与模型认知”的素养培养,帮助学生在知识学习、问题探究、能力训练过程中逐步实现化学知识的掌握、化学探究能力的提升和化学核心素养的完善。本文从分析教材内容、设计学习情境、建立溶解过程和溶解度图像模型入手,探讨了基于“证据推理和模型认知”的化学教学活动。

“Evidence reasoning and model cognition”is one of the core cultural attainments of chemistry.In the process of classroom teaching,chemistry teachers should pay more attention.We should constantly strengthen the cultivation of students'quality of“evidence reasoning and model cognition”to help students in knowledge learning,problem exploration and ability training.In the process of practice,the mastery of chemical knowledge,the improvement of chemical inquiry ability and the improvement of chemical core literacy are gradually realized.This paper discusses the chemistry teaching activities based on“evidence reasoning and model cognition”by analyzing the content of teaching materials,designing the learning situation,and establishing the image model of dissolution process and solubility.
