【摘要】 立足于化学科学思维的培养，以真实情境为导引，借助溶液酸碱性和酸碱度的科学探究实验，将核心知识与探究活动紧密结合起来。通过对实验事实进行证据推理，以及比较、分析、综合、归纳等，建构pH与溶液酸碱度的关系模型，以培养学生的解决化学相关真实问题的科学思维等化学学科核心素养，并感受化学学科的应用价值。更多还原

【Abstract】 Oriented by the training and development of scientific thinking, this paper designs the teaching process of exploring the pH of solution. Taking the real situation as carrier, the core knowledge and the learning activity are closely combined. Through the students’ evidence reasoning on experimental facts and the application of scientific methods such as comparison, analysis, synthesis, and induction, a model for the relationship between pH and acidity-alkalinity of the solution is established, which cultivates students’ core literacy of chemistry, such as scientific thinking for solving real problems related to chemistry, and enables them to feel the application value of chemistry.更多还原
