摘要: 普通高中课标提出情景创设和问题设计要有利于发展数学学科核心素养，通过创设合适的数学情境、提出合适的数学问题，促进学生实现知识结构的构建和思维水平的进阶。本文以“一道最佳投资应用题的风波”为例，分析课例中问题情境的真实性，经过分析和思考后提出创设真实性问题情境的针对性教学策略，以期帮助学生提高数学素养和问题解决能力。

Abstract: The curriculum standard of ordinary high school proposes that scenario creation and problem design should be conducive to the development of core literacy of mathematics subject, and promote the construction of knowledge structure and the advancement of thinking level of students by creating appropriate mathematical situations and proposing appropriate mathematical problems. Taking “a storm of the best investment word problem” as an example, this paper analyzes the authenticity of the problem situation in the lesson example, and proposes targeted teaching strategies to create the reality problem situation after analysis and reflection, so as to help students improve their mathematical literacy and problem-solving ability.
