落實素養為本的數學開放題教學

素養為本的數學教學，需要培養學生在不同問題情境中的數學思考、推理、交流、分析和判斷等關鍵能力，以及積極的學習態度。儘管開放題在中國被提出的時間較早，但在課堂教學中重視還不夠，值得進一步探索。開放性的數學問題能夠幫助學生獲得信心和提供學習者多角度思考的機會，不同能力的學生在解答開放題時能夠產生自己的數學思考，形成課堂中的數學交流和討論，培養高層次思維能力。
The competency-based mathematics teaching needed to cultivate students’ key abilities in mathematical thinking, reasoning, communication, analysis and judgment within different problem situations, as well as their positive learning attitudes. Although the open-ended approach had been proposed earlier in China, it was not well emphasized in classroom teaching and was worthy our further exploration. Open-ended mathematics problems could help students gain confidence and provide opportunities for students to think problems from multiple perspectives. Students with different abilities could generate their own mathematical thinking in the process of solving open questions, which formed the mathematical discussions and communications in the classroom and in turn enhanced students’ higher-order-thinking skills.
