Which technique is effective for teaching mathematical problem-solving?

Using real-life scenarios is an effective technique for teaching mathematical problem-solving because it helps students relate mathematical concepts to everyday situations. This contextual approach engages students and enhances their understanding of how mathematics applies to the world around them. When students can see the relevance of what they're learning, they are more likely to be motivated and interested in the material. Real-life scenarios encourage students to think critically and creatively as they apply mathematical concepts to solve problems, promoting deeper learning and retention of information.

In contrast, while standardized tests can assess mathematical knowledge, they do not necessarily foster problem-solving skills in a practical context. Rote memorization focuses on memorizing formulas or procedures without understanding their application, which can lead to difficulties in transferring knowledge to new situations. Additionally, an emphasis on theoretical concepts might not provide the practical skills needed for problem-solving in real-life contexts. Therefore, utilizing real-life scenarios stands out as a method that cultivates both interest and practical problem-solving abilities in mathematics.
