Which action is the MOST appropriate for a teacher when a student is struggling with a new concept?

Making the new material concrete is the most appropriate action for a teacher when a student is struggling with a new concept. This approach involves presenting the information in a tangible way, which can help students understand abstract concepts more clearly. For example, using visual aids, manipulatives, or real-life examples can demystify complex ideas and engage students more effectively. When concepts are represented in a way that students can relate to or physically interact with, it often facilitates better comprehension and retention.

By focusing on concrete representations, a teacher can tailor the learning experience to meet the needs of individual students, thereby providing them with the support they require to grasp challenging material. This approach promotes a growth mindset, encouraging students to engage with their learning process and build their confidence as they understand new concepts.
