Which learning theory does the 4th-grade teacher demonstrate by having students find and compare the areas of rectangles?

The correct answer is Constructivist. This learning theory emphasizes the importance of students actively engaging in the learning process through exploration and personal discovery. By having students find and compare the areas of rectangles, the teacher is encouraging them to construct their understanding of mathematical concepts. This hands-on approach allows students to apply their knowledge in a meaningful context, leading to deeper understanding and retention of the material.

In a constructivist framework, the learning experience is not solely about receiving information from the teacher; instead, it involves students working through problems, collaborating with peers, and developing their own solutions. The activity of measuring and comparing areas requires critical thinking and problem-solving skills, which are central to constructivist teaching practices. This fosters an environment where students can build upon their existing knowledge and relate new concepts to their prior experiences.

Behaviorism, on the other hand, focuses on observable behaviors and emphasizes direct instruction and reinforcement. Humanism centers on the development of the whole person, prioritizing emotional well-being and self-directed learning. Cognitivism looks at the mental processes involved in learning, but it does not necessarily emphasize the hands-on, exploratory aspect present in the described activity. Therefore, the constructivist approach aligns closely with the methodology employed by the teacher in this
