Which strategy enhances prior knowledge through field trips and hands-on experiences?

The strategy that enhances prior knowledge through field trips and hands-on experiences is schema activation. This approach involves tapping into the existing knowledge and experiences that a learner already possesses, allowing them to make connections and contextualize new information. Field trips and hands-on experiences can effectively activate a student's schema by providing real-world encounters that relate to what they will be learning. These immersive experiences encourage students to draw on their personal experiences, fostering deeper understanding and retention of new concepts.

In contrast, story walks, cloze exercises, and picture walks are methods that serve different educational purposes. Story walks involve moving through a narrative in a physical space but do not directly reference activating prior knowledge. Cloze exercises focus on reading comprehension and vocabulary by having students fill in missing words in a text, which is less about connecting to prior knowledge. Picture walks involve previewing a book's illustrations to create predictions and engage with the text, but they are more about visual cues than activating broader experiences or knowledge.
