Reflection: Complex Tasks Types of Dams - Section 1: Introduction


In this section of the lesson, I ask students to create a shared definition based on the work of their classmates. This requires students to synthesize information; a skill which is very difficult for fourth graders. To help students create a shared definition, I use a few synthesis strategies. First, I ask students to highlight any words that they see in multiple definitions. I do this by providing a large marker to one student who marks the sentence strips created by the class. I also ask students to look for partial definitions that they could combine. I provide a student with masking tape to physically tape together the sentence strips containing partial definitions. By use multiple senses and physical activity, I try to make the process of synthesizing information from multiple sources a simple one for students.
