Reflection: Complex Tasks Tests of Water Quality - Section 2: Independent Practice


The background information text I provide in this activity is dense, academic text that includes a variety of scientific and technical vocabulary. Accessing this text is challenging for all students. To help students experience success during this activity, I employ a variety of teaching strategies to help students comprehend what they read. First, I use heterogeneous student groups which contain readers from all levels. I provide time for the students to read together so that strong readers can help their peers. Second, I preteach many of the vocabulary words found in the text in previous lessons so that students have been exposed to the words and their definitions prior to this activity. Lastly, I spend time at each table group so that the students have a human resource upon which they can call if they need support or assistance. Between group work, preteaching, and teacher support, I find that all of my students, even my struggling readers, can be successful in accessing this complex piece of text.
