Teachers use four instructional approaches - literature focus units, literature circles, reading and writing workshops, and thematic units - to engage students in authentic language learning. They take on complex, multidimensional roles, differentiating instruction to meet student needs through choices, small groups, centers, integrating all language arts, and incorporating projects. Assessment is also differentiated and authentic, using observations, conferences, checklists and portfolios to evaluate students' development and inform instruction, with the goal of helping all students succeed.
