Visual Thinking Strategies in Montessori Environments

What’s going on in this picture?

Visual Thinking Strategies (VTS) is a powerful, Montessori-aligned practice for fostering critical thinking and deep discussions with children and adults of all ages. Developed in the 1990s at the New York Museum of Modern Art and backed by research, VTS grew into much more than an art appreciation technique. Now used in schools, colleges and universities, science museums, the New York Times, and in many other projects, VTS begins within the simple question, “What’s going on in this picture?” and leads participants in a student-centered, open-ended discussion that emphasizes reflection, evidence, and clear communication skills. Visual Thinking Strategies in Montessori Environments is a detailed, step-by-step guide to the technique created with Montessori in mind. Readers will learn to work guide children from three to eighteen through the facilitated discussions of images and objects—discussions that will enrich children’s thinking and writing across all areas of the curriculum.
