The document discusses using the BIG6 model to help students develop critical thinking skills related to information literacy. The BIG6 model involves 6 stages: 1) task definition, 2) information seeking strategies, 3) location and access, 4) use of information, 5) synthesis, and 6) evaluation. For each stage, the document provides guidance on activities and questions to help students develop skills such as determining information needs, finding and evaluating appropriate sources, extracting and organizing relevant information, and assessing both the problem-solving process and final product or learning outcomes. The overall goal is to prepare students for lifelong learning and contribution to various communities.
