Online tools and mobile learning can create active learning environments where students engage in discussions, analyze information, pursue investigations, and solve problems. Some benefits of mobile learning include ubiquitous access to content, greater equity of access, increased opportunities for collaboration, and enhanced ability for students to personalize learning. Several online tools are described that help students organize and visualize information. The Visual Ranking Tool allows students to organize lists and compare rankings. The Seeing Reason Tool helps students create visual maps of cause-and-effect relationships to promote collaboration and reasoning. The Showing Evidence Tool provides a framework for students to construct arguments, support claims with evidence, and reach conclusions.
