Critical thinking aims to get students to analyze problems and construct their own answers rather than relying on textbooks. It is important because it helps students learn better by looking more deeply for answers and thinking critically about solutions rather than being given answers explicitly. In the 21st century, technology like blogs, webquests, and social media can be used to promote critical thinking by engaging students in interactive activities that require analysis and creative problem solving. For example, students can be split into groups to brainstorm and prioritize issues in a story using an online tool called GroupMap that allows collaborative mind mapping.
