A WebQuest is an assignment that asks students to use the internet to learn about and synthesize knowledge on a specific topic. It consists of an introduction, learner objectives, process, resources, evaluation, and conclusion. Key parts include the student's role, intended audience, and task. WebQuests allow students to collaborate and access multimedia resources to complete visual and engaging projects. However, they also risk plagiarism and lack of supervision if used at home. Overall, well-designed WebQuests can provide interactive learning experiences while developing students' research skills when resources are properly evaluated.
