Typically, Coursera courses do not require students to purchase textbooks. Most course materials are provided online and are included in the course fees. In many cases, instructors curate readings and supplementary materials from various sources that are easily accessible to students directly through the course platform. However, there may be instances where specific courses recommend or suggest additional readings that might be beneficial for deeper understanding, and these could be available as textbooks or articles.
Students can often find relevant resources freely available on the internet or through their local libraries. It is always a good idea to check the syllabus or course description for any particular requirements. For the most current information regarding a specific course's materials, it is best to review the course page directly on the Coursera website. This will provide the most accurate and detailed information regarding any potential resource needs.
