This edited volume gathers contributions from international scholars focusing on social media's role and impact on mathematics education. Social media's integration into pedagogical strategies (from social networking sites to video-sharing platforms) offers the opportunity to enhance learning by fostering connectivity and engagement among students, ultimately improving mathematical understanding in educational settings. This text aims to provide guidance on the facilitation of peer learning and collaboration, as well as highlighting the necessary shift in traditional methods to include cyber assistance in the learning process. The book discusses how social media aligns with social-constructivist theories of learning, its consistency with the process of developing students into independent learners and provides means to ensuring educators remain relevant and connected to students' preferred modes of learning. Challenges and benefits of the use of social media tools in teaching are also detailed. Examining the potential for effective integration of social media in the classroom, this book is a valuable resource for educators, practitioners and researchers interested in mathematics education.
