Open badges are digital credentials that earners can display anywhere on the web. They are underpinned by an open accreditation infrastructure developed by Mozilla, which enables the issuing of open badges to recognise granular achievements gained through formal and informal learning opportunities and to capture attributes not picked up in formal qualifications, such as the individual qualities that could help a student stand out in the job market. This workshop will focus on effective open badge system development, introducing Mozilla and Jisc toolkits to support badge system design and a strategic approach to implementing open badges in a formal education context. The session will be led by Mozilla and Jisc, and will include tips, case studies and guidance on best practice in badge system design. Participants will gain hands-on experience with tools they can use for developing open badge systems for motivating learning, supporting engagement and progression and enhancing employability.
