Áine Carey discusses Maynooth University Library's adoption of a functional teaching model. The library transitioned to this model to better meet the changing curriculum, information needs of a diverse student population, and develop critical skills. So far, the library has continued classroom instruction while facing challenges with fewer staff and a broader scope. The functional model has strengthened academic engagement and allowed mapping of classes to information literacy standards. Next steps include increased collaboration, workshops, and online resources to provide consistency while accommodating student diversity.
