Blooms TL classifies learning outcome statements based on Bloom's Taxonomy (Anderson and Krathwhol, 2001). This taxonomy describes the depth of thinking required by students in learning activities and assessments. The six levels in Bloom's taxonomy are: remembering, comprehending, applying, analysing, evaluating, and creating. The classification in this app uses tables containing parts of speech that are generally classified at a given Bloom's level. These tables have been previously been identified in the education literature (Stanny, 2016; von Konsky et al. 2018).
