Editorial commentary

Open materials is one of three pillars of the Open Practices Badges (alongside open data and pre-registration). What constitutes 'materials' depends on field: in psychology, the stimuli and instruction text; in education, lesson plans; in chemistry, synthesis procedures and reagent provenance.
