Open educational practices (OEP) have a long history in the field of distance education, but open educational practices as a research field is relatively new. One aspect that has received limited attention is the impact of the use of open educational resources (OER) on the development of open educational practices (OEP). This paper, based on a doctoral study, discusses the experience of teaching with OER and the impact that OER reuse can have on open educational practices in the context of online language teaching. The study examined the activities that teachers engage with when reusing and adapting OER with a view to providing evidence of reuse and understanding whether the activities have an effect on online and open teaching practices. A qualitative study following a constructivist grounded theory methodology was undertaken with 17 parttime online language teachers from the Open University (UK), via individual semistructured online interviews. The paper presents the five-step model of reuse that emerged from the data analysis and discusses the impact of OER reuse on open educational practices. The authors suggest that OER reuse has a positive impact on open educational practices even though the practices might not be 'open' as defined up until now. This study is significant because it focuses on 'open processes' (Knox, 2013) and pedagogical practices with OER. A graphic representation of the findings highlights the process that teachers engage with while using and adapting OER. It brings new understanding about teachers' experiences of reuse showing that the principal motivation for using and adapting OER is to enhance students' learning experience over engaging with digital OEP.
