This TIPS Framework sets out to present ideas to teachers as prospective creators of OER: offering ways they could reflect upon in order to develop a culture of quality within their own respective local communities of practice. We also expect institutions supporting development and use of OER to adopt these Guidelines in their internal quality assurance practices. By offering these Guidelines, we are interested in nurturing the idea of quality as a culture. Developing a culture of quality through teacher continuous professional reflection may be the best way forward rather than simply aiming to digitally store somewhat permanently an individual teacher's own lesson materials. To this end we have added rubrics for Quality Improvement to go alongside OER and these Guidelines.
