According to Anderson & Shattuck (2012, p. 17), what are the characteristics of design-based research?

1. Design-based research is conducted in a real-world context, such as a classroom. 2. It focus on the design and testing of educational interventions, which could be a specific learning activity, type of assessment, administrative innovation (such as starting school later in the morning), or application of some form of technology, among many others. 3. It uses mixed methods, such as combining experimental and qualitative methods. 4. It involves multiple iterations, that is, it repeats the process with the aim of approaching a desired goal. The result of one iteration is used as a starting point for the next one. 5. It involves a partnership between researchers and practitioners. 6. It is intended to contribute to theory.
