Abstract:In this study, the ADAPT-instrument was further developed in three phases with, as a result, recommendations for further development. ADAPT stands for ‘Assessing Differentiation in All Phases of Teaching’ and entails an analysis of teacher documents, lesson observation and an interview tailored to the observed lesson. In the first phase, the instrument was adjusted for scoring guidelines during a focus group of experts, followed by a training of raters. In the second phase, it was examined whether there was an inter-rater agreement. In addition, rater’s comments were analysed together with some descriptive statistics. In the third phase the ADAPT-instrument was adjusted, during an expert meeting, based on the results of phase 2 and an improved version was developed. Then, this improved version was analysed based on the evaluation framework of Dobbelaer (2019) which can be used to evaluate the quality of the instrument and to evaluate the evidence gathered for reliability and validity of the instrument. Overall, the ADAPT-instrument has made major quality steps towards reliability and validity criteria and, after further development, is expected to be able to assess the complex professional competency DI in all phases of teaching.
