MEASUREMENT IN TEACHING RESEARCH: APPLYING RASCH MODEL TO ACCESS LATENT TRACES

ABSTRACT:

We report a discussion about the importance of combining qualitative and quantitative methods to lead specific questions in educational area. We point out the relevance of this approach in order to improve ours methods and obtain greater internal consistency. Rasch model is presented as a tool to access latent traces. We show how this model can be promising to work with measures, as well as answering questions of causality and questions which intend to identify effects and changes.
