Teaching in health residencies: knowledge of preceptors under Shulman's analysis.

Objectives: to understand how the pedagogical knowledge that integrates the basic knowledge of teaching is perceived by preceptors in residents' teaching-learning process.
Methods: a qualitative research conducted by semi-structured interview from December 2013 to July 2014, with 31 preceptors of residency programs of three university hospitals in northeastern Brazil. For analysis, the Grounded Theory's proposal was used and supported by Atlas ti(r) 7.0 software.
Results: preceptors integrate preceptorship with basic teaching knowledge proposed by Lee Shulman, with emphasis on General Pedagogical Knowledge when seeking strategies to better work on specific and disciplinary content, and Pedagogical Content Knowledge when adapting content to make it comprehensible to residents.
Final Considerations: the study allowed us to understand how Shulman's basic knowledge of teaching is perceived by preceptors. It is recognized that they integrate knowledge into the preceptorship, highlighting the General and Pedagogical Content Knowledge.
