Introduction. We present a study of the academic networks generated by PhD theses on mathematics education read in Spain from 1976 until 2009. Objectives. The main purpose is to identify “invisible colleges” for academic collaboration in Educational Mathematics. Method. Data has been recovered from 328 theses listed in previuos studies, the spanish PhD theses database (TESEO), Spanish Society of Mathematic Education Research (Sociedad Espanola de Investigacion en Educacion Matematica: SEIEM), Mathematics Education departments web pages and direct survey to PhD from mathematics education area. A collaboration networks analysis is performed through bibliometrics techniques. Results. The study both reveals gender bias of thesis advisors and shows there is no correlation between participation in PhD committees and the number of doctoral theses supervised. In this paper we provide updated information on the subject as well as show the changes produced in doctoral theses advising regarding previous works.
