u n i v e r s i d a d a u t ó n o m a d e m a d r i d , s p a i n a b s t r a c tThere has been little research into the conceptions music performance teachers have about learning and instruction, by either psychological or educational researchers. The main aim of this study was to describe the conceptions of 45 Spanish piano teachers from music conservatories, by analysing their differences according to the variable 'Years of teaching experience' (YTE). Three groups of 15 teachers were studied as follows: (1) highly experienced teachers (more than 15 YTE); (2) experienced teachers (between five and 15 YTE); and (3) novice teachers (less than five YTE). Data was collected using written open-ended questionnaires, and analysed by means of the lexicometrical method. Three different conceptions were identified between these groups: direct, interpretative and constructive. The findings suggested that the less experienced the teachers were, the more sophisticated, complex and adapted to music education their conceptions about learning and instruction were. Psychological, educative and curricular implications are discussed. k e y w o r d s : conceptions about learning and instruction, conceptual change, piano teachers, teaching experience Psychology of Music 38 (1)
