Resumen: Learning to read and write is essential for young pupils, in order to achieve correct communication skills. This dissertation focuses on the method Synthetic Phonics, and more specifically, Jolly Phonics, one of the most popular programmes in the United Kingdom. I will propose an analysis of the historical context and the different phonics approaches to teach literacy in the UK, and how this approach has been introduced in a Spanish school. Then, I will compare the practical development of the method in schools in the UK and in Spain, and how Jolly Phonics teachers value this programme.
