[eng] Vocabulary development is thought to be one of the most essential aspects when
learning a language. However, the current Spanish educational system seems to
be more focused on the teaching of grammar than on the teaching of vocabulary.
This is clearly reflected in the students’ language performance, which is proved
to be one of the poorest across Europe. A possible measure aimed at helping
EFL students increase their vocabulary would be the teaching of Greco-Latin
prefixes and suffixes. Taking into account that in the Balearic Islands Spanish
and Catalan are spoken, it is imperative to analyse the benefits that teaching this
grammar strategy in these two languages would have for EFL learners. This
paper reveals the lack of coordination that exists in the three language curricula
of the Obligatory Secondary Education, which is mirrored in the lack of
coordination among the departments of the IES Son Ferrer, a high school on the
island of Mallorca in Spain. Teaching Greco-Latin prefixes and suffixes may draw
a lukewarm response from students. For this reason, the best approach to the
teaching of this grammar strategy is to introduce educational games in the
classroom. The main aim of this paper, therefore, is to present a didactic proposal
aimed at teaching Greco-Latin affixes to EFL students through educational
games in order to increase their motivation and help them expand their
vocabulary in a dynamic way.
