Out of the debate in Swedish media about homework, the idea for this study was born. The idea was to investigate the popular belief of many foreign language teachers which suggest that homework glossing is a necessity in the English classroom for pupils vocabulary acquisition, while other assumes this method doesn’t lead to knowledge that last. Therefore, the purpose for this study was to examine how learners of English as a foreign language (EFL) manage to learn new words when they received glossing as homework and when they studied the words in a context during class. Furthermore, out of the argument that homework stress pupils and lowers their interest and motivation for the subject, a secondary purpose was to find out pupils’ opinions about learning new words through glossing as English homework. The study was focused on two teaching methods for vocabulary acquisition: the traditional teaching method designed to teach vocabulary by giving glossing as homework, and teaching new words during class with a focus on teaching the new words in context. Through the survey of these two different methods for vocabulary learning and an empirical study with two primary school classes in which these two methods were put on test, contrary to the expectation that learning words through homework glossing wouldn’t lead to vocabulary knowledge that last, the results of the empirical study showed that the group which received glossing as homework, did better on both test than the group which studied the word in context. Similarly, the data results showed the average pupil had a positive attitude to vocabulary homework as for the most part they felt it benefited them to study this method because of the effects of learning.
