This study investigates the effects of collocation task types on Korean high school students' collocation learning and learning attitudes. A total of 118 Korean high school students participated in the experiment, and they were divided into four groups: control group, receptive treatment group, productive treatment group and combination treatment group. In order to investigate the effects of collocation task types on students' English proficiency, each group of students was classified into a high proficiency group and a low proficiency group. The students took a pre-test before the experiment and a post-test after the experiment. After the post-test, the post-questionnaire survey was conducted to examine the students' learning attitudes. The results of the study were as follows: (1) The three types of collocation tasks were effective in learning receptive and productive collocations; (2) in the delayed retention test, it was revealed that the effect of the three types of collocation tasks on both receptive and productive collocation learning lasted; and (3) the result of post-questionnaire survey showed that learning collocation through collocation tasks had positive influence on most students in terms of raising their interest and increasing their self-confidence.

The goal of this paper is to study Korean college students` collocation knowledge of English adjective synonyms. Three pairs of synonymous adjectives big/huge, blank/empty, complete/perfect were selected and tested. The subjects were a total of 50 college students. The results are as follows. First, the average score was as low as 50.67%. Second, there was a somewhat weak positive correlation(r=.475) between college students` general English knowledge and English adjective + noun collocation knowledge. Third, the subjects` scores were not in accordance with the actual use of native English speakers. For example, the score of huge cost was only 28% even though it is a very common expression. Fourth, the subjects` scores were much lower in the case where both adjectives are eligible (higher than 60%) than the case where only one adjective is eligible (lower than 40%). These results suggest that EFL students need to learn English with focus on collocations, not individual words.
