Enhancing Lexical Knowledge through L2 Medium Tasks

Marjan Vosoughi


The purpose of the present study was to investigate the L2 use rate in EFL classrooms through introducing three task conditions in learning lexical items. Date were collected from a group of freshman university students (male and female) studying in Islamic Azad university of Sabzevar, Iran. (N=73). Based on their performance on a Michigan TOEFL reading test battery, they were first randomly divided into three groups, each completing one of the three vocabulary learning tasks that varied in the amount of L1/L2 use they induced during a two month period. The tasks were 'Reading plus further L2 reading', 'Reading plus L1 translation only' and 'dictionary work'. The statistical analysis of the students' performance on vocabulary post-tests was performed through One-Way ANOVA followed with the post hoc Regression Scheffe test to analyze which task has created a meaningful mean variability at 0/05 for both between and within groups. The results showed the outperformance of the group receiving 'reading plus further L2 reading' tasks and not the tasks involving more L1 use. (p:<0.05) Possible implications of the study are presented in the light of Task Load Involvement Hypothesis by (Laufer & Hulstijn, 2001).
