Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothes...

In this paper we consider Virtual Learning Systems (VLSs) in which users utilize educational programs. Regarding the role of each system, some infrastructure as software and hardware exist. While several users exist in the VLS, a queue of users is configured. Fault would break down the system and cause learning defects being more serious in virtual learning environment. We consider the queue of...

The present study investigated the effect of the keyword method of vocabulary teaching on the learning and longterm retention of vocabulary in a normal EFL classroom context. Fifty elementary EFL students were selected and assigned into experimental and control groups. The experimental group received vocabulary instruction using mnemonic keyword method and the control group received conventiona...

This study aims to compare the effects of four types of FFI on second language vocabulary learning. To do so, the study adopted a quasi-experimental pretest-posttest design, including five groups, each receiving a distinct treatment. The participants were 80 fourth-grade male students ranging in age from 17 to 19. Before the treatment phase, the participants took a researcher-made test of vocab...

This study investigated the effect of Narrow Reading (NR) on learning mid-frequency words. Vocabulary Size Test (VST) designed by Nation and Beglar (2007) was administered as the first pre-test to 196 students, from among whom 91 students whose vocabulary size ranged between 2100- 3500-word families, , became the target of this study and were randomly c...

Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...

this study investigated the amount of incidental vocabulary learning through comprehension-focused reading of short stories and explicit instruction to this goal.  forty male high school students were selected randomly, and divided into two groups of twenty.  one group of these students was given five 400-word-level short stories to read with the purpose of comprehension, and the students in th...
