Traditional and modern vocabulary instruction techniques have been introduced in the past few decades to improve the learners’ performance in reading comprehension. Semantic mapping, which entails drawing learners’ attention to the interrelationships among lexical items through graphic organizers, is claimed to enhance vocabulary learning significantly. However, whether this technique suits all...

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...

the present study is an attempt to contribute to the l2 acquisition research through finding an appropriate answer to the question usually asked by both language teachers and learners, namely how to learn vocabulary and how to retain meanings in memory over time. we have chosen to discover the effects of two major types of productive exercises, writing and oral production exercises, on the reme...

This study aimed at investigating the impact of closed-caption program on listening comprehension of English movies and vocabulary learning. Sixty-four graduate students studying at Shiraz Islamic Azad University were selected as the participants of the study. The participants were divided into two groups: experimental group (with closed caption program) and control group (without closed captio...

In our modern technological world, Computer-Assisted Language learning (CALL) is a new realm towards learning a language in general, and learning L2 vocabulary in particular. It is assumed that the use of multimedia annotations promotes language learners’ vocabulary acquisition. Therefore, this study set out to investigate the effects of different multimedia annotations (still picture annotatio...

Model expansion problem is a question of determining, given a formula and a structure for a part of the vocabulary of the formula, whether there is an expansion of this structure that satisfies the formula. Recent development of a problem-solving paradigm based on model expansion by (Mitchell & Ternovska, 2005; Mitchell, Ternovska, Hach, & Mohebali, 2006) posed the question of complexity of thi...

In this paper, we show how to accomodate a Bayesian variant of Rissanen’s MDL into on-line Bayesian adaptation to control both model structural complexity and parameterization complexity to best fit an available amount of adaptation data, the goal being minimization of resulting recognition error. An efficient bottom-up dynamic programming based pruning algorithm is developed for selecting mode...

Most of the studies on the key word method of second/foreign language vocabulary learning have been based on the evidence from laboratory experiments and have primarily involved the use of English key words to learn the vocabularies of other languages. Furthermore, comparatively quite limited number of such studies is done in authentic classroom contexts. The present study inquired into the eff...

This study aimed to investigate the effects of concept mapping on the extent to which Iranian EFL learners retain new vocabularies and the degree of awareness toward vocabulary learning strategies they tended to use. To this end, a total of 40 Iranian EFL students were asked to participate in this study. They were randomly assigned to two equal groups; namely, experimental and control. The part...

Collaborative tagging allows users to assign arbitrary keywords (or tags) describing the content of objects, which facilitates navigation and improves searching without dependence on pre-configured categories. In large-scale tagbased systems, tag recommendation services can assist a user in the assignment of tags to objects and help consolidate the vocabulary of tags across users. A promising a...
