Although measures of lexical complexity are well established for printed texts, there is currently no equivalent work for videos. This study, therefore, aims to investigate whether existing lexical complexity measures can be extended to predict second language (L2) learners' judgment of video difficulty. Using a corpus of 320 instructional videos,…

This study examines the role of recast frequency and its effectiveness in the acquisition of English articles in a computer-mediated context. Sixty-one preintermediate university language learners in Turkey were randomly divided into four main groups: high frequency recast (HF), low frequency recast (LF), test control, and task control groups. The…

The measurement of knowledge contribution in collaborative knowledge building is an important research topic in computer-supported collaborative learning. The information measures of knowledge contribution based on information theory are proposed in this study, which includes two measures: amount of information and information gain. Discourse data…

This study investigates the use of L1 glosses during computerized reading in the English Language Teaching (ELT) context. A group of 26 ELT students at a large Turkish public university read three short texts and used pop-up glosses to promote their comprehension. Web pages were designed for reading and glosses, and a screen capture tool recorded…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

We investigated the efficiency of briefly presenting word forms (visual dictation) over and above word copying in 5 computerized repeated spelling training sessions of Dutch rule-based and loan words in advanced spellers in primary school. Using repeated measures analyses of variance, we compared the effects of 2 spelling feedback conditions in a…

This study investigates the extent to which microfeatures -- such as basic text features, readability, cohesion, and lexical diversity based on specific word lists -- affect Chinese EFL writing quality. Data analysis was conducted using natural language processing, correlation analysis and stepwise multiple regression analysis on a corpus of 268…

This paper reports on task interaction, task success and word learning among second language (L2) learners of different levels of word recognition from speech (WRS) proficiency who used a CALL application previously shown to be effective in the development of L2 WRS. Participants (N = 65) were categorised into three levels of L2 WRS proficiency…

When it comes to language learning, vocabulary learning is the main activity focused on. Vocabulary learning is the main problem and also the goal of new language learners. It is one of the major problems that language learners encounter during learning a new language. Krashen (1989) (cited in Tokac, 2005) points out the role of vocabulary in a…

The value and role of concordancers (simple computer programs that can quickly analyze electronic texts to find occurrences of a given word, part of a word, or phrase and display it within its immediate context) in secondary school English-as-a-Second-Language (ESL) teaching are examined. First, their use in higher education is discussed,…
