Measuring similarity of educational items has several applications in the development of adaptive learning systems, and previous research has already proposed a wide range of similarity measures. In this work, we provide an experimental evaluation of selected similarity measures using a large dataset. The used items are alternate-choice questions…

The article, "morphosyntactic peculiarities of the speech of children with Down's syndrome", treats, important aspects of the study of two adjacent branches of linguistics, namely, psycholinguistics and neurolinguistics-Language development of the child accompanied by speech disorders, on the other hand, those morphosyntactic features…

The present exploratory study investigated the efficacy of secondary face-to-face classroom-based English as a Foreign Language (EFL) instruction digitally supported by the FeedBook, an interactive computer assisted language learning web-based suite of exercises providing item-level scaffolded feedback. Seventy-seven native (L1) German…

Resultative constructions show a wide range of cross-linguistic variation, which may pose nontrivial challenges to L2 learners. This study investigates how syntactic and semantic differences between L1 and L2 affect L2 acquisition of resultatives. In particular, we investigate how L1-Korean learners project the syntax and semantics of L2-English…

This study presents the results of an experiment designed to determine whether knowledge building can facilitate foreign language acquisition. We examined how groups of Catalan students in secondary schools worked together on collaborative writing tasks in English, their foreign language. The students were participating in the Knowledge Building…

This quasi-experimental research aims to investigate the effects of intensive and extensive recasts on learning the English simple present singular -s. In line with this purpose, firstly 56 beginner level learners were non-randomly assigned to three different groups: written intensive recast (n = 20), written extensive recast (n = 17), and control…

Educational systems typically contain a large pool of items (questions, problems). Using data mining techniques we can group these items into knowledge components, detect duplicated items and outliers, and identify missing items. To these ends, it is useful to analyze item similarities, which can be used as input to clustering or visualization…

This paper presents an innovative project-based learning activity meant to support language beginner students to develop, via their core curriculum, five enterprise capabilities ("authentic problem-solving;" "innovation and creativity;" "risk-taking;" "taking action;" and "true collaboration"),…

Voxy, an English-language-learning company, has developed a custom, in-house proficiency exam, the Voxy Proficiency Assessment (VPA), which is given to all learners at the beginning and end of their courses. Using Multinomial Logistic Regression (MLR), the impact of covariates, such as total learning activities completed and total number of…

English plays an important role for the life of the people of East Timor. So it is studied from secondary to tertiary schools. However, the resources of English are not sufficiently available. Under the development concerns the conditions that are faced by both the educator and learners in English as a foreign language course at the university.…

A study is presented that examines the null-subject parameter (NSP) and that seeks to attain the following objectives: (1) to assess the validity of the implicational hierarchy for the NSP, especially as proposed by Liceras (1989); and (2) to determine if there is any evidence to support the theory of the Weaker Logical Problem of Acquisition…

An evaluation of the t-unit as the basic unit of analysis of second language development in written form argues that despite the t-unit's advantages, the sentence-based analysis is superior for examining syntactic complexity in at least three ways: (1) it better characterizes learner knowledge; (2) it facilitates comparison across learners and…

In an effort to learn at which level of language proficiency English for Special Purposes can be taught effectively to nonnative speakers, 50 students at an electronics institute in Algeria were administered eight tests after a 16-week intensive English course. Four of the tests were of skills in English as a second language (ESL): the grammar…

A review of literature on communicative competence reveals many meanings of the concept and of the way it should be used in second and foreign language instruction. In the literature there are two views: that communicative competence includes grammatical competence, and that it does not; or at least the ability to communicate one's meaning is…

An adaptation of an impressionistic scoring method developed for use on student placement in an English as a second language (ESL) program is described and a correlational study of its reliability is presented. The method was chosen because of its efficiency and apparent reliability. The original emphasis of organization, length, and content of…
