A Language-Independent Approach to Automatic Text Difficulty Assessment for Second-Language Learners
نویسندگان
چکیده
In this paper, we introduce a new baseline for language-independent text difficulty assessment applied to the Interagency Language Roundtable (ILR) proficiency scale. We demonstrate that reading level assessment is a discriminative problem that is best-suited for regression. Our baseline uses z-normalized shallow length features and TF-LOG weighted vectors on bag-of-words for Arabic, Dari, English, and Pashto. We compare Support Vector Machines and the Margin-Infused Relaxed Algorithm measured by mean squared error. We provide an analysis of which features are most predictive of a given level.

The current pretest-posttest quasi-experimental study attempts, firstly, to probe the effects of teaching formulaic sequences (FSs) on the second or foreign language (L2) learners' oral proficiency improvement and secondly, to examine whether teaching FSs through different resources (i.e. animation vs. text-based readings) have any differentially influential effects in augmenting L2 l...

In the present study, an exploratory approach (Oxford, Cho, Leung & Kim, 2004) to language learning is adopted which holds that the number and type of strategies used by Iranian learners might vary with respect to the difficulty of task and their L2 proficiency. In this regard, the term task is defined, its leading dimentions and charecteristics are put forward, and the nature of learning start...

After moving away from the psychometric and the integrative language testing paradigms toward the communicative language testing paradigm, experts in writing and assessment have been concerned with creating conditions under which learners can experience and display writing in an authentic way so that their writings will tally the ones in non-test situations. As an alternative assessment option,...
