Integration of computer-aided language learning into formal university-level L2 instruction

This paper presents our experience from pilot studies оn integration of intelligent learning and tutoring tools into official curricula for foreign/second-language (L2) learning. We report specifically on initial studies with learners of Russian as a second language at major universities in Italy and in Finland. An important challenge in both of these educational situations is the heterogeneous nature of the student contingent, including the presence of a sizable proportion of ‘heritage’ learners. Furthermore, the groups are often very large, which motivates the integration of an ICALL system. We describe the first integration attempt, an analysis of the emerging aspects and problems, and the design of a new experiment, which is on-going and takes into account the lessons learned. To the best of our knowledge, this is the first report on large-scale ICALL studies involving substantial numbers of ‘high-stakes’ learners of Russian at the intermediate-to-advanced levels – i.e., learners beyond the elementary level.Peer reviewe

AN INVESTIGATION OF EFL LEARNERS ATTITUDES TOWARD COMPUTER-ASSISTED WRITING (CAW)

This dissertation studies attitudes of the Saudi university learners studying English as a Foreign Language (EFL) toward using the Computer-assisted Writing (CAW) applications, e.g., up-to-date versions of word processing programs, for doing English writing assignments. Research has confirmed that CAW applications, e.g., up-to-date versions of word processing program, have been utilized in and out of the class to supplement, but not to replace, the methods of learning and teaching writing. Previous studies have revealed that students attitude towards writing improves when they use the word processor. The current study aims at examining the hypotheses that the EFL learners have effective attitudes towards CAW for writing assignments in EFL, and that they have perspectives about the effects of their attitudes on their writing accuracy and fluency. While the dissertation discusses EFL learners attitude, it also highlights the significance of employing computer technology, e.g., Learning Management Systems (LMSs), Computer-mediated Communications (CMCs) in EFL and in English as a Second Language (ESL) writing instructions. The researcher selected participants pursuing undergraduate English courses in the English Department at three different Saudi university campuses. The sample of the subjects was selected after they were surveyed in the first place for determining their prior knowledge and previous experiences of CAW applications and their ability to write at least a paragraph in English. A 5-point Likert-scale questionnaire, adapted from K. Cunninghams (2002) article, was responded by a total 150 subjects, and open-ended questions were answered by 50 of them to gather and analyze data about their attitudes and their attitude influences on their learning EFL writing. Key findings of the study, concluded after quantitative and qualitative analysis, revealed that the majority of students had positive attitudes toward CAW on their general English writing and on their EFL writing assignments and practice in particular. Key findings of the study included, but are not limited to, the fact that the students positive attitudes lead to raising significant awareness of their writing accuracy (i.e., mainly correcting grammar and spelling errors), writing fluency (i.e., vocabulary selection), and improving their writing ability and revision. The study concluded with several suggestions for future research studies

Investigating language corpora as a grammar development resource

The digital era has brought new concepts and transformations into language development and has given rise to technology-based approaches to learner autonomy. It has shifted the focus from deductive to inductive learning, where the concept of ‘noticing’ (Schmidt, 1990) language forms is promoted. Literature suggests that this type of student-centered self-discovery of lexico-grammatical patterns can be greatly aided by corpus linguistics methods, specifically ‘Data-Driven Learning’ (DDL) (Johns, 1986; Braun, 2005; O’Keeffe et al, 2007). It reports on the valuable potential of DDL for developing learners’ multi-literacies and cognitive strategies, particularly raising their awareness of lexico-grammatical patterning (O’Keeffe and Farr, 2003). However, insights from corpus-based studies have not been widely applied in teaching practices (Reppen, 2022; Zareva, 2017). It has also been proposed that DDL enhances accurate representation of language, raises cultural understanding, provides learners with the freedom to explore and discover the language, and fosters learner autonomy, thus making them more effective language learners (Flowerdew, 2015). This affordance led to the design of a longitudinal experimental study which aimed to provide useful skills and processes in the use of language corpora as a grammar development resource in the pre-intermediate EFL classroom in an Armenain context outside of higher education. The evaluation data included pre-, post-, progress-, delayed post-test data, and Learner Autonomy Profile (LAP) form, the statistical analysis of which revealed the beneficial impact of the computer-based inductive approach of DDL on the learners’ grammar competency, independent learning skills, as well as the contribution of cognitive strategies to proceduralization of knowledge. It also included semi-structured interview data, which uncovered the learners’ increased engagement in the learning process, the positive change in their attitudes towards their own learning, and the ways of demonstrating autonomous abilities in working with concordances. These data also brought to light some of the fears and challenges of using DDL, as well discussing its theoretical and pedagogical underpinnings aligned with psychological processes of learning. The findings will serve all the participants of this hugely important ELT sector - researchers, language educators and learners. They will gain insights as to what is necessary to tap learners’ implicit long-term knowledge, to prepare them both psychologically and practically for independence so that they can be armed with confidence, interest in discovering the language, knowledge about their own learning, and understanding of how to make use of their learning styles and strategies.

Design and evaluation of mobile computer-assisted pronunciation training tools for second language learning

The quality of speech technology (automatic speech recognition, ASR, and textto- speech, TTS) has considerably improved and, consequently, an increasing number of computer-assisted pronunciation (CAPT) tools has included it. However, pronunciation is one area of teaching that has not been developed enough since there is scarce empirical evidence assessing the effectiveness of tools and games that include speech technology in the field of pronunciation training and teaching. This PhD thesis addresses the design and validation of an innovative CAPT system for smart devices for training second language (L2) pronunciation. Particularly, it aims to improve learner’s L2 pronunciation at the segmental level with a specific set of methodological choices, such as learner’s first and second language connection (L1– L2), minimal pairs, a training cycle of exposure–perception–production, individualistic and social approaches, and the inclusion of ASR and TTS technology. The experimental research conducted applying these methodological choices with real users validates the efficiency of the CAPT prototypes developed for the four main experiments of this dissertation. Data is automatically gathered by the CAPT systems to give an immediate specific feedback to users and to analyze all results. The protocols, metrics, algorithms, and methods necessary to statistically analyze and discuss the results are also detailed. The two main L2 tested during the experimental procedure are American English and Spanish. The different CAPT prototypes designed and validated in this thesis, and the methodological choices that they implement, allow to accurately measuring the relative pronunciation improvement of the individuals who trained with them. Both rater’s subjective scores and CAPT’s objective scores show a strong correlation, being useful in the future to be able to assess a large amount of data and reducing human costs. Results also show an intensive practice supported by a significant number of activities carried out. In the case of the controlled experiments, students who worked with the CAPT tool achieved better pronunciation improvement values than their peers in the traditional in-classroom instruction group. In the case of the challenge-based CAPT learning game proposed, the most active players in the competition kept on playing until the end and achieved significant pronunciation improvement results.Departamento de Informática (Arquitectura y Tecnología de Computadores, Ciencias de la Computación e Inteligencia Artificial, Lenguajes y Sistemas Informáticos)Doctorado en Informátic

A Causal-Comparative Study on the Efficacy of Intelligent Tutoring Systems on Middle-Grade Math Achievement

This study is a quantitative examination of intelligent tutoring systems in two similar suburban middle schools (grades 6-8) in the Southeastern United States. More specifically, it is a causal-comparative study purposed with examining the efficacy of intelligent tutoring systems as they relate to math achievement for students at two similar middle schools in the Midlands of South Carolina. The independent variable, use of an intelligent tutoring system in math instruction, is defined as the supplementary use of two intelligent tutoring systems, Pearson’s Math Digits and IXL, for math instruction. The dependent variable is math achievement as determined by the Measures of Academic Progress (MAP) SC 6+Math test. The student data examined is archived MAP SC 6+ Math scores from the 2017-2018 school year. A one-way ANCOVA was used to compare the mean achievement gain scores of both groups, students whose math instruction included intelligent tutoring systems and students whose math instruction did not include intelligent tutoring systems, to establish whether or not there was any statistically significant difference between the adjusted population means of the two independent groups. The results showed that the adjusted mean of posttest scores of students who did not receive math instruction that involved an intelligent tutoring system were significantly higher than those who did

Automatic correction of grammatical errors in non-native English text

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2009.Cataloged from PDF version of thesis.Includes bibliographical references (p. 99-107).Learning a foreign language requires much practice outside of the classroom. Computer-assisted language learning systems can help fill this need, and one desirable capability of such systems is the automatic correction of grammatical errors in texts written by non-native speakers. This dissertation concerns the correction of non-native grammatical errors in English text, and the closely related task of generating test items for language learning, using a combination of statistical and linguistic methods. We show that syntactic analysis enables extraction of more salient features. We address issues concerning robustness in feature extraction from non-native texts; and also design a framework for simultaneous correction of multiple error types. Our proposed methods are applied on some of the most common usage errors, including prepositions, verb forms, and articles. The methods are evaluated on sentences with synthetic and real errors, and in both restricted and open domains. A secondary theme of this dissertation is that of user customization. We perform a detailed analysis on a non-native corpus, illustrating the utility of an error model based on the mother tongue. We study the benefits of adjusting the correction models based on the quality of the input text; and also present novel methods to generate high-quality multiple-choice items that are tailored to the interests of the user.by John Sie Yuen Lee.Ph.D

THE IMPACT OF THE WIKI-ENHANCED TBLT APPROACH ON HIGH SCHOOL STUDENTS’ WRITING SKILL IN A BOYS’ PUBLIC SCHOOL IN AL AIN, UAE

This study investigated the impact of the wiki-enhanced task-based language teaching (TBLT) approach on students’ writing skill in the context of English as a foreign language (EFL) in the United Arab Emirates (UAE). In addition, it explored the students’ and teacher’s views and perceptions toward the implementation of the wiki-enhanced TBLT approach. The study data were collected quantitatively and qualitatively from two classrooms in a public high school in the UAE, which consisted of 30 students. The quantitative data were collected via a pretest–posttest design from the two assigned groups of students: the control and experimental groups. The qualitative data were collected via a survey of the students and a semi-structured interview with the teacher. The study was conducted during a whole academic semester. The findings of the study show that implementing the wiki-enhanced TBLT technique considerably improves EFL learners’ writing skills in relation to the four language components examined in this study: syntactic complexity, grammatical accuracy, fluency, and lexical complexity. In addition, the students enjoyed working together on writing tasks using the wiki-enhanced TBLT approach. Their responses showed that the TBLT approach encourages better performance in collaborative writing tasks and classroom engagement. Moreover, the classroom teachers indicated that the implementation of this approach played a significant role in promoting students’ performance, communication, collaboration, and engagement in the target language (English) in the experimental group. Furthermore, the findings showed that students can construct new knowledge with the aid of their peers, thereby improving their capacity to devise and discuss original ideas. As students can practice collaborative writing while at home, the wiki-enhanced TBLT approach is beneficial for online learning. Adopting this approach increased students’ participation in class because they were more comfortable working together while using technology, improving the quality of their writing and assignments. Several theoretical and pedagogical implications regarding the implementation of this approach have been drawn. The first theoretical implication of this study is that the wiki approach supports previous efforts to move the socio constructivist perspective of learning from the spoken discourse to the written discourse. The second theoretical implication is that it provides support to Chapelle\u27s framework (2003) where learning should be focused on tasks that require the use of the target language. Learning should take place in meaningful and real-life contexts, and instruction should be tailored to the individual needs of the learner. The third theoretical implication is that his study is the first to be conducted in the Gulf region, especially in the UAE. Regarding the pedagogical implications of the TBLT approach, the first pedagogical implication is that teachers need to consider the wiki-enhanced TBLT approach a standard and favored classroom strategy. The second pedagogical implication is that the wiki approach can be used by teachers as a teaching strategy to promote students’ participation and engagement and create a friendly social environment in the L2 classroom. The third pedagogical implication is that technology has proved to be integral in the classroom in teaching and learning the target language. The fourth pedagogical implication is for course designers who need to consider the wiki-enhanced TBLT approach as part of the curriculum. Based on these findings, future research can consider examining the effect of the wiki-enhanced TBLT approach on EFL learners’ writing skill at different levels, such as primary, college, or university students. Future research might also investigate the effect of Google Docs–based TBLT approach on developing students’ writing skill and explore students’ perceptions toward using this approach
