Use of CALL for the four skills

A number of studies have been done concerning how the use of CALL affects the development of language learners’ four skills (listening, speaking, reading and writing). Most report significant gains in reading and listening and most CALL programs are geared toward these receptive skills because of the current state of computer technology. However, most reading and listening software is based on drills. [5] Gains in writing skills have not been as impressive as computers cannot assess this well. [6]

However, using current CALL technology, even with it current limitations, for the development of speaking abilities has gained much attention. There has been some success in using CALL, in particular computer-mediated communication, to help speaking skills closely linked to “communicative competence” (ability to engage in meaningful conversation in the target language) and provide controlled interactive speaking practice outside the classroom. [3] Using chat has been shown to help students routinize certain often-used expressions to promote the development of automatic structure that help develop speaking skills. This is true even if the chat is purely textual. The use of videoconferencing give not only immediacy when communicating with a real person but also visual cues, such as facial expressions, making such communication more authentic. [6]

However, when it comes to using the computer not as a medium of communication (with other people) but as something to interact with verbally in a direct manner, the current computer technology’s limitations are their clearest. Right now, there are two fairly successful applications of automatic speech recognition (ASR) (or speech processing technology) where the computer “understands” the spoken words of the learner. The first is pronunciation training. Learners read sentences on the screen and the computer gives feedback as to the accuracy of the utterance, usually in the form of visual sound waves. [3] The second is software where the learner speaks commands for the computer to do. However, speakers in these programs are limited to predetermined texts so that the computer will “understand” them. [5]

[edit] Multimedia language centers

During the 1960s, language laboratories with cassette players and headphones were introduced into educational institutions. The use of this kind of center grew rapidly in the late 1960s and 1970s, but then went rapidly out of fashion."[9] Later, “digital language labs” were introduced, still following the traditional language format, such as teacher monitoring. What made them new what that they incorporated new technologies such as video. The term multimedia was originally used to describe sets of learning materials which included a book, audiocassettes and/or videocassettes. However, with the advent of computer-based materials, such packages tend to be called multiple media or mixed media - although there is not absolute consensus on this point. Nowadays multimedia refers to computer-based materials that can perform more varied tasks then the purely-audio mixed-media. Not only can such play pre-recorded audio and video material, it can create new audio and video recordings. It also has the capability of integrating the four basic skills of listening, speaking, reading and writing, as well as giving immediate, if limited, feedback to the student. However, like its predecessors, multimedia centers run the risk of being underutilized due to poor management. [10]

While multimedia computer-based materials can be used directly in the classroom, because of costs, such resources are usually found in a multimedia language center, fulfilling the role of the previous cassette-based and digital language laboratories. However, managing such a center requires knowledge of a wide range of equipment and the increasing expectations of such equipment from administrators, language teachers and students. Administrators often have the mistaken belief that buying hardware by itself will meet the needs of the center (often devoting 90% of a center’s budget to such and ignoring software and training needs) and will cut down on the number of teaching staff needed. [11]

While multimedia offers many opportunities for language learning with the availability of text, images, sound and video as well as interactive activities, the problem is that these opportunities have not been taken advantage of well. Most multimedia computer programs tend to be strong on presentation but weak as far as pedagogy and even interaction. One of the main promises of CALL is the ability to individualize learning, but like with past language laboratories, use of the facilities in many cases have devolved into rows of students all doing the same drills. The only advantage to the multimedia in these cases has been better sound and color images. Most modern language learning theories stress the importance of teacher guidance rather than control, giving students control over what they do, how fast they do it and even the ability to find and correct their own mistakes.[11]

Managing a multimedia language center properly requires not only knowledge of foreign languages and language teaching methodology, it also requires a certain amount of technical know-how and budget management ability as well as the ability to combine all these into creative ways of taking advantage of what the technology can offer. Often a center manager needs assistants for technical problems, for managing resources and even the tutoring of students. Multimedia centers lend themselves to self-study, and potentially self-directed learning, but such is often misunderstood. The simple existence of computers in a laboratory does not automatically lead to students learning independently. Significant investment of time is essential for materials development and creating an atmosphere conducive to such.

Self access language learning centers or independent learning centres have emerged partially independently, and partially in response to these issues. In self-access learning, the focus is on developing learner autonomy through varying degrees of self-directed learning, as opposed to (or as a complement to) classroom learning. In most centres, learners access materials and manage their learning independently, but have access to staff for help. Many self-access centres are heavy users of technology and an increasing number of them are now offering online self-access learning opportunities. Some centres have developed novel ways of supporting language learning outside the context of the language classroom (also called 'language support') by developing software to monitor students' self-directed learning and by offering online support from teachers (cf. [12])

Center managers and support staff need to have new roles defined for them to support students’ efforts at self-directed learning. In fact, a new job description has emerged recently, that of a “language advisor”[13].

[edit] Advantages of CALL

[edit] Motivation

Generally speaking, the use of technology inside or outside the classroom tends to make the class more interesting. However, certain design issues affect just how interesting the particular tool creates motivation. [6] One way a program or activity can promote motivation in students is by personalizing information, for example by integrating the student’s name or familiar contexts as part of the program or task. Others include having animate objects on the screen, providing practice activities that incorporate challenges and curiosity and providing a context (real-world or fantasy) that is not directly language-oriented.

For example, a study comparing students who used “CornerStone” (a language arts development program) showed a significant increase in learning (compared to students not using the program) between two classes of English-immersion middle-school students in language arts. This is because CornerStone incorporate personalized information and challenging and imaginative exercises in a fantasy context. [14] Also, using a variety of multimedia components in one program or course has been shown to increase student interest and motivation. [6]

One quantifiable benefit to increased motivation is that students tend to spend more time on tasks when on the computer. More time is frequently cited as a factor in achievement. [6]

[edit] Adapting learning to the student

Computers can give a new role to teaching materials. Without computers, students cannot really influence the linear progression of the class content but computers can adapt to the student. [5] Adapting to the student usually means that the student controls the pace of the learning but also means that students can make choices in what and how to learn, skipping unnecessary items or doing remedial work on difficult concepts. Such control makes students feel more competent in their learning. [14] Students tend to prefer exercises where they have control over content, such as branching stories, adventures, puzzles or logic problems. With these, the computer has the role of providing attractive context for the use of language rather than directly providing the language the student needs. [5]

[edit] Authenticity

“Authenticity” in language learning means the opportunity to interact in one or more of the four skills (reading, writing, listening, speaking) by using or producing texts meant for an audience in the target language, not the classroom. With real communication acts, rather than teacher-contrived ones, students feel empowered and less afraid to contact others. Students believe they learn faster and better with computer-mediated communication. [5] Also, students learn more about culture in such an environment. [6] In networked computer environments, students have a conscious feeling of being members of a real community. In situations where all are learners of a foreign language, there is also a feeling of equality. In these situations students feel less stressed and more confident in a language learning situation, in part because surface errors do not matter so much. This works best with synchronous CMC (e.g. chats) as there is immediate feedback but email exchanges have been shown to provide most of the same benefits in motivation and student affect. [5]

[edit] Critical thinking skills

Use of computer technology in classrooms is generally reported to improve self-concept and mastery of basic skills, more student-centered learning and engagement in the learning process, more active processing resulting in higher-order thinking skills and better recall, gain confidence in directing their own learning. This is true for both language and non-language classrooms. [6]

[edit] Problems and criticisms of CALL instruction

The impact of CALL in foreign language education has been modest. [3] Several reasons can be attributed to this.
The first is the limitations of the technology, both in its ability and availability. First of all, there is the problem with cost[1] and the simple availability of technological resources such as the Internet (either non-existent as can be the case in many developing countries or lack of bandwidth, as can be the case just about anywhere). [5] However, the limitations that current computer technology has can be problematic as well. While computer technology has improved greatly in the last three decades, demands placed on CALL have grown even more so. One major goal is to have computers with which students can have true, human-like interaction, esp. for speaking practice; however, the technology is far from that point. Not to mention that if the computer cannot evaluate a learner’s speech exactly, it is almost no use at all. [3][1]
However, most of the problems that appear in the literature on CALL have more to do with teacher expectations and apprehensions about what computers can do for the language learner and teacher. Teachers and administrators tend to either think computers are worthless or even harmful, or can do far more than they are really capable of. [8]
Reluctance on part of teachers can come from lack of understanding and even fear of technology. Often CALL is not implemented unless it is required even if training is offered to teachers. [8] One reason for this is that from the 1960’s to the 1980’s, computer technology was limited mostly for the sciences, creating a real and psychological distance for language teaching. [15] Language teachers can be more comfortable with textbooks because it is what they are used do, and there is the idea that the use of computers threatens traditional literacy skills since such are heavily tied to books. [15] [16] These stem in part because there is a significant generation gap between teachers (many of whom did not grow up with computers) and students (who did grow up with them).
Also, teachers may resist because CALL activities can be more difficult to evaluate than more traditional exercises. For example, most Mexican teachers feel strongly that a completed fill-in textbook “proves” learning. [16] While students seem may be motivated by exercises like branching stories, adventures, puzzles or logic, these activities provide little in the way of systematic evaluation of progress. [5]
Even teachers who may otherwise see benefits to CALL may be put off by the time and effort needed to implement it well. However “seductive” the power of computing systems may be[5], like with the introduction of the audio language lab in the 1960’s, those who simply expect results by purchasing expensive equipment are likely to be disappointed. [1] To begin with, there are the simple matters of sorting through the numerous resources that exist and getting students ready to use computer resources. With Internet sites alone, it can be very difficult to know where to begin, and if students are unfamiliar with the resource to be used, the teacher must take time to teach it. [5] Also, there is a lack of unified theoretical framework for designing and evaluating CALL systems as well as absence of conclusive empirical evidence for the pedagogical benefits of computers in language. [3] Most teachers lack the time or training to create CALL-based assignments, leading to reliance on commercially-published sources, whether such are pedagogically sound or not. [1]
However, the most crucial factor that can lead to the failure of CALL, or the use of any technology in language education is not the failure of the technology, but rather the failure to invest adequately in teacher and the lack of imagination to take advantage of the technology's flexibility. Graham Davies states that too often, technology is seen as a panacea, especially by administrators, and the human component necessary to make it beneficial is ignored. Under these circumstances, he argues, "it is probably better to dispense with technology altogether".[9]

Rody Klein, Clint Rogers and Zhang Yong (2006) studying the adoption of Learning Technologies in Chinese schools and colleges have also pointed out that the spread of video games on electronic devices, including computers, dictionaries and mobile phones, is feared in most Chinese institutions. And yet every classroom is very well equipped with a desk imbedded computer, Internetconnexion, microphone, video projector and remote controlled screen to be used by the teacher for multimedia presentations. Very often the leaders prefer to ban completely Learning Technologies for students at the dismay of many foreign ESL teachers. Books and exercise books still prevail. In order to enhance CALL for teaching ESL and other languages in developing countries, it would be also crucial to teach students how to learn by themselves and develop the capacity to practice self evaluation and enhance intrinsic motivation. Tests and quizzes should be designed accordingly to encourage and enhance students autonomous practice. Teachers using CALL should be computer literate and trained continously. Ideally each Foreign Language Department using CALL should hire an experienced Computer Scientist who could assist teachers. That expert should demonstrate dual expertise both in Education and Learning Technologies.
