Computer-Aided Language Learning: An Overview

Computer-Aided Language Learning (CALL) represents a dynamic and evolving field dedicated to exploring the use of computer applications in language teaching and learning. CALL encompasses a wide array of information and communications technology applications and approaches to teaching and learning foreign languages. While CALL goes by other names, it seems to be the most widely accepted generic term.

Defining CALL

CALL, an abbreviation for Computer Assisted Language Learning, is an interactive method of instruction that helps learners achieve their goals of learning, at their own pace and ability. According to Levy (1997), CALL is "the exploration and study of computer applications in language teaching and learning."

Historical Context

The term CALI (computer-assisted language instruction) was used before CALL, originating as a subset of the broader term CAI (computer-assisted instruction). CALI fell out of favor among language teachers, however, because it seemed to emphasize a teacher-centered instructional approach. Language teachers increasingly favored a student-centered approach focused on learning rather than instruction. CALL began to replace CALI in the early 1980s.

Alternative Terminology

An alternative term, technology-enhanced language learning (TELL), also emerged around the early 1990s.

The Evolution of CALL

CALL has evolved significantly since its inception, transitioning from traditional drill-and-practice programs to more sophisticated applications that leverage virtual learning environments and Web-based distance learning.

Three Phases of CALL

Warschauer (1996) and Warschauer & Healey (1998) described three phases of CALL:

Behavioristic CALL (1960s to 1970s): This phase primarily consisted of drill-and-practice materials where the computer presented a stimulus and the learner provided a response. The computer analyzed the student's input and provided feedback, with more advanced programs offering help screens and remedial activities.
Communicative CALL: Based on the communicative approach, this phase focused on using the language rather than analyzing it, with grammar taught implicitly. It coincided with the rise of the PC, leading to a surge in language learning software development. Computers provided context for language use, and programs like Sim City and Where in the World is Carmen Sandiego? were utilized for language learning.
Integrative CALL: Starting in the 1990s, this phase integrated language skills teaching into tasks or projects, aligning with the development of multimedia technology and computer-mediated communication (CMC). The focus shifted from the computer as a tutor to a medium for extending education beyond the classroom.

Bax argued that at the time of writing language teachers were still in the Open CALL phase, as true integration could only be said to have been achieved when CALL had reached a state of "normalisation" - e.g.

Core Principles of CALL

The current philosophy of CALL emphasizes student-centered materials that empower learners to work independently. These materials typically incorporate interactive and individualized learning, assisting teachers in facilitating language learning. The design of CALL materials integrates principles from language pedagogy and methodology, drawing from various learning theories such as behaviorism, cognitive theory, constructivism, and second-language acquisition theories.

Blended Learning

A combination of face-to-face teaching and CALL is usually referred to as blended learning.

The Benefits of CALL

CALL offers numerous benefits for both learners and teachers, enhancing language acquisition through interactive and engaging methods.

Advantages for Learners

Personalized Learning: CALL allows learners to progress at their own pace and ability, catering to individual learning styles and needs.
Increased Engagement: Interactive exercises, multimedia resources, and game-based learning enhance learner motivation and engagement.
Access to Authentic Materials: CALL provides access to a vast array of digital text, audio, and video materials, exposing learners to real-world language use.
Development of Digital Literacy: Integrating technology into language learning helps learners develop essential digital skills.
Interactive Discussions: CALL facilitates interactive discussions and collaboration with peers, fostering a communicative learning environment.
Culture Immersion: Exposure into the target language cultures.

Advantages for Teachers

Enhanced Teaching Tools: CALL provides tools that assist teachers in facilitating language learning, whether reinforcing classroom lessons or providing additional support to learners.
Time Efficiency: CALL can automate certain tasks, freeing up teachers' time for more personalized instruction and feedback.
Access to Resources: Teachers can access a wide range of digital resources and tools to create engaging and effective learning experiences.
Improved Assessment: CALL offers opportunities for detailed assessment of learner skills and performance.

Key Components of an Intelligent Tutoring System (ITS) for Language Learning

Intelligent Tutoring Systems (ITS) are a key component of CALL, designed to provide personalized and adaptive language learning experiences. An ITS typically comprises three core components:

Domain Model: Represents the knowledge structure of the language, including linguistic rules, vocabulary, and grammar. The Domain model typically encompasses various types of knowledge, such as declarative and procedural knowledge. It is a representation of everything that must be mastered by the learner: facts, rules, concepts, etc., (known as skills in ITS literature)-and the relationships among them. For language learning, the Domain model includes linguistic phenomena or rules ranging in specificity.
Student Model: Represents the learner's current knowledge and skill level, including static characteristics (e.g., mother tongue) and dynamic characteristics (e.g., performance on tasks).
Instruction Model (or Tutor Model): Determines what to teach, when to teach it, and how to teach it, based on information from the Student and Domain models.

ITS Functions

ITS functions that are considered to be important for the success of CALL include: (1) generation of exercises that target both productive and receptive skills across varying proficiency levels; (2) detailed assessment of the learner’s skills/performance, the learning material’s difficulty, and individual learning items; (3) provision of feedback that the ITS communicates to the learner throughout the learning process; (4) and the analytics that inform the learner and teacher during the learning process, potentially outlining a learning pathway toward the desired proficiency levels.

Types of CALL Activities

CALL encompasses a wide range of activities and applications, including:

Vocabulary Acquisition: Using flashcards and spaced repetition techniques to enhance vocabulary retention.
Grammar Exercises: Engaging in gap-filling, multiple-choice, and sentence-reordering exercises to reinforce grammar concepts.
Reading Comprehension: Answering factual questions and determining the truth value of statements based on texts.
Listening Comprehension: Completing tasks based on audio and video materials.
Speaking Practice: Participating in virtual exchanges and language learning in virtual worlds.
Game-Based Learning: Utilizing video games and simulations to create immersive and interactive learning experiences.
Mobile-Assisted Language Learning (MALL): Using mobile devices and apps for language learning on the go.

The Role of the Teacher in CALL

While CALL offers numerous benefits, the role of the teacher remains crucial. Teachers act as facilitators, guiding learners through the learning process and providing personalized support and feedback.

Teacher Responsibilities

Selecting Appropriate Technology: Choosing the right media and tools for students, context, and content.
Designing Engaging Activities: Creating interactive and meaningful activities that promote language acquisition.
Providing Feedback: Offering constructive feedback to learners, both on their language skills and their use of technology.
Monitoring Progress: Tracking learner progress and adjusting instruction accordingly.
Fostering Autonomy: Encouraging learners to take responsibility for their own learning.

Challenges and Considerations

Despite its potential, CALL also presents certain challenges and considerations.
