COMPUTER ASSISTED LANGUAGE LEARNING (CALL)
PAUL GRUBA (CHAPTER 25)
Computer Assisted Language Learning (CALL) Definition:
“the search for and study of applications of the computer in language teaching and learning” (Levy, 1997, p.1)
A broad definition would be:
an approach to language teaching and learning in which computer technology is used as an aid to the presentation, reinforcement, and assessment of material to be learned, usually including a substantial interactive element.
Main Objective of CALL:“improve the learning capacity of those who are being taught a language through computerized means” (Cameron, 1999a, p.2)
A Brief History of CALLCALL’s origins can be traced back to early experiments in the 1960s.The advent of microcomputers in the late 1970s resulted in a boom in the development of CALL programs.A major landmark in the history of CALL was the advent of the World Wide Web.Most of the CALL programs that were produced in the early 1980s consisted of a series of drills, multiple-choice exercises, and Cloze exercises, focusing on grammar and vocabulary. Then nondrill-based approaches added to CALL.
The applications tend to fall into two distinct types:
• (a) those that involve the use of generic software tools such as word processors, presentation software, e-mail packages, and Web browsers, and
• (b) those designed specifically to promote language learning. This type falls into the category of Computer Assisted Language Learning (CALL)
Connectionist model:CALL Typology :
1) programs that focus on traditional exercise types such as multiple-choice, gap-filling, free-format, reordering, and Cloze; and 2) programs such as simulations and adventures, action mazes, text manipulation, and exploratory programs.
Davies and Higgins (1982 , 1985)
According to (1) and (2): programs focus on (a) grammar or vocabulary; (b) the four essential language skills of reading, writing, listening, speaking; with (c) separate categories for adventures, exploratory programs, and authoring programs.
Connectionist model:Four broad categories of CALL by Hardisty and Windeatt (1989)
• School: traditional exercise types• Office: generic programs such as word processors and
communications software• Library: concordancing programs• Home: games such as simulations and adventures

Integrative CALL (twenty-first century)
Integrative CALL: This phase is marked by two important technological developments:
- Multimedia personal computers (MPCs), which enabled reading, writing, speaking, and listening to be combined in a single activity, with the learner exercising a high degree of control over the path through the learning materials.- The Internet, which offered new opportunities for computer-mediated
communication (CMC) between learners and teachers, and a wide range of activities centered on the World Wide Web.
- Integrative CALL seeks to use networked computers as a means to engage learners in meaningful, large-scale collaborative activities.
Agency: is a power to take meaningful action and sees the result of decisions and choices.
Key difference in communicative CALL (C-CALL) and integrative CALL (I-CAll):
C-CALL: Task-based approaches to syllabus design direct learner choice and self-management. Syllabus is designed in advance according to learner needs.
I-CALL: syllabus is dynamic and learning happens through “accidents” produced by projects.
Role of Computers, Students, Teachers, and Researchers
Structural/behavioral stage(CALL): Role of Computer: computer is as “tutor” who patiently delivered repetitive drills
Materials: focus on technology
Role of learner: students were dependent of programs which delivered grammar and vocab
Role of Teacher: the teacher often served as a mediator between the computer and students.
Role of researcher: they examined ways in which the use of the computer helps with the efficacy of instruction.
Role of Computers, Students, Teachers, and Researchers
Communicative CALL: Role of Computer: computer is as “pupil”. Practitioners used computer to stimulate conversations amongst students
Materials: served as prompts for both discussion and practice
Role of Learner: learners had independent relationships with computer, learners had interactive relationships with applications
Role of Teacher: the teacher often served as a mediator between the computer and students.
Role of researcher: investigation focused on variety of factors which were thought to influence the “distributed cognition” amongst computers, learners, and instructors.
Role of Computers, Students, Teachers, and ResearchersIntegrative CALL: (including networked-based and socio-cognitive approaches)
Role of Computer: computer is “unified information manager” with a lot of applications. Computer environment can create “social space”
Role of learner: students work collaboratively (in groups) and use computer as “toolbox” for group project work.
Role of Teacher: teacher has less intrusive role, and can deepen students’ understanding between text and context
Role of Researcher: sociocultural theories of language learning and second language acquisition gained focal attention.
Electronic Literacy Framework
Three areas:
1. Communication: learners must be able to interact and collaborate
2. Construction: students should know how to blend written text, graphics, audio and video together.
3. Research:

Early CALL
Early CALL programs – many of which fell into Warschauer’s behavioristic category which simply presented a series of stimuli to which the learner had to respond.
the stimulus was usually in the form of text displayed in monochrome on a computer screen, and the only way in which the learner could respond was by entering an answer at the keyboard, either by entering a letter or number as a response in a multiple-choice exercise or by typing the answer in full as a response in a free format exercise. Such programs consisted mainly of a sequence of repetitive drills.
Communicative Call
Before Communicative CALL, teacher-centered, drill-based approach was important. Computer was provider of drills.
But later learner-centered, task-based, or explorative approach became important.
the computer was as an informant, with the learner asking the questions and the computer providing the answers.
Multimedia CALL
- stimulus could now consist of any combination of text, still images, sound, and motion video.
- CD-ROMs
- All of these offered the learner the opportunity to record and playback his/her own voice.
Web-based CALLIn 1992, the World Wide Web was launched, reaching the general public in 1993. It offered remarkable changes to teaching and learning, such as Web-based multimedia, integration of CD-ROMs and the Web.
Whole-Class Teaching and CALL
- Teacher brings a single computer and a large TV monitor into the classroom and teach the whole class, using the TV monitor as the focus of attention.
- the interactive whiteboard, a touch-sensitive projection screen
