Computer assisted learning advantages and disadvantages

Computer-assisted language learning (CALL). and computer assisted learning in education | free ppt download
Computer Assisted CAL Learning 1Referred to as CAL Term often used interchangeably with Computer- Based Instruction (CBI), Web Based Instruction (WBI), Computer-based Learning (CBL), Computer-Enriched Instruction (CEI), and Web Based Training (WBT) 23 INTRODUCTION  Computer-assisted language learning (CALL) is succinctly defined in a seminal work by Levy (1997: p. 1) as "the search for and study of applications of the computer in language teaching and learning".  Definition- Any use of computers to aid or support the education or training of people.4The computer can be made to assist learning in many ways: ▫ Dense storage of data in an organized form, e.g., a large textbook could be stored in a classified manner on a 13 cm. disk. ▫ Quick access to the data-base in milli-seconds. ▫ Logical comparison of the learner's responses with the stored key and evaluation of the learner's performance. ▫ Instant feedback of evaluation (both formative and summative types). 5To keep the education system at the forefront 6 of technological development and students’ skills up to date with those expected in the workforce. To increase efficiency and productivity in teaching and learning. Goals of To enable more self-directed learning with students as active learners assisted by teachers to construct their own Introducing understanding. With the visual power of simulation Computers into available in a computer, it can generate images which can help students to understand "Why things are the way they Education are". By using computers in instruction, information can be displayed effectively which enables students to understand concepts easily.Traditional Teaching A single teacher giving lectures to a group of students who are expected to use their notes and textbook to prepare for periodic examinations 7“ CAL Teaching The computer can never replace a teacher. It merely complements a teacher's role. However, in some areas of interaction, it may be better than a human teacher. e.g., ▫It never gets bored or irritated ▫ It never makes mistakes on its own ▫ It permits individual attention ▫ It permits the learner to decide his own pace of learning. ▫ A well created lesson uses multi-media to enrich and enhance learning 89 Classroom for CAL10 Methods Of Delivery ▫Drill-and-Practice ▫Tutorial ▫Simulation Activities ▫Educational Games ▫Problem Solving ▫Controlled Learning ▫Computer Programming11 Drill And Practice  Drill and practice is good for fundamental mastery.  It provides repeated exposure to facts or information, often in a question or game-type format (e.g., use an MCQ bank for practice).  It also fit nicely into a behavioral approach to teaching and learning since it measured student performance.12 In this mode, a module (lesson)consists of presentation of the content in a structured way , task- Tutorial prescription to elicit learner's response, and instant feedback and reinforcement to the learner. This mode, if used well, could result in 90% retention of the content (compare with 30% retention after the best lecture). Students who are absent or who need remediation can often benefit from using a computerized tutorial, provided one is available that covers what was missed Combines presentation of material with drill-and- practice, games, or a simulation to emphasize material and assist in learning.13 Simulation A simulation is a representation or model of a real event, object, or phenomenon where learners can see the results of their actions. It provides a real-life scenario with the material to be learned being applied as it would in the real world. Simulation provides safety of learning environment Students are given the power to manipulate aspects of models or situations. They see the results of their decisions immediatelyProblem Solving  Problem solving software allows learners to see the results of their reactions to various events  Learners manipulate variables, and feedback is provided based on these manipulations  There is a lot of power to using problem solving applications in the classroom, provided they match the curriculum  It is sometimes otherwise difficult to provide feedback based on individual choices students without the computer.15 Educational Games Games use the instructional material to create a contest for the learner The learner can compete against his own personal best, the computer, or other learners while mastering the material16 Computer Programming (Logo, BASIC, Pascal) ▫This used to be a big category of computer use in the schools, but the emphasis on programming skills has decreased significantly. ▫Many schools no longer even offer programming classes, but instead are teaching students to use multimedia and other computer tools.17  It provides a course of study in an Controlled instructional sequence on the pattern of branching program LearningTOOLS  Spreadsheet program  Statistic packages  Hypermedia software  Desktop publishing software  Presentation software  CAD software 18ADVANTAGES  Reduced the work load of teaching.  Improve motivation  Reach the large audience  Multiple dimensional learning  Promote interactive learning.  Builds confidence among students.  Provide immediate feedback. 19DISADVANTAGES  The development of high‐tech computer‐assisted learning programme is labor intensive, requiring appropriate hardware, backup and frequent upgrading.  In addition, a dedicated information technology staff is necessary to provide practical advice and maintenance of the software and hardware.  Some people may be less inclined to use electronic resources because of perceived lack of computer literacy. 20Future TrendsWhile research is still ongoing into the effectiveness of CAL for medical education, this new learning modality is a rising form of medical teaching. • The Association of American Medical Colleges (AAMC) has established MedEdPortal, a peer-reviewed collection of online teaching tools. • This resource contains a database of learning resources that include tutorials, virtual patients and case-based learning among other medical education resources. 22Continued.. Between the conveniences afforded by CAL, enhancements over current learning modalities and increased recognition for publishing CAL modules, there appears to be a bright future for computer-assisted learning. 23Thanks Any questions?
