Computer managed learning is a management tool, not a computer based learning system that delivers course materials to the learner. Having said that, with the advent of the World Wide Web some CML applications are now designed to deliver course materials. Primarily, however, computer managed learning programmes are designed to assist large groups of learners, teachers and administration staff.
Rational role of CML
- CML is a controlled system as compared to CAI
- This control raise the motivation of students for longer period of time
- Computerized libraries with control access and remote access as per need
- Use of computer in education was questioned in 1950
- IPI was first project-daily tests and lesson assignments
- Teachers freed from records keeping
Forms of CML testing
- Testing based: offline – tests and decide which lesson to take place next.
- Testing based : online – students are tested via terminals and scoring, analysis and decisions are carried out by CML.
- Non-testing based: control of instructional sequence – teacher prepare assignments, sequence tests for each students, teacher check its daily performance and decide.
- Non testing based : record keeping
Impact of CML
- Detailed assessment of knowledge and achievements via records and reports.
- Supplementing the old strategies with new opportunities offerings
- Master learning principal – achievement constant and time varies (slow learners)
- Computer can judge better for pre- requisite skills prior to actual leaning
- Changes the role of teacher to guide,monitor resource people
Advantages of Online Computer-Based Learning:
- Class work can be scheduled around work and family
- Reduces travel time and travel costs for off-campus students
- Students may have the option to select learning materials that meets their level of knowledge and interest
- Students can study anywhere they have access to a computer and Internet connection
- Self-paced learning modules allow students to work at their own pace
Disadvantages of Online Computer-Based Learning:
- Learners with low motivation or bad study habits may fall behind
- Without the routine structures of a traditional class, students may get lost or confused about course activities and deadlines
- Students may feel isolated from the instructor and classmates
- Instructor may not always be available when students are studying or need help
