COMPUTER-BASED TRAINING TECHNIQUES
Task Requirements
• Ability to teach a physical skill
Recent advances in CBT simulations may allow you to teach physical skills using specifically designed CBT programs. If your employees are to be using expensive or complicated equipment, or working in hazardous environments, CBT can provide "practice" via simulations. With simulations, mistakes, and the learning that results from them, will take place on the computer, not on the job.
• Ability to provide human interaction
Social interactions (conversations between people) are very difficult to teach in the abstract. If your trainees are learning how to use English (or the appropriate spoken language) that is acceptable with supervisors, peers, and clients; follow, clarify, or provide feedback to oral instructions; use aural communications devices; or engage in appropriate social interaction with supervisors, the public, co-workers, or instructors, live, lecture- (or conversation-) based training is probably the best training delivery method. However, recent advances in CBT simulations and video instruction tapes may allow you to use these media for language instruction. In some cases, CBT or video might be an appropriate adjunct to instruction with human interaction.
• Ability to determine and adapt to individual needs
Assessment is a valid part of any training. It enables the training program to target instruction appropriately. Computer-based training assessments may be best at initially placing and then monitoring students' progress within a curriculum. Workbooks and lecturers may also be able to assess learners and gauge their needs. The greatest value of assessment is the guidance it provides on targeting instruction. Good CBT can adapt to learners' individual needs, providing the amount of instructional support needed. Workbooks and lectures can do this to a lesser degree.
• Ability to question students and adjust instruction accordingly
It is important to quiz students periodically to determine whether or not they are mastering the material, and then to adjust instruction accordingly. Well-designed CBT will provide follow-up instruction appropriate to students' responses. Lecturers can also adapt instruction to students' grasp of the course content, but they usually have to target their follow-up to general student needs, rather than to each student's needs. Students using workbooks will probably have to determine what further instruction they might need on their own.
• Ability to provide immediate feedback
It is important for students to know how they are doing and whether they are mastering course content as soon as possible. Immediate feedback can keep them from floundering or going forward under misperceptions. CBT is best at providing immediate feedback. Workbooks and lecturers may also be able to, though not as well.
• Ability to produce life-like images
Some instruction requires high-quality visuals, such as illustrations of machine parts or body organs, to be effective. All of the training media discussed here have that capability, though lecture-based instruction needs some augmentation to provide these visuals.
• Ability to produce high-quality audio
Some instruction also requires high-quality audio reproduction to prepare trainees properly. Machine malfunctions might be best diagnosed by the sounds that they make, and the different sounds people make breathing could indicate different ailments. CBT and video are best suited to providing high-quality audio, and with augmentation, lectures can provide it as well.
• Ability to portray motion
Instruction using motion can demonstrate how something is to be done, for example, assembling equipment or a piece of furniture. CBT and video can clearly show the action, while texts and workbooks can only show pictures at various points in the process. Lectures can be augmented to portray motion.
• Ability to telescope time (time lapse or slow-mo)
Some processes (like the life cycle of a flower) are best shown with time-lapse video. CBT and video can do this extremely well. Conversely, some training may require slowing down time (showing the individual piston strokes of an internal combustion engine, for example). Again, CBT and video do this well.
• Ability to use in combination with other media
Some forms of instruction can be combined fairly easily (lecture with text, for example), some cannot. The ability to combine media may be important if, for example, learners need to master both theory and practice. Textbooks and workbooks are frequently designed for use with other media, while most CBT is designed as a stand-alone product.
• Ability to use computers
Computer literacy is rapidly becoming a basic skill all productive people will need to function in society and on the job. If employees are in jobs that require them to use computers, computer-based training can do double duty: both providing the training content intended, and building employees' comfort and facility with computers. If computers aren't yet used on the job, but will be soon, using CBT will introduce employees to computers and familiarize them with computer functions.
• Ability to teach more than one trainee simultaneously
If a company has a number of people that need to be trained, it is important that the training media work well with groups. All five of the media looked at in this chapter (computer-, video-, text-, workbook-, and lecture-based training) can teach more than one trainee at a time, though trainees would need to be able to access the computer-based training and textbooks individually, and each student would need his or her workbook.
• Ability to provide team as well as individual study
At times, it may be appropriate for individuals to learn how to do something as a group, such as analyzing production processes in order to improve quality. In these cases, it is best that individuals receive instruction together, so that they can share ideas and practice techniques together. Solitary training media, such as texts and workbooks, are not well-designed for team instruction.
• Ability to reach trainees remotely
Trainees may not all be in the same place at the same time. All of the training media discussed in this chapter, except lectures, can handle this situation well.
• Ability to access training where needed
Many organizations are also seeking ways to conduct training without removing employees from their day-to-day job tasks. Again, textbooks and workbooks are most mobile, classroom-based lectures are least mobile. The mobility of computer- and video-based instruction depends on a company's access to computers and VCRs.
• Ability to access training when needed
Many organizations today are looking for a way to train employees when skills are needed. Textbooks and workbooks are most responsive to satisfying the immediate needs of an employee. Lectures are least responsive. CBT and videos can also enable employees to work through an appropriate skill module when the skill is demanded by the job, making them very efficient training delivery methods.
• Ability to update & change course content frequently
If the content of the subject being taught will change frequently, the training media needs to be fairly flexible. If course content is more stable, media flexibility is unnecessary. The lecture format is most flexible, videos and computer-based training least flexible.
