CBT LEVELS

Levels of Interactivity are general classes of richness, sophistication and realism of interactivity the student experiences in the Computer Based Training (CBT). The definitions are applicable to all flavors of e-learning, Technology Based Training (TBT) and Web Based Training (WBT).

When aligning a customers expectations with a vendors vision of the deliverable it is important to construct a prototype as a first step in the process. 

Level 1

This is the lowest (baseline) level of CBT development. It is normally a knowledge or familiarization lesson, provided in a linear format (one idea after another). Sometimes referred to as a "Page Turner". Level 1 is primarily used for introducing an idea or concept. The user has little or no control over the sequence and timed events of the lesson material. Minimal interactivity is provided by frame navigation screen icons. The content may include simple developed graphics and/or clip art. For example a customer powerpoint can readilly be reformulated into Level 1 CBT.

Level 2

This involves the recall of more information than Level 1 CBT and allows the student more control over the lesson’s scenario through screen icons and other peripherals, such as light pens or touch screens. Typically Level 2 is used for non-complex operations and maintenance lessons. Simple emulations or simulations are presented to the user. As an example, the user is requested to rotate switches, turn dials, make adjustments, or identify and replace a faulted component as part of a procedure. However the scenarios are single path scripted and incorrect selections or departure from the required sequence of steps is greeted with context/non context appropriate feedback message. This also may include simple to standard developed graphics, and/or clip art, and customer provided video and audio clips.

Level 3

This involves interaction more complex information models (compared to categories/levels 1 and 2 CBT) and allows the user an increased level of control over the lesson scenario through peripherals such as light pen, touch screen, track ball, or mouse. Video, graphics, or a combination of both is presented simulating the operation of a system, subsystem, or equipment to the user. The lesson scenario training material typically is complex and involves more frequent use of peripherals to affect a transfer of learning. Operation and maintenance procedures are normally practiced with category/level 3 scenarios and students may be required to alternate between multiple screens to keep pace with the lesson material. Multiple software branches (two to three levels) and rapid response are provided to support remediation. Emulations and simulations (constrained models) are an integral part of this presentation, however these are not full free play simulations. This may also include complex developed graphics, and/or clip art, and customer provided video and audio clips.

Level 4

This CBT category/level involves more in-depth recall of a larger amount of information (compared to lower categories/levels) and allows the user an increased level of control over the lesson. Every possible subtask is analyzed and presented with full, on-screen interaction, similar to the approach used in aircraft simulator technology. The lesson material is extremely complex and involves more frequent use of peripherals to affect the transfer of learning. This category/level normally supports certification, re-certification or qualification requirements. Complicated operation and maintenance procedures are normally practiced with category/level 4 and involves all of the elements of categories/levels 1, 2, and 3 plus the following: High degree of interactivity; Extensive branching (four or more levels). ; Levels of sophistication - short of artificial intelligence.
