TRAINING DESIGN FRAMEWORK

The 4C/ID model is proposed for training design to help trades personnel gain appropriate skills with AR/VR wearables. It considers four components in instructional design: Learning Tasks, Supportive Information, Procedural Information, and Part-task Practice. Each component supports the development of complex skills or professional competencies. 

1. Learning Tasks

Learning tasks are cases, projects, tasks the learner performs in real-life of simulated environments. They integrate the skills, knowledge, and attitudes required from simple-to-complex task classes. Built-in scaffolding diminishes as a learner becomes competent in one class level. 

Ex. Teaching an electrician how to install a new equipment

​

2. Supportive Information

Supportive Information assists students in non-routine tasks by providing guidance on problem solving, reasoning, and/or decision making. They include cognitive strategies on problem solving approaches and mental models of the knowledge domain. These feedback help learners establish an in-depth understanding of the relationship between newly presented information and what they already know. 

Ex. Provide additional information on different parts of the equipment and their functions throughout the installation process.

​

3. Procedural Information

Procedural Information are the just-in-time information in the form of "how-to" or "step-by-step" instructions to guide the learner in performing a task. They are best suited for routine tasks. These instructions should be specified at a basic level that can be easily understood by learners. The instructions gradually fade after extensive practice. 

Ex. AR overlay of step-by-step instructions for installation

​

4. Part-task Practice

Part-task practice are designed to provide additional practice to reach automaticity on highly recurrent tasks. 

Ex. The installation for this new equipment requires worker to build multiple identical assemblies. Part-task Practice is used to help workers gain familiarity with this repetitive task.
