Final answer:
The most effective method to train food service employees on making a new sandwich is to demonstrate the process, while schools prepare children for the workforce using a standardized curriculum, the hidden curriculum, and socialization in teamwork.

Step-by-step explanation:
The best way to train food service employees on making a new sandwich would be to demonstrate the process. This hands-on approach is effective as it allows employees to visually comprehend the steps, ask real-time questions, and practice under supervision before attempting to make it on their own. Providing written instructions only or conducting a written test can be supplementary methods, but these lack the interactive component essential for mastering a physical task. Allowing employees to figure it out on their own can lead to inconsistent results and may not adhere to the restaurant's standards.
