参観

1. Origins, structure, and basic meaning

• Structure: 参観 is read as さんかん and is a noun and する verb for visiting and observing a lesson, operation, or other organized activity.
• Basic usage: The observed activity appears in 授業を参観する, while prior timing appears in 作業を参観する前.

2. Common pitfalls and similar expressions

• Observation and participation
  • The focus is watching the activity on site, not taking part in the lesson or work itself.
• Difference from 見学
  • 見学 broadly means touring or observing to learn; 参観 readily describes visiting to observe a lesson, work process, or other organized activity in progress.
