Can someone please help me understand what “thinking dialectically” actually means?

I’m reading through The Curriculum of Basic Principles of Marxism-Leninism at the moment so I’ve been trying to get my head around this lately. It would be super helpful if someone could, say, talk about some historical political development or some contemporary issue and tell me examples of what an idealist, nondialectical materialist, and dialectical materialist analysis of that issue might look like? Thank you 🙏
