Paths to teaching/lecturing careers?

Hey y'all, I am a rising 4th year undergrad in Materials Science and Engineering. I've been doing research as an undergrad for about 2 years, and I think I've decided that doing a PhD is not for me. I don't think I have the independent self-starting mindset required for research, and I don't envy the lifestyle of the PhD students around me. However, I love the environment of "academia" and I want to stay in some way engaged with science and the generation/communication of new knowledge.

So recently I had a "what am I doing with my life" crisis, and I thought about becoming a lecturer, someone who teaches classes without the burden of running a research lab. I like the idea of teaching an introductory materials science or chemistry or physics course. I wanted to ask some questions about this career path:

• Most places I look say that a PhD in the STEM area is required to become a lecturer at an R1 university. But one lecturer I talked to suggested a PhD in education may also make me a good candidate. Does that have merit?
• Is it true that to teach at community colleges, only a Master's may be required?
• Is it feasible to teach part-time and hold an industry position at the same time?
• Are there other STEM education-related positions that aren't as "you-need-to-go-to-grad-school" heavy?

Thank you!
