Questions & Answers about Αυτό το μάθημα έχει μεγάλη αξία για το μέλλον μου.

- a demonstrative: αυτό = this
- plus the definite article: το = the
So αυτό το μάθημα literally looks like this the lesson, but that is the normal Greek structure for this lesson.
You will see this pattern very often:
- αυτό το βιβλίο = this book
- αυτή η μέρα = this day
- αυτό το σπίτι = this house
