The u in educate starts with a short y sound, as in you. When d meets that y, the two melt into j. The same thing happens in gradual, procedure and individual, and in the American way of saying schedule.
The ending matters too. After a t or a d, -ed is a full extra syllable, as in wanted and needed. So educate has three syllables and educated has four. In American English the t becomes a quick tap, close to a soft d.
The stress stays at the front: EJ. In education it jumps to KAY: ej-uh-KAY-shun. Practise the pair so the stress does not slide.
