Americans pronounce modern as MAH-dern (/ˈmɑdərn/). In "modern", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, a small move that separates 'classroom' from 'native'. So instead of MAH·tern, you get MAH·dern. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "Modern technology has changed our daily lives" or "She replaced the old doorknobs with more modern hardware" — more examples below.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "modern", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
Stress falls on the first syllable, not the others. Stretch MAH — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
