I don't know how the ulpans teach today, but those in the 1970s were pretty effective. Or maybe I was just lucky.
I would encourage government radio services to bring back a feature from those days - the nightly news program in "Ivrit Kala" - easy Hebrew. The news of the day, but enunciated more slowly, and a simpler vocabulary. I found it helped me get use to the flow and rhythm of the language. But when I returned to Israel for a refresher in 2005, my teacher had never heard of such a program.
