Warren Hardy has been teaching foreigners Spanish for 25 years and his methods work. They're aimed at students who need either basic or functional Spanish—a much less intensive approach than the full immersion method. There's a great deal of substitution drill work and learning the most commonly used verb forms and patterns. It's highly effective, especially for older students who left school long ago. The coursework involves game cards and working with a partner who is roughly the same level of ability. Sessions last 2.5 weeks and run three hours long, three days a week.
