This document discusses teaching the preterit and imperfect tenses simultaneously rather than in isolation. It notes that authentic Spanish texts use both tenses together, but textbooks traditionally teach them separately. The authors implemented an approach where students learn about and practice with both tenses from the beginning. This provides students with a more natural experience that avoids confusion and frustration. Students are able to produce simple speech and writing incorporating both tenses earlier in their learning. The approach also reduces students' fear of making mistakes.
