In a classroom in Namibia's northern Oshikoto region, a teacher has written English vocabulary words on the chalkboard. She asks her learners to read them aloud. When they stumble with pronunciation, she corrects them. She also helps the youngsters to sound out words. At another school nearby, an English teacher is showing her class cartoon strips on her cellphone to help them create mental images while reading—an approach that's proven to enhance comprehension.
