Question: When introduce technical vocabulary: before, during, or after reading?
Answer: Before and after reading, teachers presented the words in a sentence, using an overhead projector, and then discussing meaning of the words in class. Students used a glossary during reading. No statistically significant differences in the three methods.
Comment: I still prefer pre-teaching technical vocabulary. Students are alerted to it and see and recognize it. I have done some experiments and found that students did not see or recognize the technical terms when reading if not pre-taught. RayS.
