Structured Word Inquiry (SWI)
SWI is a research-validated approach developed at the University of Manitoba. Rather than drilling letter-sound correspondences, SWI teaches students to investigate words using four questions.
The Four SWI Questions:
- What does this word mean? (Use it in context)
- How is it structured? (Identify morphemes: prefixes, base, suffixes)
- What are related words? (Word family evidence)
- How is it pronounced? (After meaning and structure are established)
<sign> + <al> → signal
<sign> + <ature> → signature
<de> + <sign> + <ate> → designate
