A strong problem statement declares what is not yet known and states it clearly. Paste yours below and see where it holds together and where it needs work.
Accepted openers, drawn from your problem space and literature review:
• “It is not known how or why [gap]…”
• “While the literature indicates [what is known], it is not known in [school / district / organization / community] how or why [gap]…”
• “Based on what is known in the literature, [gap] is still unknown or still needs to be understood…”
The declarative sentence (or two) that states the gap.
