McMillan dan Schumacher

Berikut teori menurut McMillan dan Schumacher (2001:5-6) yang mengemukakan enam alasan penting penelitian di bidang pendidikan, yaitu:

1. educators are constantly trying to understand educational processes and must make professional decissions.
2. noneducational policy groups, such as state and federal legilatures and courts, have increasingly mandated changes in education.
3. concerned public, profesional, and private groups and foundations have increased their research activities
4. reviews of prior reasearch have interpreted accumulated empirical evidence
5. educational research is readily available
6. many educators who are not full-time researchers read research and conduct studies.
