Feminist archaeology is an approach to studying ancient societies by critiquing what its practitioners perceive as an androcentric bias both in many past civilisations and also in modern archaeological study. They attempt to rectify it by producing new interpretations that promote a greater role for women in the past than that which has been traditionally attributed. Androcentrism (Greek ανδρο, andro-, man, male, χεντρον, kentron, center) is the practice, conscious or otherwise, of placing male human beings or the masculine point of view at the center of ones view of the world and its culture and history. ...

Feministarchaeology, in a nutshell, is archaeology that focuses on the activities and roles of women within the society being studied.
There is a mainstream of archaeology, unfortunately one that is not often seen by the generally public, and this mainstream incorporates the good of these different schools of thought, typically rejecting the bad (though it sometimes takes a while), and producing an ever stronger and more nuanced and realistic portrait of the human past.
Moreover, without feministarchaeology specifically, it is unlikely that the nature of power dynamics within a household or gender and age roles within a culture would ever have become important fields for research.
