I read this in order to review it for my Master's degree in TESOL (Teaching of English to Speakers of Other Languages).
As an introductory text, it does an excellent job raising the most important issues in common conceptions of gender and how they affect our lives. There is a bit of dry (but interesting) history as background, but there is also a wealth of information on all of the factors that go into gender - biology, cultural beliefs, popular culture, and more.
Not one person can read some of the chapters in this book without doing a little analysis of how gender is conceived and affected, in both their personal lives or on the grander scale of society. In addition to the wealth of resources from various professional fields, there are much more personal and accessible opinion quotes taken from the author's students. These would serve wonderfully as either thinking points for an individual or an entire group.
Though there were not massive amount of new information for me, someone who studied culture and gender as an anthropology undergrad and deals with culture daily in my job as an ESL teacher for students from dozens of countries, this is an outstanding text for any person, not just younger college students, who has never given serious thought to this absolutely vital aspect of humanity.
