Unit 3

Understanding the Organization of the Text

(1) Introduction (para 1)

It has been proven repeatedly that the various types of behavior, emotions, and interests that constitute being masculine and feminine are patterned by both heredity and culture.

(2) There is a cultural bias in education that favors boys over girls. (para. 2-4) Supporting evidence

A. Teachers called on males in class far more than on female students. (para 2)

i) Its consequence: This has a tremendous impact on the learning process.

iii) Two examples:

a. In many of the former all-women’s colleges, the boys were taking over the

class-room discussions and active participation by women students had diminished noticeably.

b. A similar subordination of female to male students has also been observed in law and medical school classrooms in recent years.

B. Teachers assigned boys and girls different tasks according to stereotyped gender roles. (para. 3)

i) Its consequence: This prevented girls from participating as actively as boys in class. ii) An example: A teacher had the little boys perform the scientific experiment while the girls were given the task of putting the materials away.

C. Gender-biased education is also reflected in the typical American teacher’assumption. (para 4)

i) The assumption: Boys will do better in the hard, masculine subjects of math and science while girls are expected to have better verbal and reading skills.

b. In Germany, all studies are considered masculine and it is girls who develop reading problems.

c. In Japan, where early education appears to be nonsexist, both girls and boys do equally well in reading.

(3) The educational bias begins at home. (para 5)

A. Supporting evidence:
