The specific requirements of the research thesis are explained below. As explained in English 111, however, an acceptable thesis for any paper has certain basic features.
The Winged Chariot is a better car to buy than the Tortoise.
Desdemona in Shakespeare's Othello is a strong woman.
Another way to explain a thesis is to say that it states what the essay will be about--two automobiles or a character in a play--and also makes a statement about that subject--that one car is better to buy than another or that Desdemona is strong (and not weak as some readers have claimed).
The Winged Chariot is a better car to buy than the Tortoise because of economy, safety, and options.
Desdemona in Shakespeare's Othello reveals that she is a strong woman through her willingness to marry Othello, her advocacy of Cassio, and her response to Othello's jealousy.
Special requirements for the research thesis
Too broad and vague: The SAT is unfair.
Better: The use of SAT scores as a major factor in college admissions policies is unfairly discriminatory.
Still better: The use of SAT scores as
a major factor in college admissions policies unfairly discriminates against
applicants who do not do well in test situations, whose training has not
prepared them for the specific kinds of material covered by the test, and
who have valuable knowledge and aptitudes not measured by the test.
Unsuitable: Is television harmful to children?
Unsuitable: The harmful effects of television on children.
Better: Excessive viewing of
television is harmful to children because it interferes with their success
in school developmentally, socially, and educationally.
Unsuitable: Marfan syndrome is a congenital heart disease.
Better: Marfan syndrome is the most deadly form of heart disease because it has unusually severe effects on the heart, because its harmful nature is increased by any physical activity, and because it is extraordinarily difficult to detect.
