Definition 1.3. A type n complex is a finite spectrum satisfying K(i)∗X = 0 for i < n and K(n)∗X , 0. By a theorem of Mitchell [6, Thm B], there exists a type n complex for every n. Definition 1.4. Let X be a finite spectrum. A map v : ΣdX → X is a vn self map if it satisfies K(i)∗v = 0 for i , n and K(n)∗v is an isomorphism. By a theorem of Hopkins-Smith [2, Thm 9], every type n complex admits...

15 صفحه اولon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
