- The data you collect from these clicker questions will help you gauge student comprehension of material.
- Research suggests that students’ learning in the first few weeks of the course can strongly impact their subsequent performance.
- Students who perform poorly in the beginning of the course tend to perform worse on the final exam.
- The clicker questions that Porter, Zingaro, and Lister found to be most useful for identifying students who needed additional help in a CS1 class are as follows:
- What is the value of x after this code runs?
x = 0 if x < 5: x = 4 if x > 2: x = 1 else: x = 3A. 0 B. 1 C. 4 D. 3 E. 5 - What is printed by this code (the value of sum)?
lst = [ [2, 3, 4], [1, 1] ] sum = 0 for i in range(len(lst)): for j in range(len(lst[0])): sum = sum + lst[i][j] print(sum)A. 2 B. 7 C. 11 D. Error due to bad list reference - What is the output of this code?
def calculate(w, x, y): a = x b = w + 1 return a + b + 3 print(calculate(3, 2, 0))A. 5 B. 9 C. 0 D. 3 -
if temperature > 0: print("above freezing") elif temperature == 0: print("at freezing") else: print("below freezing") Does the code below do exactly the same thing as the code above? if temperature > 0: print("above freezing") elif temperature == 0: print("at freezing") print("below freezing")A. Yes B. No - What is the output of this code?
def a(num): return val + num + 3 def b(val): return a(1) print(b(2))A. 6 B. 7 C. 4 D. 5 E. Error because of an undefined variable
- What is the value of x after this code runs?
