=10.5pt=14ptResearch taught one group of students a new mathematical system using abstract symbols, such circle and diamonds, and another group using concrete scenarios, such as combining liquids in measuring cups. The students who learned the system using symbols later performed much better than the others, on average, in a children's game, requiring them to apply their knowledge in a new situation. The researchers concluded that the specific details of the concrete scenarios had distracted the other group from the underlying mathematical concepts.
=10.5pt=14ptWhich of the following, if true, would most weaken researchers’ reasoning?
=10.5pt=14ptA The children's game used symbols in a way similar to the way the abstract symbols had been used in teaching the first group of students.
=10.5pt=14ptB When the experiment was repeated with new students who all played the game before being taught the mathematical system, both group reported played equally well.
=10.5pt=14ptC Several students in the first group reported that the abstract symbols had distracted them from the underlying mathematical concepts.
=10.5pt=14ptD The first group of students did not perform better than second on task that were identical to the concrete scenarios with which the second group had been taught.
=10.5pt=14ptE The children's game primarily involved combining liquids in measuring cup.
