Answer:

Overlapping of experiment groups

Explanation:

Dr Smyth research is intended to analyse whether preschool children learn new words faster with pictures or objects.

He makes all the children participate in learning through picture & object tools both. And, concludes that object tools condition gives better results.

However, his design & conclusion is flawed. As, he overlapped the same group of children to test through both the learning methods (pictures & objects).

  • When children are indulged in both methods, their learning is likely to be cumulative effect of both the methods. Its very difficult to segregate the learning impact owing to individual method & compare them.
  • Creating different student groups, for learning through the two methods -  is a better option. Two distinct groups taught through the 2 different methods, & their learning analysis would give better study result about the methods' comparative efficiency.

Westkost [7]

Answer:

These are the options for the question:

A) Russia

B) Germany

C) Rhine River

D) the Pyrenees

And this is the correct option for the question:

D) the Pyrenees

Explanation:

The Pyrenees by definition, are not part of the Northern European Plain because it is a mountain range. The Pryenees forms the natural boundary between the Iberian Peninsula, and the rest of Europe (Europe is also a big peninsula), where the plain is located.

Germany on the contrary, has around a third of its territory in the Northern European Plain, the Upper Rhine River is located entirely within the Northern European Plain, and most of Western Russia is located within the Northern European Plain.
