In an experiment in Canada, ten year- old children were put in classes of four sizes: 16, 23, 30 and 37 children in each class. Their teachers said that the smaller classes would result in more individual attention and better marks. However, when the children were tested, those in smaller classes didn’t get high marks than the others, except in mathematics. Moreover, pupils in the large classes said that they liked school just as much. Perhaps the most surprising result was the difference between what the teachers expected and the actual results obtained. More than 90% of the teachers expected the smaller classes to do well. 21. The experiment was carried out in an elementary school. True False Not given No information 22. According to the teachers, students in a small- size class will receive more individual attention and will get better results. True False Not given 23. Children in smaller classes enjoyed attending school more than those in larger class. True False Not given 24. All teachers expected the smaller classes to do well. True False Not given No information 25. What is the passage mainly about? The love of students to their school. Teachers should expect in small- size classes. Larger- size classes are good for children. Mathematics is a good and interesting subject. 26. Which of the following can be inferred from the passage? There are 4 sizes of class in the experiment. Mathematics should be learned in smaller classes. Teachers don’t care about the result. Students must pay attention to the teachers.
