The following two passages concern the use of “reinforcers,” which are rewards or punish- ments used to encourage desired behaviors, and “contingencies,” which are the arrangements of those reinforcers to shape behavior. PASSAGE 1 “Avoid compulsion,” said Plato in The Republic, “and let your children’s lessons take the form of play.” Horace, among others, recom- mended rewarding a child with cakes. Eras- mus tells of an English gentleman who tried to teach his son Greek and Latin without pun- ishment. He taught the boy to use a bow and arrow and set up targets in the shape of Greek and Latin letters, rewarding each hit with a cherry. He also fed the boy letters cut from GO ON TO THE NEXT PAGE 5.

Privileges and favors are often suggested, and the teacher may be personally reinforcing as friend or entertainer. In indus- trial education students are paid for learning. Certain explicit contrived reinforcers, such as marks, grades, and diplomas, are characteris- tic of education as an institution. (These sug- gest progress, but like progress they must be made reinforcing for other reasons.) Prizes are intrinsically reinforcing. Honors and medals derive their power from prestige or esteem. This varies between cultures and epochs. In 1876 Oscar Wilde, then 22 years old and halfway toward his B.A. at Oxford, got a “first in Mods.” He wrote to a friend: “. . . I did not know what I had got till the next morning at 12 o’clock, breakfasting at the Mitre, I read it in the Times. Altogether I swaggered horribly but am really pleased with myself. My poor mother is in great delight, and I was overwhelmed with telegrams on Thursday from everyone I knew.” The con- temporary student graduating summa cum laude is less widely acclaimed. Although free of some of the by-products of aversive control, positive reinforcers of this sort are not without their problems. Many are effective only in certain states of deprivation which are not always easily arranged. Making a student hungry in order to reinforce him with food would raise personal issues which are not entirely avoided with other kinds of reinforcers. We cannot all get prizes, and if some students get high grades, others must get low. But the main problem again is the contin- gencies. Much of what the child is to do in school does not have the form of play, with its naturally reinforcing consequences, nor is there any natural connection with food or a passing grade or a medal. Such contingencies must be arranged by the teacher, and the arrangement is often defective. The boy men- tioned by Erasmus may have salivated slightly First passage: B. F.

Grades are almost always given long after the student has stopped be- having as a student. We must know that such contingencies are weak because we would never use them to shape skilled behavior. In industrial education pay is usually by the hour—in other words, contingent mainly on being present. Scholarships are contingent on a general level of performance. All these con- tingencies could no doubt be improved, but there is probably good reason why they re- main defective. PASSAGE 2 Even if they don’t study it as a philosophi- cal matter, all teachers must at some point confront the issue of whether, when, and how to punish or reward student behavior. Unless a teacher is blessed with a class full of highly motivated adult-pleasers, it is nearly impossi- ble to avoid the need to nudge students in one direction or another. Simple suggestion works occasionally, but not frequently enough. Rea- soning sometimes works, too, but explaining the logical nuances of behavioral standards is often time-consuming and too often falls on deaf ears. So the practical question becomes: the carrot or the stick? Most educators and psychologists agree that reward is always better than punishment, but a small yet vocal group of psychologists have maintained since the 1960s that reward is often just as harmful as punishment, if not more so. Their arguments are subtle but very persuasive. Educators like Alfie Kohn and psy- chologists like Edward Deci claim that careful study has shown that the introduction of a re- ward system, like gold stars on an attendance sheet or extra recess time for good behavior, changes the nature of the desired behavior completely, and not for the better. For in- stance, Deci conducted a study in which peo- ple were given a puzzle to solve. Some were given money as a “reward” for solving the puzzle and others were simply asked to solve the puzzle. Afterwards, both groups were left alone but watched carefully. Those who had been paid stopped playing, but those who had not been paid continued. Deci concluded that the subjects who were paid probably con- strued the task as being manipulative: the ex- perimenter was trying to get them to do something through bribery. The unpaid sub- jects, however, were more likely to see the task as fun and worth doing for its own sake. This study and many like it have profound implications for the classroom. Several exper- iments have demonstrated that “pay-to-read” programs, where students are given money or certificates to read books, have surprisingly negative effects on literacy. Such programs usually get kids to “read” a lot more books, but their reading skills and, far more impor- tantly, their love of reading decline. Such pro- grams, research suggests, turn reading into a performance rather than a fulfilling personal experience. They encourage students to read books only superficially and only to get the reward. What is worse, like Deci’s puzzle- solvers, the students don’t want to continue reading after the payments stop. Books have become only enrichment for the pocket, not enrichment for the mind. Of course, the human mind is an enor- mously complex machine, and it would be a mistake to use these few experiments to gen- eralize that all rewards are bad. Certainly, honest and mindful praise from a respected teacher can do a great deal to encourage not only good behavior but rigorous intellectual curiosity. Parents and teachers, however, need to be very aware of children’s need to feel in control of themselves. 7. It can be inferred that the “English gentleman” (line 5) believed that good teaching utilized (A) punishment (B) well-written books (C) reward (D) humor (E) careful grading 55 60 65 70 75 80 85 90 95 100 105 110 115 120 125 130 135 CHAPTER 16 / PRACTICE TEST 2 677 8 8 888 8 GO ON TO THE NEXT PAGE 8.
