This would be funny if it were not also unethical and outrageous.

Pearson embedded messages in certain tests to test “social-psychological”premises. Would encouraging messages raise test scores? Would “growth mindset” messages improve scores?

The answer: no.

“Education and publishing giant Pearson is drawing criticism after using its software to experiment on over 9,000 math and computer science students across the country. In a paper presented Wednesday at the American Association of Educational Research, Pearson researchers revealed that they tested the effects of encouraging messages on students that used the MyLab Programming educational software during 2017’s spring semester.

“Titled “Embedding Research-Inspired Innovations in EdTech: An RCT of Social-Psychological Interventions, at Scale,” the study placed 9,000 students using MyLab Programming into three groups, each receiving different messages from the software as they attempted to solve questions. Some students received “growth-mindset messages,” while others received “anchoring of effect” messages. (A third control group received no messaging at all.) The intent was to see if such messages encouraged students to solve more problems. Neither the students nor the professors were ever informed of the experiment, raising concerns of consent.

“The “growth mindset messages” emphasized that learning a skill is a lengthy process, cautioning students offering wrong answers not to expect immediate success. One example: “No one is born a great programmer. Success takes hours and hours of practice.” “Anchoring of effect” messages told students how much effort is required to solve problems, such as: “Some students tried this question 26 times! Don’t worry if it takes you a few tries to get it right.”

“As Education Week reports, the interventions offered seemingly no benefit to the students. Students who received no special messages attempted to solve more problems (212) than students in either the growth-mindset (174) or anchoring groups (156). The researchers emphasized this could have been due any of a variety of factors, as the software is used differently in different schools. However, educators who spoke to Education Week were understandably more alarmed by Pearson placing thousands of unwitting minors in A/B testing for its products.

“It’s concerning that forms of low-level psychological experimentation to trigger certain behaviors appears to be happening in the ed-tech sector, and students might not know those experiments are taking place,” Ben Williamson, a professor at the University of Stirling, told the publication.”

The students who received no “encouraging messages”performed much better than those who did. Maybe the messages triggered anxiety. Maybe they were distracting. Maybe this was a dumb and unethical experiment on human subjects.
