Imagine that researchers publish a study that shows the following positive correlation: College students who spend more money on new clothes tend to have more friends. Which of the following represents a plausible explanation for this correlation?

1.Spending more money on new clothes makes college students more attractive to potential new friends.

2.Having a lot of friends to go shopping with makes college students spend more money on new clothes

3.Wealthy college students have more money to spend on new clothes and more money to do fun things with friends.

4.All of these are plausible explanations for the correlation.

Bruner and Revuski's research with high school students pressing telegraph keys showed that

1.people can easily develop superstitious behaviors without even being aware of it.

2.people are much smarter than pigeons.

3.earning a nickel is not an effective reinforcement for most high-school students.

4.superstitious behaviors are just as easy to extinguish as they are to learn.

How did Skinner create "superstitious" pigeons?

1.By punishing the pigeons randomly.

2.By using shaping and chaining techniques to train the pigeons to deal out tarot cards.

3.By giving the pigeons regular noncontingent reinforcement (rewards that didn't depend on their behavior).

4.By reinforcing the pigeons whenever they engaged in "superstitious" behavior such as stepping over lines drawn on the floor of their cages.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
