GRE

GRE (Graduate Record Examination) Score received by the applicant

GPA

Undergraduate GPA scored by the applicant

RANK

Rank of the undergraduate school, Institutions with a rank of 1 have the highest prestige, while those with a rank of 4 have the lowest.

 

You have been tasked to develop a model to predict candidate’s admission to the program that the school could potentially use to develop a new recruitment campaign. The school understands that targeting the right students would result in saving money in their marketing endeavor.

  • Know what resources are available for independent and personalized learning.
  • Know how to navigate the Internet in search for experts who might be good mentors for you.
  • None of the above.

  • Leadership.
  • Facilitating diverse groups of people involved in a project.

 
 
Question 6
2 / 2 pts
According to Daniel Pink, basic left-brain abilities such as being logical, linear, and sequential still matter, but they matter less; a different set of abilities matter more. Those abilities are:

  • right-brained abilities such as artistry, empathy, inventiveness, and big-picture thinking.
  • mid-brained abilities such as communicating, collaborating, and critiquing.
  • brain-stem abilities such as realizing when an idea has been exhausted and knowing when to start over.

Pink believes the skills required for future jobs will involve dealing with novelty, nuance, and customization. With this in mind, he suggests educators ________the relying on routines, right answers, and standardization.

  • rely more heavily on
  • move away from

 
Question 10
2 / 2 pts
The six abilities that matter most in the 21st century, according to Pink, are design (not just function), story (not just argument), non-routine, symphony/big picture thinking and putting the pieces together (not just focus), empathy (not just logic), play (not just seriousness), and meaning (not just accumulation). For educators, this means that learners should ______________ new metrics/ways of measuring, get real about STEM (science, technology, engineering, and math) where problems are poorly defined, multidisciplinary, and has multiple answers, none of which are perfect. 3) tear down the walls between disciplines and between the walls in the schools, 4) infuse arts education throughout the curriculum, and 5) promote and defend autonomy.
