Thanksgiving...

The WBST is designed to assess the basic verbal and mathematical skills required for nonprofessional jobs. Quantitative skills are measured in terms of practical mathematical applications and verbal ability is measured in terms of reading comprehension, word knowledge, grammar, and sentence construction. The test is taken using pen and paper and then scored using PC software.

Verbal skills, 20 minutes;
quantitative skills, 25 minutes

Mathematical Skills

This portion of the Wonderlic Basic Skills Test contains about 45 items. You are asked different questions focusing upon the basic mathematical concepts such as addition, subtraction, multiplication and division. The questions may take different turns depending upon your applied jobs. Generally, the tester may try to find out:

1- Can you apply the basic mathematical functions upon whole numbers, fractions, and decimals?

2- Can you apply basic functions upon whole or fractional monetary units?

3- Can you apply your basic mathematical knowledge upon measurement units such as time, length, width, weight, distance etc? The units may be in the shape of whole numbers or the fractional ones.

4- Can you apply your knowledge upon ratio, percentage and other such functions?

5- How much developed skills you have in Algebra?

6- How much grasp you have upon basic geometrical concepts?

The Wonderlic Basic Skills Test is widely used psychological instrument. However, the USA labor department gives it more importance than any other labor department in the world. That’s why the US labor department has specified six different job levels for the different levels of Wonderlic Basic Skills Tests. While encountering a Wonderlic Basic Skill Test, you must keep in mind that it is not your speed of answering but correct choices which makes you fit or unfit for your applied job.

Population Growth

How quickly is the human population changing? Check out this world map timeline to get a sense of world population growth. Do you think that the population growth rate is too fast? Why?

Let's look at some maps and charts to better understand the issues.
  • Look at the map and observe the differences in Population Growth Rate in different parts of the world. Then answer the questions below the map in the left box. Click on the 'Check Your Answer' to see correct answers in the right box. If you don't understand the answers (or questions) ask Professor Lewis for some more explanation.
  • Do the same thing for the Population Momentum chart.
Now let's do an activity based upon the Nova program, "World in Balance." Everyone will be working in groups of three for this activity.
  1. In the handouts, each group will choose one country from each continent. We will make a list of all of the countries on the screen.
  2. Assume a starting population of 50. Do the population growth calculations for each country as described on the second page of the handouts.
  3. Once each population has doubled, stop the calculations.
  4. Report the amount of time it took for each country's population to double to Professor Lewis.
  5. Graph the population data (like we have been doing each class) for each country.
  6. Why do you think different countries have different growth rates?
