|Teaching & Assessing 21st Century Skills
As the 21st century unfolds, the pace of change in the world is accelerating. The authors believe a combination of cognitive skills (skills students will need to succeed academically) and conative skills (skills students will need to succeed interpersonally) is necessary for the 21st century. This clear, practical guide presents a model of instruction and assessment based on these skills.

- Although they look curved, these lines are actually perfectly parallel. The sunburst pattern in the background makes them seem curved.
- In this illusion, all of the diagonal lines are parallel, even though the vertical and horizontal lines make them look otherwise.
- These horizontal lines are perfectly parallel, but the offset black and white blocks make them seem to curve.
- The ring in the center is a perfect circle, but the lines behind it make it seem pear shaped.
- This square has straight sides, but the rings in the background make it look as if the sides are bent in.
- These lines are perfectly parallel, but the image behind them makes it look like they bend away from each other at the ends.
- These horizontal lines are the same length, but the diagonal lines make it seem as if the top one is longer.
- The center circles of each flower are exactly the same size. The size of the surrounding circles makes you think that the circle at the center of the small flower is bigger than the one at the center of the large flower.
- Although the soldiers are exactly the same size, the one on the left looks shorter and the one on the right looks taller because of the background against which they are shown.
- Here you will either see three white lines or a three-dimensional letter E.
- Here you will either see two faces or a white vase.
- This is either a seal with its tail in the air or a horse’s head.
- This is either a young woman looking away from you or an old woman resting her chin on her chest (the young woman’s chin becomes the old woman’s nose).
- This can be either a duck or a bunny. The duck’s bill becomes the bunny’s ears.
- This is either a Native American head in profile or an Eskimo peering into a dark cave.
- There are actually three pictures here. A young girl with shoulder-length hair is looking away from the viewer, an old woman with a sad smile is looking down and to the left, and a man with a moustache is looking to the right (the girl’s chin becomes the old woman’s nose, and the girl’s hair becomes the mustached man’s nose).
- In this picture, which looks like a collection of random dots, there is Dalmatian dog sniffing the ground. He is facing to the left and has his head down.
