WELCOME EARTHLINGS...

Introduction

At 9 o'clock this morning, as you were walking into your Algebra class, a huge silver UFO overheated and crashed onto the football field!

As the dust and steam settled, a silver sliding door opened and 3 aliens from the planet Nomathus crawled out.

While the unsuspecting freshman were changing classes, the devious aliens crept down the ramp to explore the strange new planet they found themselves on. They made their way to room 159 and stood in the doorway to your classroom. By the time their UFO cools down enough for them to take off again, you are going to have the opportunity to teach them a lesson: The Quadratic Formula.

Task

You are going to do two things for this WebQuest:
  • Complete the first five problems of an online worksheet using the Quadratic Formula with a partner.

  • You are going to come up with a fun way to teach 3 aliens from the planet Nomathus about the Quadratic Formula.

Process

1. First get a general background of the Quadratic Formula by watching and taking notes on the following web sites and resources....

http://www.teachertube.com/viewVideo.php?title=7_2_The_Quadratic_Formula&video_id=260918


2. With your partner, complete the worksheet found below:
http://www.algebrahelp.com/worksheets/view/equation/quadratic.quiz
Your work will be collected, so be sure to write every step down.


3. Now decide for yourself what parts of the Quadratic Formula are important to teach. Make a list of concepts, facts, principles and procedures that are important to know about the Quadratic Formula for the aliens.
4. Decide how you will tailor the lesson for the aliens. How will you deal with the limitations of their vocabulary and previous experience? Why would they want to learn the Quadratic Formula? Make sure these are included in your lesson.

Here are some ideas for you to consider:
  • Provide a glossary
  • Discuss the history behind, or current applications of the quadratic formula
  • Create a fun means of memorizing the formula
  • Show the aliens how to carry out the steps to solving a quadratic using the formula (but be careful not to bore them!)
  • Come up with a metaphor that relates the new information to something they might be familiar with.
  • Think about ways to make the Quadratic Formula more interesting by singing songs or acting out a skit.
Check out these sites for some more ideas!

5. Write out a summary of your proposed lesson. Be sure to include a way to introduce it, a part in which new information is provided, a time in which the aliens practice what they've learned and get feedback, and an opportunity to tie it all together. Be sure to include lots of interaction between you and the aliens.


6. Create the final product and practice your lesson with other members of your class before teaching it to the aliens from Nomathus.

Explanation is difficult to understand and is missing several components OR was not included.
WebQuest Task: Online Worksheet Completion
All problems are completed.
All but 1 of the problems are completed.
All but 2 of the problems are completed.
Several of the problems are not completed.
Creativity
Lesson is fun, engaging and makes the quadratic formula easy to learn.
Lesson is fun and the quadratic formula can be learned with some practice.
Lesson can be used to learn the quadratic formula.
Lesson is not easy to follow, making it difficult to learn the quadratic formula.
WebQuest Exploration
The student has obviously explored the WebQuest fully, using the links to show evidence of understanding the Quadratic formula.
The student has explored the WebQuest and used some of the links to show evidence of understanding the Quadratic formula.
The student has not fully explored the WebQuest but has used some of the links to show limited evidence of understanding the Quadratic formula.
The student has obviously not explored the WebQuest fully, and is unable to show evidence of understanding the Quadratic formula.







Conclusion
Now that you are the master of the Quadratic Formula yourself, you can teach others too! Even if the others happen to be from another planet, like the aliens from Nomathus!
Tomorrow we will begin teaching the aliens our lessons. Hopefully, you enjoyed learning about the Quadratic Formula and are ready to learn some more. Unfortunately, the UFO has cooled off and the aliens are ready to return to the planet of Nomathus (along with their knowledge of Earth and the Quadratic Formula).
