Outcome Design





Outcome design

I am going to introduce the knowledge about fractions. I want the learner to be able to deal with fractions, which means they can analyze and calculate fractions. I will focus on the following three points:

  1. Specific – is my outcome fuzzy or clear?
  2. Measurable – is there a way to assess the product of this outcome? Think about how I will assess this product.
3.    Actionable – is the learner doing something to demonstrate the outcome for the cognitive, affective or psychomotor domain of learning? Is it student-centered and at a higher level of learning?

Upon completion of learning fractions, the

learner will be able to deal with fractions themselves at a higher level.
Fractions
Category
Example and Key Words
Definition: What is a fraction?
Examples: 
Key words: Part of a whole. A number written with the bottom part (the denominator) telling you how many parts the whole is divided into, and the top part (the numerator) telling how many you have.
Meanings: What does a fraction mean?
Examples:




Key words: They are equal parts of a whole.
Compare: How to compare fractions?
Examples: 


Key words: If they have the same denominator, then the bigger the numerator, the bigger the fraction. If they have the same numerator, then the bigger the denominator, the smaller the fraction.
Calculate: How to add/subtract or multiply/divide fractions?
Examples: 


Key words:
Addition: if two fractions have the same denominator we may add them by adding the numerators.
Subtraction: If two fractions have the same denominator you compute their difference by subtracting the numerators. If the fractions have unlike denominators first rewrite the fractions over a common denominator. Then compute the difference by subtracting the numerators, putting the answer over the common denominator, and reducing to lowest terms.
Multiplication: Using the multiplication of numerators divides the multiplication of denominator.
Division: Using the dividend multiplies the inverse of the divisor.

While teaching the knowledge about fractions I suggest students to do some practice online. There are lots of math games or fun practice in the internet, like http://www.ixl.com/math/grade-8 which is a formal website about math.

Or I could take a video of fraction lesson, then they can reply it after class. I understand that there are students cannot get the knowledge at the class, because I had a hard time with physics in my middle school. And also they can discuss it with me in the class blog, which is timely and efficiently.
