Identifying similiarities and differences might be the "core" of all learning.

It enhances students' undestanding of and ability to use Knowledge.

Teachers essential questions while they are implementing Marzano's strategies in the classroom can be as the following:

  • What are the similiarities and differences relative to the content in my curriculum?

  • How can I get my students to recognize and understand them?

Well, there are four effective forms to identify similiarities and differences proposed by Marzano. In addtion, these strategies can be accomplish by the use of technologies such Power Points, Smart board, special sofware as kidspiration, Excel, Microsoft Word, and Websites.

  1. Comparing Is the process of identifying and articulating similiarities and differences among items.

The most classic graphic organizers for comparing are:

  • Venn Diagram

It is most useful when comparing two items.

  • Comparison Matrix

2.Classifying→ It is the technique of grouping things that are alike. The teacher can ask the students to groups things into categories based on their characteristics.

For example,

Teacher can use this graphic when items are not equal -------------------This graphic can be use by a teacher when all item share one general idea.

3.Creating Metaphors It is when two items are conected by an abstract or nonliteral relationship. What it means is that in a metaphor one idea it is substitute for a new one.

For example,

4. Creating Analogies Teachers can use analogies to show the students how two items that seems different can have something in common. If the students use this method, they can enhance their understanding if they find the correlation between two concepts.

Comments: Martha you did such a great job, and I love how you used the "Venn diagram." You are amazing in doing this wiki. Penny
