Semantic Feature Analysis

A graphic organizer, in the form of a grid, used to compare and contrast words and concepts 

Example:

Students use a Semantic Feature Analysis grid to explore chemical properties.  This modified version has students find an example and place it in the corresponding location on the grid. This culminating activity uses the knowledge built from the word wall, vocabulary notebook, and concept sort to explore chemical properties.

Purpose

To explicitly highlight similarities and differences between key words and concepts. To explore how ideas are related to one another. To see connections, make predictions, and master important concepts.

Procedure

1. Write key words down the left side and specific features across the top of the grid. (Some teachers write key words across the top and features down the left side of the grid.)
2. Display the grid and discuss the first word and features being analyzed with the class.
3. Mark the grid to reflect whether or not the key word has the given features.

Options:Write a  yes (or +)  if the feature is a characteristic of the term; no (or -) if the feature is not a characteristic; and a question mark if further investigation is needed.Check off only the features which pertain to the key word.Mark the grid with A=Always, S=Sometimes, and N= Never.Have students complete the grid individually or in small groups.

4. Discuss findings with the class. Discussion is a key element in the effectiveness of this strategy. Encourage students to discuss how they decided a certain feature applies to a word.

Modifications and extensions:

1. As students finish the chart, have them reflect on the relationships between the words by writing a paragraph in their vocabulary notebook.
2. Have students add new words to the grid during the unit to explore how these new words relate to already established key words and concepts.
