How It Works

Decoding is word unlocking, a relatively low level cognitive process when compared to the complex task of reading, which must include meaning. It responds to stimulus response conditioning and can be developed successfully in a relatively short period of time.

Learn how to teach Glass-Analysis

Teachers use the Teacher Guide to familiarize themselves with the Glass-Analysis method, the kit tools, and how to structure instructional sessions.

Teach a decoding session using the Cluster Cards

Teachers use Cluster Cards to teach a decoding session using a question and answer format outlined in the Teacher Guide.

Practice decoding with your students

Teachers use the Follow Through Practice Books to transfer from the cards to oral at-sight reading at the end of each instructional session.

Decoding Program

A Behavioral Approach

In the Glass-Analysis approach, the immediate task is to match printed symbols to their appropriate sounds. Students then recognize the meaning that the printed word represents. The program offers immediate reinforcement and communicates to the learner which responses are effective and will be successful in decoding.

Learning A Process, Not A Word

Our purpose is not to teach the defınition of the word, as cluster card words are already in the students’ vocabulary. Students do not memorize rules and/or principles of language. They do not have to fıgure out whether vowels are long or short. Each cluster card is designed to condition the student to focus on the sight and sound of each word by assembling its clusters.
