Knowing a word means knowing its pronunciation, spelling, concept area, and meaning layers. Vocabulary is never an area that can be learned completely by individuals; rather it is a field that expands and deepens throughout life. Vocabulary teaching requires much more than just looking up words in a dictionary or using them in a sentence.…

We show how the novel use of a semantic representation based on Osgood's semantic differential scales can lead to effective features in predicting short- and long-term learning in students using a vocabulary learning system. Previous studies in students' intermediate knowledge states during vocabulary acquisition did not provide much information…

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word's…

Adolescents often use root word and affix knowledge to figure out unknown words. Anglin (1993) found that younger readers favor the Part-to-Whole strategy, and Tyler and Nagy (1989) confirmed the importance of root-word knowledge for middle school students. This study seeks to understand the different strategies middle school readers use so that…

The current study uses a crossed random-effects item response model to simultaneously examine both reader and word characteristics and interactions between them that predict the reading of 39 morphologically complex words for 221 middle school students. Results suggest that a reader's ability to read a root word (e.g., "isolate") predicts that…

This facilitator's guide is designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. Through this collaborative learning experience, educators will expand their knowledge base as they read, discuss, share,…

These handouts, which are meant to accompany the facilitator's guide, are designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. The facilitator's guide uses a five-step process for collaborative…

Word Links, an effective strategy for developing students' vocabulary, is based on four principles. It provides contextual and definitional information; offers repeated exposure to words and opportunities to practice them; encourages students to think about relationships among word meanings; and involves active engagement in learning tasks. Yopp…
