Raz-Kids, an award-winning teaching product, supports teachers in choosing high-quality, appropriately complex texts for students using a three-part model: quantitative measures, qualitative measures, and reader and task considerations.
Let’s delve into the details:
Quantitative Measures:
These include aspects such as sentence length, word length, word frequency, and repetition, best measured by computer software. Learning A-Z uses the Lexile Framework for Reading*, developed by MetaMetrics, Inc., for quantitative measurement of texts in English and Spanish.Qualitative Measures:
These are text attributes best evaluated by a human reader, including the author's purpose, levels of meaning, text structure, language conventions, language clarity, knowledge demands, and the complexity and importance of visual devices. Multiple trained subject matter experts at Learning A-Z evaluate the complexity of each text, represented as a Learning A-Z Level, aa–Z2.Reader and Task Considerations:
Each reader brings unique skills, background, and motivation to reading. Teachers should evaluate reader and task considerations based on each student's circumstances and their interaction with a specific book. By combining Lexile Measures and qualitative measures, teachers can make informed decisions about appropriate texts for the reader and task.
