This column provides ideas and techniques to enhance your science teaching. This month's issue discusses planning and using interactive word walls to support science and reading instruction. Many classrooms have word walls displaying vocabulary that students have learned in class. Word walls serve as visual scaffolds to support instruction. To support vocabulary development in science, we replaced traditional word walls, which are generally lists of words or word banks, with interactive word walls. Interactive word walls may resemble graphic organizers or data tables. They highlight connections between concepts and artifacts (realia) from inquiry-based science activities while connecting scientific concepts and academic vocabulary. They strategically target vocabulary and include visual aids that illustrate word meanings to deepen understanding. Interactive word walls usually include a visual representation of specific vocabulary words and labels. Definitions are optional. In this article, the authors describe how they select vocabulary for interactive word walls and their efforts to use interactive word walls as scaffolds that help students effectively communicate scientific ideas and structure writing.
