Teaching science as a language: A “content‐first” approach to science teaching

Our research project was guided by the assumption that students who learn to understand phenomena in everyday terms prior to being taught scientific language will develop improved understanding of new concepts. We used web‐based software to teach students using a “content‐first” approach that allowed students to transition from everyday understanding of phenomena to the use of scientific language. This study involved 49 minority students who were randomly assigned into two groups for analysis: a treatment group (taught with everyday language prior to using scientific language) and a control group (taught with scientific language). Using a pre–post‐test control group design, we assessed students' conceptual and linguistic understanding of photosynthesis. The results of this study indicated that students taught with the “content‐first” approach developed significantly improved understanding when compared to students taught in traditional ways. © 2008 Wiley Periodicals, Inc.

Creating contextually authentic science in a “low‐performing” urban elementary school

This article reports on a 2½‐year collaborate project to reform the teaching and learning of science in the context of Mae Jemison Elementary, the lowest performing elementary school in the state of Louisiana. I outline a taxonomy of authentic science inquiry experiences and then use the resulting framework to focus on how project participants interpreted and enacted ideas about collaboration and authenticity. The resulting contextually authentic science inquiry model links the strengths of a canonically authentic model of science inquiry (grounded in the Western scientific canon) with the strengths of a youth‐centered model of authenticity (grounded in student‐generated inquiry), thus bringing together relevant content standards and topics with critical social relevance. I address the question of how such enactments may or may not promote doing science together and consider the implications of this model for urban science education. © 2006 Wiley Periodicals, Inc.
