This project aims to advance the preparation of preservice teachers in middle school mathematics, specifically on the topic of proportionality, a centrally important and difficult topic in middle school mathematics that is essential to students’ later success in algebra. To address the need for a workforce of high-quality teachers to teach this mathematics, the project is developing a digital text that could be widely used to communicate the unique transitional nature of middle school mathematics.
This project builds on prior efforts with learning progressions, and is focused on key carbon-transforming processes in socio-ecological systems at multiple scales, including cellular and organismal metabolism, ecosystem energetics and carbon cycling, carbon sequestration, and combustion of fossil fuels. The primary project outcomes will be coordinated instructional tools that are useful to professionals at all levels in the science education system--classroom teachers, professional developers, and developers of curricula, standards and assessments.
This project targets first- and second-grade children who struggle to develop a deeper understanding of the mathematical strand of number and operation. The research team will (a) identify the various specific cognitive obstacles of first- and second-grade students who are struggling in number and operation, and (b) explore how instructional tasks designed to address specific cognitive obstacles affect the learning trajectory of struggling learners in number and operation.
