Seeds of Science / Roots of Reading: Developing a New Generation of Research-based Elementary Science Instructional Materials

“科学的种子/阅读的根源：开发新一代以研究为基础的基本科学教学材料”将为三至四年级开发和测试三个以探究为基础的科学单元--生命科学、地球科学和物理科学各一个。 种子/根系列是一个综合的科学素养教学计划的基础上成功的NSF资助的概念验证倡议。 种子/根建立在数学和科学（GEMS）计划的伟大探索单元的修订;但更新和采用了一种新的，多模式的“做它，说它，读它，写它”学习模式，在科学探究服务中使用识字。 该学习模式利用科学和识字之间的自然协同作用，使两个领域受益，并强调对英语学习者的支持。 通过其他资金来源，该提案将利用NSF在该计划中的初始投资，并在其成功的基础上实现整个2-5级计划的商业化。 该项目还将为整个系列开发一个在线指南，并为管理人员和父母/照顾者提供材料。

"Seeds of Science/Roots of Reading: Developing a New Generation of Research-based Elementary Science Instructional Materials" will develop and test three inquiry-based science units for 3rd-4th grades -- one each in life, earth and physical science. The Seeds/Roots series is an integrated science-literacy instructional program based on a successful NSF-funded proof-of-concept initiative. Seeds/Roots builds on revision of units in the Great Explorations in Math and Science (GEMS) Program; but updates and employs a new, multi-modal "Do it, talk it, read it, write it" learning model, with literacy used in the service of science inquiry. The learning model capitalizes on natural synergies between science and literacy to the benefit of both domains, and emphasizes support for English Language Learners. With other funding sources this proposal will leverage NSF's initial investment in this program and build on its success to enable the commercial launch of the entire grades 2-5 program. The project will also develop an online guide to the entire series as well as materials for administrators and parents/caregivers.
