Developing the Conceptual Underpinnings of Evolution in Second and Third Grade

项目摘要：本实证研究将学习进阶视角应用于进化论教学，为二年级和三年级学生提供了进化论概念基础的初步进展。进化的中心地位使其成为战略性长期连贯知识建设的主要目标。两种课程模式？一个是动物行为学，一个是植物学？支持学习进程。这些模块建立在pi之上？以前的工作，脚手架小学一年级的孩子？在这些领域进行科学探究。研究小组在两种地点研究课程制定和学生学习，(1)一个项目运行的夏季充实计划，(2)市内公立学校的教室。

DRL-0814821PI: Kathleen Metz PROJECT ABSTRACTThis empirical study applies the learning progression perspective to the teaching of evolution, posting an initial progression for the conceptual underpinnings of evolution for second and third graders. The centrality of evolution makes it a prime target for strategic long-term coherent knowledge-building. Two curriculum models?one in animal behavior and one in botany?support the learning progressions. These modules build on the PIs? prior work, scaffolding primary grade children?s scientific inquiry in these domains. The research team studies the curricular enactment and student learning in two kinds of sites, (1) a project-run summer enrichment program, and (2) inner-city public school classrooms.
