City College of New York (CUNY) is conducting a 3-year exploratory project to develop and test curricular resources built around handheld mobile technology to study how these materials foster urban middle school student interest and engagement with local biodiversity and the patterns of evolution. Using Leafsnap, an iPhone application, the project allows students to use pattern recognition software to readily identify various species of plants. The project aims to develop curricular resources for middle school students built around the Leafsnap app through a co-design process; to pilot test curricular resources in the classrooms of three New York middle school teachers; to develop and revise assessment tools to measure student outcomes; and to field-test curricular resources in the classrooms of ten New York middle school teachers and analyze results to determine how the Leafsnap app affects urban middle school student learning of biodiversity and the patterns of evolution. The results will be used to modify curriculum and disseminate it online with the Leafsnap app.During the project's first year, the curricular resources in two middle schools in East Harlem will be used. In the second year, the resources will be used in the classrooms of ten New York City (NYC) public middle school teachers. In the third year, these resources will be integrated into a life science for middle school teachers course as part of CUNY's graduate program in secondary science education, a program specifically designed to prepare teacher candidates for careers in NYC public middle schools. Also, in the project's third year, the curricular resources will be disseminated through the Leafsnap website to a wider online audience.The project advances understanding of underrepresented urban middle school student learning of local biodiversity in a historical evolutionary context by addressing the three major dimensions of the new Framework for K-12 Science Learning: core science content, the practice of science, and concepts that crosscut all scientific disciplines. Pre- and post-treatment clinical interviews with students will be conducted to provide qualitative insights into how use of the Leafsnap curriculum impacts students' understanding and motivation for identifying and organizing tree diversity.

纽约城市学院 (CUNY) 正在进行一项为期 3 年的探索性项目，旨在开发和测试围绕手持移动技术构建的课程资源，以研究这些材料如何培养城市中学生的兴趣以及对当地生物多样性和进化模式的参与。该项目使用 iPhone 应用程序 Leafsnap，允许学生使用模式识别软件轻松识别各种植物。该项目旨在通过共同设计流程，围绕 Leafsnap 应用程序为中学生开发课程资源；在纽约三名中学教师的课堂上试行测试课程资源；开发和修改评估工具来衡量学生的成绩；在十名纽约中学教师的课堂上对课程资源进行实地测试，并分析结果，以确定 Leafsnap 应用程序如何影响城市中学生对生物多样性和进化模式的学习。结果将用于修改课程并通过 Leafsnap 应用程序在线传播。在该项目的第一年，将使用东哈莱姆区两所中学的课程资源。第二年，这些资源将用于十名纽约市 (NYC) 公立中学教师的课堂。第三年，这些资源将被纳入中学教师生命科学课程，作为纽约市立大学中等科学教育研究生项目的一部分，该项目专门为纽约市公立中学的教师候选人做好职业准备。此外，在该项目的第三年，课程资源将通过 Leafsnap 网站传播给更广泛的在线受众。该项目通过解决新的 K-12 科学学习框架的三个主要维度：核心科学内容、科学实践以及横贯所有科学学科的概念，增进对历史演化背景下代表性不足的城市中学生对当地生物多样性学习的理解。将在治疗前和治疗后对学生进行临床访谈，以定性地了解 Leafsnap 课程的使用如何影响学生识别和组织树木多样性的理解和动机。
