ROLE: Teaching Strategies to Promote the Construction of Science Understanding in Urban Schools

这项工作的目标是确定和发展教学实践，使城市非洲裔美国学生--世卫组织历史上没有达到高水平的学生--能够达到科学教育标准。对于这个项目，我们将教学实践定义为抽象科学概念的脚手架和内容表示。脚手架包括建模思维、组织和排序任务等策略，例如数据分析，以便学习者能够对这些工作负责(Collins，Brown和Newman；)。抽象科学概念的内容表示将包括实例、隐喻和行为，以帮助学生学习科学建模和因果关系等概念。

tHE GOAL OF THIS WORK IS TO IDENTIFY AND DEVELOP INSTRUCTIONAL PRACTICES SO THAT URBAN AFRICAN AMERICAN STUDENTS, WHO HISTORICALLY HAVE NOT ACHIEVED AT HIGH LEVELS, CAN MEET SCIENCE EDUCATION STANDARDS. FOR THIS PROJECT, WE DEFINE INSTRUCTIONAL PRACTICES AS SCAFFOLDS AND CONTENT REPRESENTATIONS OF ABSTRACT SCIENTIFIC IDEAS. SCAFFOLDS INCLUDE STRATEGIES LIKE MODELING THINKING, STRUCTURING AND SEQUENCING TASKS, SUCH AS DATA ANALYSIS, SO THAT LEARNERS CAN EVENTUAOLLY TAKE RESPONSIBILITIY FOR THIE WORK (COLLINS, BROWN AND NEWMAN; 1989). CONTENT REPRESENTATION OF ABSTRACT SCIENTIFIC IDEAS WILL INCLUDE EXAMPLES, METAPHORS, AND ACTIVIEIS TO HELP STUDENTS LEARN IDEAS SUCH AS SCIENTIFIC MODELING AND CAUSE AND EFFECT RELATIONSHIP.
