9553902 diSessa This project will investigate the strengths and limitations of students' meta-representational competence-that is, thier knowledge about representing scientific concepts and phenomena in a pictorial form. Foci will include student capability to: (a) design new representations;(b) to critique, compare and refine them;(c) to select appropriate ones and learn to use them efficiently; and (d) to understand what represents are for and how they work. The project will investigate the relation of meta-representational competence to conceptual development and will also design and research classroom instructional activities that effectively utilize and develop meta-representational competence. Results will help teachers better understand students' strengths and weakness in learning representations in mathematics and science, and will open up an attractive new genre of authentic scientific learning activities that can involve students have a wide range of intellectual styles and abilities. ***

9553902 diSessa 该项目将调查学生元表征能力的优势和局限性，即他们以图形形式表征科学概念和现象的知识。重点将包括学生以下能力：(a) 设计新的表示；(b) 批判、比较和完善它们；(c) 选择合适的表示并学习有效地使用它们； (d) 了解代表的用途及其工作原理。 该项目将调查元表征能力与概念发展的关系，并将设计和研究有效利用和发展元表征能力的课堂教学活动。 研究结果将帮助教师更好地了解学生在学习数学和科学表征方面的优势和劣势，并将开辟一种有吸引力的新类型的真实科学学习活动，让具有广泛智力风格和能力的学生参与其中。 ***
