Calculators and Mathematics Project - Los Angeles (CAMP-LA)

电子手持计算器是小学数学课程中不可或缺的工具。由于计算器如此丰富和便宜，每个孩子都应该有一个计算器，以便在数学和其他可以应用数学的学科中适当地使用。虽然有一些材料支持在小学使用计算器，但目前还没有一套连贯的材料以新的视角看待课程，认为计算器是学习和做数学所必需的工具。这个项目将开发一个改变K-6数学课程的模型，基于每个孩子都有计算器的假设。预期的变化包括减少花在某些主题上的时间(如长除法)，增加花在其他主题上的时间(如解决问题和推理)。该项目将为K-6年级编写一套使用计算机的学生材料，设计得足够灵活，可以独立或作为补充；一套教师材料，其中将包括使用计算机教授数学的指南和学生评估材料，以及在从事诸如解决问题等活动时评估学生工作的协议；以及关于在初级环境中使用计算器的材料，用于教师的职前准备。该项目将由加州州立大学富勒顿分校和洛杉矶联合学区共同努力。该项目的目标之一是为大学-学区在课程开发和教师教育方面的合作创造一个可复制的模式。

The electronic hand-held calculator is a tool that can be used as an integral part of the elementary school mathematics curriculum. With calculators so abundant and inexpensive, each child should be able to have a calculator for appropriate use in mathematics and in other subjects where mathematics can be applied. Although some materials are available that support the use of the calculator in the elementary school, there exists currently no coherent set of materials that looks at the curriculum in a new light, assuming that the calculator is an essential tool to be used in learning and doing mathematics. This project will develop a model for change in the K-6 mathematics curriculum, based on the assumption that every child has a calculator. Anticipated changes include diminishing time spent on certain topics (such as long division) and increasing time spent on other topics (such as problem solving and reasoning). The project will develop a set of calculator-based student materials for Grades K-6 designed to be flexible enough to stand alone or be supplementary; a set of teacher materials that will include a guide for teaching mathematics using calculators and student evaluation materials with protocols for evaluating student work when engaged in activities such as problem solving; and materials on the use of calculators in an elementary setting, to be used in the preservice preparation of teachers. The project will be a collaborative effort of the California State University at Fulleraton and the Los Angeles Unified School District. One of the goals of the project is to create a replicable model for university-school district cooperation in curriculum development and teacher education.
