Math Snacks: Addressing Gaps in Conceptual Mathematics Understanding with Innovative Media

DRL：DR K-12PI：WiburgAbstra该项目由新墨西哥州立大学的数学和教育系领导，该项目名为《数学小吃：用创新媒体解决概念数学理解中的差距》，该项目正在开发和评估15-20个简短的计算机动画和游戏的有效性，这些动画和游戏旨在：(1)增加学生？(2)提高学生的数学过程技能，重点是数学思维和数学对话的能力。该项目的基本研究问题是，计划中的计算机动画和游戏集合是否可以提供一种有效的策略，帮助那些在中学数学核心概念上遇到困难的学生，以及这些材料是否可以作为普通课堂教学的有用工具。该项目正在开发和测试一套广泛的此类学习工具、帮助学习者发展概念理解所需的配套印刷材料，以及记录模范教师与学生使用所开发材料的最佳实践的短视频剪辑的有效性。三年级的一项试点研究和四年级的一项大规模随机对照试验正在测试使用数学零食软件对学生学习和保持中学数学的影响，这是通过新墨西哥州数学评估的分解部分的表现来衡量的。因此，该项目将产生软件小程序、教师材料和关于它们使用效果的有用的经验证据。数学零食项目的关键特征之一是开发中介游戏和模拟，其形式可以由学生在普通课堂之外的媒体和游戏机上使用，这些媒体和游戏机在当今年轻人中无处不在并很受欢迎。因此，该项目有望利用非正式环境中的学习来改善传统的学校体验。

DRL: DR K-12PI: WiburgAbstractThis project Math Snacks: Addressing Gaps in Conceptual Mathematics Understanding with Innovative Media, led by mathematics and education faculty at New Mexico State University, is developing and evaluating effectiveness of 15 - 20 short computer mediated animations and games that are designed to: (1) increase students? conceptual understanding in especially problematic topics of middle grades mathematics; and (2) increase students' mathematics process skills with a focus on capabilities to think and talk mathematically. The basic research question of the project is whether the planned collection of computer-mediated animations and games can provide an effective strategy for helping students who experience difficulty with core middle grades mathematics concepts and whether the same material can be a useful tool for ordinary classroom instruction. The project is developing and testing the effectiveness of an extensive set of such learning tools, companion print materials as needed to assist learners in developing conceptual understanding, and short video clips documenting best practices by exemplary teachers using the developed materials with students.A pilot study in year 3 and a substantial randomized control trial in year 4 are testing the effects of using the Math Snacks software on student learning and retention of middle school mathematics, as measured by performance on disaggregated strands of New Mexico state mathematics assessments. Thus the project will produce software applets, teacher materials, and useful empirical evidence about the efficacy of their use.One of the key features of the Math Snacks project is development of the mediated games and simulations in a form that can be used by students outside of normal classroom settings on media and game players that are ubiquitous and popular among today's young people. Thus the project holds the promise of exploiting learning in informal settings to enhance traditional school experiences.
