由于对位数值的误解,学生们经常与小数系统作斗争. 使用其他基础系统与数字工具帮助他们掌握多位数和熟悉的操作.
科学领域:
- 教育技术的教育技术
- 数学教育教育 数学教育
- 认知科学 认知科学
背景情况:
- 学生在十进制计数中的错误源于误解定位数字系统的结构.
- 数字工具可以说明和培训,或在有意义的活动中创建了解位置计数的环境.
- 活动方法被用来支学生的学习,并揭示多位数概念的起源.
研究的目的:
- 为学习多位数概念提供计算机支持方法.
- 使用这种方法讨论一系列初步培训的初步结果.
主要方法:
- 设计了一个基于计算机的教育模块",星际流浪者",基于学习活动理论.
- 利用其他基础系统鼓励学生重新评估基础十运算.
- 与20名学生 (2-5年级) 进行30小时的实验课程.
- 通过课堂观察,录像讨论和模拟日志收集数据.
主要成果:
- 初步发现表明,开发的计算机支持架构使学生对多位数概念的理解得到了改善.
- 学生们通过对十进制的反思性重新思考来表现进步.
- 需要进一步的研究来进行定量性绩效分析.
结论:
- 通过活动方法设计的计算机支持通过分析概念起源和学生的行为来帮助学习.
- 对于学习活动的数字工具有需求,并显示出有希望的结果.
- 这种方法支持通过反思获得多位数概念.
