中文摘要：随着科学技术的进步，估算能力对每一位社会成员来说显得尤为重要，通过对三年级～八年级学生估算意识及策略的调查，发现学生对“估算”了解较少，估算意识与技能比较薄弱．主要体现在：（1）对“估算”这一概念的理解比较肤浅；（2）认为估算重要，但估算能力不强；（3）合理运用估算技能的意识较差；（4）估算经验较为有限；（5）估算策略具有多样性，与题型有关．

外文摘要：This study investigated 3～8 graders for their computational estimation consciousness. The following conclusions were obtained： Students＇ understanding of the computational estimation was comparatively little, and their consciousness and skill of the computational estimation was weak. It could be seen mainly as follows： （1） Their comprehension of the concept ＂computational estimation＂ was superficial. （2） Their knowledge of estimation methods and estimation results was poor. （3） Their consciousness and capability of using the skill of computational estimation were comparatively weak. （4） Their experience of computational estimation was limited. （5） The strategies of computational estimation are various. The students could choose the strategies flexibly when the estimation tasks were appropriate for them.
