英语翻译
Many elementary teachers have been found to have high levels of mathematics anxiety but the
impact on student achievement was unknown.Elementary teachers (N = 692) completed the
modified Mathematics Anxiety Rating Scale-Revised (Hopko,2003) along with a questionnaire
probing anxiety about teaching mathematics and current mathematics instructional practices.
Student mathematics achievement data were collected for the classrooms taught by the teachers.
A positive relationship was found between anxiety about mathematics and anxiety about teaching
mathematics.Increased student mathematics achievement was related to lower levels of anxiety
about teaching mathematics,but was not related to general anxiety about mathematics.Anxiety
about mathematics was positively related to more National Council of Teachers of Mathematics
(NCTM) Standards-based instructional practices.
许多小学教师已发现有高水平的数学焦虑,但对学生成绩的影响是未知的.小学教师(N = 692)完成了数学焦虑评定量表(Hopko,2003)的修改以及一个探讨数学教学和当前数学教学实践的焦虑的问卷调查.学生的数学成绩数据由授课教室的老师收集.数学焦虑和数学教学焦虑之间一个积极的关系被发现.学生数学成绩的提高降低了数学教学的焦虑水平,但与一般的数学焦虑无关.数学焦虑和更多的国家数学教师委员会（美国）基于标准的教学实践呈正相关.
