基于E–Prime的职前小学教师口算素养测评研究

Using E-Prime to Evaluate Teachers’ Proficiency of Mental Arithmetics in Elementary School

口算素养反映了小学教师思维敏捷程度、运算知识和能力的高低,是小学教师无关学科背景的必备素养,因此有效测评职前小学教师口算素养对于提高小学教师培养质量,促进职前小学教师专业发展都具有重要的意义和价值.选取不同专业方向的职前小学教师为研究对象,基于S-O-R理论模型,利用计算机化行为研究的E-Prime软件,设计了职前小学教师口算素养的测试程序和实验过程,探究职前小学教师口算素养的现状和影响因素.研究发现:职前小学教师口算素养整体水平有待于进一步提高;职前小学教师口算素养存在个体差异、群体差异;中学数学成绩是影响职前小学教师口算素养水平的重要因素.研究建议:培养口算素养应该成为小学教师教育数学课程改革的重要目标和内容;需要探索建立包含口算素养测试在内的小学教师数学素养测试制度.

Verbal calculation proficiency is a necessary mathematical literacy of primary school teachers. It is an indicator of the agility of thinking, calculation knowledge, and ability of teachers. An effective evaluation of verbal calculation literacy is very significant for promoting pre-service teachers’ mathematics literacy in primary school. This study selected pre-service primary school teachers who taught different courses. Based on the S-O-R theoretical model, we designed a process of evaluation and experiment to investigate primary school teachers’ verbal calculation proficiency and its influencing factors based on E-Prime software, which is used to study learners’ computerized behavior. Three findings are: Pre-service primary school teachers had a low verbal calculation proficiency;there were several differences in the verbal calculation proficiency among different pre-service teachers and different groups;and the mathematical achievement of the pre-service teachers was an important factor affecting their verbal calculation proficiency. We end with two suggestions from this study:(1) Verbal calculation proficiency should be an important goal of mathematics curriculum reform to develop teachers’ professional proficiency, and(2) the field of mathematics education should consider establishing a system to evaluate teachers’ mathematics literacies, including their verbal calculation proficiency.
