解析
【金标尺解析】本题考查教师教学工作的基本环节——衡量测验质量的指标。
效度是指测量的正确性,即一个测验能够测量出其所要测量的东西的程度,也就是我们常说的准确度。题干描述开学考试成绩能够预测入学学后的学业成绩表示开学考试测量出学生的真实学习水平。故A项符合题意。
B项:信度是指测验结果的稳定性或可靠性,即某一测验在多次进行后所得到的分数的稳定、一致程度。不符合题意,故排除。
C项:区分度是指测验对考生的不同水平能够区分的程度,即具有区分不同水平考生的能力。如,一次测验之后,能够明确分清不同学生的水平,我们就认为该测验的区分度较高。不符合题意,故排除。
D项:难度是指测验包含的试题难易程度。不符合题意,故排除。
故本题答案为A。
