一个效度,各自表述

On Two Types of Validity

效度是反映测验质量的最重要的指标,效度研究贯穿测验始终,覆盖测验的方方面面。测验的效度与测验的用途密切相关,没有无关测验用途的效度研究。效度研究是基于经验判断基础之上的,这里的经验判断,即效度研究中所需的假设。效度研究具有相对性,同时又要强调其可操作性。效度研究人员不仅要提供可靠、值得信赖的研究结果,而且要通过效度研究促进测验制度和文化的发展。

As an important index to guarantee the quality of a test, validity is supposed to be a comprehensive and applicability-oriented action, as well as an overall one to cover the whole length.Studies of validity are normally based on rationality, which can be the hypothesis needed for further detailed research. From this perspective, validity research appeals to the researchers and practitioners for relativity and maneuverability. In this case, validity researches are supposed to offer reliable databased findings for both content validity and construct validity, so as to promote the development of ex amination system and culture as well.
