The purpose of this study was to develop a valid and reliable common content knowledge (CCK) instrument for pre-service teachers who teach fundamental tennis in secondary schools. The instrument, called the tennis CCK test for pre-service teachers (CCK-Tennis), was administered to 117 undergraduate students who were enrolled in physical education (PE) teacher education programmes at three universities in the United States. Two tennis content experts developed the CCK-Tennis and five in-service teachers reviewed the test to establish content validity. A total of 10 pre-service teachers took the test for pilot testing. The data were analysed using Rasch statistics (Linacre, 2011; Rasch, 1980). The authors judged the unidimensionality of the CCK-Tennis using the unexplained variance in the first contrast (2.59) and the standardized residual contrast one plot (-0.4 to 0.4). These data provided evidence that the test is unidimensional and measures tennis CCK. The results of infit (0.8 to 1.2) and outfit (0.5 to 1.5) mean square residuals showed that the difficulty of the questions matches respondents’ knowledge levels. The item (5.32, Cronbach’s α = 0.97) and person (1.71, Cronbach’s α = 0.72) separation index and the Wright map showed that there are low to high knowledge levels of the respondents who took the test. The results illustrate that the CCK-Tennis is a robust, valid, and reliable tool that people can use in teacher education. Having valid and reliable measures for CCK is an essential step to improve teachers’ instructional effectiveness from the area of content knowledge.

这项研究的目的是为在中学教授基础网球的职前教师开发一种有效且可靠的通用内容知识（CCK）仪器。该仪器被称为“职前教师网球CCK测试”（CCK-Tennis），已在美国三所大学的117名本科生中参加了体育（PE）教师教育计划。两名网球内容专家开发了CCK-Tennis，五名在职教师对测试进行了审查，以确定内容的有效性。共有10名职前教师参加了该测试以进行试点测试。使用Rasch统计数据分析数据（Linacre，2011年； Rasch，1980年）。作者使用第一对比中无法解释的方差来判断CCK-网球的一维性（2。59）和标准化残差对比图（-0.4至0.4）。这些数据提供了证明该测试是一维的并且可以测量网球CCK的证据。拟合（0.8至1.2）和服装（0.5至1.5）均方差的结果表明，问题的难度与受访者的知识水平相匹配。项目（5.32，克伦巴赫α = 0.97）和人（1.71，Cronbach的α = 0.72）分离指数和赖特地图显示，有低的谁考了受访者的高知识水平。结果表明，CCK-网球是人们可以在教师教育中使用的强大，有效和可靠的工具。采取有效和可靠的CCK措施是从内容知识领域提高教师教学效果的重要步骤。
