The purpose of this research was to validate the assessing interest in STEM content scale. The sample in this research was 552 students in upper secondary school at Fangchanupathum School, Chiang Mai, Thailand, who validated the assessing interest in STEM content scale, which used a rating scale of four factors consisting of (1) science, (2) mathematics, (3) laboratorial skills, and (4) technology and 20 items. Confirmatory factor analysis was used to confirm the construct validity of the assessing interest in STEM content scale adapted from the study by Tyler-Wood, Knezek, and Christensen. The results confirmed that the construct validity of this assessing interest in STEM content scale had an excellent fit. They showed that the fitness index of validating the assessing interest in STEM content scale was X2 statistic of 163.679 (degree of freedom = 141, value = 0.0928) and the X2/df ratio having a value of 1.160 indicating a good fit. The comparative fit index (CFI) was 0.991, and Tucker–Lewis coefficient (TLI) was 0.988. The root mean square error approximation (RMSEA) was 0.017. The standardized root mean residual (SRMR) was 0.047. All the indicators indicated that there was a good fit between the empirical data and the hypothetical measurement model.

在STEM内容量表中构建兴趣评估的有效性

这项研究的目的是验证对STEM内容量表的评估兴趣。这项研究的样本来自泰国清迈Fangchanupathum学校高中的552名学生，他们验证了对STEM内容量表的评估兴趣，该量表使用了四个因素，包括（1）科学，（2）数学，（3）实验技能和（4）技术和20个项目。验证性因子分析用于确定STEM含量量表的评估兴趣的构建效度，该量度由Tyler-Wood，Knezek和Christensen的研究改编而成。结果证实，该评估兴趣在STEM内容量表中的构建效度非常适合。他们显示，验证STEM内容量表中的评估兴趣的适合度指数是163的X2统计量。679（自由度= 141，值= 0.0928），并且X2 / df比值为1.160，表明拟合效果良好。比较拟合指数（CFI）为0.991，塔克-刘易斯系数（TLI）为0.988。均方根误差近似值（RMSEA）为0.017。标准化均方根残差（SRMR）为0.047。所有指标均表明，经验数据与假设的计量模型之间具有很好的拟合度。
