2014 年 9 月 4 日，我国正式发布实施新高考“6 选 3”模式。2018 年，确定了河北、湖北、湖南、辽宁、江苏、福建、广东、重庆等 8 省市正式启动高考改革。新高考改革方案，推动了中学生生涯教育的提前发展，更促进了科学指导学生进行选科的需求，由此，本研究以兴趣探索的角度切入，进行高中生学科兴趣问卷的编制，并检验其在高中生群体中的信度和效度，从而为中学生进行“6 选 3”提供参考。
       根据总结以往研究中的文献内容和对高中生进行开放式问卷调查的结果，初步确定学科兴趣问卷的基本测量内容，形成初始题项。以高一年级学生作为研究对象，共对问卷进行两轮施测，第一次施测回收有效问卷 589 份，该部分数据用于项目分析和探索性因素分析，以进行题目的删改和修订；第二次施测回收有效问卷 1598 份，该部分数据用于验证性因素分析、外部效标效度检验和信度检验，并再次根据题目质量进行筛选，检验问卷的信度与效度。
      最后形成了正式的“6 选 3”学科兴趣问卷，该问卷包含 6 个学科兴趣分量表，分别对应“6 选 3”的指定选考科目。其中物理兴趣、政治兴趣、历史兴趣和地理兴趣分量表各包含 2 个维度，分别是情感卷入/锲而不舍和行动关注；化学兴趣和生物兴趣各包含 3 个维度，分别是情感卷入、行动关注和锲而不舍。经检验，学科兴趣问卷的拟合程度良好，Cronbach's α 系数为 0.94；各学科兴趣分量表的拟合程度良好，Cronbach's α 系数均在0.90 以上。而高中生各科学科兴趣与其对应的学科学习效能感、学业成绩之间均呈显著的正相关关系，并对高中生的兴趣特点进行一般分析，以检验学科兴趣问卷在实际中应用的结果。
       综上所述，高中生“6 选 3”学科兴趣问卷具有良好的信效度，可以从兴趣探索角度为高中生群体的“6 选 3”工作提供参考。

China officially announced the implementation of the new college entrance examination plan in 2014. Then, eight provinces and cities including Hebei, Liaoning, Jiangsu, Fujian, Hubei, Hunan, Guangdong and Chongqing were designated to launch the reform of college entrance examination in 2018. This reform promotes the advance development of career education of middle school students, and also promotes the demand of scientific guidance for students to select subjects. Therefore, the study start from the perspective of interest exploration, develop the Subject Interest Questionnaire for senior high school students under the background of the new college entrance examination, and test its reliability and validity, so as to provide reference for "6 choose 3" for middle school students.

According to the summary of the literature in previous studies and the results of an open questionnaire survey on high school students, determine the basic measurement content of the subject interest questionnaire and form the initial items. Then, the study was conducted in two rounds among the senior high school students. Item analysis and exploratory factor analysis was performed with the first sample (n=589). Then, confirmatory factor, external validity and reliability test was performed analysis with the second sample (n=1598).

Finally, Senior High School Students' Subject Interest Questionnaire was formed. The questionnaire contains six subscales of subject interest, corresponding to the designated subjects. The subscales of Physical interest, Political interest, Historical interest and Geographical interest contain two dimensions respectively, which are emotional involvement/perseverance and action concern. And Chemical interest and Biological interest contain three dimensions respectively, which are emotional involvement, action concern and perseverance. Through the test, the fitting degree of the subject interest questionnaire and each subject interest subscale was good, and the Cronbach α of the total scale was 0.95,each scale were above 0.90.

The questionnaire is appropriate for the evaluation of related research with acceptable reliability and validity and it can provide support for high school students to meet the challenges of college entrance examination reform.
