论文摘要
当前的研究采用网络分析方法来探索学生在新西兰Aotearoa的最后一年中所采取的STEM途径。通过从新西兰的集成数据基础架构访问个人级别的微型数据,我们能够创建一个由新西兰学生在2010年至2016年之间在新西兰学生所采取的所有STEM评估标准组成的共同吸收网络。我们探索了该共同培训网络的结构,尽管使用了社区检测和新颖的熵测量。然后,我们研究了基于学生的性别,种族和他们参加过的高中的社会经济地位(SES),网络结构如何在子人群之间有所不同。结果表明,茎共获得网络的结构在这些亚种群中有所不同,并且随着时间的流逝而变化。我们发现,尽管女学生更有可能纳入生命科学标准,但在物理,微积分和职业(例如农业,实用技术)标准方面,她们的代表性不佳。我们的结果还表明,毛利人和太平洋岛屿亚种群的入学模式具有较高的熵水平,这一观察结果可能通过关键科学和数学标准的入学率较少来解释。通过进一步调查这种差异,我们发现熵的种族差异受到高中SES的调节,使得毛利人和太平洋岛屿学生之间的熵差异以及欧洲和亚洲的学生更大。我们在2010年至2016年之间发生的新西兰教育体系和政策变化的背景下讨论了这些发现。
The current study uses a network analysis approach to explore the STEM pathways that students take through their final year of high school in Aotearoa New Zealand. By accessing individual-level microdata from New Zealand's Integrated Data Infrastructure, we are able to create a co-enrolment network comprised of all STEM assessment standards taken by students in New Zealand between 2010 and 2016. We explore the structure of this co-enrolment network though use of community detection and a novel measure of entropy. We then investigate how network structure differs across sub-populations based on students' sex, ethnicity, and the socio-economic-status (SES) of the high school they attended. Results show the structure of the STEM co-enrolment network differs across these sub-populations, and also changes over time. We find that, while female students were more likely to have been enrolled in life science standards, they were less well represented in physics, calculus, and vocational (e.g., agriculture, practical technology) standards. Our results also show that the enrolment patterns of the Maori and Pacific Islands sub-populations had higher levels of entropy, an observation that may be explained by fewer enrolments in key science and mathematics standards. Through further investigation of this disparity, we find that ethnic group differences in entropy are moderated by high school SES, such that the difference in entropy between Maori and Pacific Islands students, and European and Asian students is even greater. We discuss these findings in the context of the New Zealand education system and policy changes that occurred between 2010 and 2016.
