Purpose

The authors demonstrate the usage of data visualization for conveying educational administration research, with a specific focus on differential principal turnover. They model when and how principals move, over time, between six categories of turnover.

Design/methodology/approach

The authors construct several easy-to-interpret alluvial diagrams that reveal the patterns of differential turnover among 1,113 first-time Texas principals. Furthermore, the authors investigate how these patterns differ across educator characteristics (i.e. race and sex) and school contexts (i.e. school level and campus urbanicity).

Findings

Half of all first-time principals turn over within two years. Most principals who stay in leadership roles leave the district where they were first entered the principalship. Men are promoted more and women turn over less. In a connected finding, the authors conclude that elementary principals turn over less, and middle and high school principals are promoted more often. Principals of color are demoted more often than White principals. Urban school principals exit the system at a greater rate than rural principals.

Originality/value

The significance of this study lies in its direct response to two problems facing the administrator turnover knowledge base – a lack of methodological accessibility and the underutilization of data visualization. The authors’ is the first study to contain visualization of differential turnover outcomes over time. Second, the authors’ study provides a blueprint for data visualization that not only creates new knowledge but also speaks to a wider variety of education stakeholders by presenting complex data in a visual format.

可视化差异本金周转率

目的

作者演示了数据可视化在传达教育管理研究中的用途，特别关注差异校长的流失。他们为校长在六类营业额之间随时间变化的方式和方式建模。

设计/方法/方法

作者构建了几个易于理解的冲积图，揭示了1113位德克萨斯州初任校长之间营业额差异的模式。此外，作者调查了这些模式在教育者特征（即种族和性别）和学校环境（即学校水平和校园城市化程度）之间的差异。

发现

首次校长中有一半是在两年内上任的。大多数担任领导职务的校长都会离开他们最初进入校长的地区。男性升职更多，女性流失更少。在一个相关的发现中，作者得出结论，小学校长的轮换较少，而初中和高中校长的升迁更为频繁。彩色校长比白人校长降级的频率更高。城镇学校校长退出系统的比率高于农村校长。

创意/价值

这项研究的意义在于对管理人员更替知识库所面临的两个问题的直接反应-缺乏方法上的可访问性和数据可视化的利用不足。作者的第一项研究包含了随着时间变化而产生的不同营业额结果的可视化。其次，作者的研究为数据可视化提供了一个蓝图，该蓝图不仅可以创造新知识，而且还可以通过以可视格式显示复杂数据来与更多的教育利益相关者交流。
