This article develops new closed-form variance expressions for power analyses for commonly used difference-in-differences (DID) and comparative interrupted time series (CITS) panel data estimators. The main contribution is to incorporate variation in treatment timing into the analysis. The power formulas also account for other key design features…

This activity challenges students to establish media usage rules for a 30-day digital declutter, during which time they challenge themselves to disengage from distracting digital media. Students write self-assessments about their media habits and relationship to media before beginning the declutter and after they have finished the 30-day…

In addition to the third edition of EUA's Autonomy Scorecard, which was published in March 2023, a series of country profiles were released between Autumn 2023 and Spring 2024. The comprehensive analysis of all indicators in these systems revealed that in some cases there was a need for a different categorisation of specific situations. While the…

The first round of data from the Integrated Postsecondary Education Data System's (IPEDS) newest survey component, Outcome Measures (OM), was released to the public in Fall 2017. Importantly, the IPEDS OM survey begins to address some of the limitations of the prevailing Graduation Rate (GR) component data. These rates have only included…

In recent years, machine translation post-editing (MTPE or PE for short) has been steadily gaining ground in the language industry. However, studies that examine translators' perceptions of, and attitudes towards, MTPE paint a somewhat negative picture, with PE pricing methods and rates being a major source of dissatisfaction. While the European…

International large-scale assessments (ILSAs) transitioned from paper-based assessments to computer-based assessments (CBAs) facilitating the use of new item types and more effective data collection tools. This allows implementation of more complex test designs and to collect process and response time (RT) data. These new data types can be used to…

Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study. [For "The Data Files: A Series of Articles to Support Mathematics Teachers to Teach Statistics," see EJ1259108.]

Short comparative interrupted times series (CITS) designs are increasingly being used in education research to assess the effectiveness of school-level interventions. These designs can be implemented relatively inexpensively, often drawing on publicly available data on aggregate school performance. However, the validity of this approach hinges on…

This paper discusses the contrasting perspectives of academic prose versus grant writing, and lists strategies grant specialists can use to help researchers break old habits and replace them with techniques better suited to the world of competitive grant proposals. [This article is a reprint of "Why Academics Have a Hard Time Writing Good…

The metrics used in the US to track students do not include adults and part-time students. This has led to the development of a massive data initiative--the Predictive Analytics Reporting (PAR) framework--that uses predictive analytics to trace the progress of all types of students in the system. This development has allowed actionable,…

In this brief, the authors propose three measures of "early momentum" for two reasons: Research is beginning to show that these near-term metrics predict long-term success, and the metrics focus attention on initial conditions at colleges that are particularly important for solidifying the foundation for student success. While these…

This review protocol from the What Works Clearinghouse (WWC) covers the following issues relevant to screening criteria and full review for the Access to Higher Education Practice Guide: (1) time frame; (2) study design; (3) age and/or grade range; (4) brief description of intervention; (5) key subgroups; (6) location and language; (7) outcomes…

The purpose of this article is to describe the construction of a Sun clock and calendar (SCandC) that will allow an observer to not only see the time but also the symmetry properties of the Sun-Earth relative movement. A set of circles drawn on the SCandC will allow the observer to see their associated dates as well as to perform a visual…

It is no accident that the first use of computers in school systems was to arrange schedules for students and teachers. The proper use of the computer in the classroom is as a replacement for the clock and its strict temporal schedule. By conveying information through self-instructional content, the computer can schedule work for pupils in…

The report provides an overview of Aboriginal learners (First Nations, Inuit, and Métis peoples) in British Columbia, Canada. Section 1 examines the data on transitions from K-12 to the post-secondary system. Section 2 discusses recent trends in the B.C. public post-secondary system including headcount, full-time equivalents and credentials.…
