The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller…

In May 2023, the Civil Rights Division (the Division) of the U.S. Department of Justice and the Office for Civil Rights (OCR) at the U.S. Department of Education jointly released this Resource on Confronting Racial Discrimination in Student Discipline. The Resource demonstrates the departments' ongoing commitment to the vigorous enforcement of…

This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration,…

Statistics has been a content domain in the mathematics curriculum for decades. However, statistics is a distinct discipline from mathematics and there are important differences in how one should teach the two disciplines. In this article, the authors consider how these differences can inform an adaptation to the 5 Practices for Orchestrating…

The ideal gas law, "PV = nRT," is one of the simplest physical laws in nature that is introduced to students as early as in high school and first year in college. In this equation, "P" stands for pressure, "V" is the volume, "n" is the amount expressed in mole, "T" is the temperature in Kelvin…

Within physics education research (PER), inductive teaching strategies (e.g., inquiry-based teaching) have long been a goal. Yet others do not seem to be convinced that consensus exists with respect to the goals of physics education and identify three possible goals as: (1) to teach practical, factual knowledge, (2) to develop deep understandings…

This article identifies and unpacks three key decision points in a systematic mixed research synthesis, a mixed methods approach to research synthesis. The research community has increasingly recognized the value of synthesis studies in expanding our understanding of phenomena. Mixed-methodology broadly has also gained ground as a pragmatic…

This is an article about abstraction, generalization, and the beauty of mathematics. We claim that abstraction and generalization in of itself may very well be a beauty of the human mind. The fact that we humans continue to explore and expand mathematics is truly beautiful and remarkable. Many years ago, our ancestors understood that seven stones,…

In accordance with the Government Performance and Results Modernization Act of 2010, this report provides a summary of the U.S. Department of Education (Department) Office of Inspector General (OIG) performance highlights and results of their performance measures for fiscal year (FY) 2021. Those goals align with OIG's FYs 2018-2022 Strategic Plan…

This paper presents the best practices used by institutional review boards (IRBs) and human research protections programs (HRPPs) to prepare online graduate student investigators for human research protections specific to research within online graduate degree programs or where research supervisors are not proximal to graduate student…

In this article, Robin Conway and Amy Scott show how they made use of online source archives to replicate the experience of an academic historian in the classroom. By changing the way that students approach sources, moving away from both 'fun activities' and formulaic exam preparation towards a more authentic experience, they show how students'…

This article offers two novel tools for teaching political science methodology and research design. The first is a comprehensive framework for helping students conceptualize a research project in political science. The second is a reformulation of the dominant conceptualization of process-tracing tests. Building on Collier's use of Sherlock Holmes…

In accordance with the Government Performance and Results Modernization Act of 2010, this U.S. Department of Education (Department) Office of Inspector General (OIG) Fiscal Year 2020 Performance Results Report presents the results of OIG's work over fiscal year (FY) 2020 in meeting their performance measures goals. Those goals align with OIG's FYs…

The COVID-19 pandemic affected the ways in which school districts provide educational services to all students, especially students with disabilities. Eligible U.S. students with disabilities have a right to a free, appropriate public education (FAPE) under the Individuals with Disabilities Education Act (IDEA), and students with disabilities who…

This sixth-form chemistry activity describes how students can use acid-base titrimetry to investigate how adding salt to the aqueous phase may change the value of the partition coefficient of an organic acid between water and 2-methylpropan-1-ol. While the presence of lithium chloride and sodium chloride increases the value of the partition…
