Gas Turbine Engines (GTE) have the highest power-to-weight ratio among Internal Combustion Engines (ICE). Its modularity and ability to utilize various types of fuel make it highly recommended in power plants, naval transportation, and, of course, the most equipped in aviation. The lack of GTEs' real data is increasing a recognized need for…

In his focus article, "Rethinking Traditional Methods of Survey Validation," published in this issue of "Measurement: Interdisciplinary Research and Perspectives," Andrew Maul wrote that it is commonly believed that self-report, survey-based instruments can be used to measure a wide range of psychological attributes, such as…

Independent schools have long been searching for better ways to prove their value, and in a data-centric world, there is enormous pressure to measure, measure, measure, and abide by partially obsolete college entrance requirements. Yet there is a strong consensus that the majority of currently used large-scale assessments are not comprehensive…

Physical activity is place-based, and being able to assess the number of people and their characteristics in specific locations is important both for public health surveillance and for practitioners in their design of physical activity spaces and programs. Although physical activity measurement has improved recently, many investigators avoid or…

The assessment movement that has emerged on American college campuses over the last twenty years emphasizes the need to carefully articulate the particular outcomes colleges seek for students, and it demands that faculty and administrators provide evidence of their students' success with respect to these outcomes. It also requires that this…

The Common Core State Standards for mathematics promote ideals about learning mathematics by providing specific standards focused on conceptual understanding and incorporating practices in which students must participate to develop conceptual understanding. Thus, how we define learning is pivotal because our current definition isn't aligned with…

The more recent discussion in Ireland around post-primary teachers being responsible for assessing their own students' work continues. The new junior cycle reform (covering the first three years of post-primary education) is concerned with making fundamental changes in approaches to learning, teaching, curriculum and assessment, with school-based…

This paper explores the potential of incorporating constructs of distributive justice and procedural justice into summative assessment of student learning in higher education. I systematically compare the process used by managers to evaluate employee performance in organizations--performance appraisal (PA)--with processes used by professors to…

Between 2012 and 2016, the Learning Metrics Task Force (LMTF) laid out an ambitious agenda for nations and the international community on how to define and measure learning in the context of the United Nations Sustainable Development Goals (SDGs). This report describes the process undertaken by a group of 15 "Learning…

Adopting a comparative perspective to address educational issues in different contexts was a hallmark of Jullien's work in the early-nineteenth century. Different emphases and approaches to comparative education methodology have emerged in recent times thanks to major developments in technology, but have these changes rendered Jullien's ideas…

Does assessment change what is being taught? Laurie Occhipinti uses an analogy to answer this question. While conducting research on economic development in a remote rural area of the Argentine Chaco, a community had received some public funds to construct a new community center. They discussed where to place the center. The middle of the village…

Results of a survey conducted by the Office for Civil Rights show that 6 million public school students (13%) are not attending school regularly. Chronic absenteeism--defined as missing more than 10% of school for any reason--has been negatively linked to many key academic outcomes. Evidence shows that students who exit chronic absentee status can…

This article reveals three emerging areas of conflict in the use of educational assessment instruments in compulsory education in Switzerland and outlines an analytical approach for detecting and analysing these areas of conflict. The approach combines a conceptual perspective, an evaluation perspective and a teaching perspective to show the…

The introduction of the International Classification of Functioning, Disability and Health has placed emphasis on framing health behavior as a multidimensional construct. In relation to childhood physical activity, this encompasses dimensions of functional performance, activity attendance, and subjective perceptions of involvement and enjoyment…

Global university rankings are often thought of as games, defined by roles and rules that universities must play in order to confirm their legitimacy and gain visibility as actors in the global academic market. While some countries are well represented at the top of rankings charts, others are just joining the race and testing out different…
