Simulation or game-based assessments produce outcome data and process data. In this article, some statistical models that can potentially be used to analyze data from simulation or game-based assessments are introduced. Specifically, cognitive diagnostic models that can be used to estimate latent skills from outcome data so as to scale these…

The purpose of this research is to establish common ground on how faculty development should be instituted and the needs it should address on an international level, with its major focus being the development of competencies. A survey was developed and distributed to a sample of 764 university teaching professionals. Results show that 90% find…

Lorraine Day provides us with a great range of statistical investigations using various resources such as maths300 and TinkerPlots. Each of the investigations link mathematics to students' lives and provide engaging and meaningful contexts for mathematical inquiry.

An experiment is described that determines the activation energy (E[subscript a]) of the iodide-catalyzed decomposition reaction of hydrogen peroxide in a much more efficient manner than previously reported in the literature. Hydrogen peroxide, spontaneously or with a catalyst, decomposes to oxygen and water. Because the decomposition reaction is…

In this article, Tammy D. Lee and Jane L. Lubischer describe a classroom lesson designed to explore how animals use sound to communicate and how this communication affects their survival. Lee and Lubischer wanted to bring an awareness of how science is happening in students' own backyards. They developed a half-day 5E lesson integrating two…

The student population across U.S. schools has become increasingly diverse and has presented educators with a number of concerns in assisting students demonstrating challenging behaviors. Educators have historically had difficulties in distinguishing between cultural differences and genuine indicators of emotional and behavioral disorders. It is…

This article describes three types of data that can impact how instructional coaches face the challenges in measuring the impact of their work with teachers on student learning. Descriptions of the three types of data--"shifts in teacher reflective tendencies," "the use of student performance as an indicator of success," and…

Many current national and institutional education policies address the issue of raising participation amongst young people and enhancing employability after leaving school or university. What sort of information are these policies built on? This paper compares national information systems from the last three decades across Europe that gather…

District and state data systems are constructed to ensure that individuals can access only the data that are appropriate for their role. Still, questions from the public about how these data systems work and how student privacy is protected have been increasing. A recurring concern is the feared existence of a "permanent record"--a…

Teachers need longitudinal student-level data, such as attendance history, course-taking patterns, grades, and test scores, to tailor instruction to individual students' strengths and weaknesses. This factsheet uses the findings from the "Data for Action 2013" analysis to discuss how states can provide teachers with student-level…

This booklet grew out of a half-day class on equating that author Samuel Livingston teaches for new statistical staff at Educational Testing Service (ETS). The class is a nonmathematical introduction to the topic, emphasizing conceptual understanding and practical applications. The class consists of illustrated lectures, interspersed with…

Many states collect data on students and teachers, but linking teachers to students by course--the teacher-student data link (TSDL)--at the state level is critical to understanding the connection between student academic growth and teacher training, qualifications, and practice. This roadmap discusses the six key areas DQC recommends focusing on…

As the nation's largest provider of postsecondary education, community colleges are instrumental to workforce development, but measuring student outcomes is challenging after students have left for the workplace. Many states use existing administrative data such as unemployment insurance records to calculate employment outcomes at minimal marginal…

Understanding neurocognitive mechanisms in children with autism spectrum disorder (ASD) is an essential goal of autism research. Studying young children with ASD or other neurodevelopmental conditions in demanding experimental settings, however, can pose many practical and ethical challenges. In this article, we present practical strategies that…

This case study describes the research carried out in partial fulfilment of the degree of doctor of education. The study was qualitative in nature with a phenomenological interpretive paradigm. My primary objective is to share my experience of combining life story and grounded theory research. My main objectives for undertaking the research were…
