This study aims to compare normality tests in different sample sizes in data with normal distribution under different kurtosis and skewness coefficients obtained simulatively. To this end, firstly, simulative data were produced using the MATLAB program for different skewness/kurtosis coefficients and different sample sizes. The normality analysis…

Power analysis based on the analytical t-test is an important aspect of a research study to determine the sample size required to detect the effect for the comparison of two means. The current paper presents a reader-friendly procedure for carrying out the t-test power analysis using the various R add-on packages. While there is a growing of R…

Researchers, federal and state policy leaders and administrators, and center directors all seek to understand what drives high quality Early Care and Education (ECE). The Assessing the Implementation and Cost of High Quality Early Care and Education, or ICHQ (pronounced I-check) project, led by Mathematica and funded by the Office of Planning,…

The statewide program review process for Illinois community colleges required by the Illinois Community College Board (ICCB) is scheduled on a five-year cycle, however, the value of program review is lost without regular opportunities for engagement and reflection on what has been learned through the process (Eggleston, 2020). Furthermore, one of…

Digitally-based assessments create opportunities for collecting moment to moment information about how students are responding to assessment items. This information, called log or process data, has long been regarded as a vast and valuable source of data about student performance. Despite repeated assurances of its vastness and value, process data…

The purpose of this research was to create a Culture of Assessment Instrument (Appendix F) that will allow education program provider (EPP) assessment leaders to measure the assessment culture within their program. General Systems Theory was the theoretical framework as the foundation of this research. Using a modified Delphi panel of assessment…

Once research questions are posed, researchers must answer many a priori questions regarding research design before analysis can be performed and any conclusions can be made, including sample selection criteria, data collection method, model specification, analysis and estimation technique. The choices made by researchers along this forking path…

Recently, Bayesian diagnostic classification modeling has been becoming popular in health psychology, education, and sociology. Typically information criteria are used for model selection when researchers want to choose the best model among alternative models. In Bayesian estimation, posterior predictive checking is a flexible Bayesian model…

The COVID-19 pandemic has created the largest disruption of education systems in human history, affecting nearly 1.6 billion learners in more than 200 countries. Closures of schools, institutions and other learning spaces have impacted more than 94% of the world's student population. This has brought far-reaching changes in all aspects of our…

Traditionally, the key principle of assessment was based on the depth and intensity of the knowledge taught in class. In our modern state, the notion of assessment is more about learning and less about whether it is deep or surface learning. This could be attributed to challenges facing higher education, such as marketisation, massification,…

Scientific Practices play a central role in the Next Generation Science Standards, influencing the standards of more than 70% of students in the United States. Therefore, a view of what has been studied about Scientific Practices in Science Education, globally in the past decade is relevant. Thus, 44 articles from international journals in Science…

The research aimed to analyze the students' abilities in solving realistic mathematics problems using "What-If"-Ethnomathematics Instruments with content focused on plane and space materials. The "What-If"-Ethnomathematics instruments are instruments that enable educators to analyze various errors and obstacles experienced by…

The purpose of this study was to explore how teachers experience blended teaching and learning. This article describes the interplay of beliefs and practices of four high school teachers, based on interview data, observation data, and artifact analysis. Results showed that the four teachers in the study enacted their beliefs in the blended…

The rapid pace of globalization has contributed to the expansion of fully online programs and course offerings over the past decades. Additionally, the current COVID-19 pandemic accelerated the move to online instruction worldwide. Various challenges have become evident when transitioning to online education. Thus, this qualitative case study…

Over past decade, districts throughout the United States have reformed their teacher evaluation systems in order to support teachers to improve teacher practices and to improve the composition of teachers in the workforce. Despite the widespread reform of evaluation systems, little research has examined the impacts these systems have on teacher…
