How to identify at-risk students in open online courses has received increasing attention, since the dropout rate is unexpectedly high. Most prior studies have focused on using machine learning techniques to predict student dropout based on features extracted from students' learning activity logs. However, little work has viewed the dropout…

This research connects several data-driven educational data mining approaches to a framework for interaction developed in educational research. In particular, 10 million usage data points collected by a Learning Management System used by students and teachers in 450 online undergraduate courses were analyzed with this framework. A range of…

This white paper explores the variation among Part C exiting categories as reported by the 50 states and Washington, D.C., using 2012-13 exiting data. Examining factors that may contribute to variation can lead to improved Part C exiting data quality within and across states. Examination of the Part C exiting data shows that 8 of the 10 categories…

Independent and original thinking are the concepts which define critical thinking. A critical thinker doesn't passively accept other people's views and thoughts, on the contrary he constitutes his own thoughts by analyzing them. This independence liberates his mind, heart and actions (Doganay and Ünal, 2006). In this context, the definition of…

The four representative models that define oxidation-reduction reactions are often used differently in different situations or contexts in chemistry textbooks. Although integrated models have been suggested to overcome the confusion caused by this, they have not been successful. We therefore aim to interpret the causes for difficulties in the…

PISA study has defined several key areas to be paid attention to by teachers. One of these areas is work with models. The term model can be understood very broadly, it can refer to a drawing of a chemical reaction, a plastic model, a permanent mount (taxidermy) to advanced 3D projections. Teachers are no longer confined to teaching materials and…

We use administrative data to measure whether attending a charter school in Denver, Colorado, reduces the likelihood that students are newly classified as having a disability in primary grades. We employ an observational approach that takes advantage of Denver's Common Enrollment System, which allows us to observe each school that the student…

Computerized classification of student answers offers the possibility of instant feedback and improved learning. Open response (OR) questions provide greater insight into student thinking and understanding than more constrained multiple choice (MC) questions, but development of automated classifiers is more difficult, often requiring training a…

The objective of this research is to understand the diversity of gifted students' self-representations through self-portrait analysis. Two hundred twenty-seven French gifted students (intelligence quotient = 130; 45 girls, 182 boys), aged from 9 to 15 years completed the GPS instrument ("Genèse des Perceptions de Soi" [Genesis of the…

Children acquiring languages with noun classes (grammatical gender) have ample statistical information available that characterizes the distribution of nouns into these classes, but their use of this information to classify novel nouns differs from the predictions made by an optimal Bayesian classifier. We use rational analysis to investigate the…

Evidence-based reforms that emphasize the identification and implementation of empirically validated practices are at the forefront of educational research, and recently, the Council for Exceptional Children (CEC; 2014) published a set of standards for establishing evidence-based practices in special education. Although 30 years of research…

To guarantee equal opportunities and treatment in employment for individuals with disabilities, Congress enacted Title I of the Americans with Disabilities Act (ADA) in 1992. This law states, "No covered entity shall discriminate against a qualified individual on the basis of disability in regard to job application procedures, the hiring,…

The high-school chemistry curriculum is loaded with many important chemical concepts that are taught at the high-school level and it is therefore very difficult to add modern contents to the existing curriculum. However, many studies have underscored the importance of integrating modern chemistry contents such as nanotechnology into a high-school…

This study evaluated the classification accuracy of a second grade oral reading fluency curriculum-based measure (R-CBM) in predicting third grade state test performance. It also compared the long-term classification accuracy of local and publisher-recommended R-CBM cut scores. Participants were 266 students who were divided into a calibration…

In order for hope to be a sufficient state of mind, deliberate efforts, energies and actions are required in a way that embraces the other side of hope, namely, pain and/or despair. In other words, there must be an agreement that life consists of hopes/dreams and pain/despair. In the work of Duncan-Andrade, he gives us a reflective framework for…
