Correct specifications of hierarchical attribute structures in analyses using diagnostic classification models (DCMs) are pivotal because misspecifications can lead to biased parameter estimations and inaccurate classification profiles. This research is aimed to demonstrate DCM analyses with various hierarchical attribute structures via Bayesian…

Modeling and simulation activities are common in secondary technology and engineering education classrooms. Virtual simulations are used to integrate engineering design into classroom instruction. The performance outcomes of a student's final virtual design usually depend on the level of knowledge application. When applying the learned content to…

Automatic machine learning (AutoML) methods automate the time-consuming, feature-engineering process so that researchers produce accurate student models more quickly and easily. In this paper, we compare two AutoML feature engineering methods in the context of the National Assessment of Educational Progress (NAEP) data mining competition. The…

This design and development research was motivated by the rapid expansion and use of GeoGebra by mathematics educators (teachers and lecturers) in Indonesia. One of GeoGebra features is GeoGebra Applet that can be used, modified, and/or developed by educators for dynamic and interactive mathematics teaching and learning. At the time of research…

Houston's experience with the Educational Value-Added Assessment System (R) (EVAAS) raises questions that other districts should consider before buying the software and using it for high-stakes decisions. Researchers found that teachers in Houston, all of whom were under the EVAAS gun, but who taught relatively more racial minority students,…

Many school counsellors have identified "cyber-bullying" among adolescent girls as a growing concern. In order to respond to this issue, this article begins with a new model of cyber-communications from the unique perspective of adolescent girls. Next, it explores the limitations of responding to this model, based on current understandings of…

In 2005, the U.S. Department of Education awarded eight Striving Readers grants to projects around the country. The goal of Striving Readers is to improve literacy skills and achievement for struggling readers in middle and high school and to increase the research base using randomized clinical research to address improvement in adolescent…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

Designed to offer direction for classroom teachers and administrators in the development of an exploratory computer literacy program for grades 7 and 8, this resource unit comprises four major sections, four appendices, and two resource lists. The introductory section provides information on the history of Hawaii's computer literacy program; cites…

This resource unit, an addendum to The Exploratory Computer Literacy Curriculum Guide, Grades 7-8, is designed to provide teachers with guidelines and classroom computer activities for integrating computer literacy into the curriculum. An overview of the guide is given in the introduction, which notes that the materials reflect the…

Vertical connections, constructed using inquiry, give students the skills to reach new heights in both their academic and local communities. In this article, the authors present inquiry projects, developed by middle level teachers, to ensure that students use higher-level thinking skills to improve the community. Each project is connected to the…
