Number Knowledge And Error Types Of Elementary Portuguese Students: Implications For Instruction, Silvana Watson, Sharon Judge, João Lopes, Célia Oliveira, Ana Catarina Jesus

Communication Disorders & Special Education Faculty Publications

In the present study, we examined number knowledge skills of 697 Portuguese elementary students from first to fourth grade. Students completed three number knowledge tasks: 1) translating numbers into words, 2) symbolic magnitude (i.e., number comparison), and 3) decomposing numbers. We evaluated students’ answers by means of error analysis using a three-category coding system adopted from specific error types were computed by grade level. Results showed that there were significant differences among grades and that the prerequisite linguistic error type (i.e., pre linguistic rules or principles of the cardinal number system), particularly in the magnitude tasks, significantly contributed to students’ …

Java Based Visualization And Animation For Teaching The Dijkstra Shortest Path Algorithm In Transportation Networks, Ivan Makohon, Duc T. Nguyen, Masha Sosonkina, Yuzhong Shen, Manwo Ng

Civil & Environmental Engineering Faculty Publications

Shortest path (SP) algorithms, such as the popular Dijkstra algorithm has been considered as the "basic building blocks" for many advanced transportation network models. Dijkstra algorithm will find the shortest time (ST) and the corresponding SP to travel from a source node to a destination node. Applications of SP algorithms include real-time GPS and the Frank-Wolfe network equilibrium.

For transportation engineering students, the Dijkstra algorithm is not easily understood. This paper discusses the design and development of a software that will help the students to fully understand the key components involved in the Dijkstra SP algorithm. The software presents an …

Disaster Prevention Literacy Among School Administrators And Teachers: A Study On The Plan For Disaster Prevention And Campus Network Deployment And Experiment In Taiwan, Sung-Chin Chung, Cherng-Jyh Yen

Educational Leadership & Workforce Development Faculty Publications

Taiwan is located at the high-risk region of natural disasters with the frequently occurred earthquakes. The importance of the disaster prevention education on campus is made even more obvious by the fact that natural disasters often occur during the school days. Given the leading roles the school administrators and teachers playing in the disaster prevention education of their pupils, this study purposed to investigate how disaster prevention literacy was among them and how disaster prevention literacy differed across various background variables of them. Furthermore, the current study also examined if disaster prevention literacy changed by participation in the disaster prevention …

Probing The Landscape: Toward A Systematic Taxonomy Of Online Peer Assessment Systems In Education, Dymytro Babik, Edward F. Gehringer, Jennifer Kidd, Ferry Pramudianto, David Tinapple

Teaching & Learning Faculty Publications

We present the research framework for a taxonomy of online educational peer-assessment systems. This framework enables researchers in technology-supported peer assessment to understand the current landscape of technologies supporting student peer review and assessment, specifically, its affordances and constraints. The framework helps identify the major themes in existing and potential research and formulate an agenda for future studies. It also informs educators and system design practitioners about use cases and design options.
