Disipline Problems at Eight Grade

Eight Open Problems in Distributed Computing

Distributed Computing Theory continues to be one of the most active research fields in Theoretical Computer Science today. Besides its foundational topics (such as consensus and synchronization), it is currently being enriched with many new topics inspired from modern technological advances (e.g., the Internet). In this note, we present eight open problems in Distributed Computing Theory that s...

Identifying at Highway-Rail Grade Crossing Hotspots in Canada

This research presents a risk-based Hotspots identification model at highway-rail grade crossings in Canada. Two sets of models were developed to predict collision frequency and consequence at individual crossings. A two–dimensional graphic approach was adopted to combine these two models together to predict the risk at each crossing. Hotspots based on collision history tended to be widespread ...

Using dynamic geometry software to improve eight grade students’ understanding of transformation geometry

This study examines the effect of dynamic geometry software (DGS) on students’ learning of transformation geometry. A preand post-test quasi-experimental design was used. Participants in the study were 68 eighth grade students (36 in the experimental group and 32 in the control group). While the experimental group students were studying the transformation geometry in a (DGE), the same instructi...

The Extent of Using Real Problems and Emphasizing Modelling in the 10th Grade Math Textbook

Modelling is emphasized heavily in the national math curriculum, yet the extent to which this concept is covered in the math textbooks is, while of great importance, unknown. To discover the extent to which this issue, and real problems in general, are covered in the 10th grade math textbooks, the content of the textbook for the ‘theoretical’ (“nazari”) branch was analyzed. In doing so, the vie...
