MATHEMATICAL ANALYSIS OF TRUCKS BLOCKING ROADWAY SIGNS
Civil Engineering and Environmental Systems, 2000Abstract The problem of obstructed road signs is significant because a missed sign can lead to driver confusion and, consequently, safety hazards. One of the main instances when drivers experience blocked road signs is when a passenger car in the left lane has their field of vision obstructed due to the presence of a large truck in the right lane ...

Mathematical Signs and Their Cultural Transmission in Pretend Play
2020Mathematics is a critical aspect of early childhood curricula and integral to competency in all STEM subjects. Developed historically, the abstract symbolic language of mathematics is a powerful cultural phenomenon. Using a genetic approach to research the beginning mathematical inscriptions of 3-4-year-olds has highlighted their meaning-based symbol ...

Teaching Mathematics Vocabulary with an Interactive Signing Math Dictionary
Journal of Research on Technology in Education, 2013AbstractState frameworks and national standards are explicit about the mathematics content that students must master at each grade level. Although the Individuals with Disabilities Education Act and the No Child Left Behind Act mandate that students who are deaf or hard of hearing and communicate in sign language have access to this content, evidence ...

Analysis on Semiosis of Mathematical Signs in the Mathematical Modeling
The Korean Society of Educational Studies in Mathematics - Journal of Educational Research in MathematicsThis study aims to analyze the process of mathematical modeling, focusing on how students generate mathematical representations and how the generation and modification of these representations relate to the mathematical modeling process. Particularly, this study examines, from Peirce's semiotic perspective, which characteristic among iconic, indexical,

Competent Workplace Mathematics: How Signs Become Transparent in Use
International Journal of Computers for Mathematical Learning, 2003Past research has shown that many scientists, when asked to interpret unfamiliar graphs that have nevertheless been culled from introductory undergraduate courses in their own field, experience problems and cannot give the standard answer accepted in the field.
