Eric.ed.gov – Math in Art or Art in Math.

eric.ed.gov har udgivet: The concept of integrating mathematics and art course work broadens an appreciation of the connection between the two. Although calculations and getting the right answer have traditionally been the focus of mathematics at the secondary level, other topics have recently begun to be addressed, such as mathographics, or the relationship between art and mathematics, and creative constructions and shapes. Art instruction also includes considerable instruction in mathematics, as artists need to understand such concepts as parallel lines, visual distance, and perspective distortion. Moreover, many examples of mathematics in art works exist, such Albrecht Durer’s use of grids in woodcuts and Salvador Dali’s use of the hypercube, while there are also many examples of literature that support the mathematics/art connection. In interrelating mathematics and art at the college… Continue Reading

Eric.ed.gov – “Double-Dosing” in Math in North Carolina Public Schools. REL 2016-140

eric.ed.gov har udgivet: Double-dosing in math expands the time for students to learn by having them enroll in two (or occasionally more) math courses during the regular school day. Although the practice can take different forms and be used at different grade levels (Chait, Muller, Goldware, & Housman, 2007; Nomi & Allensworth, 2009), most research on double-dosing in math has focused on students who need preparation to make the transition to Algebra I or similar rigorous high school math courses–typically, grade 8 or grade 9 students. This study aims to provide a more complete picture of the prevalence of double-dosing in math in North Carolina in 2011/12, the most recent year that data were available. It also reports on the use of double-dosing for remediation, maintenance, and enrichment; compares schools… Continue Reading
