Mathematics is in a dramatic and massive process of changing, mainly due to the advent of computers and computer science. Our aim is to present a pocket image of this phenomenon; a “case study” will give us the opportunity to describe some of these new ideas, problems, and techniques. Particularly, we will be concerned with foreseeable mutations in the interaction between deductive and experime...
A set A of nonnegative integers is recursively enumerable (r.e.) if A can be computably listed. It is shown that there is a rst order property, Q(X), de nable in E, the lattice of r.e. sets under inclusion, such that: (1) if A is any r.e. set satisfying Q(A) then A is nonrecursive and Turing incomplete; and (2) there exists an r.e. set A satisfying Q(A). This resolves a long open question stemm...
The National curriculum of Islamic Republic of Iran has been focused on promoting students’ modeling skills. In consideration of this emphasis, this study has investigated the attitudes towards mathematics and the views towards mathematical modeling problems of 244 students in grade 10. This research was conducted with a pre-test, followed by an educational intervention and a post-test. During ...
The aim of this study was the compression of emotional problems, hyper activity and conduct disorders in students with learning disabilities in reading (dyslexia), mathematics (dyscalculia), and normal students. The research method was descriptive and causal – comparative and the sample was 150 elementary school students in Tabriz in the 2015-2016 Academic years. All samples were chosen by av...
Abstract The main purpose of the study is to design a valid model for the problem-oriented curriculum in elementary mathematics. The research approach is quantitative. In designing the model, which was done by structural-interpretive modeling method, 19 specialists of curriculum planning and mathematical education of Arak city participated. To determine the validity, with the method of partial ...
