Moving forward with ethnomethodological approaches to analysing mathematics classroom interactions

Ethnomethodological approaches to research such as Interactionism, Conversation Analysis and Discursive Psychology have so far played only a small part in mathematics education research. This is in ... of psychology has not been widely taken up by researchers in mathematics education, or even educational research in general. So far in mathematics education research using this approach has focused on

The mathematics of market timing

market timing returns symmetric? If it is hard to obtain above average returns by market timing, is it also hard to obtain below average returns? What is the most basic mathematics of market timing? I try ... mathematics. Using perfect hindsight, it is easy to identify the best and worst possible market timing portfolios, which form the boundaries of the feasible return paths for all market timing portfolios, i.e

The use of educational platforms as teaching resource in mathematics

Dropping out from the school system at High School level has been a problem for several years; high levels of mathematics’ failing have been a recurring situation.

What Kind of Content Knowledge do Secondary Mathematics Teachers Need?

The discrepancy between school and academic mathematics as well as the resulting problems for secondary mathematics teachers’ content knowledge (CK) have been well known since Felix Klein pointed out ... mathematical knowledge: The mathematics teacher requires a general knowledge of mathematics in order to be able to communicate with other mathematicians and also to establish his credentials; but he also

Expression for a general element of an SO(n) matrix

We derive the expression for a general element of an SO(n) matrix. All elements are obtained from a single element of the matrix. This has applications in recently developed methods for computing ... matrix T ( 2 ) depends only on the next (n − 2) θi’s, namely, θn, θn+1, . . . , θ2n−3, and so on. Finally, the matrix T (n−1) depends only on one θi, namely, θn(n−1)/2. Thus, a general matrix T (k) is

Asymptotics for general nonstationary fractionally integrated processes without prehistoric influence

Proof, Proving and Mathematics Curriculum

The National Council of Teachers of Mathematics, a US based teachers association, strongly encourages teachers to make proof and reasoning an integral part of student mathematics. However, the ... . Polya (1960) writes that in mathematics as in the physical sciences we may use observation and induction to discover general laws. But there is a difference.
