In a substantial number of studies, the theory has been used to analyze teaching and students' learning in classrooms. In mathematics education, variation theory has also been used to explore variation in sets of instructional examples. For example, it has been reported how teachers, by using ...
Write the expression (1/16)^(x/2) in the form 2^(kx) or 3^(kx) for a suitable constant k. Write each expression in the form 2^kx or 3^kx for a suitable constant k. 1) (4\/9)^x 2) (1/81)^x Is 8x + 9y = 10 a direct variation, and if so, what is the constant?
(Mathematics) Having no fixed quantitative value. Inconstant Changing or varying, especially often and without discernible pattern or reason. Variable Something that varies or is prone to variation. Inconstant Fickle; faithless. Variable (Astronomy) A variable star. Inconstant Not constant; wavering. Va...

However, the power of this interpretation becomes more apparent when one then imports concepts from probability theory (together with all their attendant intuitions and tools), such as independence, conditioning, stationarity, total variation distance, and entropy. For instance, suppose we want to ...
Variation theoryExplaining appears to dominate primary teachers' understanding of mathematical reasoning when it is not confused with problem solving. Drawing on previous literature of mathematical reasoning, we generate a view of the critical aspects of reasoning that may assist primary teachers when ...
(Mathematics) A function that relates the values of one variable to those of other variables. Variance An exception to the application of a usual rule, granted by an authority on the basis of hardship or practicality A zoning variance. Variation A form that is an altered version of a given...
In recent years, the application of digital technologies for learning purposes is increasingly discussed as smartphones have become an integral part of students’ everyday life. These technologies are particularly promising in the so-called “transition-in” phase of the student lifecycle when first-...
Chaos theory is closely linked to thebutterfly effect,the idea that a very slight variation in initial conditions can result in substantial changes in output values. This runs counter to the intuitive idea that similar initial conditions should result in roughly similar outputs. ...
