In this study, we investigated undergraduate mathematics students’ (N = 267) attitudes towards proving. The students were taking an intro

In addition, since the survey time of each round spans the whole academic year, this article calculates the time from September 2013 (seventh-grade enrollment) to the survey time point (junior high school, with the month as the unit of measurement) to control for the impacts of the time ...

A light-year is a unit of distance (the distance light travels in a year), not of time. Improper use of units leads to meaningless results, and correct use of units can be used to verify results. As an example, consider this: The unit of mass is (mass). The unit of ...
These goals “may be oriented toward content or toward building a classroom community. Content goals tend to be more short-term, reflecting major aspects of the teacher’s agenda for the day or unit” (p. 50). Finally, there are local goals related to specific circumstances. Schoenfeld [1]...
-known conjecture in representation theory. In each area, we demonstrate how the framework has successfully helped guide the mathematician to achieve the result. In each of these cases, the necessary models can be trained within several hours on a machine with a single graphics processing unit....
刊名:Applications of Mathematics 2019年第1期摘要:A 0/1-simplex is the convex hull of n+1 affinely independent vertices of the unit n-cube I-n. It is nonobtuse if none of its dihedral angles is obtuse, and acute if additionally none of them is right. Acute 0/1-simplices in I-n ...
As shown in Figure 1, the deterministic potential of cancer diminishes with advancing stage. Simultaneously, as chaos increases, the ability to determine diminishes. This has been elegantly demonstrated in cellular studies as well.11 Clinically, the diminishing determinism is similar to the lack of ...
unit tens or the appropriate groups of ones. While some drew on a conception that enabled them to explain the algorithm in at least one way, few exhibited an understanding of numbers that enabled them to explain the algorithm flexibly, including why the digits in any column can be treated ...
