This article discusses the development of an interactive online textbook for undergraduate teaching, in response to moving teaching online due to COVID-19. The development took place initially for a university with less than 5% of students studying online in 2019. The online textbook was incorporated into a large, diverse, multidisciplinary and…

In this largely theoretical article, we discuss the relation between a kind of affect, behavioural schemas and aspects of the proving process. We begin with affect as described in the mathematics education literature, but soon narrow our focus to a particular kind of affect--nonemotional cognitive feelings. We then mention the position of feelings…

We analyse the origin and development of an Experimental Design course which has been taught in several faculties of the Universidad de la Republica and other institutions in Uruguay, over a 10-year period. At the end of the course, students were assessed by carrying out individual work projects on real-life problems, which was innovative for…

In order to learn the concept of statistical techniques one needs to run real experiments that generate reliable data. In practice, the data from some well-defined process or system is very costly and time consuming. It is difficult to run real experiments during the teaching period in the university. To overcome these difficulties, statisticians…

A course in applied statistics for social science students provides for students designing experiments at an interactive terminal. (SD)

The usual formula for variance depending on rounding off the sample mean lacks precision, especially when computer programs are used for the calculation. The well-known simplification of the total sums of squares does not always give benefit. Since the variance of two observations is easily calculated without the use of a sample mean, and the…

This is a critique of a study investigating the reliability and validity of objective measures of students' reactions to courses. (MK)
