Different ways in which students handle chance encounters in the explorative setting of a dice game

The purpose of this study is to investigate the ways in which Swedish seventh grade students (12 and 13 years old) handle chance encounters. Four groups of students working in pairs participated in the study. In the group discussions, which were tape-recorded and fully transcribed, the students were encouraged to explore strategies for winning a specifically designed dice game based on the sum of two dice. The dice game included four different set-ups of dice designed to bring to the fore different aspects of probability modelling and to offer the student the opportunity to encounter small differences in the mathematical structure of the sample space and of the probability distribution between the four different set-ups. The study describes strategies that the students use when confronted with these different set-ups, what their activities imply in terms of resources in handling random phenomena and what the dice game offers in terms of opportunities for learning probability. In order to explain such meaning-making processes the students’ activities are viewed from a perspective that takes into consideration how the students’ understanding varies with their interpretations of the situation they are confronted with, i.e., how they contextualize the different set-ups of the dice game. The results show how the students, during the course of the game, reorganize their interpretations of the mathematical content confronting them, and how a variation of guiding principles becomes the object of exploration. Approaches of extremes and a number model are described as a means for the students to identify and assign probabilities for the total of two dice.

Great expectations: a critical perspective on Open Educational Resources in Brazil

ABSTRACT

Nearly two decades have passed since the Open Educational Resources (OER) movement was launched. Its success in Brazil can be illustrated with the establishment of a UNESCO Chair in Open Education in 2014, in one of the country’s most prestigious universities. Crucially, OER were included in the 2014–2024 National Education Plan, a key piece of national educational legislation, as a category of educational technologies framed as tools. Assuming metaphors such as this play a key role in the ways we think, speak and act, this article presents a critical perspective on OER in Brazil. Examining the implications of the main metaphors used to construe OER in local media and academic sources, the text argues that these metaphors reflect hegemonic discourses on educational technology, concealing the non-neutrality of technological artefacts, obscuring issues concerning curriculum and pedagogy, and overlooking actual local needs. The article discusses issues concerning local OER advocacy, positioned in respect to specificities of a context where education, albeit a constitutionally established right, may be poised to undergo radical changes in the near future.
