Every second Tuesday, CBA staff gather for lunch and a talk. December 7th will mark our last talk of the semester, given by Nicolas Valiente Parra. CBA staff will gather for a small Christmas lunch.

Computational thinking (CT) has been added to many educational standards around the world. However, this new content presents challenges around preparing teachers to incorporate computational thinking into the STEM disciplines. In this talk, I will first give a review of the literature around preparing pre-service secondary STEM teachers to incorporate computational thinking into their subjects. I will then present data from interviews with pre-service secondary subject teachers in the STEM teacher education program at UiO . The data highlight a current gap in the research on teacher preparation: that the computation learned in upper division subject courses does not directly translate to the computational thinking that they will be teaching their future students. Finally, I give some suggestions for remedying this gap.

Yet a different year is coming to an end. We are hopeful that time allows us to gather the Norwegian partners in CENSSS for a informal Christmas lunch.

"Extrapolating the Electric Dipole Moment"

Winter school at University of Oslo

Njord Seminar with Richard Walker (Leicester University): The rock record of igneous sheet intrusions: the preservation of magma emplacement processes

Abstract: Transport and mixing in multiphase flow through porous media plays a key role in a range of biological, geological, and engineered systems. Here, we use numerical simulations to investigate the effect of intermittent multiphase flow on fluid stretching and folding, a fundamental mechanism driving solute mixing and reaction in porous media. We show that, in contrast to steady single-phase flows, the concurrent flow of two immiscible phases induces chaotic mixing, characterized by exponential stretching in the pore space. The stretching rate is found to decay with increasing capillary number, implying that the increasing flow intermittency observed at lower capillary numbers enhances the mixing efficiency. We propose a mechanistic model to link the basic multiphase flow properties to the chaotic mixing rate, opening new perspectives to understand mixing and reaction in multiphase porous media flows. The results presented here form part of the background for the recently started RCN-funded project M4: Mixing in Multiphase flow through Microporous Media, which will also be introduced.

This talk is part of the Mechanics Lunch Seminar series. Bring-your-own-lunch and lots of questions.

Abstract:  The cerebral circulation must ensure continuous blood perfusion of the brain which is the biggest oxygen consumer in the human body. It must also provide mechanisms for adaptability to changing oxygen demand as well as resilience to local blockages. We will look at such mechanisms at the level of the microcirculation where the mechanics of blood flow is dominated by red blood cells. We will find that red blood cells do not only play the role of oxygen carriers, but that they are an important element of blood flow regulation itself. To this end, we will compare results from in vitro studies in microfluidic chips to theoretical and computational models and to in vivo data from mice. We will derive local auto-regulation mechanisms for blood flow and will study how local modifications in the vascular network can modify the global hematocrit distribution. These results will emphasize the relevance of red blood cell mechanics and microvascular network geometry in cerebral blood perfusion.

NordCO₂ is collaborating with the ITN CO₂PERATE to organise the 2021 Winter School, which will take place over the course of three days from the 22nd to the 24th of November this year.

I will present a possible model for task design of mathematical programming problems (MPPs), where both the overarching design and a concrete example is given.

Following the implementation of the design into a mathematics classroom, I will present the students interactions when they were working on MPPs as well as a short analysis of the findings.

Finally, presenting the types of obstacles students encounter when working on MPPs and a discussion regarding the different types. There will be examples from the MPPs, experiences from the implementation, and questions/discussion throughout the module.
