Visualizing pre-service biology teachers´ conceptions about population dynamics in ecosystems

Meister, Sabine; Zimmerman, Corinne; Upmeier zu Belzen, Annette

The Balance of Nature (BoN) metaphor leads to various naïve conceptions about ecosystem dynamics that do not address current scientific theories adequately. An appropriate alternative is the Flux of Nature (FoN) metaphor. ...

Learning Enabled Optimization: Towards a Fusion of Statistical Learning and Stochastic Optimization

Sen, Suvrajeet; Deng, Yunxiao

Several emerging applications, such as “Analytics of Things" and “Integrative Analytics" call for a fusion of statistical learning (SL) and stochastic optimization (SO). The Learning Enabled Optimization paradigm fuses ...

A randomized method for handling a difficult function in a convex optimization problem, motivated by probabilistic programming

Fábián, Csaba I.; Szántai, Tamás

We propose a randomized gradient method for the handling of a convex function whose gradient computation is demanding. The method bears a resemblance to the stochastic approximation family. But in contrast to stochastic ...

Assessment of meta-modeling knowledge: Learning from triadic concepts of models in the philosophy of science

Meta-modeling knowledge is an established construct in science education, typically conceptualized in frameworks encompassing hierarchically ordered levels of understanding specific for different aspects (e.g., purpose of ...
