Forms and functions of on-the-fly formative assessment conversations in physics inquiry lessons
2020
This case study examined teachers’ on-the-fly formative assessment conversations, that is, how teachers collect information from students’ thinking and use that information to support their learnin...
Assessment On-the-Fly: Promoting and Collecting Evidence of Learning Through Dialogue
2018
International audience; Inquiry activities generate rich opportunities for STEM learning and for assessment. When teachers pay attention to assessment information collected during the course of learning, they are able to interpret and make decisions about such assessment data in a timely fashion that can drive future planning and support student learning, for example through feedback. This chapter focuses on how classroom talk can generate evidence of learning and how teachers can utilise this to enable assessment to guide inquiry learning. It looks at several vignettes from different countries of on-the-fly interactions in inquiry settings and unpacks how teachers organised, facilitated an…
Hybrid particle-continuum simulations coupling Brownian dynamics and local dynamic density functional theory
2017
We present a multiscale hybrid particle-field scheme for the simulation of relaxation and diffusion behavior of soft condensed matter systems. It combines particle-based Brownian dynamics and field-based local dynamics in an adaptive sense such that particles can switch their level of resolution on the fly. The switching of resolution is controlled by a tuning function which can be chosen at will according to the geometry of the system. As an application, the hybrid scheme is used to study the kinetics of interfacial broadening of a polymer blend, and is validated by comparing the results to the predictions from pure Brownian dynamics and pure local dynamics calculations.
Second generation Car-Parrinello molecular dynamics
2014
Computer simulation methods, such as Monte Carlo or molecular dynamics, are very powerful theoretical techniques to provide detailed and essentially exact informations on rather complex classical many-body problems. With the advent of ab initio molecular dynamics (AIMD), where finite-temperature dynamical trajectories are generated using interatomic forces which are calculated on the fly using accurate electronic structure calculations, the scope of computational research has been greatly extended. This review is intended to outline the basic principles as well as being a survey of the field. Beginning with the derivation of Born–Oppenheimer molecular dynamics, the Car–Parrinello method and…
