5 paź 2010 · Described as a social interaction scale (Jonassen & Grabowski, Citation 1993), the style of learning interaction model focuses on learner preferences but introduces social and affective dimensions to the measurement of style. The three dimensions described by the model are: avoidant‐participant; competitive–collaborative and dependent ...

10 sty 2017 · We argue that it is ‘about time’ that time became a focus for theorising, methodological reflection and empirical work in sociology of education because the conditions of time are in flux (see Julie McLeod, Robert Hassan and Greg Thompson and Ian Cook in this special issue).
A time-domain reflectometer (TDR) is a measurement tool used to measure the impedance profile of a component (device) under test (DUT). The concept is straightforward. Using a step generator and an oscilloscope, a fast pulse edge is launched into the DUT.
This chapter considers ‘social learning’, broadly defined as learning that is facilitated by observation of, or interaction with, another individual (or its products). Of most interest is social learning that results in ‘social transmission’: the observer adopting behaviour patterns matching those of the demonstrator.
This paper compares vector-network-analyzer- and oscilloscope-based time-domain reflectometers and their recent advances.
30 sty 2015 · designers prefer working in the time domain with logic analyzers and high-speed oscilloscopes. When compared to other measurement techniques, time domain reflectometry provides a more intuitive and direct look at the DUT’s characteristics.
Abstract—Time-domain reflectometry (TDR) is an established means of measuring impedance inhomogeneity of a variety of waveguides, providing critical data necessary to characterize and optimize the performance of high-bandwidth computational and communication systems.
