Abstract The pandemic situation forces the educational system to respond to a variety of issues. During the pandemic, it’s essential to learn more about Technological-Pedagogical-Content-Knowledge (TPACK) and how it can be incorporated into pre-service physics teacher preparation. This qualitative research collects data from ten online teaching videos and ten offline teaching videos of 20 pre-service physics teachers. This study attempts to comprehend the appearance of each TPACK component by analyzing the videos with an observation sheet. The observation sheet explored seven components of TPACK, which are Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK), Pedagogical and Content Knowledge (PCK), Technological and Content Knowledge (TCK), Technological and Pedagogical Knowledge (TPK), and the last is Technological, Pedagogical and Content Knowledge (TPACK) itself. The result showed that pre-service teachers were determined good TPACK skills, but lacked in certain components. From the result, in both online and offline microteaching, participants rarely showed their TPK. In online activities, it is also seen that participants were faced difficulties in applying their PCK. The different nature of online and offline microteaching drives the need for teacher education institutions to plan and implement microteaching in the pedagogical courses to improve pre-service teachers’ TPACK in both situations.

The physical foundations for the use of electron energy loss spectroscopy towards analytical purposes, seem now rather well established and have been extensively discussed through recent publications. In this brief review we intend only to mention most recent developments in this field, which became available to our knowledge. We derive also some lines of discussion to define more clearly the limits of this analytical technique in materials science problems.The spectral information carried in both low ( 0<ΔE<100eV ) and high ( >100eV ) energy regions of the loss spectrum, is capable to provide quantitative results. Spectrometers have therefore been designed to work with all kinds of electron microscopes and to cover large energy ranges for the detection of inelastically scattered electrons (for instance the L-edge of molybdenum at 2500eV has been measured by van Zuylen with primary electrons of 80 kV). It is rather easy to fix a post-specimen magnetic optics on a STEM, but Crewe has recently underlined that great care should be devoted to optimize the collecting power and the energy resolution of the whole system.
