Exploring STEM postsecondary instructors' accounts of instructional planning and revisions

discipline specific instruction (e.g., engineering curriculum, social science teachers, geology pedagogy)

Erdmann R, Miller K, Stains M.
GSID: tHJ4s-ML3DAJ
R Erdmann, K Miller, M Stains - International Journal of STEM Education, 2020 - Springer

… this study had teacher-centric mindsets with respect to their instructional planning (eg, content-… Finally, we found that pedagogical discontent was not a driver of planned course revisions. … Discipline and classification were correlated, with mathematics and geology class...

Nature communications

Baeumer C, Schmitz C, Ramadan AH, Du H, Skaja K, Feyer V, Müller P, Arndt B, Jia CL, Mayer J, De Souza RA, Michael Schneider C, Waser R, Dittmann R.
PMID: 26477940
Nat Commun. 2015 Oct 19;6:8610. doi: 10.1038/ncomms9610.

The demand for highly scalable, low-power devices for data storage and logic operations is strongly stimulating research into resistive switching as a novel concept for future non-volatile memory devices. To meet technological requirements, it is imperative to have a...

Surface Termination Conversion during SrTiO3 Thin Film Growth Revealed by X-ray Photoelectron Spectroscopy.

Scientific reports

Baeumer C, Xu C, Gunkel F, Raab N, Heinen RA, Koehl A, Dittmann R.
PMID: 26189436
Sci Rep. 2015 Jul 20;5:11829. doi: 10.1038/srep11829.

Emerging electrical and magnetic properties of oxide interfaces are often dominated by the termination and stoichiometry of substrates and thin films, which depend critically on the growth conditions. Currently, these quantities have to be measured separately with different sophisticated...
