A Review of Reviews on Computational Thinking Assessment in Higher Education

Stem education interventions

Specht M.
GSID: WA4W9R4neqwJ
X Zhang, M Specht - CTE-STEM 2022 conference, 2022 - proceedings.open.tudelft.nl

There is an urgent need for educating the next generation of learners with digital tools and making use of digital practices and skills. Education on computational thinking (CT) is widespread around the world with a dominant focus on K-12....

A nanoscale demonstration of hydrogen atom spillover and surface diffusion across silica using the kinetics of CO2 methanation catalyzed on spatially separate Pt and Co nanoparticles.

Nano letters

Beaumont SK, Alayoglu S, Specht C, Kruse N, Somorjai GA.
PMID: 25026434
Nano Lett. 2014 Aug 13;14(8):4792-6. doi: 10.1021/nl501969k. Epub 2014 Jul 17.

Hydrogen spillover is of great importance to understanding many phenomena in heterogeneous catalysis and has long been controversial. Here we exploit well-defined nanoparticles to demonstrate its occurrence through evaluation of CO2 methanation kinetics. Combining platinum and cobalt nanoparticles causes...

Evolution of petaloidy in the zingiberales: An assessment of the relationship between ultrastructure and gene expression patterns.

Developmental dynamics : an official publication of the American Association of Anatomists

Rocha de Almeida AM, Yockteng R, Specht CD.
PMID: 25866364
Dev Dyn. 2015 Sep;244(9):1121-1132. doi: 10.1002/dvdy.24280. Epub 2015 Jul 02.

BACKGROUND: The development of petal-like organs has occurred repetitively throughout angiosperm evolution. Despite homoplasy, it is possible that common underlying molecular mechanisms are repeatedly recruited to drive the development of petaloid organs. In Zingiberales, infertile, petal-like structures replace fertile...

Listening to Rhythmic Music Reduces Connectivity within the Basal Ganglia and the Reward System.

Frontiers in neuroscience

Brodal HP, Osnes B, Specht K.
PMID: 28400717
Front Neurosci. 2017 Mar 28;11:153. doi: 10.3389/fnins.2017.00153. eCollection 2017.

Music can trigger emotional responses in a more direct way than any other stimulus. In particular, music-evoked pleasure involves brain networks that are part of the reward system. Furthermore, rhythmic music stimulates the basal ganglia and may trigger involuntary...

Positive selection on the K domain of the AGAMOUS protein in the Zingiberales suggests a mechanism for the evolution of androecial morphology.

EvoDevo

Almeida AM, Yockteng R, Otoni WC, Specht CD.
PMID: 25883781
Evodevo. 2015 Apr 08;6:7. doi: 10.1186/s13227-015-0002-x. eCollection 2015.

BACKGROUND: The ABC model of flower development describes the molecular basis for specification of floral organ identity in model eudicots such as Arabidopsis and Antirrhinum. According to this model, expression of C-class genes is linked to stamen and gynoecium...

Direct compositional analysis of AlGaAs/GaAs heterostructures by the reciprocal space segmentation of high-resolution micrographs.

Ultramicroscopy

Tillmann K, Luysberg M, Specht P, Weber ER.
PMID: 12425590
Ultramicroscopy. 2002 Nov;93(2):123-37. doi: 10.1016/s0304-3991(02)00153-5.

A detailed description of a combined reciprocal and real space technique for the mapping of layer compositions across interior interfaces from high-resolution electron micrographs is presented. The analysis is based on the reciprocal space extraction of chemically sensitive image...

The effects of alcohol intoxication on neuronal activation at different levels of cognitive load.

The open neuroimaging journal

Gundersen H, Grüner R, Specht K, Hugdahl K.
PMID: 19018317
Open Neuroimag J. 2008;2:65-72. doi: 10.2174/1874440000802010065. Epub 2008 Aug 22.

The aim of this study was to investigate how alcohol intoxication at two blood alcohol concentrations (BAC) affected neuronal activation during increasing levels of cognitive load. For this purpose we used functional magnetic resonance imaging (fMRI) together with a...
