Steinbrink, Claudia; Groth, Katarina; Lachmann, Thomas; Riecker, Axel – Brain and Language, 2012
This fMRI study investigated phonological vs. auditory temporal processing in developmental dyslexia by means of a German vowel length discrimination paradigm (Groth, Lachmann, Riecker, Muthmann, & Steinbrink, 2011). Behavioral and fMRI data were collected from dyslexics and controls while performing same-different judgments of vowel duration in…

Van der Molen, M. J. W.; Van der Molen, M. W.; Ridderinkhof, K. R.; Hamel, B. C. J.; Curfs, L. M. G.; Ramakers, G. J. A. – Brain and Cognition, 2012
The ability to flexibly adapt to the changing demands of the environment is often reported as a core deficit in fragile X syndrome (FXS). However, the cognitive processes that determine this attentional set-shifting deficit remain elusive. The present study investigated attentional set-shifting ability in fragile X syndrome males with the…

Reynolds, Jennifer L. – ProQuest LLC, 2010
Cross country investigations have repeatedly demonstrated the disappointing math performance of students in the United States (Beatty, 1997; Ferrini-Mundy & Schmidt, 2005). The National Council of Teachers of Mathematics (2000) listed failure to rapidly recall basic facts as a common problem associated with disabilities in mathematics and…

Gordon, M. Cristina M. – ProQuest LLC, 2010
In 1989 the North Central Higher Learning Commission joined a growing movement to improve learning and classroom assessment. The movement called for a more inclusive type of assessment that involves tasks other that learning for testing. The Association of American Colleges and Universities agreed and proposed new Principles of Excellence…

Windschitl, Mark; Dvornich, Karen; Ryken, Amy E.; Tudor, Margaret; Koehler, Gary – School Science and Mathematics, 2007
Field investigations are not characterized by randomized and manipulated control group experiments; however, most school science and high-stakes tests recognize only this paradigm of investigation. Scientists in astronomy, genetics, field biology, oceanography, geology, and meteorology routinely select naturally occurring events and conditions and…

Ibanez-Orcajo, M. Teresa; Martinez-Aznar, M. Mercedes – International Journal of Science Education, 2007
Numerous investigations show that most school science teaching, in Spain and elsewhere, implicitly transmits an inductivist and very stereotyped view of science and conveys an unrealistic image of scientific work. We present some results of an investigation with fourth-level Spanish secondary education students (15 year olds) who were taught…
