This study describes errors and misconceptions of pre-service primary teachers, at course entry, across the mathematics curriculum. A Rasch analysis of a multiple-choice mathematics test uncovered patterns of errors in a cohort of 426 students at the beginning of their teacher education course. These errors were of varying sophistication. A map of an individual’s errors is also presented and we...

Recent research suggests the brain can learn almost any brain-computer interface (BCI) configuration; however, contrasting behavioral evidence from structural learning theory argues that previous experience facilitates, or impedes, future learning. A study by Sadtler and colleagues (Nature 512: 423-426, 2014) used BCI to demonstrate that neural network structural characteristics constrain learn...

Using the concept of CATp(0) spaces proposed by Khamsi et al. [Khamsi, M. A. and Shukri, S. A., Generalized CAT(0) spaces. Bull. Belg. Math. Soc. Simon Stevin, 24 (2017), No. 3, 417–426], we establish ∆-convergence strong convergence a perturbed variant Agarwal S-iteration process for nonexpansive mapping. Finally, from them deduce results valid α-nonexpansive mappings.

in order to investigate the effect of chemical herbicides on control of broad leaf weeds of common bean, an experiment was conducted in 2007 at yasouj with 12 treatments in a randomized complete block design with 3 replications. treatments consisted of preplant application of trifluralin herbicide at 960 g ai ha-1; postemergence application of bentazon at 1200 g ai ha-1; imaztapir at 50, 75 and...
