In the present paper, three models for teaching literature including language-based, literature as content or culture, and literature as personal growth or enrichment were evaluated. Based on these models, an integrated model was suggested. An experimental study was carried out in order to examine the effectiveness of the suggested approach…

Objective: The goal of this study was to contrast the cognitive phenotypes in boys with 47,XYY (XYY) karyotype and boys with 47,XXY karyotype [Klinefelter syndrome, (KS)], who share an extra copy of the X-Y pseudoautosomal region but differ in their dosage of strictly sex-linked genes. Methods: Neuropsychological evaluation of general cognitive…

Cumulative exposure to glucocorticoid hormones (GC) over the lifespan has been associated with cognitive impairment and may contribute to physical and cognitive degeneration in aging. The objective of the present study was to examine whether the pattern of cognitive deficits in patients with Cushing's syndrome (CS), a disorder characterized by…

The ability to comprehend trophic (nutritional) relationships and food web dynamics is an essential part of environmental literacy. However, students face severe difficulties in grasping the variety of causal patterns in food webs. We propose a curriculum for comprehending trophic relations in elementary school. The curriculum allows students to…
