Choice of Reading Comprehension Test Influences the Outcomes of Genetic Analyses

Vowel representations are particularly difficult for children to learn because most vowel phonemes can be spelled in several different ways. Children in Grades 1, 2, and 3 spelled nonwords with an ambiguous vowel and reported their spelling strategies. Analysis of the children's spellings and strategy reports revealed a shift in relying solely on phonological information to considering orthographic information for making vowel letter choices. Implications for vowel spelling development are discussed.     

El ordenador como instrumento de la mente

El discurso argumentativo escrito tiene intrínsecamente un carácter dialàgico. Esta característica se pone de manifiesto en la contraargumentación, uno de los aspectos que mayor dificultad presenta para los aprendices, tanto en la comprensión como en la producción de textos escritos. Esta dificultad se hace patente en las actividades desarrolladas en el curso de una secuencia de enseñanza y aprendizaje sobre este tipo de discurso con alumnos de los primeros niveles de enseñanza secundaria. De ello se desprende la necesidad de su enseñanza específica.     

A behaviour‐genetic analysis of orthographic learning,spelling and decoding

As part of a longitudinal twin study of literacy and language, we conducted a behaviour‐genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate analyses revealed very high genetic correlations among the variables, indicating that the same genes are involved in their aetiology. These genes are partly independent of those contributing to intelligence. A further analysis indicated that the covariation between decoding and orthographic learning is mediated by shared genes rather than by a direct causal path. The authors argue that a learning parameter, most directly assessed by orthographic learning in this study, underlies all three literacy variables. The results are also discussed in relation to Share's self‐teaching hypothesis, which may require modification.     

Genetic and environmental influences on reading and listening comprehension

We report preliminary behaviour genetic analyses of reading and listening comprehension from The Colorado Learning Disabilities Research Center. Although the twin sample with these new measures is still of limited size, we find substantial, and significant, genetic influences on individual differences in both reading and listening comprehension. In addition, word recognition and listening comprehension each accounted for significant independent genetic influences on reading comprehension. Together, they accounted for all the genetic influence on reading comprehension, indicating a largely genetic basis for the ‘simple model’ of individual differences in reading comprehension proposed by Hoover and Gough (1990) .     

A Research Review of Nurse Teachers’ Competencies

The conceptions of what constitutes nursing competence and how such competence is taught and learned are changing, due to rapid changes in in the health sector. Nurse teachers’ competencies for providing high-quality, up-to-date nursing education, are developing accordingly. This paper reviews the existing research on nurse teachers’ competencies and addresses how this research identifies, describes, and conceptualizes these competencies. A rigorous search, retrieval and appraisal process identified 25 relevant studies for inclusion in the review. A thematic synthesis was applied to the findings of the studies and subsequent themes were synthesized. The thematic synthesis of the empirical evidence resulted in the five broad themes: academic, nursing, and pedagogical competencies; attitudes; management and digital technology. However, these separate elements appeared to be highly integrated. Hence, this paper indicates that nurse teachers’ competencies may be assessed using a holistic approach, which could bring together the disparate attributes required for successful professional performance in specific situations.
