How adolescents navigate Wikipedia to answer questions / ¿Cómo navegan los adolescentes en Wikipedia para contestar preguntas?

Abstract

In one experiment, we explored how high school students use hyperlink relevance cues while they navigate to answer questions from hypertexts. Current evidence has shown that students may navigate by either performing a deep semantic analysis of the relationship between the question and the existing hyperlinks, or by matching words in the question to words in the hyperlink labels. We focused on how students combine both cues during navigation, and how comprehension skills relate to the use of such cues. Our study revealed that 14 year old students (N = 53) selected hyperlinks by relying to a similar degree on both word matching and semantic overlap. Furthermore, when there was a conflict between an irrelevant link cued via word matching and a relevant link only cued through semantic overlap, students’ comprehension skills facilitated their initial selection of an informative relevant link. To conclude, we discuss the implications of these results for current models of hypertext navigation.     

Self-perception,self-esteem and life satisfaction in adopted and non-adopted children and adolescents / Autopercepción,autoestima y satisfacción vital en niños y adolescentes adoptados y no adoptados

This paper analyses whether the specific challenges of adolescence and adoption may affect the self-assessment of adopted adolescents. A total of 618 children and adolescents from Andalusia (southern Spain) between eight and 16 years of age (105 adopted and 513 non-adopted) participated in this study. For comparison purposes, different groups of non-adopted children (current classmates, children in residential care and children who have grown up with their biological families in socially disadvantaged areas) also participated. The Self-Perception Profile for Adolescents, the Rosenberg Self-Esteem Scale (RSE) and the Students’ Life Satisfaction Scale (SLSS) were utilized. The results reflect positive self-assessments on average at the beginning and during adolescence. There is a decline in self-perception, self-esteem and life satisfaction at around 11 or 12 years, with a slight recovery beginning at the age of 14. This trend occurs in adopted and non-adopted children and adolescents. Adopted children present self-assessments similar to children who live with their biological family. Children in residential care exhibit self-perception, self-esteem and life satisfaction that is well below the rest.
