The Age Factor in the Prediction of Tertary Academic Success

This study examined the predictive power of age in the academic performance of Behavioural Science students at the Darling Downs Institute of Advanced Education. Other predictor variables included were study methods, Tertiary Entrance score, personal problems, satisfaction with college, self‐concept, locus of control and flexibility of thinking. 79 students, 93% of the total population, responded to the questionnaire containing scales measuring the above variables. Results from multiple regression analyses showed that the contribution of age outweighed by far that of any other variable. The next best predictors were study methods and environment factors. The contribution of personality traits and T.E. score was minimal. A high correlation between age and study methods was also noted. A greater acceptance of older age students into Behavioural Science courses was suggested.     

Cyber Safe Curricula and Online Harassment

In this article, Heather Greenhalgh‐Spencer analyzes three examples of curricula aimed at cultivating good cyber behavior and countering online harassment. These curricula are branded as addressing civic needs, cultivating civic duty, and developing skills to help students understand and react to online threats. Here, Greenhalgh‐Spencer offers two critiques of these, and other similar, cyber safe curricula. First, current cyber safe curricula do not adequately address the ways that identity — particularly gender and sexuality — shape one's experience of online spaces and exposure to online threats. Second, current cyber safe curricula do not adequately consider nuances of how to “react” to online threats. The preponderance of cyber curricula teach students that all forms of offensive speech online should be abolished or pushed against. These curricula miss the opportunity to cultivate conversations around the tensions between the need to feel safe and the need to protect freedoms of speech.     

Long‐term effects of a psycholinguistic treatment for dyslexia

Short and long‐term effects of a treatment for dyslexia are evaluated. The treatment is based on psycholinguistic theory and assumes that dyslexia is due to poor lexico‐phonological processing of words. The treatment is computer‐based and focuses on learning to recognise and to make use of the phonological and morphological structure of Dutch words. The results of the treatment were clear improvements in reading words, reading text and spelling. Effect sizes of standardised treatment gains were large (Cohen's d>0.80 for all variables). Following the treatment, participants attained an average level of text‐reading and spelling. The attained level of reading words and reading text was found to be stable over a four‐year follow‐up period. Spelling showed a slight decline one year after the treatment, but remained stable thereafter. ¹ 1. A preliminary report of the data was presented at the World congress on dyslexia, September 1997, Thessaloniki, Greece.     

The use of generalizability theory to estimate data reliability in single‐subject observational research

Direct observation of behaviors is a data collection method customarily used in clinical and educational settings. Repeated measures and small samples are inherent characteristics of observational studies that pose challenges to the numerical estimation of reliability for observational data. In this article, we review some debates about the use of Generalizability Theory in estimating reliability of single‐subject observational data. We propose that it could be used but under a clearly stated set of conditions. The conceptualization of facets and object of measurement for a common design of observational research is elucidated under a different light. We provide two numerical examples to illustrate the ideas. Limitations of using Generalizability Theory to estimate reliability of observational data are discussed. © 2007 Wiley Periodicals, Inc.

Ethnic Identity Development and Acculturation Preferences Among Minority and Majority Youth: Norms and Contact

This article tests a longitudinal model of the antecedents and consequences of changes in identification with indigenous (Mapuche) among indigenous and nonindigenous youth in Chilean school contexts over a 6‐month period (633 nonindigenous and 270 Mapuche students, M_ages = 12.47 and 12.80 years, respectively). Results revealed that in‐group norms supporting contact and quality of intergroup contact at Time 1 predicted student's changes in Mapuche identification at Time 2, which in turn predicted changes in support for adoption of Chilean culture and maintenance of Mapuche culture at Time 2; some of the relationships between these variables were found to be moderated by age and ethnicity. Conceptual and policy implications are addressed in the Discussion .     

Effects of Videotape Mediation on the Development of Skills in Audiovisual Instruction

This study investigated whether videotape‐mediated instruction has any effect on the learning of the principles of audiovisual instruction, and on the development of practical skills. A total of 100 students were used as the sample population, 50 students (control group) receiving lectures on the selected concepts and the other 50 (experimental group) receiving both videotaped and lecture‐based instruction. Results indicated that the experimental group gained more, in general, than did the control group.     

Baseline Hypothalamic–Pituitary–Adrenal Axis and Parasympathetic Nervous System Activity Interact to Predict Executive Functions in Low‐Income Children

We examined interactions between baseline hypothalamic–pituitary–adrenal (HPA) axis and parasympathetic nervous system (PNS) activity in relation to executive functions (EF) in a sample (n = 1,005) of children in low wealth, nonurban communities at age 48 months. Salivary cortisol and respiratory sinus arrhythmia (RSA) represented baseline HPA axis and PNS activity, respectively. The interaction between RSA and cortisol predicted EF such that children with either lower RSA and lower cortisol, or higher RSA and higher cortisol had higher EF scores. These findings suggest a potential compensatory relation in which the PNS and HPA axis counterbalance each other to support cognition.
