The Third Curriculum—from a Christian Perspective

According to Michel Serres, and those who support his views about education, the truly educated person is one who has been exposed to the so-called Third Curriculum. This conviction is evaluated from the vantage point of a Christian view of reality, education, and the curriculum. The author concludes that while Third-Curriculum thinking appears to be innovative and creative, its two central tenets of interdisciplinarity and dialogical thinking are not quite so new. He also concludes that the Third-Curriculum theory is still too vague, inconsistent, and programmatic to be seriously considered for implementation in schools. Its postmodern refusal to acknowledge the divine, law-subjected orderliness of creation as well as its tendency to reduce the God-given diversity in reality to only one or two aspects of reality are contrary to convictions underlying the Christian view of the curriculum and curriculum design.     

PHILOSOPHICAL-PEDAGOGICAL CRITERIA FOR ASSESSING THE EFFECTIVENESS OF A CHRISTIAN SCHOOL

An analysis of recent publications in the field of school effectiveness studies shows that virtually no contributions have been made in that knowledge domain with respect to the effectiveness of Christian schools. To address this shortcoming—while keeping the undesirability of a package approach to Christian education in mind—a philosophical-pedagogical approach to a more systematic assessment of Christian schools is offered. A number of other considerations regarding the assessment of the effectiveness of Christian schools are left for further discussion and investigation.     

The epidemiology of violent behavior in patients with a psychotic disorder: A systematic review of studies since 1980

Since the 19th century, it has been widely acknowledged that persons with a psychotic disorder are more often involved in violent crimes than those without mental problems, which is confirmed by several recent review papers and meta-analytic studies. However, the caveats and limitations of these studies have been largely neglected. In the present systematic review paper, the epidemiological studies that were published since 1980 on the link between psychosis and violent behavior were critically reviewed. Electronic databases were searched to initially identify 5756 articles. A total of 26 articles were eventually selected as they met all selection criteria. Studies were categorized according to their research design (i.e., birth cohort, community, register/record-based). Although schizophrenia and other related psychotic disorders seem to be undoubtedly associated with violent behavior (with OR's between 2 and 28), it should be kept in mind that underlying variables or risk factors (e.g., family history of violence, emotions such as anger and anxiety, impulsivity, childhood problems), the study design, and conceptual problems (i.e., definitions of violence/aggression and schizophrenia/psychosis) might be particularly relevant when interpreting the link between violence and psychosis.     

A Confirmatory Analysis of Item Reliability Trends (CAIRT): Differentiating True Score and Error Variance in the Analysis of Item Context Effects

Numerous studies have shown increasing item reliabilities as an effect of the item position in personality scales. Traditionally, these context effects are analyzed based on item-total correlations. This approach neglects that trends in item reliabilities can be caused either by an increase in true score variance or by a decrease in error variance. This article presents the Confirmatory Analysis of Item Reliability Trends (CAIRT) that allows estimating both trends separately within a structural equation modeling framework. Results of a simulation study prove the CAIRT method to provide reliable and independent parameter estimates; the power exceeds the analysis of item-total correlations. We present an empirical application to self- and peer ratings collected in an Internet-based experiment. Results show that reliability trends are caused by increasing true score variance in self-ratings and by decreasing error variance in peer ratings.     

A behavioral task for the validation of a gaze-contingent simulated scotoma

Gaze-contingent displays provide a valuable method in visual research for controlling visual input and investigating its visual and cognitive processing. Although the body of research using gaze-contingent retinal stabilization techniques has grown considerably during the last decade, only few studies have been concerned with the reliability of the specific real-time simulations applied. Using a Landolt ring discrimination task, we present a behavioral validation of gaze-contingent central scotoma simulation in healthy observers. Importantly, behavioral testing is necessary to show whether the simulation impairs foveal processing of visual information. This test becomes even more crucial when researchers are faced with null results in a task performed with the scotoma, as compared with a control condition. It must be ruled out that the lack of behavioral effects results from a type II error caused by improper implementation before conclusions about foveal contributions to the given task may be drawn. In our experiment, the scotoma effectively prevented foveal processing of the visual stimuli, leading to significantly reduced response accuracies, as compared with unimpaired vision. Moreover, the final fixation at the time of the participants’ responses was placed close to the target position in the unimpaired condition, whereas the distance to the target was enhanced with the scotoma, indicating that the observers were not able to discriminate visual target stimuli from distractors, due to the scotoma. The present work presents a validated behavioral testing method for the efficiency of gaze-contingent scotoma simulations, including code for implementation. In addition, solutions for common methodological problems are discussed.     

Increased attention for computer-tailored health communications: an event-related potential study.

The authors tested whether individually tailored health communications receive more attention from the reader than nontailored health communications in a randomized, controlled trial among student volunteers (N = 24). They used objective measures of attention allocation during the message exposure. In a between-subjects design, participants had to read tailored or nontailored nutrition education messages and at the same time had to pay attention to specific odd auditory stimuli in a sequence of frequent auditory stimuli (odd ball paradigm). The amount of attention allocation was measured by recording event-related potentials (ERPs; i.e., N100 and P300 ERPs) and reaction times. For the tailored as opposed to the nontailored group, results revealed larger amplitudes for the N100 effect, smaller amplitudes for the P300 effect, and slower reaction times. Resource allocation theory and these results suggest that those in the tailored group allocated more attention resources to the nutrition message than those in the nontailored group.
