Mutual feedback in e-portfolio assessment: an approach to the netfolio system

This paper presents an alternative application of e-portfolio in a university student assessment context. A concept based on student collaboration (called netfolio) is developed, that differs from the classical e-portfolio concept. The use of a netfolio, a network of student e-portfolios, in a virtual classroom is explained through an exploratory study. A netfolio is more than a group of e-portfolios because it offers students a better understanding of learning objectives and promotes self-revision through participation in assessment of other students' learning, as indicated through their portfolios. Class student e-portfolios are interconnected in a unique netfolio such that each student assesses their peers' work and at the same time is being assessed. This process creates a chain of co-evaluators, facilitating a mutual and progressive improvement process. Results about teachers' and students' mutual feedback are presented and the benefits of the process in terms of academic achievements are analysed.     

ISPCAN Child Abuse Screening Tool Children's Version (ICAST-C): Instrument development and multi-national pilot testing

ObjectiveTo develop a child victimization survey among a diverse group of child protection experts and examine the performance of the instrument through a set of international pilot studies.MethodsThe initial draft of the instrument was developed after input from scientists and practitioners representing 40 countries. Volunteers from the larger group of scientists participating in the Delphi review of the ICAST P and R reviewed the ICAST C by email in 2 rounds resulting in a final instrument. The ICAST C was then translated and back translated into six languages and field tested in four countries using a convenience sample of 571 children 12–17 years of age selected from schools and classrooms to which the investigators had easy access.ResultsThe final ICAST C Home has 38 items and the ICAST C Institution has 44 items. These items serve as screeners and positive endorsements are followed by queries for frequency and perpetrator. Half of respondents were boys (49%). Endorsement for various forms of victimization ranged from 0 to 51%. Many children report violence exposure (51%), physical victimization (55%), psychological victimization (66%), sexual victimization (18%), and neglect in their homes (37%) in the last year. High rates of physical victimization (57%), psychological victimization (59%), and sexual victimization (22%) were also reported in schools in the last year. Internal consistency was moderate to high (alpha between .685 and .855) and missing data low (less than 1.5% for all but one item).ConclusionsIn pilot testing, the ICAST C identifies high rates of child victimization in all domains. Rates of missing data are low, and internal consistency is moderate to high. Pilot testing demonstrated the feasibility of using child self-report as one strategy to assess child victimization.Practice implicationsThe ICAST C is a multi-national, multi-lingual, consensus-based survey instrument. It is available in six languages for international research to estimate child victimization. Assessing the prevalence of child victimization is critical in understanding the scope of the problem, setting national and local priorities, and garnering support for program and policy development aimed at child protection.     

Phonological awareness predicts activation patterns for print and speech

Using fMRI, we explored the relationship between phonological awareness (PA), a measure of metaphonological knowledge of the segmental structure of speech, and brain activation patterns during processing of print and speech in young readers from 6 to 10 years of age. Behavioral measures of PA were positively correlated with activation levels for print relative to speech tokens in superior temporal and occipito-temporal regions. Differences between print-elicited activation levels in superior temporal and inferior frontal sites were also correlated with PA measures with the direction of the correlation depending on stimulus type: positive for pronounceable pseudowords and negative for consonant strings. These results support and extend the many indications in the behavioral and neurocognitive literature that PA is a major component of skill in beginning readers and point to a developmental trajectory by which written language engages areas originally shaped by speech for learners on the path toward successful literacy acquisition.

On the damage of frescoes and stuccoes on the lower surface of historical flat suspended light vaults

In many historical and monumental Italian buildings, frescoes or stuccoes of artistic and historical value are present on the lower surface of flat light vaults, made by wooden arches, reeds and plaster. These vaults are often suspended by wooden or metallic ties to the upper bearing structures. When differential settlements of the wooden arches happen (i.e.: due to a bad working of their hangings) cracks appear on these precious surfaces. This paper experimentally and numerically investigates on this issue, pointing out which constructive parameters mainly influence the cracking behaviour of the frescoed or stuccoed lower surface, and thus providing guide lines for designing compatible conservation and retrofitting interventions.     

Learn to use and use to learn: Technology in virtual collaboration experience

This study examined how global learning teams utilized technology in a virtual collaboration to solve complex problems. The study offers an in-depth explanation of why and how the learning teams used technology to support computer-mediated communication. A model of technology application at different stages of virtual collaborative process is proposed. The model can be used to maximize potential of global teams and facilitate further integration of virtual collaboration into university curricula. Time difference and lack of nonverbal cues were identified as challenges the global teams faced. The benefits of virtual collaboration were the opportunities to: learn how to use technology in a meaningful way; practice using technology to solve problems; and broaden one's perspective by communicating with people from different cultures.
