Children’s writing of argumentative texts: Effects of indirect instruction

This study reports on grade 4 children’s (Ss) knowledge of constraints and characteristics of persuasive written requests (RQ).

1. All Ss wrote a first RQ asking money to improve their computer lab.
2. Experimental (E) and control (C) Ss evaluated 4 different RQ.
3. selected and ordered, out of 30 scrambled sentences, those appropriate for a “good” RQ.
4. A week later, E Ss had a collective “training discussion” on requests.
5. A week later, E and C Ss wrote a second RQ asking money for their science lab.

Results pertaining to different aspects of the produced RQ showed that the training did have some effects but both groups improved in their II RQ. The results were interpreted as suggesting that both groups actually learned what an appropriate request is by carefully evaluating the 4 requests and by constructing a request from a sentence list.

Effective measures to foster girls’ interest in secondary computer science education

The interest of girls in computing drops early during primary and secondary education, with minimal recovery in later education stages. In combination with the growing shortage of qualified computer science personnel, this is becoming a major issue, and also a target of numerous studies that examine measures, interventions, and strategies to boost girls’ commitment to computing. Yet, the results of existing studies are difficult to navigate, and hence are being very rarely employed in classrooms. In this paper, we summarize the existing body of knowledge on the effective interventions to recruit and retain girls in computer science education, intending to equip educators with a comprehensive and easy-to-navigate map of interventions recommended in the existing literature. To this end, we perform an aggregated umbrella literature review of 11 existing reviews on the topic, together accumulating joined knowledge from over 800 publications, and formulate the findings in a map of 22 concrete interventions structured in six groups according to their phase and purpose.

     

Effects of wax-based anti-graffiti on copper patina composition and dissolution during four years of outdoor urban exposure

The protection against graffiti has become a serious problem in most cities. Unfortunately such form of vandalism does not save the cultural heritage. The use of anti-graffiti coatings is a common treatment that can also temporary protect the surface from degradation due to interactions with the environment. Aspects that have not yet been sufficiently investigated from a metal artefact perspective are whether the presence of the anti-graffiti coating will influence the patina composition and reduce the degree of patina dissolution. Long-term (four years) effects of wax-based anti-graffiti coatings on bare copper sheet and pre-patinated copper exposed to urban atmospheric conditions are presented and discussed in terms of changes in patina dissolution rates, barrier properties and composition. The investigation is based on a multi-analytical approach combining chemical analysis, analytical and electrochemical tools (stereomicroscopy, FTIR, XRD, SEM/EDS, AAS, EIS, colorimetric measurements). Results are believed to provide important information related to the long-term applicability of such coatings to preserve the Cultural Heritage.     

A health education outreach partnership between an academic medical library and public library: lessons learned before and during a pandemic

Background:Public libraries serve as community centers for accessing free, trustworthy health information. As such, they provide an ideal setting to teach the local community about health and health literacy, particularly during public health crises like the COVID-19 pandemic. Since 2018, an outreach partnership between an academic medical library and public library has developed, delivered, and continuously evaluated a health education program targeting public library users.Case Presentation:Health education activities were integrated into three existing public library programs: adult workshops, child and family programming, and circulating family activity kits. Prior to COVID-19, events were held at the public library, which then pivoted online during the pandemic. An interprofessional team approach combined the expertise of academic medical and public librarians, medical school faculty and staff, and medical students in developing the educational programs. Twelve in-person and five virtual programs were offered, and five circulating health education family kits were launched. Activities were assessed using program evaluation surveys of the adult and children''s programs and circulation statistics of the kits.Conclusions:This case report showcases the lessons learned from implementing a longitudinal outreach partnership between an academic medical library and public library before and during the COVID-19 pandemic. The interprofessional team approach and flexibility in program design and delivery in both the in-person and virtual environments proved critical to the success of the partnership. This partnership could serve as a model for other libraries interested in pursuing interprofessional collaborations in educating local communities on healthy behavior and health information–seeking practices.     

Writing and conceptual change. What changes?

This study was focused on elementary school students'processes of scientific understanding within aclassroom environment characterized as a community ofdiscourse. In particular, it explored the role ofwritten discourse both on the plane of knowledgedevelopment and the conceptualization and evaluationof the writing activity itself. The purposes of thestudy were: (a) to see whether students could use writingas a means to express and compare ideas, reason andreflect on them in the process of scientificunderstanding; (b) to see whether writing in the serviceof learning facilitated the understanding of the newtopic through conceptual change; (c) to see whetherwriting affected the conceptualization of the writingactivity itself. Thirty-six fourth graders divided intwo groups, experimental (writing) and control(no-writing), were involved in the implementation ofcurriculum units on plants, whose target concept wasphotosynthesis. The findings show that in theexperimental group the students reached a betterconceptual understanding of the target concept andmore advanced metaconceptual awareness of the changesin their own knowledge structures. Moreover, theconceptualization of the writing activity seemed tochange as well to some extent as writing in aconceptual change process affected the ways learnersviewed some functions of it.
