Social inference skills in learning disabled and nondisabled children

The study examined the performance of 30 learning disabled and 30 nondisabled children in grades 1 through 7 on the Test of Social Inference (TSI). Results indicated that disabled students obtained lower TSI total scores that did nondisabled students: they also performed relatively lower on TSI items requiring more verbal expression. While no difference was found between the groups on the Motor-Free Visual Perception Test (MVPT), the relationship between MVPT and TSI scores was shown to be significant within the disabled group only. Furthermore, this group made more perceptual-type errors on the TSI. Findings are discussed in relation to previous research suggesting a link between visual perception and/or language fluency and social inference skills among learning disabled children.     

Transport and deposition of airborne pollutants in exhibition areas located in historical buildings–study in Wawel Castle Museum in Cracow,Poland

Historical buildings and castles that have been turned nowadays into museums, as an exhibition area for precious cultural heritage (CH) items, need more attention since they are CH objects by themselves. Moreover, the preservation techniques require often, significant interventions; however such changes are not always possible or are very limited. The aim of the present study was to investigate the influence of outdoor air pollution on the composition of particulate matter and gases inside the museum of Wawel Castle in Cracow, Poland. During this study a combination of micro and trace analysis techniques were applied, including energy dispersive X-ray fluorescence (EDXRF) and electron probe microanalysis (EPMA). An intensive transport of air pollutants coupled with accumulation of the particles inside the museum was noticed (considerably higher in winter than summer). A high content of carbon and organic matter agglomerated with inorganic particles was determined. Those particles are of special concern because of their adhesive properties and reactivity. It was also noted that the conditions inside the museum favour the reaction of the particles with gaseous pollutants. It was especially the case for nitrate particles.

Developing and acting upon one's conception of the nature of science: A follow‐up study

This study aimed to delineate the factors mediating the translation of preservice teachers' conceptions of the nature of science into instructional planning and classroom practice. Additionally, the study assessed the influence of temporally separating teaching preservice teachers about the nature of science and teaching them how to address it instructionally. This latter intervention was based on the results of a previous investigation. Prior to student teaching, the 13 participants responded to an open‐ended questionnaire designed to assess conceptions of the nature of science. Throughout student teaching, daily lesson plans, classroom videotapes, portfolios, and supervisors' weekly clinical observation notes were collected and searched for explicit instances of nature of science planning and/or instruction. Following student teaching, participants were interviewed to validate their responses to the open‐ended questionnaire, identify factors that mediate the translation of their conceptions of the nature of science into classroom teaching, and explicate their pedagogical preferences for teaching the nature of science. Participants possessed adequate understanding of several aspects of the nature of science and, contrary to the results of the earlier investigation, most did not conflate the nature of science with science processes. Furthermore, several participants explicitly addressed some aspects of the nature of science during classroom instruction. Participants, however, failed to include the nature of science among their instructional objectives and did not make a concerted effort to assess student understandings. © 2000 John Wiley & Sons, Inc.

Reading Anxiety in L1: Reviewing the Concept

Elevated levels of anxiety have been associated with students’ poor academic performance. Research on domain-specific anxiety patterns in reading has demonstrated that reading anxiety is associated with, yet distinctive from, general anxiety. Reading anxiety is an unpleasant emotional reaction experienced by students when reading; it is a specific phobia, situational type. Although reading anxiety has been largely studied in the context of second language acquisition (L2), there is a lack of new research on reading anxiety related to first language learning (L1). In this article we investigate the concept of reading anxiety, as well as the instruments that have been used to evaluate it. Finally, we present the repercussions of reading anxiety upon students’ reading performance and discuss the importance of evaluating reading anxiety as a route to better understandings of reading disabilities.     

Designing for problem-based learning in a collaborative STEM lab: A case study

Higher education institutions are using virtual telepresence systems to engage in collaborative course redesign and research projects. These systems hold promise and challenge for inter-institutional work in STEM areas. This paper describes a case study involving two universities in the 4-VA consortium, and the redesign of a shared STEM lab. The purpose of this study was to investigate pedagogical needs across related content areas, and to use findings to make informed lab design recommendations that support beliefs and best practices involving knowledge acquisition. The researchers used several data collection points involving human subjects, site visits and technology testing and evaluation. Results emphasize the need for remote presence in the student-centered and distributed space. Design recommendations are organized into the following categories: general lab space, projection and display, storage, cable management and outlets, videoconferencing, use and management of the lab, computing and mobile devices, software, and training. Further research is proposed.     

Mandated state-level open government training programs

Although every state in the country has recognized the importance of government transparency by enacting open government provisions, few of those statutes require training programs to encourage records custodians to comply with the law. Ten states mandate training in how to legally respond to public records requests, and some mandates are stronger than others. Using the qualitative research methods of legal statutory analysis, interviews, and content analysis, this paper explores how those states comply with the training mandates. The paper evaluates trainers' pedagogical goals, their opinions of the process, and their perceptions of the people they train. It concludes with suggestions for how states can develop open government training programs.
