Exploring the Underlying Factor Structure of the Parent Reading Belief Inventory (PRBI): Some Caveats

Although mainstream preschool programs have been in existence since the 1970s, little is known about the ways in which typical children attempt to understand what it means for a peer to have a disability. In this study, 4-year-old children without disabilities who were enrolled in a mainstream preschool class explained their peers' disabilities by referring to concepts of immaturity, accident, or adaptive equipment to account for the behavioral differences that they observed. The implications of these cognitions for children's developing attitudes and behaviors toward peers with disabilities are discussed.     

An Examination of Black Science Teacher Educators’ Experiences with Multicultural Education, Equity, and Social Justice

Diversity, multicultural education, equity, and social justice are dominant themes in cultural studies (Hall in Cultural dialogues in cultural studies. Routledge, New York, pp 261–274, 1996; Wallace 1994). Zeichner (Studying teacher education: The report of the AERA panel on research and teacher education. Lawrence Erlbaum Associates, Mahwah, pp 737–759, 2005) called for research studies of teacher educators because little research exists on teacher educators since the late 1980s. Thomson et al. (2001) identified essential elements needed in order for critical multiculturalism to be infused in teacher education programs. However, little is known about the commitment and experiences of science teacher educators infusing multicultural education, equity, and social justice into science teacher education programs. This paper examines twenty (20) Black science teacher educators’ teaching experiences as a result of their Blackness and the inclusion of multicultural education, equity, and social justice in their teaching. This qualitative case study of 20 Black science teacher educators found that some of them have attempted and stopped due to student evaluations and the need to gain promotion and tenure. Other participants were able to integrate diversity, multicultural education, equity and social justice in their courses because their colleagues were supportive. Still others continue to struggle with this infusion without the support of their colleagues, and others have stopped The investigators suggest that if science teacher educators are going to prepare science teachers for the twenty first century, then teacher candidates must be challenged to grapple with racial, ethnic, cultural, instructional, and curricular issues and what that must mean to teach science to US students in rural, urban, and suburban school contexts.     

Early Head Start Relationships: Association with Program Outcomes

Research Findings: Interpersonal relationships among staff caregivers, parents, and children have been recommended as essential aspects of early childhood intervention. This study explored the associations of these relationships with program outcomes for children and parents in 3 Early Head Start programs. A total of 71 children (8–35 months, M = 20), their parents, and 33 program caregivers participated. The results showed that caregiver–child relationships were moderately positive, secure, and interactive and improved in quality over 6 months, whereas caregiver–parent relationships were generally positive and temporally stable. Caregiver–child relationships were more positive for girls, younger children, and those in home-visiting programs. Caregiver–parent relationships were more positive when parents had higher education levels and when staff had more years of experience, had more positive work environments, or had attained a Child Development Associate credential or associate's level of education rather than a 4-year academic degree. Hierarchical linear modeling analysis suggested that the quality of the caregiver–parent relationship was a stronger predictor of both child and parent outcomes than was the quality of the caregiver–child relationship. There were also moderation effects: Stronger associations of caregiver–parent relationships with observed positive parenting were seen in parents with lower education levels and when program caregivers had higher levels of education. Practice or Policy: The results support the importance of caregiver–family relationships in early intervention programs and suggest that staff need to be prepared to build relationships with children and families in individualized ways. Limitations of this study and implications for program improvements and future research are discussed.     

Training School-Based Consultants: Some Thoughts On Grains of Sand and Building Anthills

This article reviews the major themes and issues emerging from this special issue on training school-based consultants. It is suggested that the building of anthills from individual and often seemingly disconnected grains of sand provides a useful metaphor for work in this arena. To date we have failed to establish a compelling and integrated body of empirical evidence addressing consultant training, although some excellent preliminary data have been reported. All agree that substantially more scholarly work is essential. It is proposed that the most important challenge facing us is the adoption of a unifying theoretical model to guide the organization and synthesis of our disparate "grains of sand" so that we can create meaningful and coherent "anthills" that can be of value to consultation trainers. Ecological and systems orientations are presented as the most appropriate and powerful approaches to achieve this goal. Small-N and qualitative research methodologies seem particularly well suited to this task. A number of specific research and practice ideas are suggested, although each has yet to garner sufficient empirical support and each is considered to be subsidiary to the adoption of an ecological paradigm to guide trainers and researchers in drafting a blueprint for future scientific work. As sure as worker ants can build phenomenally complex anthills from the most meager beginnings, so can we develop a scientific body of knowledge regarding consultant training. However, substantially more intellectual capital will need to be invested in this task if we are to succeed. Ultimately, it is up to us, as interested scholars, to make this happen.     

The dimensions of research in undergraduate learning

Most Australian Universities offer a selection of research-intensive pathways at the graduate level, which provides opportunities for independent inquiry and intellectual autonomy. Undergraduate students, however, are somewhat short-changed in their experience in research. They are exposed to a variety of areas and disciplines, which forms a general cluster of knowledge, but students graduate without obtaining the skills associated with research and inquiry. Digital communication networks and the ways in which information is disseminated in modern society play an important role in the way people live and learn. At the same time, younger generations are emerging with greater skills in digital literacy, which bears an impact on how knowledge is produced and information is shared. This prompts to question, are undergraduate students acquiring the generic attributes that will help them to cope with the complexities of an information-driven society? The following article is based on the premise that undergraduate students need to be empowered to construct their own knowledge as potential producers rather than mere consumers of knowledge. It provides a synthesis of cross-disciplinary perspectives and educational debates that support the argument for, and benefits of, providing research-enriched learning for undergraduate students. This article adopts a framework for the dimensions of research in undergraduate learning. The different models presented in this article aim to illustrate the various ways that research can be integrated with teaching to benefit learning.     

Learning about movies: the impact of movie release types on the nationwide box office

Major Hollywood studios typically release new movies in North America in one of the two ways, wide release or platform release. In this paper, we investigate how release form affects the demand of a new movie after it is nationally released. In particular, we focus on movies for which the platform release is pre-planned to make the problem tractable. We estimate our model using a sample of Hollywood movies that eventually received nationwide release from 1999 to 2003. Our results show that platform release shifts consumers’ perception of unobservable movie appeal through its first stage performance, which turns out to be a stronger effect than that of advertising. Meanwhile, we find that the demand for platform movies decays faster than for wide release ones after their national release. Using counterfactual analysis, we find that more than half of the platform movies which later went to national release would have earned higher profits if they had been given a wide release.     

Key block theory application for rock slope stability analysis in the foundations of medieval castles in Slovakia

This research investigates the stability of rock slopes in the foundations of selected medieval castles in Slovakia. In the first phase, static analysis of the 45 selected medieval castle rock slopes was performed, where more than 12,000 potentially unstable blocks were analyzed and the factor of safety in static condition was calculated using the key block theory implemented in the Kbslope module of PTworkshop software. Based on results of the static stability analysis, a pseudo-static analysis was performed adopting the seismic acceleration in accordance with Slovak Technical Standards – Seismic actions on structures. This was implemented by calculating the vectors of horizontal force acting upon shear failure in the direction of the slope face with a zero vertical component. When non-finite and tapered blocks were ignored, the results proved that 14% of the 12,217 blocks investigated under static conditions could be considered unstable. This number increased to 23% under pseudo-static conditions, when seismic acceleration was implemented in the stability calculations. A detailed stability assessment of the Gymes Castle located in western Slovakia was carried out with delineation of blocks prone to rock sliding and proper stabilization methods, based on joint sets orientation measurements performed on the 3D point cloud generated by laser scanner.     

Should digital files be considered a commons? Copyright infringement in the eyes of lawyers

In this article, we draw on a survey conducted with elite upcoming lawyers from all around the world to shed new light on the ethical acceptability of file sharing practices. Although file sharing is typically illegal, our findings show that lawyers overwhelmingly perceive it as an acceptable social practice. The main criterion used by lawyers to decide on the ethical acceptability of file sharing is whether or not the infringer derives any monetary benefits from it. Further, our findings show that lawyers in the public sector (including judiciary and academia) are even more tolerant of online copyright infringement than those in the private sector. Interestingly, our data suggests that this is largely the result of self-selection: lawyers who lean more on the side of broad disclosure and social sharing tend to orient themselves toward the public sector. Implications for the current state of the debate on the reform of copyright law are discussed.     

The link between student-perceived teacher talk and student enjoyment,anxiety and discursive engagement in the classroom

This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N_{7th grade} = 1,146 and N_{8th grade} = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship.
