Effectiveness of Multimedia Pedagogical Agents Predicted by Diverse Theories: a Meta-Analysis

Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents’ characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse theories predicting the effects of these agents’ characteristics. We tested predictions of cognitive load theory, cognitive theory of multimedia learning, computers are social actors, social agency theory, uncanny valley, and the action observation network. Our meta-analysis of 32 effect sizes (N?=?2104) revealed a small overall effect (g+?=?0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents. As predicted by the redundancy effect of cognitive load theory and the coherence principle of cognitive theory of multimedia learning, 2D agents (g+?=?0.38) tended to be more effective than 3D agents (g+?=?0.11). As predicted by the computers are social actors hypothesis, most of the agents’ characteristics, including nonverbal communication, motion, and voice, appeared not to moderate their effectiveness. We conclude that multimedia pedagogical agents help learning through multimedia, and that students may be able to learn similarly from different types of agents.

     

The preparation of pre-service student teachers’ competence to work in schools

Competence to work in schools is an important dimension of professional competence, although it is often a neglected dimension of teacher development. This article reports a qualitative study that examined student teachers’ learning experiences in initial teacher education (ITE) in relation to competence to work in schools. In-depth interviews were conducted with 12 student teachers on an undergraduate ITE programme in Hong Kong. The findings of the study show that competence to work in schools is characterised by student teachers’ deep contextualised learning. In addition, it offers a deeper understanding of this competence in the ITE context by identifying its three facets, namely understanding of the micro-political realities of schools, social capital building and social strategies. The study provides insights for ITE and schools to support student teachers’ development of their competence to work in schools, including the design of ITE curricula, ITE processes and co-curricular activities in undergraduate studies. Moreover, it suggests the importance of developing schools as growth-fostering and positive micro-political sites for ITE fieldwork and teacher induction.     

Meaning of life as a protective factor of positive affect in acculturation: A resilience framework and a cross-cultural comparison

Although research has demonstrated a strong linkage between meaning of life and positive emotion, few studies have examined this association in the context of acculturation. The purpose of this study was to investigate the predictive effects of meaning of life and acculturative stressor on positive affect in a sample of Chinese international students in Australia and Hong Kong, and to compare these effects between the two groups. Four hundred mainland Chinese postgraduate students at six universities in Hong Kong and 227 Chinese international students at the University of Melbourne in Australia completed a questionnaire that included measures of acculturative stressor, meaning of life, positive affect, and demographic information. The analyses revealed that (1) meaning of life had a strong positive contribution to predict positive affect in acculturation, and acculturative stress had a negative impact on positive affect within both samples; (2) social interaction had a significant negative predictive effect on positive affect in both samples, and academic work served as a significant negative predictor of positive affect in the Hong Kong sample; and (3) meaning of life was found to mediate the relationship between acculturative stress and positive affect in both samples. The theoretical and practical implications of the study are discussed.     

Making News Today: a tool for adoption of ethics principles using technology‐supported television journalism

There are movements internationally towards curricula that incorporate values and citizenship education. In Australia, this movement has been illustrated with the adoption of a national curriculum in values education. This has arisen from the perceived need for citizens to hold values around the rights and responsibilities of functioning within a democracy. The Making News Today programme has been designed to develop a range of literacies enabling learners, for example, to read the media beyond the interests of the elite. The programme incorporates a journalistic process for television news production for middle school students using laptop and handheld video technologies, with embedded ethics and values education. The article reports on an analysis of the implementation of this programme with middle school students in Australia with reference to student adoption of ethical stances in the journalistic process and the implications for the use of this project in developing ethics, values and citizenship as part of the curriculum process.     

A Comprehensive Analysis of High School Genetics Standards: Are States Keeping Pace with Modern Genetics?

Science education in the United States will increasingly be driven by testing and accountability requirements, such as those mandated by the No Child Left Behind Act, which rely heavily on learning outcomes, or "standards," that are currently developed on a state-by-state basis. Those standards, in turn, drive curriculum and instruction. Given the importance of standards to teaching and learning, we investigated the quality of life sciences/biology standards with respect to genetics for all 50 states and the District of Columbia, using core concepts developed by the American Society of Human Genetics as normative benchmarks. Our results indicate that the states' genetics standards, in general, are poor, with more than 85% of the states receiving overall scores of Inadequate. In particular, the standards in virtually every state have failed to keep pace with changes in the discipline as it has become genomic in scope, omitting concepts related to genetic complexity, the importance of environment to phenotypic variation, differential gene expression, and the differences between inherited and somatic genetic disease. Clearer, more comprehensive genetics standards are likely to benefit genetics instruction and learning, help prepare future genetics researchers, and contribute to the genetic literacy of the U.S. citizenry.     

Parental perspectives and challenges in inclusive education in Singapore

Relatively little work has focused on inclusive education in Singapore. This study examines the experiences and perceptions of parents whose children with disabilities are attending mainstream secondary schools in Singapore. Data was drawn from interviews with 13 parents of children with mild disabilities. Our findings reveal that parental perspective on inclusive education in Singapore is not only about classroom support but also reflects a deeper concern about whether their children with disabilities will emerge from school as contributing individuals in society. While parents strive to effectively include their children with disabilities in mainstream classrooms, there were dichotomies in their (1) understanding of disabilities, (2) expectations of school support, and (3) expectations for their child with disabilities. Given that academic and social prowess is a critical prerequisite to have a shot at entering the meritocratic Singapore society, the tension parents experience is to gauge a reasonable amount of pressure to exert on their children, the school and themselves as they assert their children's educational entitlements within an imperfect but evolving state of inclusion.     

Characteristics of project management at institutions sponsoring National Library of Medicine MedlinePlus Go Local

Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

• Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
• An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
• Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
• Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

• NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
• NLM should emphasize continuity plans to address project coordinator turnover.
• NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

     

Departmentalized,Self-Contained,or Somewhere in Between: Understanding Elementary Grade-Level Organizational Decision-Making

Recent trends indicate a move away from self-contained classrooms and toward content-focused departmentalization in elementary schools. This study takes a snapshot of the existing organizational structures used in elementary schools in one district and explores administrators’ beliefs and practices regarding this phenomenon. Our findings suggest administrators base their decisions to organize grade levels on various factors, including their own experiences, contextual dynamics, and personal perceptions of outcomes for students and teachers.
