A framework for the application of distributed broadband multimedia communication services in education and training

This paper examines the influence of multimedia communication services in education and training. After a brief introduction in multimedia communication systems and an analysis of the learning process, a framework for the application of distributed, broadband multimedia communication services in education and training is proposed. Its main elements, which are a set of requirements, a generic layered model and a list of important related matters, are then discussed in considerable detail. Finally, the application of the proposed framework in the field of telecommunications training is suggested     

Children’s Extracurricular Activities

Why do children learn in different ways: some are good students who show interest and zeal, while others are lazy and have to be taught against their will? Why do schools have over- and underachievers? Of course, there are a multitude of reasons. But almost 50 years ago it was shown using large data sets that families with high socioeconomic status are more likely to have children who are good students. Of course, there are many examples of successful students from poor families. However, they tend to be the exception to the rule. The certainty of success in school increases with rising socioeconomic status.     

Theory Competition and the Process of Change

The reasons why many educational change initiatives have little impact are often framed in terms of either a poorly designed process on the part of the change initiator, or in terms of problems with the attitudes, skills and/or knowledge of those responsible for implementation. In this paper, we seek to integrate these two perspectives more closely by focusing on their interface and the competing theories frequently held by the change initiators and implementers. This concept of theory competition is illustrated with a case of a national literacy initiative in New Zealand in which the change initiators wished to raise the achievement of low performing students through the development of “learning-centred” leadership in schools and evidence-based practice. The desired outcomes were not achieved because theories about what it means to be a successful leader in such a situation, the data needed to undertake the type of evidence-based analysis envisioned and school personnel beliefs about the target students were understood differently by those responsible for initiating the change and those responsible for implementing it.     

Play as the Leading Activity of the Preschool Period: Insights from Vygotsky, Leont'ev, and Bakhtin

Cultural-historical psychology identifies play as the leading activity in preschool development. Vygotsky's (1967, 1978) seminal work outlined two categories of leading influences: play makes a foundational contribution to the development of semiotic mediation, and it involves active appropriation of social roles and rules and other integral aspects of social organization. Leont'ev's (1981) concept of appropriation and Bakhtin's (1981) concepts of heteroglossia and ideological becoming are used to elaborate and extend Vygotsky's original work, particularly with regard to creativity in preschool play. The paper concludes with a consideration of the pedagogical implications of the cultural-historical view on play, including the use of play to cultivate understanding of the arbitrary nature of signs and the appropriation of the social roles and organizational patterns of society.     

Curriculum Design of a Flipped Classroom to Enhance Haematology Learning

A common trend in higher education is the “flipped” classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology ‘major’ class and the students’ attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56–65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %).     

A Methylome‐Wide Association Study of Trajectories of Oppositional Defiant Behaviors and Biological Overlap With Attention Deficit Hyperactivity Disorder

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).     

Indian child welfare: A community team approach to protective services

The purpose of this study is threefold: first, to describe the characteristics of child abuse and neglect on a major Indian reservation; second, to examine the impact of a community team approach to child abuse and neglect as measured by the incidence of reported abuse and neglect and admissions for emergency foster care; and third, to make recommendations for actions to close the gaps in child welfare services to Indian children living on reservations.     

Parental reactions to children's negative emotions: longitudinal relations to quality of children's social functioning

Relations between self-reported parental reactions to children's negative emotions (PNRs) and children's socially appropriate/problem behavior and negative emotionality were examined longitudinally. Evidence was consistent with the conclusion that relations between children's externalizing (but not internalizing) emotion and parental punitive reactions to children's negative emotions are bidirectional. Reports of PNRs generally were correlated with low quality of social functioning. In structural models, mother-reported problem behavior at ages 10-12 was at least marginally predicted from mother-reported problem behavior, children's regulation, and parental punitive or distress reactions. Moreover, parental distress and punitive reactions at ages 6-8 predicted reports of children's regulation at ages 8-10, and regulation predicted parental punitive reactions at ages 10-12. Father reports of problem behavior at ages 10-12 were predicted by earlier problem behavior and parental distress or punitive reactions; some of the relations between regulation and parental reactions were similar to those in the models for mother-reported problem behavior. Parental perceptions of their reactions were substantially correlated over 6 years. Some nonsupportive reactions declined in the early to mid-school years, but all increased into late childhood/early adolescence.
