Profiles of disruptive behavior across early childhood: contributions of frustration reactivity, physiological regulation, and maternal behavior

Disruptive behavior, including aggression, defiance, and temper tantrums, typically peaks in early toddlerhood and decreases by school entry; however, some children do not show this normative decline. The current study examined disruptive behavior in 318 boys and girls at 2, 4, and 5 years of age and frustration reactivity, physiological regulation, and maternal behavior in the laboratory at 2 years of age. A latent profile analysis resulted in 4 longitudinal profiles of disruptive behavior, which were differentiated by interactions between reactivity, regulation, and maternal behavior. A high profile was associated with high reactivity combined with high maternal control or low regulation combined with low maternal control. Results are discussed from a developmental psychopathology perspective.     

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk.     

Early Childhood Intervention in China from the Families’ Perspective

Research highlights the importance of early childhood intervention (ECI) for children with disabilities, and there is an increasing interest in China with respect to research on ECI. However, little research exists exploring the experience of families of young children with disabilities receiving ECI services and supports in China. The purpose of this study was to understand the ECI experiences of families of such children. A qualitative research design was used, and data were collected through interviews with six families in southwest China. This study indicated that, although China has made some progress in ECI for young children with disabilities, progress in this area is still at an early stage of development. Many issues still need to be addressed, including knowledge about typical and atypical development, early identification, professional development, increased government investment, and better implementation of existing laws.     

School–University–Community Pathways to Higher Education: Teacher Perceptions,School Culture and Partnership Building

This article provides a snapshot in time of teacher perceptions, school culture, and partnership building. We delineate how teachers perceive our partnership’s purpose and its role in transforming school culture. Second, we describe how teachers express the life expectations they have and the possibilities they hope for their students and the families involved with the partnership. Finally, we outline our thoughts on moving forward with building partnership, continuing to transform school culture, and collaborating with teachers. In conclusion, we discuss the role that partnership building can have on creating pathways to higher education for students in communities of color.     

The Right “Fit”: Exploring Science Teacher Candidates’ Approaches to Natural Selection Within a Clinical Simulation

Teachers and students struggle with the complexities surrounding the evolution of species and the process of natural selection. This article examines how science teacher candidates (STCs) engage in a clinical simulation that foregrounds two common challenges associated with natural selection—students’ understanding of “survival of the fittest” and the variation of species over time. We outline the medical education pedagogy of clinical simulations and its recent diffusion to teacher education. Then, we outline the study that situates each STC in a one-to-one interaction with a standardized student who is struggling to accurately interpret natural selection concepts. In simulation with the standardized student, each STC is challenged to recognize content misconceptions and respond with appropriate instructional strategies and accurate explanations. Findings and implications center on the STCs’ instructional practices in the simulation and the use of clinical learning environments to foster science teacher learning.     

Keeping excitement in teaching

It is imperative for those of us who teach to find ways to stay renewed and refreshed over the long term. There are at least five ways through which most of us can find new energy and excitement in our teaching. One is to focus more genuinely on our students and learn more about them as persons and as colleagues- and to listen more carefully to what they say. Another is to inform them of the important objectives of a course and allow students to assume more of the responsibility for learning. A third tip is to use a greater variety of teaching methods, particularly ones that get students more actively involved in learning. Two additional ways to add excitement to teaching are to teach new courses and to plan periodic activities away from teaching. As John Gardner has recently stated so eloquently, it is our faith in human possibilities that is the generative element in such activities as leading, teaching, and guiding students.His office offers a wide range of instructional and professional services for faculty and academic administrators in the University's thirteen schools and colleges.     

An experimental two‐way video teletraining system: Design,development and evaluation

This paper describes the design, development and evaluation of an experimental two‐way video teletraining (VTT) system consisting of two classrooms equipped with audio and video equipment and linked by a land line to enable two‐way audio/video communication. A US Navy instructor delivered instruction in person to the originating classroom and electronically to the remote classroom. Findings were that student attitudes and performance on examinations were comparable in originating and remote classrooms. Students at the remote classroom were more likely to comment on deficiencies of the VTT system and were particularly sensitive to audio problems. Instructor acceptance of the VTT system was high. Cost analysis indicated that using the VTT system was more costly than sending an instructor to a remote site but that VTT can be less cosdy than sending students to the instructor.

The research described was performed under the sponsorship of the Office of Naval Technology. The opinions expressed in this paper are those of the authors, are not official, and do not necessarily reflect the views of the Navy department.     

WhatsApp use among African international distance education (IDE) students: transferring,translating and transforming educational experiences

ABSTRACT

Much of the research on how social media is embedded into the educational practices of higher education students has a Western orientation. In concentrating on a case study of the varied ways in which African International Distance Education (IDE) students actively use social media to shape their learning experiences, we discuss an under-researched group. The paper draws on analysis of 1295 online questionnaires and 165 in-depth interviews with IDE students at UNISA, South Africa, one of the largest providers of IDE globally. WhatsApp emerges as ‘the’ key social media tool that opens up opportunities for IDE students to transfer, translate and transform their educational journey when studying ‘at a distance’. Although WhatsApp does provide a ‘space of opportunity’ for some students, this is framed through socio-technical marginalisation, itself a reflection of demographic legacies of inequality. Exploring social media practices though the case of African IDE students places these students centre stage and adds to the awareness of the multiple centres from which international education is practiced.
