Introducing Real-Time AVHRR-APT Satellite Imagery in the Classroom Environment

A low-cost (US$350) satellite receiving station was assembled and operated within a classroom environment in Gainesville (Florida) on October 2001 for acquiring satellite data directly from the Advanced Very High Resolution Radiometer (AVHRR) satellites. The simplicity of the satellite signal makes this source of real-time satellite data readily accessible to the K-16 educational community. The educational strategy of this program sought to achieve pedagogical effectiveness within the sciences, mathematics, and technology through the cultivation of applied, critical, and analytical skills. The applied hands-on laboratory and lecture experiences aimed at enabling students to visualize and integrate the various concepts presented in the classroom. The characteristics of the satellite data provide students and educators with live visible and infrared images that allow for the visualization and exploration of dynamic scientific concepts, making the AHVRR-APT system a suitable educational tool for complementing the K-16 curricula. This educational experience relied on inexpensive radio equipment for accessing satellite data through the exploration of modern space technology. When compared to Internet-based sources of AVHRR data, the virtual nature of Internet portals cannot provide students with a live satellite data acquisition experience, such as that available through a classroom-based AVHRR-APT satellite receiving station.     

Moral Reasoning about Sexually Transmitted Diseases

The purpose of this research was to investigate moral reasoning related to sexual behavior that could lead to the transmission of sexually transmitted diseases (STDs). Using hypothetical dilemmas about situations in which STDs can be transmitted, respondents were asked to explain why they believed the characters should or should not engage in risky behaviors. 40 college freshmen ( M = 18.3 years) and 32 college seniors ( M = 22.3 years) participated. Using Kohlberg's moral stage theory and Gilligan's moral orientation model, the interviews were scored for moral stage and moral orientation. Results indicated that the older age group had a significantly higher stage of moral reasoning than the younger age group when responding to dilemmas about STDs. There was a significant difference in moral stage between dilemmas, reflecting the possible effect of dilemma content on moral reasoning. The overall pattern of results shows nonsignificant gender differences in stage of moral reasoning and moral orientation. Clinical and theoretical implications of these findings for understanding the role of moral reasoning in sexual risky behavior are discussed.     

University marginal instructional costs: Implications for charges to overseas students

This paper is a summary of a study of the marginal costs of graduate instruction in a large public research university, and draws implications for financing foreign enrollments. The major finding is that because the teaching costs directly facing faculty differ from their budgetary rewards for instruction, faculty have the means to support basic research and to give aid to the most desired students, including foreigners. We also found that faculty members' marginal costs of classroom instruction are generally low. While advising is costly, it has offsetting benefits, especially in the laboratory sciences. The costs of instructing and advising foreign and domestic students are equal.     

Relationships between the constructs of a theory of curriculum implementation

Planned educational change occurs regularly throughout the world. With the enormous political change the 1994 elections brought to South Africa, a complete change in education policies was called for. The new Curriculum 2005 (C2005; Department of Education, RSA, 1997 ) embraced new teaching and learning approaches such as outcomes‐based education and learner‐centered teaching practices. To explore the progress of the implementation of C2005, a theoretical framework specifically designed to elucidate curriculum implementation in developing countries was applied to 10 case studies. The framework consists of interrelating constructs with subconstructs which impact on curriculum implementation. It enables one to look at the levels of implementation achieved both in terms of the capacity of the school and the extent to which outside support and pressure is provided. The case studies were carried out in a representative sample of schools in Mpumalanga, one of the nine South African provinces. The aim of this article is to investigate the possible interrelationships of the constructs and the subconstructs. Some predictable relationships emerged from the data while other expected relationships failed to materialize. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 313–336, 2005     

Sensory Processing in Rhesus Monkeys: Developmental Continuity,Prenatal Treatment,and Genetic Influences

Neonatal sensory processing (tactile and vestibular function) was tested in 78 rhesus macaques from two experiments. At ages 4–5 years, striatal dopamine D₂ receptor binding was examined using positron emission tomography. At ages 5–7 years, adult sensory processing was assessed. Findings were: (a) prenatal stress exposure yielded less optimal neonatal sensory processing; (b) animals carrying the short rh5‐HTTLPR allele had less optimal neonatal sensory scores than monkeys homozygous for the long allele; (c) neonatal sensory processing was significantly related to striatal D₂ receptor binding for carriers of the short allele, but not for animals homozygous for the long allele; and (d) there was moderate developmental continuity in sensory processing from the neonatal period to adulthood.     

Global Consultation Processes: Lessons Learned from Refugee Teacher Consultation Research in Malaysia

ABSTRACT

The process of global consultation has received little attention despite its potential for promoting international mutual understanding with marginalized communities. This article details theory, entry, implementation, and evaluation processes for global consultation research, including lessons learned from our refugee teacher intervention. The first half of the article addresses the entry process, culture-specific strengths, and challenges that can be faced in global consultation, including our experience with a lack of formal regulatory oversight of refugee education. The second half of the article details feedback collected from consultants, peer trainers, and peer trainees indicating which training content was most valuable; how some Burmese refugee teachers strive for a more student-centered, “free” classroom for their refugee students; and, finally, the toll that intense refugee teacher consultation took on the consultants.     

Developing cultural humility through experiential learning: How home visits transform early childhood preservice educators’ attitudes for engaging families

Research calls for teacher education to prepare early childhood educators for the needs of diverse and marginalized young children and their families in the U.S. With an increasing cultural divide between teachers and students, some early childhood educators may demonstrate limited understanding for how diverse cultural, linguistic, racial, and socioeconomic backgrounds inform the daily functions of families of young children. In this article, we examine how the use of experiential learning vis-à-vis conducting a home visit with a family from a diverse and marginalized background can shape early childhood preservice teachers’ (PST) development of cultural humility, an important component of cultural competence. During this experiential learning, PSTs engaged in critically reflective practices to uncover and challenge their implicit biases. While discovering the strengths and challenges among their home visit families, PSTs also learned what they had in common with the families. PSTs noted how the home visit process informed their work as future early childhood educators.     

Sensory processing disorder in a primate model: evidence from a longitudinal study of prenatal alcohol and prenatal stress effects

Disrupted sensory processing, characterized by over- or underresponsiveness to environmental stimuli, has been reported in children with a variety of developmental disabilities. This study examined the effects of prenatal stress and moderate-level prenatal alcohol exposure on tactile sensitivity and its relationship to striatal dopamine system function in thirty-eight 5- to 7-year-old rhesus monkeys. The monkeys were from four experimental conditions: (a) prenatal alcohol exposed, (b) prenatal stress, (c) prenatal alcohol exposed + prenatal stress, and (d) sucrose controls. Increased D(2) receptor binding in the striatum, evaluated using positron emission tomography neuroimaging, was related to increased withdrawal (aversion) responses to repetitive tactile stimuli and reduced habituation across trials. Moreover, prenatal stress significantly increased overall withdrawal responses to repetitive tactile stimulation compared to no prenatal stress.     

Refugee-Teacher-Train-Refugee-Teacher Intervention Research in Malaysia: Promoting Classroom Management and Teacher Self-Care

ABSTRACT

Given the current refugee crisis, the development of sustainable postconflict refugee education systems and supports is essential. The present study reports Resilient Refugee Education (RRE) intervention effects on refugee teacher confidence and knowledge of classroom management, in addition to refugee teacher self-care in Malaysia. We compared effects on (a) peer trainers, who were refugee teachers trained by consultants (n = 38), and (b) peer trainees, who were refugee teachers trained by peer trainers (n = 78). The sample included teachers who were refugees (n = 97; mean age = 30; 78% Burmese) and nonrefugees (n = 19; mean age = 48; 44% Chinese-Malaysian). Significant effects on teacher knowledge, confidence, and self-care were found for both trainers and trainees, including interactions with gender and education. Implications for sustainable promotion of the emotional context in refugee education are discussed.
