Ethics in Neuroscience Graduate Training Programs: Views and Models from Canada

Consideration of the ethical, social, and policy implications of research has become increasingly important to scientists and scholars whose work focuses on brain and mind, but limited empirical data exist on the education in ethics available to them. We examined the current landscape of ethics training in neuroscience programs, beginning with the Canadian context specifically, to elucidate the perceived needs of mentors and trainees and offer recommendations for resource development to meet those needs. We surveyed neuroscientists at all training levels and interviewed directors of neuroscience programs and training grants. A total of 88% of survey respondents reported general interest in ethics, and 96% indicated a desire for more ethics content as it applies to brain research and clinical translation. Expert interviews revealed formal ethics education in over half of programs and in 90% of grants-based programs. Lack of time, resources, and expertise, however, are major barriers to expanding ethics content in neuroscience education. We conclude with an initial set of recommendations to address these barriers which includes the development of flexible, tailored ethics education tools, increased financial support for ethics training, and strategies for fostering collaboration between ethics experts, neuroscience program directors, and funding agencies.     

Schooling and local environmental knowledge: Do they complement or substitute each other?

Schooling and the knowledge acquired at school have been considered both a cause of loss of indigenous knowledge (because it opens pathways to the non-indigenous world and worldviews) and a potential remedy to its demise (if educational curricula is aligned with indigenous realities by giving instruction in local languages and incorporating local knowledge in school content). We test the association between academic and local environmental knowledge using data from a society of forager-horticulturalists in the Bolivian Amazon who were exposed to a partially contextualized school curriculum. We found that although schooling and academic knowledge bear a negative association with local knowledge the magnitude is low, probably because schooling was partially contextualized. Contextualized learning might help avoid that the provision of universal education comes at the cost of humanity's cultural diversity.     

Learning from the lived experiences of new language arts teachers working in diverse urban schools

This ethnographic interview study examines the factors, challenges, people and events that impacted the teaching lives of new language arts teachers. Participants taught in urban, diverse, and underserved schools. We examine our findings related to the reputation of the school, the role of the school leaders, the role of other new teachers, teacher identity, and the impact of teacher preparation programs, which emerged as clear patterns from their interviews. Data on the school culture and personnel also revealed important information on the obstacles these teachers face and supports that sustain them. This study leads to potential future research to broaden our understanding of how to attract, support, and retain new teachers in the field of language arts education.     

Correlates of Physical Activity Behavior in Rural Youth

Abstract

The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth.     

The Effects of Mastery and Competitive Conditions on Self-Assessment at Different Ages

It was hypothesized that self-evaluative accuracy will increase with age in a competitive condition, while even young children will appraise their performance quite accurately in a mastery condition. Children at ages 5, 7, and 10 working in either a match-the-standard or a competitive condition copied a drawing and then evaluated their copies. As hypothesized, competing 5-year-olds overestimated the quality of their copies, and self-assessments became less positive and better correlated with adult judgments with age. There were no age differences in self-evaluative accuracy in the mastery condition. Examination of children's explanations for their ratings and their interest in the task supported the interpretation that young children are guided by a nonnormative concept of ability, which can lead to overoptimistic perceptions of competence under competition. Older children tended to adopt normative goals and criteria for self-assessment in competition and mastery ones in the match the standard condition, and were realistic about their performance in both.     

Parenting stress, infant emotion regulation, maternal sensitivity, and the cognitive development of triplets: a model for parent and child influences in a unique ecology

To examine the development of triplets, 23 sets of triplets were matched with 23 sets of twins and 23 singletons (N=138). Maternal sensitivity was observed at newborn, 3, 6, and 12 months, and infants' cognitive and symbolic skills at 1 year. Triplets received lower maternal sensitivity across infancy and exhibited poorer cognitive competencies compared with singletons and twins. The most medically compromised triplet showed the lowest regulation, received lower maternal sensitivity, and demonstrated the weakest outcomes compared with siblings. Structural modeling charted three levels of influence on cognitive outcomes: direct, indirect, and contextual. The triplet ecology provides a context for assessing the relations among infant inborn dispositions, the rearing environment, and the role of exclusive parenting in development.     

Learning oceanography from a computer simulation compared with direct experience at sea

Considerable research has compared how students learn science from computer simulations with how they learn from “traditional” classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two college classes studying introductory oceanography. One class learned using an interactive computer simulation based on a dynamic, three‐dimensional model of physical oceanography. The other class learned by spending a day on a research ship using scientific tools and instruments to measure physical properties of the ocean directly. In classes preceding and following the simulation or field experience, students performed the same exercises regarding currents and salinity, had the same instructor presentations, and did the same homework. The study found that the field experience helped contextualize learning for students with little prior experience of the ocean while the simulation made it easier for students to connect what they learned from it to other content they learned in class. These and other findings shed light on what computer simulations can and cannot help students learn, and what concepts are best learned in the real environment. © 2005 Wiley Periodicals, Inc.

Computer-simulated laboratory explorations for middle school life,earth, and physical Science

Explorations in Middle School Science is a set of 72 computer-simulated laboratory lessons in life, earth, and physical Science for grades 6–9 developed by Jostens Learning Corporation with grants from the California State Department of Education and the National Science Foundation.³ At the heart of each lesson is a computer-simulated laboratory that actively involves students in doing science improving their: (1) understanding of science concepts by applying critical thinking to solve real problems; (2) skills in scientific processes and communications; and (3) attitudes about science. Students use on-line tools (notebook, calculator, word processor) to undertake in-depth investigations of phenomena (like motion in outer space, disease transmission, volcanic eruptions, or the structure of the atom) that would be too difficult, dangerous, or outright impossible to do in a live laboratory. Suggested extension activities lead students to hands-on investigations, away from the computer. This article presents the underlying rationale, instructional model, and process by whichExplorations was designed and developed. It also describes the general courseware structure and three lesson's in detail, as well as presenting preliminary data from the evaluation. Finally, it suggests a model for incorporating technology into the science classroom.     

At the early childhood level

Conclusion Environmental education at the early childhood level is about fostering a sense of appreciation and caring. The adult's role in the process is primarily that of sharing versus instructing: “sharing enthusiasm, curiosity, and wonder” (Dighe, 1993. p. 59). Helping young children grow in their understanding and appreciation of the natural world can greatly benefit the development of the child and has the potential for enhancing the humanearth relationship.
