Youth's Conceptions of Adolescence Predict Longitudinal Changes in Prefrontal Cortex Activation and Risk Taking During Adolescence

The development of cognitive control during adolescence is paralleled by changes in the function of the lateral prefrontal cortex (PFC). Using a three‐wave longitudinal neuroimaging design (N = 22, M_age = 13.08 years at Wave 1), this study examined if youth's stereotypes about teens modulate changes in their neural activation during cognitive control. Participants holding stereotypes of teens as irresponsible in the family context (i.e., ignoring family obligations) in middle school showed increases in bilateral ventrolateral PFC activation during cognitive control over the transition to high school, which was associated with increases in risk taking. These findings provide preliminary evidence that youth's conceptions of adolescence play a role in neural plasticity over this phase of development.

Post-secondary educators' professional development: Investigation of an online approach to enhancing teaching and learning

Faculty in post-secondary institutions must continually reassess, refine, and revise their teaching, yet it is a challenge for them to gain this professional development with heavy teaching responsibilities and high demands on their time. Creating Optimum Learning Environments (CREOLE) is a collaborative project between one community college and one university to develop an online training program for post-secondary education faculty on the basic principles of teaching and learning and the development of online courses. Four independent modules were developed and taught in a one semester format for educators throughout the U.S. The goal of this research was to identify the strenghts and challenges of this course; determine the changes in pedagogical practice of the participating faculty members; and to examine the resulting changes in participants' course materials to reflect learning and motivation theories, and appropriate online learning strategies. Methods included pre- and post-surveys of the participants, interviews, document analysis, and instructors' reflections. Results demonstrated high expectations from all participants, difficulty in forming a sustained learning community, continuing challenge in technological aspects, and requirement for intense instructor involvement to maintain morale.     

Hierarchy as a theme in the US college, 1880–1920

How did the undergraduate college rapidly position itself as the gateway to middle-class US employment between 1880 and 1920? This article attempts to explain one part of that process. Drawing on Weberian organisational theory, transnational intellectual history and case studies of three institutions, it identifies hierarchy as a defining aspect of both modern society and the modern workplace – one that must be comprehended and mastered by the successful ‘white collar’ worker. The author describes the turn-of-the-century transformation of the US college in the context of its increasingly hierarchical nature, as opposed to traditional explanations that focus on human capital production or the incorporation of the German research university model. Hierarchical structures in the hidden and extra-curriculum of the US college helped establish it as the pre-eminent testing ground for aspiring bureaucratic workers.     

Project DAVES: An exploratory study of social presence,e-mentoring,and vocational counseling support in community college courses

A FIPSE-funded project was designed to provide support and training to community college faculty electronically, and to develop a model to offer innovative, interactive strategies to support their students' academic and career needs. The goal of the mentoring/coaching program has been to support instructors in their online efforts, provide resources and assistance to students, and create a community of learning for all. The examination of the process was framed and guided by the concept of social presence theory. Data collected included mentors' weekly logs, researcher-generated weekly prompts, and bi-monthly focus groups. All data were analyzed qualitatively using open and axial coding. Results indicate that creating social presence may depend, in part, on having an authentic, clearly defined role. Reflections throughout the process required continuous revisions to the plans.
