Digital Citizenship in K-12: It Takes a Village

Digital citizenship encompasses a wide range of behaviors with varying degrees of risk and possible negative consequences. Lack of digital citizenship awareness and education can, and has, led to problematic, even dangerous student conduct. If our educational village does not address these issues, the digital culture establishes its own direction, potentially pushing a productive, long-term solution further out of reach. By tapping into the experience of various practitioners and experts in the field this article provides the reader with a number of suggestions that can help the professional to help their students become better digital citizens.     

Path analysis of a theoretical model of persistence in higher education among low-income black youth

Path analysis is used to examine the process of persistence in higher education among a sample of 403 low-income black youth attending a variety of institutions throughout the United States. The model explores the role of college experiences — academic and social integration and academic achievement. Although social integration was misspecified, the model expiains 32% of persistence variance when academic integration is specified prior to academic achievement. The direct effect of college grades is strongest, accounting for half of the explained variance. Academic integration is actually more important than previously believed, exerting an indirect influence through grades. Since college experiences are more important than background characteristics, persistence among low-income minority youth could be improved by program interventions.     

Supporting the Professional Development of Science Teacher Educators Through Shadowing

Despite calls for more attention to the preparation of those who prepare teachers, there have been few examples of institutionally sanctioned and structured learning opportunities created to equip faculty with the knowledge and skills necessary to become effective teacher educators. In this paper, we describe a cross-disciplinary and collaborative initiative that involves shadowing of colleagues as a means of supporting the professional learning of science teacher educators. We illustrate the unique affordance of this model and highlight our professional learning across multiple dimensions: cognitive, practical, relational, and emotional. We illustrate how shadowing can support the learning of faculty at different career stages and from different disciplinary backgrounds and entry points to teacher education through a series of vignettes of shadowing in a variety of course contexts. Finally, we offer considerations for the transferability of our model to other institutions and contexts, and how further research conducted in the context of shadowing could help deepen our understanding of the knowledge base of science teacher educators and how this knowledge is developed.

     

Validation ROI: An HPT case study from the medical device industry

Validation is both a process and a function within Company ABC. Using the human performance technology (HPT) process, interventions were prescribed to address identified performance gaps. Forecasting an annual return on investment (ROI) based on goals yielded a ROI of 168%. Data collected for the first quarter of 2009 yielded a calculated ROI of 326%. This study discusses the HPT process and what was done to achieve the results.
