A Brief History of Information Sources in the Late 20th and Early 21st Century (A Simulation)

For hundreds of earth years prior to the end of the 20th century, people used a rudimentary and Taylor primitive technologyand as the dominant Francismeans to create, store, disseminate, and access information. Toward the end of that century and at the beginning of the Not next, new for open-ended and fldistributionexible technologies emerged, which expanded options and thus challenged the status quo. That change con-tributed to diverse social, cultural, economic, and political developments, which were greeted by many of our ancestors with enthusiasm, but also with ambiva-lence, confusion, and, occasionally, reactionary objections and turmoil. The new technologies, applications, and forms developed at that time were the precursors to the vast array of informational resources immediately and freely available to 22nd-century citizens today, resources that provide a firm foundation for pro-tecting the democratic ideals on which our society rests. Thus, this earlier time is more than an interesting period of history, for it represents an important turning point between two eras that helps us understand our informational roots and gain a new appreciation for our present circumstances

Integrating Disciplinary Literacy into Middle-School and Pre-Service Teacher Education

This case describes a summary of a formative experiment, a framework specific to educational design research, simultaneously conducted in a middle-school history classroom and a university social studies methods course. The purpose of the study was to refine an intervention to promote disciplinary literacy in history. The intervention provided middle-school students and pre-service teachers with explicit strategies to promote disciplinary literacy, while participating in a collaborative blog project engaging them in disciplinary literacy. Conclusions suggest practical consideration for implementation of disciplinary literacy into history. The case outlines the five phases of the formative experiment and briefly overviews modifications made during the intervention. Further, it offers suggestions and considerations for employing this approach to research

Using Blogs to Promote Literary Response During Professional Development

(First paragraph) The blogging has, I don’t want to say forced, but kind of made me read books that I haven’t necessarily read before, and I don’t think I would have. I’ve read lots of children’s books just through student teaching and everything, but it makes me look outside the box and maybe at other genres that I wouldn’t look at necessarily.

Time-Restricted Feeding Improves Circadian Dysfunction as well as Motor Symptoms in the Q175 Mouse Model of Huntington's Disease.

Huntington's disease (HD) patients suffer from a progressive neurodegeneration that results in cognitive, psychiatric, cardiovascular, and motor dysfunction. Disturbances in sleep/wake cycles are common among HD patients with reports of delayed sleep onset, frequent bedtime awakenings, and fatigue during the day. The heterozygous Q175 mouse model of HD has been shown to phenocopy many HD core symptoms including circadian dysfunctions. Because circadian dysfunction manifests early in the disease in both patients and mouse models, we sought to determine if early intervention that improve circadian rhythmicity can benefit HD and delay disease progression. We determined the effects of time-restricted feeding (TRF) on the Q175 mouse model. At six months of age, the animals were divided into two groups: ad libitum (ad lib) and TRF. The TRF-treated Q175 mice were exposed to a 6-h feeding/18-h fasting regimen that was designed to be aligned with the middle of the time when mice are normally active. After three months of treatment (when mice reached the early disease stage), the TRF-treated Q175 mice showed improvements in their locomotor activity rhythm and sleep awakening time. Furthermore, we found improved heart rate variability (HRV), suggesting that their autonomic nervous system dysfunction was improved. Importantly, treated Q175 mice exhibited improved motor performance compared to untreated Q175 controls, and the motor improvements were correlated with improved circadian output. Finally, we found that the expression of several HD-relevant markers was restored to WT levels in the striatum of the treated mice using NanoString gene expression assays

Obstacles to Developing Digital Literacy on the Internet in Middle School Science Instruction

Obstacles, and instructional responses to them, that emerged in two middle school science classes during a formative experiment investigating Internet Reciprocal Teaching (IRT), an instructional intervention aimed at increasing digital literacy on the Internet, are reported in this manuscript. Analysis of qualitative data revealed that IRT enabled students to explain and demonstrate appropriate strategies for locating and evaluating information on the Internet when they were asked to do so. However, students did not use these strategies or they quickly abandoned them when working independently or in small groups during inquiry projects. Data revealed three obstacles that inhibited efforts to promote consistent, independent use of strategies: the teacher\u27s role in student inquiry, the structure of inquiry projects, and students\u27 previous strategies. Results suggest notable challenges to implementing instruction that inculcates dispositions among middle school students leading to consistent, independent use of appropriate strategies for locating and evaluating information on the Internet. Implications for practitioners, policy makers, and researchers are discussed
