Stars and Stripes is a unique newspaper with a distinctive mission, ownership and journalistic staff unlike any in the USA. Despite its parentage in the US Department of Defense, directives give the newspaper editorial independence. Still, military commanders and Pentagon overseers have challenged and interfered with those rights since the newspaper's First World War beginnings in Europe. This study examines the published accounts of that struggle, finding that despite the newspaper's journalistic successes, the military has periodically engaged in control and interference, particularly because of the newspaper's logistical dependence upon the Department of Defense. Stars and Stripes' achievements have largely been dependent upon having the support of various military commanders in charge of US overseas military forces, having military editors or publishers who were resolute against military intrusion, or having the involvement of Congressional oversight committees and other news media willing to expose military news management at the newspaper.  相似文献

In the past decade, research and theoretical advancements in both cognitive science and instructional technology have led to updates in instructional design theory. In this article, we review two areas in which the updates make important contributions: information analysis for higher-order cognition, and instructional strategies to improve acquisition of such higher-order processes. From our reviews of the literature, we propose procedures for conducting a contextual module analysis and designing integrated instructional strategies. An additional purpose of the article is to demonstrate the need for researchers in educational technology to lead in the discovery of theories contributing to acquisition of higher-order cognition.  相似文献

The American Bar Association requires that all law students receive “substantial instruction” in legal research. This article discusses a unique legal research program that meets this requirement by focusing on experiential learning. Two components of experiential learning, context and connections, are explained pedagogically and specifically as to legal research curriculum.  相似文献

Advisory committees of mathematics consider abstract algebra as an essential component of the mathematical preparation of secondary teachers, yet preservice teachers find it challenging to connect the topics addressed in this advanced course with the high school algebra they must someday teach. This study analyzed the mathematical content knowledge that developed in preservice teachers during a semester course in abstract algebra utilizing Lerman's “person-in-practice-in-person” lens. This unit of analysis provided insights into the situated nature of the algebra learned by illuminating how the goals of the instructor and preservice teachers impacted the community of practice created in the university classroom and how participating in that community impacted the preservice teachers' mathematical identities.  相似文献

ABSTRACT

This article presents a large-scale evaluation study of over 3000 9–14-year-old students who participated in an engineering workshop during their school fieldtrips. Student perceptions right before and after, as well as two weeks after the workshop were captured and examined. Before the workshop, younger students and boys, generally exhibited higher interest, higher self-efficacy, and less negative stereotypes for engineering than their counterparts. Also, Caucasian students had higher self-efficacy and lower negative stereotypes than Hispanic students. Students’ interest, self-efficacy, negative stereotype, and utility perceptions of engineering were significantly improved right after the workshop, and improved perceptions were maintained at the delayed-post (follow-up) survey. The results indicate that fieldtrips can significantly improve students’ perceptions towards engineering and improved perceptions are not limited to the workshop day, but persist afterwards. The gender and ethnic differences in engineering perceptions in the youngest age group indicate that outreach interventions should begin in elementary school.  相似文献

Mobile phones and other wireless devices that produce electromagnetic fields (EMF) and pulsed radiofrequency radiation (RFR) are widely documented to cause potentially harmful health impacts that can be detrimental to young people. New epigenetic studies are profiled in this review to account for some neurodevelopmental and neurobehavioral changes due to exposure to wireless technologies. Symptoms of retarded memory, learning, cognition, attention, and behavioral problems have been reported in numerous studies and are similarly manifested in autism and attention deficit hyperactivity disorders, as a result of EMF and RFR exposures where both epigenetic drivers and genetic (DNA) damage are likely contributors. Technology benefits can be realized by adopting wired devices for education to avoid health risk and promote academic achievement.  相似文献

ABSTRACT

Studies show that early engagement with mathematics leads to increased math achievement later in life. Yet, early childhood teachers do not regard mathematics as critical to young learners’ development and lack confidence with helping children learn mathematics. Early childhood teacher comfort and engagement with mathematics is a critical element to promoting intentional math instruction. Research was conducted to examine the effects of an innovative professional development program for Head Start preschool teachers with the goal of increasing pedagogical content knowledge and confidence in teaching mathematics. The findings in this article focus on classroom observations that concentrated on teacher engagement with mathematics.  相似文献
