Integrating mathematics,science, and technology: effects on students

Few studies have examined the student learning effects of integrating science with mathematics and technology. We compared a school that integrated mathematics, science and technology in grade 9 to a school in the same district that taught the three courses separately. The distinguishing feature of the integrating school was the reorganization of instruction in the three subjects to prepare students for seven group projects (involving a total of 25 h) that required the application of knowledge and skill that were shared by the three subjects, as well as learning outcomes that were unique to each. The study detected benefits for students in the integrated setting in terms of their ability to apply shared learning outcomes, student motivation, ability to work together and attitudes to appraisal of group work. Female students in the integrated school had a better understanding of selected science learning outcomes. Attitudes toward mid‐term exams were higher in the control school.

     

Pictures From the Sky: Propaganda Leaflet Psyop During the Korean War

This research examines illustrated propaganda leaflets designed by the military to influence the Communist enemy during the Korean War (1950–1953). The United States built a propaganda operation in an effort to counteract Communist ideology. This required military propagandists to design a leaflet campaign to reach the enemy by means of pictures and text. But skeptics demanded evidence that leaflet-based propaganda was effective; psyop staff responded by gathering documentation. Leaflet campaigns seemed to have had limited effect, however. Authors conclude that psyop staff found it challenging to design leaflets faced with an unclear mission, designers trained in irrelevant techniques of American advertising, anti-Asian bias, and weaknesses in measurements.     

Discrimination and Ethnic-Racial Socialization Among Youth Adopted From South Korea Into White American Families

The current study examined how discrimination relates to adjustment outcomes in a sample of internationally, transracially adopted Korean Americans from the Minnesota Sibling Interaction and Behavior Study (N = 456 adoptees; M_age at T1 = 14.9, M_age at T2 = 18.3, M_age at T3 = 22.3). The moderating roles of ethnic socialization and preparation for bias by parents (i.e., ethnic-racial socialization) were also examined. Results indicated that discrimination predicted higher levels of depressive and externalizing symptoms in youth who reported less preparation for bias. In those experiencing more preparation for bias, associations were not significantly different from zero. Ethnic socialization did not moderate these associations. Such findings provide important information for adoptive parents regarding how to prepare their children to cope with discrimination.     

There is an "I" in TEAM: narcissism and social loafing

We investigated narcissism as a moderator of social loafing on a physical performance task. High and low narcissistic individuals twice performed a cycling task in same-sex teams of three: once when identifiability was low; and once when identifiability was high. A significant interaction between narcissism and identifiability was revealed, F(1, 40) = 4.09, p < .05, eta2 = .09 for performance. Follow-up tests indicated that high narcissists' performance significantly increased with greater identifiability, whereas low narcissists displayed no such performance differences. Results suggested that this effect was due to an increase in narcissists' on-task effort (ratings of perceived exertion and heart rate) when they knew that their performance was to be identified.     

Mapping the core journals of the physical therapy literature

Objectives:

The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.

Method:

Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.

Results:

Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.

Conclusions:

Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.

Highlights

• More cited references were published in the last eight years studied than in any previous full decade.
• Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
• CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.

Implications

• Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
• Multiple databases are needed for comprehensive coverage of the physical therapy discipline

Teaching to trust: How a virtual archives and preservation curriculum laboratory creates a global education community?

Building virtual archives and preservation curriculum laboratories centered around born-digital and digitized records is a collaborative project currently underway between Simmons College (US) and Mid-Sweden University. In this virtual environment, issues of trust are central to the process, in terms of the both archival curriculum and the collaborative education process itself. The article describes the project, the collaboration, and offers a range of scenarios that demonstrate how the laboratories work within curriculum.     

Exploratory Mediation Analysis via Regularization

Exploratory mediation analysis refers to a class of methods used to identify a set of potential mediators of a process of interest. Despite its exploratory nature, conventional approaches are rooted in confirmatory traditions, and as such have limitations in exploratory contexts. We propose a two-stage approach called exploratory mediation analysis via regularization (XMed) to better address these concerns. We demonstrate that this approach is able to correctly identify mediators more often than conventional approaches and that its estimates are unbiased. Finally, this approach is illustrated through an empirical example examining the relationship between college acceptance and enrollment.     

The Role of Fitness Professionals in Public Health: A Review of the Literature

Kinesiology researchers have long had an interest in physical activity, fitness, and health issues and in the professional education and work practices of teachers and coaches. The professional development needs and practices of “fitness professionals,” however, have not been a major concern for researchers in the field. The purpose of this article is to provide an overview of the evidence on fitness professionals, their role in physical activity for health agendas, and the professional education and training that is available to support them. The analysis indicates that there is a mismatch between the expectations placed upon fitness professionals and the training and professional education that is available to them. It is argued that pedagogy researchers in kinesiology could usefully turn their attentions to this occupational group.
