Effect of a pilot multi-component intervention on motor performance and metabolic risks in overweight/obese youth

This study evaluated the effect of a multi-component intervention on motor performance (MP) and metabolic risk markers (MRM) in overweight/obese youth. A secondary aim was to examine whether changes in MP are associated to changes in MRM. A 3-month multi-component intervention was performed, consisting of physical exercise sessions (twice/week;1h), nutritional education sessions (once/month), and parental support (twice/week). The sample included 35 volunteers (7–13 y.o), allocated to intervention (INT, n = 17) and control (CONT, n = 18) group. Variables were measured pre (T0) and post intervention (T1). Fasting blood samples were analyzed for MRM. MP tests included the measurement of health related physical fitness components and motor coordination performance (KTK battery). To assess food intake, a 24-hour recall diary was used. GLM-ANCOVA was performed. Standardized scores were calculated for the outcome variables, and multilinear regressions were applied to analyze associations between the key variables. INT group showed improvements in MP, glycolytic and hepatic profiles. After adjustments for MVPA, SB, total intake and maturational stage, negative associations between %ΔMP and %Δglycolytic (β = -.424; 95%CI:-0.343:-0.022), and %Δhepatic scores (β = -.382 95%CI:-0.001:-0.009) were observed. The intervention produced a moderate-to-high effect on the MP and some MRM. Changes in MP were inversely associated with changes in glycolytic and hepatic markers.     

Toward a Synthesis of Cognitive Load Theory, Four-Component Instructional Design, and Self-Directed Learning

This article explores the opportunities to apply cognitive load theory and four-component instructional design to self-directed learning. Learning tasks are defined as containing three elements: learners must (a) perform the tasks, (b) assess their task performance, and (c) select future tasks for improving their performance. Principles to manage intrinsic and extraneous load for performing learning tasks, such as simple-to-complex ordering and fading-guidance strategies, are also applicable to assessing performance and selecting tasks. Moreover, principles to increase germane load, such as high variability and self-explanation prompts, are also applicable to assessment and selection. It is concluded that cognitive load theory and four-component instructional design provide a solid basis for a research program on self-directed learning.     

Success with academic English: reflections of deaf college students

The study identified social, educational, and demographic characteristics of deaf postsecondary students who demonstrated strong reading and writing skills. Questionnaire information, information from institutional databases, and in-depth personal interviews were used to identify factors and characteristics that positively influenced the attainment of strong academic literacy skills. Among the areas investigated were school experiences, reading and writing experiences, study habits and attitudes, communication preferences, personality traits, and home and family background. Results of the study generally support previous work conducted with talented hearing youth. Several primary themes emerged from the study: heavy parental involvement in early education and educational decisions, differing modes of communication but extensive family communication, early exposure to and intensive experiences with reading and writing, an enjoyment of reading, a relatively limited social life, high parental and secondary school expectations, the importance of television, and positive self-image.     

A cross-case analysis of three Native Science Field Centers

Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.     

Fostering Self-Control Development With a Designed Intervention in Physical Education: A Two-Year Class-Randomized Trial

This study evaluated whether a theory-based intervention in physical education (PE) designed to train self-control may positively impact children’s quick-temperedness and disruptiveness and whether changes in executive functions (EFs) may be a correlate or antecedent of such effects. One hundred and sixteen children aged 8–9 years participated in a 2-year intervention and completed three assessments at baseline, 6- and 18-month follow-ups in quick-temperedness and disruptiveness, hot and cool EFs. After the intervention, children in the intervention group showed lower quick-temperedness and disruptiveness and improvement in hot EF. Changes over the intervention period were moderately associated and showed marginal evidence of causal ordering, suggesting that designed PE may benefit self-control through a possible linkage to hot EF improvement.     

A cross-cultural investigation of the use of teaching styles

Teacher beliefs are a major influence on teacher actions. Because context influences beliefs, it was the purpose of this study to explore teachers' beliefs about Mosston's Spectrum of Teaching Styles from an international perspective. Over 1,400 teachers from 7 countries completed a survey related to their self-reported use of and beliefs about various teaching styles. Data suggested a shared core of reproduction teaching style use. The use of and beliefs about the production styles of teaching were more varied. Teachers' use of styles was significantly related to their beliefs about the styles.     

Towards an integrated model for developing sustainable assessment skills

One of the goals of current education is to ensure that graduates can act as independent lifelong learners. Graduates need to be able to assess their own learning and interpret assessment results. The central question in this article is how to acquire sustainable assessment skills, enabling students to assess their performance and learning throughout life, and preparing them to meet their own future learning needs. This article presents an integrated model for developing sustainable assessment skills, consisting of three components: conditions necessary for the development of sustainable assessment skills, elements of sustainable assessment and instructional methods for guiding students in the development of sustainable assessment skills. The article concludes with suggestions for future research to further develop the proposed model.     

“Split Screens” and “Spin Rooms”: Debate Modality,Post-Debate Coverage,and the New Videomalaise

This experimental research examines how different presentation modalities in presidential debates and post-debate spin influence the ability to form evaluations about candidates' character, shape perceptions of their incivility, and alter judgments of political trust and news credibility. Results indicate that these experimental factors work together to encourage character judgments, diminish perceptions of candidate civility, and reduce levels of trust in government. In addition, political talk conditioned experimental effects on perceptions of news credibility, with the adverse effects of split screen presentations concentrated among those who talked about the debate. Thus, the negative effects of “in your face” politics conveyed by the “split-screen” modality appear to be most pronounced among those primed to think about performance and those attuned to politics through interpersonal talk.
