This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R2 values of >0.85 for all variables excluding deadlift mean velocity (R2 = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance. 相似文献

There is a substantial difference in use and development of information and communication technologies and services between and within countries. Some denote this phenomenon as the digital divide.This paper addresses the competence aspect of the digital divide. It proposes municipal ICT schools as one model aimed to bridge this gap and provides an assessment of the model based on the results from a field trial in three rural municipalities in Norway. The model brings the benefits of increased competence of ICT in the communities but in addition have a potential with regard to stimulating talent development, serving as a resource for local business and offering meeting places in the communities for building social capital. The model may be successfully implemented within reasonable economic limitations but is also challenging in several ways, for instance on how teaching resources are recruited and supported.The purpose of the paper is to bring forward the discussion about how to bring all people, also those in rural areas, to be participators in the information technology age. 相似文献

Education is intimately associated with communication, and so may utilize any technology that is able to support a process that enables information to be transferred from one location to another. This paper describes the meaning of the term multi-media data base and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined. 相似文献

A large urban school district contracted with a private nonprofit educational foundation to train 126 special education resource
teachers in the last three years in an Orton-Gillingham-based program. These teachers are currently teaching learning-disabled
students in groups of 8–10 at the elementary level and 10–13 students at the secondary level. Learning-disabled students who
qualify for Special Education, either in reading or spelling, or both, are receiving the instruction.
The teachers took a Basic Introductory Class (90 hours of Advanced Academic Credit offered by the Texas Education Agency,
or six hours of graduate credit at a local university) in order to teach the program in the resource setting. A two year Advanced
Training included annual on-site observations, two half-day workshops each fall and spring, and a two-day advanced workshop
in the second summer.
First grade teachers, one selected from each of the 164 campuses, supervisors, and principals attended a 25-hour course on
“Recognizing Dyslexia: Using Multisensory Teaching and Discovery Techniques.” The first grade teachers and special education
resource teachers collaborated to provide inservice training for their colleagues.
Research, conducted by the district’s Research Department, reveals statistically significant gains in reading and spelling
ability for the learning-disabled resource students as measured by the Woodcock Reading Mastery Test-Revised, and the Test
of Written Spelling. 相似文献
