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

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

The purpose of this study was to improve understanding of the link between self-presentational concerns and competitive anxiety. Specifically, we examined (a) associations among self-presentational concerns and competitive state anxiety dimensional symptom responses using the modified Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Vealey, & Burton, 1990) and (b) whether self-presentational concerns mediate trait-state anxiety relationships. In addressing these matters, we also examined the factor structure and composition of the Self-Presentation in Sport Questionnaire (SPSQ; Wilson & Eklund, 1998). Results showed that self-presentational concerns were positively associated with intensity and frequency dimensional symptoms and negatively associated with direction symptoms. Results also showed that self-presentational concerns demonstrated consistently higher associations with the cognitive component and the intensity symptom of the CSAI-2 state measures. Results showed no support for the notion that self-presentational concerns mediate the trait-state anxiety relationship. When examining the factor structure and composition of the SPSQ, the results from two independent athlete samples support the tenability of an abbreviated 21-item four-factor model. Thus the newly constituted scale is recommended for measuring self-presentational concerns in sport. 相似文献
