ABSTRACT The aim of this article is to show the result of research into the situation of the integration of visually impaired children in Seville (Spain). This work refers to both classroom and peripatetic teachers’ perspectives. We have worked with four peripatetic teachers and nine classroom teachers from Seville. We have used qualitative methodological procedures for data collection and analysis. The results indicate that classroom organization is the most important problem in integration, and within this problem the relationship between classroom and peripatetic teachers becomes a fundamental issue. 相似文献

This paper investigates the relationship between ability to detect changes in prosody and reading performance in Spanish. Participants were children aged 7–8 years. Their tasks consisted of reading words, reading non‐words, stressing non‐words and reproducing sequences of two, three or four non‐words by pressing the corresponding keys on the computer keyboard. Non‐word sequences were constructed with minimal non‐word pairs differing in a single phoneme (/kúpi/ ‐ /kúti/) or in the stress pattern (/mípa/ ‐ /mipá/). Results showed that performance on phoneme contrast sequences (e.g. /kúpi/ ‐ /kúti/) predicted word reading. In contrast, performance on stress contrast sequences (e.g. /mípa/ ‐ /mipá/) predicted non‐word reading, but only when two‐non‐word sequences were analysed. This suggests that stress sensitivity may be one of the factors related to reading fluency as most errors at reading non‐words consisted of false starts and pauses between syllables. Results also showed that stress sensitivity (scored in two non‐word sequences) predicted stress assignment, and that knowledge of stress rules predicted both word and non‐word reading. This suggests that stress sensitivity may help in learning stress rules, and that knowledge of stress rules is relevant for reading. 相似文献

This study examined the effect of (a) high- and low-level questions and (b) reading the text before the questions asked on performance, delayed text recall, and deep text comprehension, as well as on specific text-inspection patterns. Participants were 37 undergraduate students who answered either high- or low-level questions using the software Read&Answer to read and answer questions on the computer screen. Additionally, half of the sample read first a text and then answered the questions (reading-first condition), whereas the other half answered the questions without having read the text in advance (no-reading-first condition). All participants had the text available to search for the answer. Results indicated that high-level questions facilitated deep comprehension but not immediate performance or delayed recall of text, independently of the reading condition, and that high- and low-level questions differentially affected text-inspection patterns. 相似文献

This paper presents a solution to the problem of global exact output tracking for uncertain MIMO (multiple-input–multiple-output) linear plants with non-uniform arbitrary relative degree using output feedback sliding mode control. The key idea to overcome the relative degree obstacle is to generalize our previous hybrid estimation scheme to a multivariable version by combining, through switching, a standard linear lead filter with a non-linear one based on robust exact differentiators, achieving uniform global exponential practical stability and exact tracking. 相似文献

A general input-to-state stability (ISS)-type small-gain result is presented. It specializes to a small-gain theorem for ISS operators, and it also recovers the classical statement for ISS systems in state-space form. In addition, we highlight applications to incrementally stable systems, detectable systems, and to interconnections of stable systems. 相似文献

The purpose of this study was to evaluate the effects of whole-body vibration (WBV) on the muscle recruitment of selected upper and lower body muscles during the baseball swing. Participants were recreationally trained males (n = 16, 22 +/- 2 years, 181.4 +/- 7.4 cm, 84.7 +/- 9.0 kg), with previous baseball experience. Subjects participated in three randomized sessions on separate days, consisting of three sets of five swings offa hitting tee. Exercises (upper and lower body dynamic and static movements) with or without WBVexposure were performed between swing sets. During each swing, the gastrocnemius, biceps femoris, gluteus maximus, pectoralis major, latissimus dorsi, and triceps brachii were evaluated for electromyographic (EMG) activity. EMG values were normalized to EMG measured during maximal voluntary isometric contraction. Statistical analysis revealed no significant differences in EMG activity across the three treatments. In addition, the results displayed a specific muscle recruitment order during the swing, starting with the lower body followed by the upper body muscles. This study was the first to report the recruitment order during the baseball swing. Although acute exposure to WBV did not significantly alter the muscle recruitment, these results may prove useful for practitioners looking to enhance baseball swing performance. 相似文献
