Counselling for Educational Problems of School Children with a Sensory Disability

This is a study of deaf children in Bhimavaram, West Godavari district Andhra pradesh. Physical disability hampers personality development of the child, because of the social stigma that such disability conditions carry. Children with hearing disability cannot speak also as they are deprived of learning and imitating sounds in the environment. Because of the disability of hearing and speaking they are segregated from the rest of world due to the lack of communication. Due to its invisible nature, the disability does not evoke the necessary response from the public. Compared to other human positions, hearing is next to mind itself, mans most important assistant for an integrated and satisfying social existence. It can isolate a person from his/her family, peers and community. Those who do not understand this disability may subject the victim to extremely negative attitudes.     

Prosody in the reading of children with specific language impairment / La prosodia en la lectura de niños con trastorno específico del lenguaje

Expressive reading is considered one of the subprocesses involved in reading fluency, and good readers show greater changes in tone and fewer unnecessary pauses than bad ones. Given the high frequency of reading difficulties in specific language impairment (SLI), there may be certain differences in the use of prosody among children with SLI. The purpose of this study was to research whether prosody in the reading of children with Spanish SLI differs from that in the reading of typical readers. To do so, 44 children (SLI and control) read aloud a text which contained declarative, interrogative and exclamatory sentences. Different prosodic parameters referring to length, tone and intensity were measured. The results showed that the children with SLI read slower, commit more errors and make more inappropriate pauses. Furthermore, fewer pitch variations were found in the interrogative sentence and in the final features of the sentence. These results confirm the relationship between decoding and prosody; therefore, interventions with these children should bear in mind the practice of expressive reading while learning reading fluency.     

视觉障碍者的跨通道重组研究综述

本文综述了近年来视觉障碍人群跨通道重组的相关研究。主要从三个方面进行了探讨视觉障碍者跨通道重组的神经基础;不同时间阶段的视觉缺失对脑内跨通道重组形成的影响;任务需求的复杂性与视觉障碍者的跨通道重组关系。这些研究成果对于促进神经康复医学的发展和重组大脑皮层某些丧失的功能提供了有价值的参考。     

用Visual Basic 6.0实现平面齿轮系传动比的计算

对于任一含有m对啮合齿轮的平面齿轮系，都可列出m个表示构件间转速关系的形式相同的线性方程式。由于这些线性方程式的形式相同，所以可通过Visual Basic6．0编程很容易地列出这些线性方程式并求解之，从而获取平面齿轮系的传动比。     

动态链接库与VB多媒体程序设计

Visual Basic(VB)以其强大的图形界面功能、可视化编程及方便的代码维护赢得了许多程序员的青睐，但在使用VB开发多媒体应用程序时，如何合理地存放大量的多媒体资源，是一件十分辣手的事。本文详细论述了一种运用动态链接库DLL对VB的多媒体功能进行扩展，实现声音播放的办法，并给出了具体实例。     

基于Visual Basic的多媒体课件设计

本文以Visual Basic6．0为开发平台探讨了使用控件快捷地制作图文并茂的多媒体课件的设计方法，并给出了一个设计实例。     

数字化学习资源画面色彩表征影响学习注意的研究

在学习过程中,学习注意是保证学习者对知识信息进一步记忆与深入思考、学习真正发生的重要前提。当前的研究仍有在数字化学习资源画面设计中,对学习注意这一重要影响因素重视不足的问题。数字化学习资源画面色彩表征影响学习注意的“关系模型”,以及促进有效学习注意形成的色彩表征设计的“操作模型”,就是针对这一问题而提出的。“关系模型”提出了数字化学习资源画面色彩表征知识内容形态影响选择性学习注意,色彩表征知识关系形态影响持续性学习注意,色彩表征知识目标形态影响分配性学习注意等观点,并从中推衍出学习注意的“自动加工→序列加工→精细加工”的过程。“操作模型”从促进有效学习注意形成、优化数字化学习资源画面设计的研究视角,提出了“色彩编码设计形式”“色彩线索设计形式”和“色彩信号设计形式”等三种色彩表征设计形式,并通过对色彩表征设计流程的系统梳理,推导出“学习注意类型分析、色彩表征设计形式分析、色彩表征语义设计、色彩表征语用设计、色彩表征语构设计”的设计流程。对数字化学习资源画面的色彩表征设计,影响着学习注意的定位策略、匹配策略和管控策略,这为提升数字化学习效果提供了新思路。
