高中语言写作有效教学课型初探

写作教学是语文教学的一块重要阵地,所以应充分落实有效教学理念．使之形成一个不断生成的有机过程．成为一块卓有成效的教育和教学阵地,从而对学生的语文学习和生命成长、个体发展都起到十分重要的作用。教师可针对“无效教学”的不同成因（如学生缺少兴趣,思想观念有偏差、知识与信息欠缺、学习习惯不好、对学习缺少信心甚至厌学等）,设计不同的写作有效教学的课型。在兴趣和动机触发、价值观引导、知识及信息供给、阅读和写作习惯、成果展示与评价、信心鼓舞等方面综合旋力．从而有效促进学生的个体发展、提高写作水平。本文重点谈～谈笔者对几种课型的初步探索。     

Bringing text display digital radio to consumers with hearing loss

Radio is migrating to digital transmission, expanding its offerings to include captioning for individuals with hearing loss. Text display radio requires a large amount of word throughput with minimal screen display area, making good user interface design crucial to its success. In two experiments, we presented hearing, hard-of-hearing, and deaf consumers with National Public Radio stories converted to text and examined their preferences for and reactions to midsized and small radio text displays. We focused on physical display attributes such as text color, font style, line length, and scrolling type as well as emergency alert messages and emergency prompts for drivers, announcer identification schemes, and synchronization of audio and text. Results suggest that midsized, Global Positioning System (GPS)-style displays were well liked, synchronization of audio and text was important to comprehension and retrieval of story details, identification of announcers was served best with a combination of name change in parenthesis and color change, and a mixture of color and flashing symbols was preferred for emergency alerting.     

Statistical learning of action: The role of conditional probability

Identification of distinct units within a continuous flow of human action is fundamental to action processing. Such segmentation may rest in part on statistical learning. In a series of four experiments, we examined what types of statistics people can use to segment a continuous stream involving many brief, goal-directed action elements. The results of Experiment 1 showed no evidence for sensitivity to conditional probability, whereas Experiment 2 displayed learning based on joint probability. In Experiment 3, we demonstrated that additional exposure to the input failed to engender sensitivity to conditional probability. However, the results of Experiment 4 showed that a subset of adults—namely, those more successful at identifying actions that had been seen more frequently than comparison sequences—were also successful at learning conditional-probability statistics. These experiments help to clarify the mechanisms subserving processing of intentional action, and they highlight important differences from, as well as similarities to, prior studies of statistical learning in other domains, including language.
