ITR/PE: Latent Semantic Analysis: Theory and Technology

金奇，沃尔特科罗拉多大学博尔德分校itr /PE：潜在语义分析：理论与技术这个研究项目旨在激发、创造和评估一种新的学习理论和方法，在这种理论和方法中，使用计算机分析写作和演讲来教学生更有效地处理和理解信息。这项工作将为教育工作者提供教学和评估策略方面的信息，以提高阅读理解能力，达到目前学校尚未达到的程度。这种方法将教会学生更有效地阅读，并从他们所阅读的内容中理解和学习更多。由于该方法可以适用于任何文本，因此可以将其纳入阅读计划以提高阅读成绩，并且可以作为提高科学和数学成绩的有效工具。该工作旨在在四个方面实现理论和研究上的突破：(1)扩展LSA，使其包含句法和语义信息；(2)通过推进LSA的概念和数学框架来扩展LSA的力量和范围，包括处理隐喻和因果推理等现象的其他心理过程模型；(3)将LSA扩展到处理自然连续语音的转录，使LSA能够用于教那些不能很好地书写或打字以产生文本响应的儿童理解阅读和口语文本；(4)证明这些理论进步提高了不同年级、不同种族背景和不同学科学生对言语和文本的理解。

EIA-0121201 Kintsch, WalterUniversity of Colorado BoulderITR/PE: Latent Semantic Analysis: Theory and TechnologyThis research program is designed to motivate, create and evaluate a new theory and methodology of learning, in which computer analysis of writing and speech is used to teach students to process and comprehend information more effectively. This work will inform educators on instructional and assessment strategies for improved reading comprehension to a degree not yet present in schools today. The methodology will teach students to read more effectively and to comprehend and learn more from what they read. Since the methodology can be applied to any text, it can be incorporated into reading programs to improve reading achievement, and be used as an effective tool to improve achievement in science and mathematics.The work is intended to achieve both theoretical and research breakthroughs in four areas: (1) extend LSA to incorporate syntactic as well as semantic information; (2) extend the power and scope of LSA by advancing its conceptual and mathematical framework to include other psychological process models that handle phenomena such as metaphor and causal inferences; and (3) extend LSA to process transcriptions of natural continuous speech, enabling LSA to be used to teach comprehension of both read and spoken text by children who cannot write or type well enough to produce textual responses; and (4) demonstrate that these theoretical advances improve comprehension of speech and text by students in different grades, ethic backgrounds, and in different subjects.
