ITR/PE: Latent Semantic Analysis: Theory and Technology

EIA-0121201 Kintsch，华特大学科罗拉多州分校ITR/PE：潜在语义分析：理论与技术本研究计划旨在激励、创造和评估一种新的学习理论和方法，其中使用计算机对写作和演讲的分析来教会学生更有效地处理和理解信息。这项工作将向教育工作者提供有关教学和评估策略的信息，以提高阅读理解能力，使其达到今天学校尚未出现的程度。该方法将教会学生更有效地阅读，并从他们所读的内容中理解和学习更多。由于该方法可以应用于任何文本，它可以被纳入阅读程序以提高阅读成绩，并被用作提高科学和数学成绩的有效工具。本工作旨在实现四个方面的理论和研究突破：(1)扩展LSA以纳入句法和语义信息；(2)通过改进其概念和数学框架来扩展LSA的权力和范围，以包括其他处理隐喻和因果推理等现象的心理过程模型；(3)将LSA扩展到处理自然连续语音的转录，使LSA能够用于教授那些写作或打字能力不足以产生语篇反应的儿童对阅读和口语文本的理解；以及(4)这些理论进步证明，这些理论进步提高了不同年级、伦理背景和不同学科的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.
