Improving content area reading comprehension of Spanish speaking English learners in Grades 4 and 5 using web-based text structure instruction

Reading and comprehending content area texts is important for academic and professional success as well as life skills necessary to maintain good health and quality lifestyle. Spanish speaking English language learners have shown poor performance on high-stakes assessments in reading comprehension. The number of Spanish speaking English learners (ELs) in our schools continues to increase at a fast pace, and therefore it is imperative that we address their reading comprehension needs swiftly and effectively. The text structure strategy has shown positive results on comprehension outcomes in many research studies with students at Grades 2, 4, 5, and 7. This study is the first implementation of instruction about the text structure strategy expressly designed to accommodate the linguistic and comprehension needs of Spanish speaking ELs in Grades 4 and 5. Strategy instruction on the web for English learners (SWELL) was designed to deliver instruction about the text structure strategy to Spanish speaker English learners. A randomized controlled study with pre and post-tests was conducted with 14 classrooms at fourth-grade and 17 classrooms at fifth-grade in high poverty schools where over 85% of students were Spanish speaking bilinguals or ELs. Analysis of data using multi-level models show moderate to large-effects favoring the students in the SWELL classrooms over the business as usual control classrooms on important measures such as a standardized reading comprehension test and main idea and cloze tasks. This research has practical implications for the use of web-based tools to provide high-quality and supportive instruction to improve Spanish speaking ELs reading comprehension skills.

自动语音识别技术在聋儿计算机辅助教学中的应用——聋儿言语训练软件的原型架构

自动语音识别(Automated speech Recognition)是一种将人的语音转化为文本的技术,它已被运用到了包括教育在内的众多领域,然而在聋儿言语训练领域的应用中却明显滞后。本文通过对采集到的大量聋儿言语信息进行筛选,基于对聋儿语音特点的深入研究,综合国内外先进的语音识别技术,从技术的角度,阐明了言语训练软件原型从前期准备、分析设计到最终架构完成的详细过程,并且创造性地提出了几点架构思路,尤其针对聋儿自身特点,实现了一些针对性强的功能。
