问题     In deference to a world enthralled by shows like "Extreme Makeover" and "Keeping Up With the Kardashians," the public school district in Washington has hired a reality television company to produce videos intended to improve the skills of its teachers. The 80 videos, 5 to 15 minutes in length, are peppered with quick jump cuts, slick screen labels and a jaunty soundtrack. In short interviews and classroom snippets, the district’s highest-performing teachers demonstrate how they teach a range of lessons, from adding decimal numbers to guiding students of differing ability levels through a close reading of the Marshall Plan.
    The videos, financed by a $900,000 grant from the Bill and Melinda Gates Foundation, were developed as a complement to Washington’ s evaluation system, known as Impact, in which teachers are judged on student test scores and classroom observations. Through these evaluations, versions of which are being put in place across the country, teachers receive feedback on the areas where they need to improve, as well as a numerical rating. But many of Washington’s teachers complained that they needed examples of the highest performing level. Because teachers spend most of their days isolated in their own classrooms, they rarely get a chance to observe their peers. The videos give them a way to peek behind the closed doors of their colleagues.
    Now, with new national curriculum standards driving teachers to modify their longstanding teaching practices, a broad range of school districts, universities, companies and nonprofits are rushing to develop online video libraries showing model teaching. A nonprofit group allied with the New York State Department of Education is developing a series of about 200 videos demonstrating lessons aligned with the Common Core standards for reading and math that 45 states and the District of Columbia have adopted. Teaching Channel, a nonprofit, has a collection of more than 500 professionally produced videos of teachers recommended by school districts and other teacher organizations. The University of Michigan is indexing about 16,000 videos of fourth- through ninth-grade English and math teachers in six urban districts. And hundreds of amateur clips have been uploaded to YouTube by individual teachers.
    Education experts warn that video needs to be part of a broader program of professional development, comparing the use of video in teaching to how it is used by athletes. In Washington, evaluators and principals will recommend specific videos to teachers. Jill Nyhus, senior director of technology for the Washington schools, said principals or instructional coaches would also convene gatherings where teachers could discuss the videos.
What is the main idea of the passage?
选项 A、The change of teachers’ evaluation system.
B、The impact of TV on classroom teaching.
C、Videos get into teachers’ daily work.
D、A new way of improving teachers’ performance.
答案D
解析 本文首先以受欢迎的电视真人秀节目引出了华盛顿校区的新举措，即与电视公司合作，拍摄优秀老师的教学视频，来帮助教师改进教学。第二段介绍了教师们对这些视频的态度，第三段列举了大量制作此类视频的机构和组织，最后一段是教育专家们对这些视频使用的一点建议以及华盛顿校区的实际使用情况。因此。全文都是在介绍这些专为提高教师教学质量而制作的视频，所以文章是介绍了一种新的改进教师工作表现的方式。D项“一种改进教师工作表现的新方式”为正确答案。A项“教师评估体系的变化”，B项“电视对教室教学的影响”，均以偏概全。C项“视频走进了教师的日常教学”，原文没有提到。
