发布时间：2018-11-03 09:35
【摘要】：投影作为重要的教学辅助手段引入高校已有20多年。以往的研究更多地关注了投影对学科的适用性和对师生的影响等,缺少针对全国范围内、一线教师使用情况及偏好的调查。本研究选取全国7个片区3000多位教师进行问卷调查和访谈,发现以下主要结论:(1)目前投影在高校已成为重要教学工具,近75%的教师每周使用2-3次以上,其中甚至有20%每天都在使用;(2)投影内容方面,67.5%的高校教师选择"文字"作为投影最多的内容,并且投影内容与学科专业显著相关;(3)"线条清晰度"和"画面流畅度"分别是教师对文字和图片类内容的最看重的效果;(4)教师们普遍认为"稳定性"、"亮度"和"对比度"是投影机最重要的三大指标,但是当前对它们的满意程度却未成正比,并藉此提出一系列建议。
[Abstract]:Projection has been introduced into colleges and universities for more than 20 years as an important teaching aid. Previous studies have paid more attention to the applicability of projection to the subject and the influence of teachers and students, and lack of a nationwide survey on the use and preference of front-line teachers. In this study, more than 3000 teachers in seven regions of China were investigated and interviewed. The main conclusions are as follows: (1) projection has become an important teaching tool in colleges and universities at present, and nearly 75% of teachers use it 2-3 times a week. Even 20 per cent of them are used on a daily basis; (2) in terms of projection content, 67.5% of college teachers choose "text" as the most projective content, and the projection content is significantly related to the subject and specialty; (3) "line clarity" and "picture fluency" are the most important effects of teachers on text and picture content; (4) the teachers generally think that "stability", "brightness" and "contrast" are the three most important indexes of projector, but their satisfaction is not proportional to them at present, and a series of suggestions are put forward.
