Purpose

Digital video is regularly used to supplement instruction in K-12 education. However, more research is needed on how teachers interactively search for video to support their instructional tasks and activities. The purpose of the study is to better understand teachers’ perceptions of their video searches which can help facilitate video needs and interactions with digital tools.

Design/methodology/approach

Based on an existing image search model, variables were constructed and adapted to reflect the experiences of an interactive video search in an educational context or setting. A survey was then implemented and presented to K-12 teachers to gather perceptions about video searches. Statistical tests were used to examine certain variables that were categorized according to video needs, search tools and video surrogates or representations. The tests included descriptive tests and mean comparisons of variables within the categories to better understand priority among the criteria of teachers when interactively searching for video.

Findings

Results produced various statistical differences between variables within each of the categories of video needs, search tools and video surrogates or representations; as a result, certain priorities among the criteria of a video search emerged.

Originality/value

Online resources, particularly digital video, are likely to keep growing in importance for instruction and learning in K-12 settings. This study provides an important step to understanding different aspects of teachers’ criteria and perspectives of the video search process which will help better facilitate fulfillment of information needs.

内容、工具和代理：评估 K-12 教师交互式搜索数字视频的标准

目的

数字视频通常用于补充 K-12 教育中的教学。然而，需要更多的研究来研究教师如何交互式地搜索视频来支持他们的教学任务和活动。该研究的目的是更好地了解教师对其视频搜索的看法，这有助于促进视频需求和与数字工具的互动。

设计/方法/途径

基于现有的图像搜索模型，构建并调整变量以反映教育环境或环境中交互式视频搜索的体验。然后实施了一项调查并提交给 K-12 教师，以收集对视频搜索的看法。统计测试用于检查根据视频需求、搜索工具和视频代理或表示进行分类的某些变量。测试包括描述性测试和类别内变量的均值比较，以便在交互式搜索视频时更好地了解教师标准的优先级。

发现

结果在视频需求、搜索工具和视频代理或表示的每个类别中的变量之间产生了各种统计差异；结果，出现了视频搜索标准中的某些优先级。

原创性/价值

在线资源，尤其是数字视频，对于 K-12 环境中的教学和学习可能会变得越来越重要。这项研究为理解教师标准的不同方面和视频搜索过程的观点提供了重要的一步，这将有助于更好地促进信息需求的满足。
