学龄儿童定期使用在线搜索工具进行信息发现任务。然而,这些工具并不一定是为了方便这些年轻用户检索可以理解的资源,并帮助低识字率的搜索者。这对教育环境尤其令人关切,因为人们固有地期望这些工具能促进有效的学习。在这篇手稿中,我们提出了一个初步的评估进行了(1)面向儿童的搜索工具的基础上产生的K-9学生的查询,分析功能,如可读性和检索结果的充分性,和(2)教师在课堂上使用的工具,分析其主要目的和目标受众的年龄范围。在所审查的工具中,我们包括YouUnderstanded.Me,这是一个增强的搜索环境,这是我们不断努力开发一个适合5-15岁儿童的搜索环境的结果,这种搜索环境可以通过检索不仅满足这些用户的信息需求而且符合他们阅读能力的材料来促进学习。这些研究的结果突出了这样一个事实,即呈现给儿童的搜索结果具有与目标受众不匹配的平均阅读水平。此外,面向教师的工具并没有超越显示他们的学生的进步,很少提供一个简单的方法来检索课堂内容,适合当前学生的需要。这些事实进一步表明,需要建立一个面向教师和学生的双重环境。
Information discovery tasks using online search tools are performed on a regular basis by school-age children. However, these tools are not necessarily designed to both explicitly facilitate the retrieval of resources these young users can comprehend and aid low-literacy searchers. This is of particular concern for educational environments, as there is an inherent expectation that these tools facilitate effective learning. In this manuscript we present an initial assessment conducted over (1) children-oriented search tools based on queries generated by K-9 students, analyzing features such as readability and adequacy of retrieved results, and (2) tools used by teachers in their classrooms, analyzing their main purpose and target audience’s age range. Among the examined tools, we include YouUnderstood.Me, an enhanced search environment, which is the result of our ongoing efforts on the development of a search environment tailored to 5-15 year-olds that can foster learning through the retrieval of materials that not only satisfy the information needs of these users but also match their reading abilities. The results of these studies highlight the fact that search results presented to children have average reading levels that do not match the target audience. In addition, tools oriented to teachers do not go beyond showing the progress of their students, and seldomly provide a simple way of retrieving class contents that fit current needs of students. These facts further showcase the need for developing a dual environment oriented to both teachers and students.
