Development and Testing of "Geoscience Data Puzzles": Low-Barrier-to-Entry Data-Using Activities

开发和测试“地球科学数据谜题”：低门槛数据使用活动该奖项用于设计和测试一种面向初中生和高中生的数据使用活动形式，它为教师提供了低门槛，为学生提供了高洞察力与努力的比率。这些“数据谜题”强调了用数据回答问题和解决问题的挑战和回报。数据谜题使用精心挑选的真实地球科学数据片段，可以在15分钟至一小时内解决，利用定量推理和地球过程知识，在数据中出现模式或趋势或解决方案时提供发现时刻，并为教师提供丰富的教学内容知识文档。构建得当的数据谜题将成为一座桥梁，为本身几乎没有使用数据回答问题或解决问题的教师提供数据教学的力量，如果渗透到课程中，将为已经习惯使用数据的教师提供频繁的数据使用机会。一套数据谜题测试正在通过一项在职职业发展计划进行调查，该计划包括很大一部分服务不足的社区和人口，这些社区和人口在科学领域的代表性不足。两组教师，一组具有丰富的查询和数据分析专业知识，另一组没有处理数据的重要经验，将被用于测试和审查作为该奖项的一部分而创建的六个数据谜题。

Development and Testing of "Geoscience Data Puzzles": Low-Barrier-to-Entry Data-Using ActivitiesThis award is being used to design and test a form of data-using activity for middle- and high school students that presents a low barrier-to-entry for teachers and a high ratio of insight-to-effort for students. These "Data Puzzles" stress the challenge and reward of answering questions and solving problems through using data. Data Puzzles use carefully-selected snippets of authentic geoscience data, can be solved in 15 minutes to an hour, draw on quantitative reasoning and knowledge of Earth processes, offer discovery moments when a pattern or trend or solution emerges from the data, and are accompanied by a rich pedagogical content knowledge document for teachers. Properly constructed Data Puzzles will serve as a bridge into the power of teaching with data for teachers who themselves have little or no experience in using data to answer questions or solve problems and, if permeated through the curriculum, offer frequent data-using opportunities for teachers who are already comfortable using data. A test suite of Data Puzzles is being investigated through an in-service professional development program that includes a large proportion of underserved communities and populations that are underrepresented in science. Two cohorts of teachers, one with substantial inquiry and data analysis expertise and the other with no significant experiences working with data, will be used to test and review the six Data Puzzles being created as part of this award.
