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.

“地球科学数据谜题”的开发和测试：低入门门槛的数据使用活动该奖项用于设计和测试一种面向初高中学生的数据使用活动形式，该活动对教师的入门门槛较低，对学生的洞察力与努力的比例较高。这些“数据谜题”强调通过使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分钟到一个小时内解决，利用定量推理和地球过程知识，提供从数据中出现模式、趋势或解决方案的发现时刻，并附有丰富的教学内容知识文档，供教师使用。对于那些自己很少或根本没有使用数据来回答问题或解决问题的经验的教师来说，正确构建数据谜题将成为通往数据教学力量的桥梁，如果渗透到课程中，将为那些已经习惯使用数据的教师提供频繁使用数据的机会。数据拼图的测试套件正在通过一个在职专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在科学领域代表性不足的人群。两组教师，一组具有丰富的调查和数据分析专业知识，另一组没有重要的数据工作经验，将被用来测试和审查作为该奖项一部分的六个数据谜题。
