Development of Inquiry-Based Instructional Videos for Teachers in Undergraduate Geoscience Education

为了满足替代传统课堂教学策略的需要，我们准备并改进了一些材料，这些材料对如何在课堂上结合探究性学习、实践活动和以行动为导向的科学调查提供了明确的指导，特别是对地球科学的入门课程。我们已经开发并测试了一系列视频模块，这些模块说明了基于探究的教学方法的良好实践。模块主题包括引导讨论，提出问题（苏格拉底式方法），在讲师指导的演示中引导探究，以及在讲座中使用同伴学习技术。每个时长不到15分钟的模块包括：1)经验丰富的教师讨论如何鼓励和指导课堂讨论的视频片段，2)学生参与小组和同伴学习的真实课堂活动，以及3)教师和学生主导的演示。视频资源使教师能够在课堂上看到实际的例子。对两个视频模块的初步测试表明，教师们更欣赏视频的这一方面。这些模块的使用者可能是刚开始教学的人，或者是在传统课堂上更有经验的人，但他们愿意尝试新的方法。这些模块在不同类型的机构进行测试，包括两年制和四年制的学院和大学。一个顾问委员会协助编辑视频。在充分开发后，将广泛分发这些模块，并附上一份简短文件，指导如何使用这些视频。除了供个别教员使用外，这套由七个最终视频模块组成的套件还可以用于培训助教，或者它们也可以成为系内关于教学的讨论的焦点。

Geology (42) To meet the need of alternative teaching strategies to the traditional lecture, we have prepared and improved materials that provide explicit guidance on how to incorporate inquiry-based learning, hands-on activities, and action-oriented scientific investigation in the classroom, particularly for introductory classes in the Earth sciences. We have developed and tested a series of video modules that illustrate sound practices in inquiry-based instructional methodology. Module topics include leading discussions, posing questions (Socratic approach), guiding inquiry during instructor-led demonstrations, and using peer learning techniques during lecture. Each module of less than 15 minute duration includes: 1) video footage of experienced faculty discussing ways to encourage and guide discussions in the classroom, 2) real classroom activities in which students are involved in group and peer learning, and 3) both instructor- and student-led demonstrations.. The video resource enables the teacher to see actual examples in action in the classroom. Preliminary testing of two video modules demonstrates that faculty appreciate this aspect of the videos more than any other. Users of the modules may be new to teaching or more experienced in the traditional lecture yet open to trying new approaches. The modules are tested at different types of institutions, including 2-year and 4-year colleges and universities. An advisory board assists in editing of the videos. With full development the modules will be disseminated widely, along with a short document that provides guidance on how to use the videos. In addition to use by individual faculty, the suite of seven final video modules could be used in training of teaching assistants, or they could be the focus of departmental discussions on teaching.
