这篇论文描述了一项在全美高中生物课堂上进行的随机对照疗效研究。在这项研究中，教师们实施了数据掘金的使用，这是一种旨在将真实的研究和数据带入课堂的活动。这些材料可以嵌入到任何给定课程的现有教学模式中，从而为这些课程注入科学故事和相关数据集。我们的设计让教师将数据块整合到他们的一个班级部分中，同时以照常的方式教授第二个班级部分。尽管在两种情况下的学生在研究学期的过程中在定量推理方面都有类似的进步，但我们发现，与只使用标准教学的学生相比，使用干预教学的学生有几个关键的差异。在使用数据块的教室里，学生们花了更多的时间从事科学实践，他们构建科学解释的能力有了更大的提高。此外，使用干预活动的学生在与数据相关的任务中的自我效能感和对STEM职业的兴趣都有所增加。最后，评估了使用数据块时教师实施对学生结果的影响。
This paper describes a randomized and controlled efficacy study conducted in high school biology classrooms across the USA. In this study, teachers implemented the use of Data Nuggets, activities designed to bring real research and data into the classroom. These materials can be embedded within the existing instructional modality of any given curriculum, thus infusing these curricula with science stories and associated datasets. Our design had teachers incorporate Data Nuggets into one of their class sections, while teaching a second class section in a business-as-usual manner. Although students in both conditions improved similarly in quantitative reasoning over the course of the study semester, we saw several key differences for students taught using the intervention as compared to those taught using only standard instruction. Students in classrooms that utilized Data Nuggets spent more time engaged in the practices of science and had greater improvement in their ability to construct scientific explanations. In addition, students using the intervention activities showed increases in both their self-efficacy in data-related tasks and their interest in STEM careers. Finally, the effects of teacher implementation on student outcomes when using Data Nuggets were assessed.
