Reflection: Developing a Conceptual Understanding Freshwater Pollution Testing - Section 2: Freshwater Pollution Test


Collecting data is easy, but for many middle school students, analyzing the data is difficult. Piecing together a variety of observations, information from a professional presentation, and data from experiments is a daunting task. My students are rich with data, but poor with insight. I know that students need to be led through a data mining experience so they can start to make connections and fit the pieces together.

To start with, I ask students to determine which data to look at and which data to ignore. It's like a word problem in mathematics, not all data is quality data or needed to solve the problem. So I develop higher level questions to help guide students back to the original essential question for this problem-based learning experience, "What are the benefits of parks in a community?"
