Implementation tips

Maintain focus on the process

Students often get distracted when they reach the data collection stage. The data becomes an end in itself. They want to record the data, record all the data and record nothing but the data. From my perspective, recording data should be the least of their concerns.

The really important piece is the process of data collection. The accuracy of the data is directly determined by the process used to collect it. The issues of random sampling and student involvement are both addressed through a discussion of the process. The process of collecting data is what the students will remember five years from now.

Try to emphasize the process with the students. Ask them to record their processes carefully. As I mention in the textbook, they shouldn’t be afraid to be tedious and dull at this point.

Subtle issues in data collection

I have emphasized integrity and accuracy in this chapter of the textbook because these issues are very subtle and often misunderstood by the students. Full understanding of these issues requires being able to see the data collection process from the perspective of writing the final conclusion. Many times the students are not able to do this so they will be looking to you to help them through these issues.

Measuring devices

The science department is usually a good resource for accurate measuring devices. Often, the students just need to ask and they can use a lab after hours or check out equipment. Naturally, the rules of the science department should be respected in all cases.

Points for the data collection

I recommend assigning 15—20% of the points to documenting the process of data collection.
