5) Bust out examples of experiments--good and bad--in order to help them see their own mistakes. And then have them fix those mistakes in their lab design. I normally do this through the discussion of my daily journal questions, but I have also give students good and bad examples of lab reports and asked them to score them. I usually give the bad one first, because they will score this one pretty high....until they see the good one. Then the great discussions begin about what makes a quality lab write-up. After those discussions, students revisit their pre-lab and revise their hypotheses and procedures. Some of the best discussions I've ever seen, however, have revolved around actual pictures taken of student experiments (both good and bad). I usually take pictures of their experiments (such as the one below) and then throw those on their daily journals with some pertinent questions to what I saw going wrong or right in the lab the day before.
UI's automated telescope facility allows students to obtain and analyse their own CCD images. This document describes the equipment, laboratory curriculum, and analysis procedures. Sampled images, several examples of lab reports, and research papers written by undergraduates are available.
Examples of Biology Lab Reports - Reed College
This example of a lab report may or may not look like the one from your healthcare provider's office or clinic. Different labs report results differently, and tests such as chemistry panels may include slightly different groups of tests. However, the general concepts illustrated here should still apply. Consult your healthcare provider if you have questions about your specific lab results.
