Positive:
+ There were some real student success stories that would not have happened in the usual laboratory sequence. I felt like all of the student groups really made and effort to put together a quality lab.
+ Whether or not students completely understood the experiments they were developing, they did have an opportunity to think of laboratory from the perspective of the “creator” and/or “producer” as well as “consumer.”
+ I think that this was a meaningful group project. I think that, as a group, students were able to accomplish things that they would not have been able to do individually.
Neutral Commentary:
±Analysis of products tended to extend the time required to complete the lab reports because it took time to collect and distribute all of the data.
±Lab development is rather time consuming to do it right. Mistakes were made because not everything was thoroughly checked through before the lab handout went into press.
±There was still a pretty big element of instructor control. I wanted to be sure that the labs were comparable to each other and comparable to labs they would normally be doing.
Negative:
- I was surprised that there was not more “ownership” of the experiment by the group who was producing the lab the day that it was being performed by their peers. I will try to increase the involvement of the group who developed the lab next time.
- There was a little more difficultly in synching labs with course content.
- I need more skill if I am going to follow the “draft” method of evaluating student work. Students tend to view resubmitting drafts as simply correcting the specific errors that the instructor pointed out. I need to write a more detailed rubric for both the lab handouts and webpages. Maybe a better way to gauge participation of each member of the group too.

Perhaps for students to take more “ownership” of their work, they could give a five to ten minute lecture during lab period on the theory behind the reactions.
Also, maybe set aside part of the Friday class period to a reflection on what happened in lab that week. Ask students to explain why the experiment is relevant to the course material. Self-explanation can be a powerful method of learning.
