Launch Grant: Peer Feedback in Upper School Biology Class

Upper School science teacher Amanda Borking did a launch grant this year to explore the use of peer feedback through the PowerSchool class website. Students used the wiki-pages feature of PowerSchool to post content. They uploaded work there (such as this drawing of a chemistry example) and then used discussion boards to discuss their work. They also recorded and uploaded videos to add a more personal means of communication asynchronously.


In this example, students made a cartoon strip to illustrate chemical bonding.  

A few examples of peer feedback comments posted to the discussion board:

"When looking at their fairytale I really like how they represented the loss and gain of electrons by using shoes, I thought that was a really smart way to show this action. One part that was a little unclear was which atoms were bonding was which ones, I didn't figure it out until the end when you drew the final solution/equation. So in the future I would just write which atoms each ones are just to clarify. Secondly, another way to improve your fairytale might be to use more of the scientific words we learned such as ionic bond, valance electrons, intramolecular bonds, etc to relate your fairytale more to what we have been learning in class."

"I really liked their representation of how the two Chlorine atoms get the one needed magnesium electron. I think that perhaps they could have used more vocabulary such as non-metals and metals, or ionic or other words to describe what kind of reaction is taking place. I think that they could have also added a more scientific picture of what the atoms would looks like when they had shared them. I'm  a visual learner and it would help me understand the movement of atoms a little more. However, this group did an excellent job and I truly loved what they put on their story board."
