Students working at a distance in two different ILSs share a simulation similar to the Rate of Photosynthesis Lab, but are able to control only one of two variables (lamp intensity or the season of the year). Changes made in one version of the simulation are simultaneously shown in the other version. The season of the year variable is a distractor option. It does not influence the rate of photosynthesis because the aquarium plant is indoors and its water temperature does not change.
This lab is primarily aimed at promoting collaborative problem solving skills. It is suggested that the ILS for students using the version with lamp intensity controls ask students to answer the question ‘How does the rate of photosynthesize depend on the season of the year?’ Similarly, the ILS for students using the version of the simulation with season of the year controls should ask students to answer the question 'How does the rate of photosynthesize depend on lamp intensity?' In this way both groups of students can only succeed if they synchronize their actions and collaborate to answer their respective questions. For collaboration via text-based messaging it is suggested to use the SpeakUp app in the ILSs.
Instructions for use:
1.) When you click on the "Create Space" button you will create an ILS that has two versions of the Collaborative Rate of Photosynthesis Lab in the investigation phase. The version labeled ‘Rate of Photosynthesis Lab - only light intensity control’ will allow a user to adjust only the light intensity in the simulation. The version labeled ‘Rate of Photosynthesis Lab - only season control’ allows a user to adjust only the season of the year.
2.) Because two versions of the lab are created you should delete one of them and rename your ILS appropriately (e.g., Rate of Photosynthesis Lab - Version A). Then return to the Collaborative Rate of Photosynthesis Lab page at Golabz and click again the button "Create Space". This will create a new ILS with the two versions of the simulation. Simply delete the version of the lab for which you already have an ILS of and rename the new ILS appropriately (e.g., Rate of Photosynthesis Lab - Version B).
3.) The Collaborative Rate of Photosynthesis Lab is meant to be used together with a chat tool, such as the SpeakUP app, so that students can communicate with each other. Include the SpeakUP app preferably before the lab. To use the SpeakUP app, students are required to enter a common room number or create a room and share the number of the room with the other student(s). As a teacher you can also create multiple room numbers using the SpeakUP app and assign them to students as you like. This will allow you to access their chat transcripts later to read how they communicated with each other. The Collaborative Rate of Photosynthesis Lab starts by asking users to enter a chat room number (which users of the SpeakUP already have). As long as two users enter the same room number they will then share the same simulation. Please instruct your students in the ILS that they will not see the lab without a chat room number.
