ZAPS will enhance the liveliness of your class.
No matter how large your class is, individual students can come forward and perform an experiment ZAP (e.g., the Stroop ZAP) in front of the class. The whole class can follow what the student does on the projection screen and then together discuss the results. The ZAPS data collection feature can be used to inform the discussion with results for the class as a whole.
For experience and discovery ZAPS, the teacher may take the lead, showing the ZAP to the class and asking the students to predict what will happen or to suggest the action to be taken by the teacher. This can be done in response to input either from individual students or from the class as a whole. In front of a class only the interactive part of the ZAP needs to be done with the class. The teacher can set up the introduction to the ZAP and explain the theory afterward.
In a lab situation, the complete ZAP is used. Students read the introduction and the theory themselves. With ZAPS, students can work individually; the teacher simply has to be present to answer questions. Occasionally an individual student gets data out of his or her experiment that will not match the theoretical expectations. The teacher might then explain that experiments are done with a large number of subjects and that the data presented in textbooks are based on these large samples.
ZAPS data collection is a great tool to demonstrate this. Students can work with a ZAP on their own while the data from the class or group are being collected in real time. The teacher can use this class data either on-line in the lab situation or in a lecture at some later time.
