The study also pointed out guidelines to support a customized and more effective approach of the PI to the Computer Science environment, defined as CSPI (Computer Science Peer Instruction). In this work we present data related to a first CSPI use in some classes of a CS1 course taught in Python language (MC102). Specifically, this study presents the usability and reliability data relative to the use of clickers (student response systems) to support the CSPI approach. As the research is still on development, we plan to discuss the CSPI approach, its educational impact and assessment in future works. } }
