" The effect of using the Quick Response code (QR Code) of the virtual labs on the skills of performing laboratory experiments and the time of their implementation in a sample of of Qassim college students

The purpose of the current study was to identify the effect of using the Quick Response code (QR Code) compared to the traditional response code for virtual laboratories on the skills of performing laboratory experiments and the time of their implementation among a sample of students from the College of Engineering in Unaizah, Saudi Arabia.   
The study included two experimental groups, the first uses the      default QR code-based labs, while the second experimental group used the same default labs based on the usual visual response (often animated visual forms that give a temporal indication of the content downloading), and the experiment was applied to A sample of (50) students was divided equally into the two groups, each of which consisted of (25) students. The appropriate tools were designed and prepared to address the study variables; They are: a questionnaire to define the criteria for designing a rapid response code, a note card for the skills of implementing the laboratory experiment in physics, and the content included four hypothetical experiments in the field of electric forces, carried out by the individuals of both groups separately, and the application lasted three weeks by fifteen sessions, organized Through a schedule prepared for that, and the Virtual Lab Specialist (a technically qualified person responsible for training students within the lab) was trained to observe the students during the implementation of the laboratory experiment and to register The scores of the observation card, and the time of implementation of the experiment for each student, according to the tables and records given to him And the final results of the post-application concluded that there were no statistically significant differences between the mean scores of the two groups in the skills of performing laboratory experiments. While the results confirmed the presence of statistically significant differences between the mean scores of the two groups at the time of implementing the laboratory experiment for the benefit of the members of the first experimental group who used the default lab based on the QR code and performed the same experiments in a less time. This confirms that the QR code has to do with the speed of learning, as it reduces the time required to learn The study recommended the importance of using the QR code when processing courses and training programs with simulation system, as well as expanding the experience of this system to respond to the efficiency and speed of administrative processes, in addition to conducting studies that address the impact of this variable on the learning of students of special groups, and the extent of its impact on the operations of Remember, recognize and learn .
