AbstractApplications based on the current living creatures are already a lot on the internet, but there are still few who utilize the application as a source of learning. This research aims to know the response of prospective biological teachers and effectiveness of iNaturalist applications. The research method used is qualitative descriptive. The population in this study is all students in Biology education department in one of university in East Priangan, Indonesia which contracted the course of zoology vertebrates of the academic year 2018/2019 with the sampling used is the total sampling. The data used in this research form the data of exploration of students to various surrounding animals in Tasikmalaya, both animals in the wild, zoos, and pets as well as student response questionnaires. The results showed that there were 5488 observations with the most uploaded animals,Felis domestica(234 Observations). The Data shows students tend to search for animals that are only around them and students do more observations in captivity. Despite this, the application contributes well to students, because with the application students learn more about the taxonomy of vertebrate’s animals and the opportunity to know with scientists and citizen science from various fields around the world.

Abstract
In learning science, students can use the laboratory experiments and virtual laboratories (PhET) provided directly. This study aims to look at the comparison of students’ science process skills to the experimental and virtual laboratories in the aspects of formulating questions, measuring, conducting experiments, interpreting data, concluding and communicating. The instrument is in the form of an observation. The study was conducted on students who numbered two classes. In the first class, data collection was carried out using practicum methods with a total of 35 students from 40 students. While the second class collected data using a PhET simulation with a total of 36 students from 40 students. The research method used is experimental research using quantitative methods. At measuring aspect sig = 0.031, conclusion aspect sig = 0.010, and communicating aspect sig = 0.010 meaning statistically this difference is significant. Whereas in formulating the question aspect sig = 0.628, observing aspect of sig = 0.130, and collecting data aspect of sig = 0.218 means that this difference is not statistically significant.The results are the use of virtual laboratories has a better percentage value in student learning compared to the use of experimental laboratories on Archimedes Law.
