The PeTeL, for Personalized Teaching and Learning, environment was developed by scientists from the Department of Science Teaching at the Weizmann Institute of Science, software developers and experienced teachers from all over Israel. The environment was designed to promote the teaching and learning of science and mathematics in high schools in Israel, while creating a personalized experience according to the knowledge of each student at any point in time.

The PeTeL environment is created in the Moodle platform, which already exists in most of the schools in Israel, including schools which use the MASHOV environment of the Ministry of Education. The PeTeL environment is accessible for free. It is aimed for high school physics, chemistry and biology teachers in Israel and provides a separate collaborative database for each one of the subjects. Each teacher's personal environment enables him / her to manage the teaching sequence for the whole class, and presents the teacher with the real time status of the students during the teaching sequence in terms of comprehension, performance and task success. Thus supporting the teacher by enabling to personalize the teaching and learning for every student in class. This approach realizes the concept that stands at the base of the PeTeL environment. That is, the teaching sequences planned by the teacher for his / her students, are based on regular feedback of the students' knowledge about the taught topic. This feedback is aimed to facilitate the interaction between the students and the teacher, which includes an analysis of the knowledge of each student in the class at different stages during the learning process, and referring them to learning materials that best suit them.

The Ministry of Education has defined the implementation of these systems as one of the biggest challenges faced by the education system in Israel. Digital content has been determined as one of the central tools to be used by teachers in the 21st century, including the development of an abundance of content and digital environments as well as the professional development of teachers. In high school, science teachers teaching at the 5-unit level towards the matriculation examinations make very little use of digital content accessible through the learning management systems and there are very few national programs operating using such platforms. The PeTeL environment, can address the challenges raised by the Ministry of Education. The teaching and learning environment was developed based on the pedagogical and technological knowledge of the Department of Science Teaching, on the collaboration of teachers from all over the country as well as on collaboration with external companies possessing unique knowledge in techno-pedagogy and user experience, and it is accessible to all of the teachers and students in Israel for free.
