This communication describes the second wave of improvements of the remote laboratory for secondary education iLabRS. The laboratory is intended to provide experimental activities to high school students using the University facilities. A secondary goal is to promote the interaction between both education levels. The new features include the control software which dynamically manages the LabView virtual instruments and remote panels and which assigns resources to up to 20 simultaneous users of the same experiment. Also new experiments have been added, including the measurement of light sources efficiency and spectrum, a robotic arm or the control of DC motors. An evaluation campaign has been carried out with students from 15 high schools. Also a training course, followed by 35 high school and professional training teachers has been performed.Index Terms-Remote laboratory, secondary education, outreach INTRODUCTIONAlmost al l rem ote 1 aboratories whi ch are described in the litera ture [1 -3 ] are designed to be u sed i n th e University en vironment.

Abstract-iLabRS is a remote laboratory developed in Telecom BCN, the Telecom and Electronics Engineering School of the UPC with the key participation of a Secondary Education Technology teacher. Students and teachers can access to real experiments in the electronics and physics areas using a web browser. The remote experiments have been designed to partially cover the technology curriculum in the last two high school years with a triple goal: (1) to enrich the set of laboratory experiences available in High Schools, (2) to provide a clear example of the possibilities of internet-based technologies and (3) to promote the interaction between University and Secondary Education. Currently, there are 13 different experiments available. A pilot evaluation experience was carried out, in collaboration with 7 High Schools and around 100 students participating. In the experience assessment, the students gave a mark of 3.8/5 and the teachers of 4.4/5.
