TORONTO - A survey of Ontario high school students shows the majority think sex-ed classes should include all sexualities, but cellphones have no place in the classroom.

More than 2,600 students from 69 of the province's 72 school boards took part in the survey organized by the Ontario Student Trustees' Association.

Zane Schwartz, the student trustee who led the project, says students are the best measure of how education policies play out in the classroom.

Most students in both public and Catholic school boards -- 82 per cent overall -- said they believe all sexual orientations should be discussed in sexual education classes.

Nearly three-quarters were opposed to using cellphones as an educational tool, with some warning that the devices can be distracting.

Students were more divided on questions about expanding mandatory physical education to all high school grades or starting the school day later.

The survey ran from November to January and was performed mostly on Facebook.
