The Activity report in Administration block > Course administration sums the views of all roles in the course including the teacher role. IMHO, this is a huge problem.

I can't expect any teacher would care how many times they click on their own resources. What they really want (and expect) to see from this report is how their class of students are engaging in the course content. So, in this current state, this report is not providing any good data for the teacher role it is created for.

If teachers really want to see a report on their own activity, they can do that under My profile settings > Activity reports > Outline report.

I would request that only views by the student role is shown by default. Secondarily, there could be a pulldown menu to filter by other roles and or select view by individual participants - see https://tracker.moodle.org/browse/MDL-49229
