Keeping students engaged is a must. These poster’s do the job well. They are designed to teach students information quickly and are easily understandable.
They stimulate the mind and create interest where there may have been none before.
I like to alternate the posters around the office as i have multiple eye catching graphs and charts for when the student may look up from his/her work.
