Checking for answers, or solutions revisited

We live in a world where information and data is becoming more and more easily available. Before I had mentioned time and time again how for students we should always be checking for solutions and not answers. I think this genuinely extends to problems with cheating and academic integrity as well. It's so easy for students to take pictures of their homework and send it to friends to copy off of, look things up in the middle of the test by going to the bathroom, and so on. We live in an age where the boundary between collaboration and cheating has become very thin. In the future we will most likely find ways to easily deal with problems like these but as of right now we are at a crossroads. Do we have students completely separate themselves from the world when taking tests? That doesn't seem fair seeing as we are always trying to encourage collaboration and team work. But meanwhile, having students discuss problems and leave the potential for cheating available is also not the right way to do things. I think this is especially because our society puts emphasis on grades and not understanding. Students cheat because they don't want to fail and they don't realize that by cheating they are not understanding and by not understanding they are setting themselves up for even bigger problems down the road. I believe that in our classrooms we need to be thinking about these questions and find a balance between what constitutes cheating and what is collaboration.
