Carelessness is defined as failing to pay attention to detail or failing to perform anything well enough or appropriately. A careless error is one that you make because you are not paying close attention. For example, if you are writing a paper and leave out some important information, that would be a careless error. There are two types of careless mistakes: procedural and conceptual. With procedural mistakes, you miss steps in a procedure because you are not following it properly. For example, if you are cooking and use the wrong measuring spoons, that would be a procedural mistake. Conceptual mistakes occur when you omit things from your work entirely. For example, if you are writing a paper and forget to include a reference page, that would be a conceptual mistake. Both procedural and conceptual careless errors can cause major problems for you and your school project. If you miss important details in your paper, others might skip reading it altogether. This could hurt your grade because projects that aren't read do not get graded. If you make a conceptual error, you will need to start over from scratch. You might be able to cut some slack if you're making an honest effort but if many careless errors continue to appear in your work, you may have to submit another copy.
