Set clear learning goals at the beginning of the class and stick to them. Help your student succeed by letting him know exactly what you expect of him, from the skills he should be gaining to the pace at which he should be learning. If you expect your students to reach a typing speed of 60 words per minute by the end of the class, make sure your students are aware of that requirement as soon as possible so they can begin working up to it.
Give your students all the information they need to do well in your class. Many students in an adult computer technology class enrolled because they want to improve their computer literacy skills; many students in a required elementary computer course have never touched a computer before. Don't assume that your students already know certain things about computers, like how to change the font in word processing programs, because chances are high that at least one of your students doesn't know how to do what you're telling her to do.
Give periodic quizzes and exams to test your students' progress. These can be written group tests on concepts you've taught in class or individual hands-on exams. Giving periodic exams rather than one cumulative exam at the end of the class will help you identify students who are not making adequate progress early on.
Evaluate students according to your class standards and expectations. Being too harsh on your students is not recommended, but neither is grading too easily. Follow the rubric you set for each student. Evaluate students fairly and accurately based on their actual progress with the material.
