John,
One is to be early to class and sharing a supportive word with students as they come into class. You can compliment students individually for their work, questions, contributions, etc.. This is a powerful way to motivate them. Another is to recognize their effort via a personal message on their projects or evaluations. Receiving these comments helps them to see that they are progressing in the course and are being successful.
