Robert, great post and so relevant. Regardless of the subject matter students can be apprehensive at first. By taking the time to build bridges to higher levels of learning, critical thinking and creative thinking you can bring a great deal of confidence to students that initially felt they would never be able to figure things out. Everyone starts out knowing little to nothing so the path students are taking has been navigated before and with great success. The more students know you expect them to be confused and have questions the more they will feel comfortable asking questions and learning from their own mistakes. James Jackson
