Assessment: Teacher-centered or Learner-centered?

As part of this week's readings and assignments, I completed this survey, looking at if I have a teacher-centered or learner-centered outlook on learning. Based on the survey results, I lean towards learner-centered.
I would have to agree with this result. Students are the most important part of a class. The whole point is for the students to learn, and the instructor needs to think about what will help those students learn the most. Not all students learn in the same way. Some learn from discussions and peer feedback. Others learn through hands on activities. Although it is the most common classroom format, students don't always benefit from sitting and listening to a teacher lecture. In order to be most effective, instructors need to be aware of this, and vary thier lessons to suit the needs of thier students.
Another piece of any course is assessment. The most prominent form of assessment is seen in tests and quizzes. Unfortunately, these don't give the whole picture. Some students don't do well in testing situations. I am a math teacher in a cyber school. Many of our tests are multiple choice (Not my decision, but what I work with). There have been plenty of opportunities where I see that students get a question wrong on a test because they missed one negative sign in a problem. Does this mean that they don't understand the material? Does that mean they should receive a failing grade on the test? In my mind, the answer is no. You can't just look at one piece of the puzzle. You have to look at all of the pieces to see the entire picture.
