Philosophy Statement
Many years of teaching have shown me that anyone can learn if they are actively involved in evaluating and
processing new information that they feel is relevant to their life goals. Since each student is an individual with
unique strengths, weaknesses, interests, aptitudes, and capabilities, it is up to me to develop an understanding
of the students’ prior experience and expectations “up front”. With that knowledge and the understanding of
each student’s “situation” that develops throughout the course, I design lesson plans that attempt to pique the
students’ interest and use their aptitudes and capabilities to make the classwork engaging. In each class session,
I strive to provide clear objectives and stimulating exercises focused on the learning objectives that capture the
students’ interest the minute they walk in the door, promote teamwork, cooperation and where appropriate
competition with little down time. My lecture style leans heavily on the Socratic Method and quickly follows
each topic with a list of questions to assess the students’ understanding of what I just said. I tend to lean heavily
on practical applications and comparable processes the students are familiar with because I feel it is just as
important to discover why something works the way it does as to determine how it does what it does. My long
range goal is always to increase my students’ appreciation of their mutual, vested interest in life-long learning by
involving real-world experience to develop their knowledge and perspectives.
I believe that an effective teacher is someone that is disciplined yet flexible, easy to talk to, and comfortable
with a variety of teaching techniques designed to meet the different learning style of each student. I know that

5. 5
different students learn at different rates, so I often revisit topics when the students seem to have missed a key
point. I expect excellence and am unwilling to accept mediocre work, so I encourage my students to resubmit
their work whenever possible to try to improve their grades. I try to give my students options in working
classroom assignments because that helps them to feel more comfortable and “in control” of their education. I
take care to structure the learning experience so that they feel safe and respected; get constructive,
encouraging feedback; and receive clear guidance on how to achieve the learning objectives. I create
opportunities for students to work collaboratively with people of different backgrounds and perspectives to
solve problems, perform meaningful tasks, share knowledge and responsibility, and arrive at a shared
understanding of the truth. I guide students toward the personal responsibility, decision making, and lifetime
learning skills they will need to function in the real world.
But why take my word for these attributes making me an outstanding teacher and help me address the wide
range of skills and abilities in my classroom? Why not look at how the students I have taught over the past five
years evaluate my skills. Here are my (anonymous survey) NPS scores:

Hi, Professor how are you doing? How have you been? DeVry needs you there full time! Tried all week to get help
on ECET-350 online and seems no one knows this subject except you and Professor Utukuri.
Professor Ambuehl is an awesome instructor that was not only hands-on, but communicated with his students
and helped in any way possible. I would definitely recommend him to any other students that wanted to take his
math class.
Ralph was very helpful with this class and was always available to answer my questions and assist when needed.
profesoor was very knowledgable with the information
Two great instructors that cared! I appreciate instructors that really care! Students are able to tell the
difference.
I learned a lot in this course and the professor was dedicated to making sure that we covered and understood all
the material. He really did a wonderful job.
the class was good the professor makes it really easy for us to understand the lecture
The course is great and will be very useful in my development in this field.
