Subjects Taught

Dual-credit Biology, AP Biology, Anatomy & Physiology


I have had the opportunity to study at several institutions of higher learning.  My academic credentials are:

Bachelor of Science in Biology from Boston College.

Master of Science in Molecular and Cellular Biology from the University of Texas at Dallas.

Master of Education in Educational Administration from the University of North Texas in Denton.

Doctor of Philosophy in Immunology from the University of Texas Southwestern Medical School in Dallas.

If you have any questions or concerns, please contact me at william.simmons@chisd.net.


I hold a Texas Standard Teaching Certificate in Secondary Biology and a Texas Standard Teaching Certificate as a Principal EC-12.

I have taught in the Science Department of Cedar Hill High School for the past 18 years. Prior to that, I was employed as a biotechnology researcher and did research in biology and medicine for over 25 years.

I am also an Adjunct Professor in Biology, Anatomy & Physiology and Microbiology at Tarrant County College - Trinity River Campus and an Adjunct Instructor in Biology at Dallas County Community College - Cedar Valley College.


I am married and have three children between the ages of 27 and 33 and two grandchildren in elementary school.  I have previously taught at several levels, including undergraduate and graduate university students.  This year, I teach Anatomy & Physiology, Honors Anatomy & Physiology, AP Biology and Dual-credit Biology at Cedar Hill High School (granted through Cedar Valley College). I am also an Adjunct Professor at Tarrant County College, where I teach Anatomy & Physiology, Biology for Science Majors and Microbiology to Biology, Pre-med and Nursing Students.

At the High School level, responsibility for academic success lies ultimately with the student. However, I believe strongly that student success is promoted through a strong Teacher-Student-Parent partnership. Everyone involved in this partnership has significant responsibilities and expectations of the others involved. Parent involvement can take the form of monitoring this website, and family access to the gradebook program, which is available through the district website. 

Students should understand that my intention in teaching these high school courses is to replicate the college experience from my adjunct professor role. These courses are Powerpoint-intensive although I do incorporate activities and technology. I try to teach students how to take notes for a college science class. These are not courses where the majority of classtime is spent playing games (traditional or electronic), talking to your friends during class, ignoring the teacher and listening to music, or other diversions that students sometimes prefer to classroom learning.

Here is some useful information about the courses I teach this year:

Anatomy and Physiology is an advanced elective developed in cooperation with colleges and universities for students to explore an interest in the structure and function of the human body. The course laboratory and lecture curriculum provides students with knowledge of the human body in health and disease, with emphasis on terminology, functional components of body systems, and interrelationships between body systems. In the laboratory, students will study healthy and diseased tissue microscopically and dissect preserved, non-primate mammalian organs. This course is recommended for students considering careers in many fields, such as medicine, nursing, dentistry, forensics, psychology, personal training, therapy and rehabilitation, art, athletic competition, nutrition, teaching and child development, and for military, police, paramedics, EMTs and other first-responders. Students will probably not succeed in this course unless they are unusually curious about the structure and function of the human body. This course requires some memorization and independent study.

Advanced Placement / Dual-credit Biology (BIOL 1406/1407 at Cedar Valley College): Granting this dual credit is subject to rules and deadlines established by Cedar Valley College.  I teach this class on the campus of Cedar Hill High School using the syllabus from Cedar Valley College amended to conform to AP guidelines to prepare students for the AP exam in Biology (usually the second Monday in May). For Dual-credit students, grading, attendance, dropping classes and other aspects of this course are determined by Cedar Valley College so these student questions may be referred to the college registrar rather than the high school registrar. Understand that Dual credit students may also gain college credit by making a sufficient score on the AP Biology exam.  Individual colleges and universities worldwide determine which AP exam scores are sufficient to grant credit and/or advanced standing. While public colleges and universities in Texas accept dual-credit transfer credits, private institutions and schools outside Texas may or may not accept dual credit transfer credits. Students and parents should understand that the AP exam score is generally considered a stronger credential compared to community college credits. Contact your Counselor if you have questions about credit transfer and registering for the AP exam. I strongly recommend that all Dual-credit Biology and AP Biology students purchase a consumable AP Biology review and preparation workbook and use this resource throughout the year. Experience over the past decade has shown that cramming, memorizing and studying an AP Exam preparation booklet the week before the exam has never been successful, even for the most intelligent students. Some Anatomy & Physiology students have purchased review materials but this is not required. Many of my former Anatomy & Physiology students are now practicing nurses and physicians and these students usually report that our Anatomy & Physiology course is virtually identical to the college-level course and prepared them well for success after high school.
