WACO, Texas (Nov. 10, 2016) – The School Science and Mathematics Association (SSMA) honored Erin Dixon, Ph.D., visiting lecturer in science education in the department of curriculum & instruction in Baylor’s School of Education, with a national award for her outstanding dissertation.
Dixon’s work compared two methods of science instruction: inquiry teaching and direct teaching. Dixon credits her enjoyment of teaching for setting her on the path toward an award-winning dissertation.
“Part of why I started the Ph.D. program was because I wanted to learn the best ways for teaching science,” said Dixon, who graduated in August of 2015.
The SSMA Dissertation Award recognizes exceptional doctoral degree research in the fields of science education, mathematics education or integrated science and mathematics education. While a non-member of SSMA is eligible for the award, a member must nominate them. Suzanne Nesmith, Ph.D., associate professor and associate dean for undergraduate education in Baylor’s School of Education, nominated Dixon.
Nesmith said, “I think it’s wonderful she earned this honor, because she is so deserving of it. You can see her interests and her passion in the words in the project itself and I’m so proud of her.”
Teaching was not always the direction Dixon saw her life headed. She graduated from Baylor with an undergraduate degree in nutrition and worked as a dietician for several years. However, Dixon decided the field of nutrition was not a career she wanted to continue, so she enrolled in the Baylor’s School of Education for a 14-month master’s and teacher-certification program and graduated in 2008.
While in the program, Dixon taught science classes at West High School, and she continued teaching there for five years. It was during her teaching experience at West High School that Dixon noticed a lack of engagement from students. She began to research teaching methods and learned about inquiry teaching — a science education method where teachers guide students through hands-on learning with experiments, followed by explanations of definitions and concepts. Dixon realized she was not using an inquiry method, and she wanted to learn more about teaching science by pursuing a Ph.D. from Baylor’s School of Education.
“Dixon worked as a graduate assistant for me, she taught part-time at a local high school, and she took courses,” Nesmith said. “She has always been incredibly disciplined and passionate about science education.”
Dixon learned that, while science education experts regard inquiry as the best form of teaching, teachers typically teach by a direct method —where students learn concepts from Power Points and class instruction with experiments tagged onto the end of a lesson. Dixon realized the startling academic differences between inquiry and direct teaching methods.
“Through the inquiry method, students have an opportunity to experience the science concepts first,” Dixon said. “After they’ve experienced it, through discussion, rather than lecture, the teacher can introduce those concepts and terms to the students as the students describe their experiences.”
Dixon’s passion for teaching in general evolved into a passion for specifically inquiry-based instruction. Choosing the comparison of teaching methods for her dissertation was an easy decision. As with her master’s program, Dixon taught at least part-time throughout her entire doctorate program. This allowed her to research the two teaching methods with her own ninth-grade students at Rapoport Academy High School.
Before a two-week unit about diffusion and osmosis, Dixon gave four different classes two pre-tests — one test was multiple-choice and the other was an open-ended essay question. Dixon then taught two classes through inquiry instruction and two classes through direct instruction. All four classes took the same pre-tests as post-tests after completing the unit.
Dixon said, “What I found was that both groups performed similarly on the multiple-choice test. They both showed some improvement in their understanding of the science concepts based on the multiple-choice test. But what showed the difference between the groups, was the open-ended essay response. The group I taught through direct instruction still had a lot of misconceptions and their explanations were more superficial than the group I taught through inquiry.”
Dixon’s dissertation expanded upon her research and the implications of her experiment. Following the completion of her dissertation in the summer of 2015, Dixon now advocates for inquiry teaching to be implemented more in schools. Dixon is also teaching her first full-time semester in School of Education at Baylor. She helps prepare teachers for teaching science in schools and supervises pre-service teachers. While Dixon misses teaching high school, she said higher education incorporates her passion for studying and preparing the next generation of science teachers.

Baylor University is a private Christian University and a nationally ranked research institution, characterized as having “high research activity” by the Carnegie Foundation for the Advancement of Teaching. The University provides a vibrant campus community for approximately 15,000 students by blending interdisciplinary research with an international reputation for educational excellence and a faculty commitment to teaching and scholarship. Chartered in 1845 by the Republic of Texas through the efforts of Baptist pioneers, Baylor is the oldest continually operating University in Texas. Located in Waco, Baylor welcomes students from all 50 states and more than 80 countries to study a broad range of degrees among its 11 nationally recognized academic divisions. Baylor sponsors 19 varsity athletic teams and is a founding member of the Big 12 Conference.

Founded in 1919, the Baylor School of Education is accredited by the National Council for Accreditation of Teacher Education. The School prepares leaders beginning in undergraduate programs, continuing through master’s-level work and culminating in both Ed.D. and Ph.D. programs; impacts the world as students participate in faculty-guided fieldwork, service learning and community-focused research in local and global contexts; and shapes the future by mentoring the whole person, developing an understanding of theory and practice and encouraging responsiveness to one’s calling.
