  • ATHS 621: Assistive Technology Assessment and Outcome Measures

As a graduate herself of the M.S. Assistive Technology Studies and Human Services program, Cagle has worked in the assistive technology field for more than 20 years. She has served in many roles related to AT assessment and outcome measures. Cagle has taught for the program since 2016 and brings real-world experience to the classroom. Her many responsibilities have included academic advisement for postsecondary disability services; performing AT assessments, demos and alternative text formatting; working as a special education/secondary education high school teacher; and conducting project training for a traumatic brain injury clinic’s cognitive skills project. Cagle is deeply involved in the AT world nationally and internationally, and she brings that experience to the classroom. She is an IAAP (International Association of Accessibility Professionals) Certified Professional in Accessibility Core Competencies; a job skills trainer and job placement specialist; a member of the Association for the Advancement of Assistive Technology in Europe and the International Association of Workforce Professionals; and serves on the scientific advisory committee for Vispero, an AT provider for the visually impaired. She also works with the U.S. International Council on Disabilities, which is dedicated to international disability rights, and the American Airlines Arena accessibility committee. Her array of activities and involvement give her enormous experience assessing effective AT.

Students learn how assessments grounded in standards such as the ADA (Americans with Disabilities Act) and ICF (International Classification of Functioning) greatly increase positive outcomes for AT users, their employers and communities domestically and internationally. With her intense involvement in the field, Cagle provides students with a comprehensive understanding of AT assessment and outcome measures.

  • ATHS 502: Seminar – Human Characteristics in Relation to Usability of Assistive Technologies

David’s master’s degree in human factors and applied experimental psychology directly applies to this class, which focuses on the needs and characteristics of the AT user. She has extensive experience handling accessibility issues, with more than 20 years of involvement in usability testing and user-centered design. She also has a strong background in anatomy, physiology and psychology, central topics of this class.

ATHS 502 is the first class that students take in this program. It is designed as a "leveling and re-entry" experience for students, getting them comfortable with writing and providing an introduction to human capability and AT. This understanding serves as a common knowledge core as the cohort moves forward into more specialized classes. Rather than providing students with a lot of facts to memorize or formulas to compute, David provides students with a different way of looking at the world – one in which the individual's specific needs, goals, priorities and values are vital to making decisions. The class provides many opportunities for students to share their knowledge and unique perspectives with each other, whether they are seasoned professionals or new to the AT field.

Higginbotham’ education includes a Certificate in Rehabilitation Technology and Community-based Rehabilitation, and a Bachelor of Science Sociology, giving her a strong understanding of societal and community aspects of this field.

Her experience includes serving as coordinator and chair of the Disability Support Programs and Services department at San Diego Mesa College. As a faculty member, counselor, professor and adaptive computer technology specialist, she provides assistive technology services to students and consults on web accessibility and accessible online instruction. In addition to her extensive teaching and program management experience, she served as co-chair of the Assistive Technology Special Interest Group for the California Association for Post-secondary Education for Disability (CAPED) and regional representative for the California Community Colleges Alternate Text Production Center (ATPC). She also served on the advisory board for McGraw-Hill Accessibility Higher Education. These activities provide her with strong understanding of law and policies related to AT that she shares with students.

  • ATHS 618: Research Methods and Design in Assistive Technology
  • ATHS 697: Directed Comprehensive Studies

Kalfsbeek earned her master's degree in applied sociology, with an emphasis on engaging in applied, empirical research. She served as an investigator on several grant and university funded research projects, including social aspects of health and well-being (National Institutes of Health-funded Baltimore Women's Health Study), experiences of urban homeless women, and African American Alzheimer's service use. She also oversees disabled student programs and services at Moorpark College in Southern California.

She brings both her education and understanding of the needs of disabled her ATHS classes. Kalfsbeek earned her Ph.D. in education leadership and B.A. in psychology. Her degrees gave her expertise in research and preparing comprehensive case studies. Students learn to envision original empirical research, design and implement program evaluations useful in their places of employment, and how to write a research proposal – which can assist in future grant writing. For those interested in pursuing a doctorate, Kalfsbeek prepares them for research project development and implementation for a doctoral level dissertation.
