Investing in Our Future: The Benefits of Effective Reading Instruction for Economically Disadvantaged Children
Denise Ross, Ph.D., BCBA-D
Chair: Department of Inclusive Ed.
Professor of Special Education
Kennesaw State University, GA


Abstract: Third-grade children from economically disadvantaged backgrounds who struggle with reading proficiency are six times more likely to drop out of high school than their proficient peers. This gap not only increases their risk of remaining economically disadvantaged into adulthood but also has broader financial and social repercussions for their families, communities, and society at large. Over several decades, the science of behavior has developed teaching methods that significantly enhance learning outcomes for school-age children. When these methods are applied to reading instruction, they can effectively meet the literacy needs of economically disadvantaged children. In this presentation, I will describe research-based teaching procedures from the science of behavior and their application to reading instruction. I will also highlight recent advancements in science-based reading interventions that are rooted in verbal behavior analysis. Finally, I will discuss the extensive benefits of investing in effective reading instruction for economically disadvantaged children and their wider communities. This presentation will conclude with strategic recommendations for behavior analysts to form partnerships with schools and community organizations, aimed at addressing the educational challenges faced by economically disadvantaged families. (1 BACB CEU)
Learning Objectives: Participants will…
  • describe the relationships between economic disadvantage and reading proficiency for third-grade children, including the implications for high school graduation rates and long-term socioeconomic status;
  • discuss specific research-based teaching procedures from the science of behavior that improve reading skills and how these methods can be applied effectively in reading instruction to meet the needs of economically disadvantaged children;
  • develop actionable strategies for behavior analysts to partner with educational institutions and community organizations, including collaborative efforts to enhance reading instruction and overall educational outcomes for economically disadvantaged children and their families.

A Behavior Analytic Approach to Teaching Written Expression
​to Students with Autism and Intellectual Disability

Robert Pennington, Ph.D., BCBA-D
William T. Bryan Endowed Chair in Special Education Technology
University of Kentucky

Abstract: The development of written expression skills is essential to success in a range of critical life domains including academic performance, employment, and social interaction. Despite its importance, there has been little guidance from the research literature on strategies to teach students with complex support needs to write. In this exciting workshop, Dr. Pennington will describe a behavioral approach to teaching written expression to students with autism and intellectual disability. Further, he will distill findings from a decade of research investigations into practical teaching strategies for educators to implement quickly in their classrooms. Dr. Pennington will draw on decades of experience in classroom settings to engage participants as they work through activities and learn powerful new concepts. (1 BACB CEU)
Learning Objectives: Participants will…
  • provide a rationale for teaching written expression to students with autism and intellectual disability;
  • describe behavior analytic principles that have been applied to teach written expression to students with autism and intellectual disability;
  • describe strategies for teaching sentence construction to students with autism and intellectual disability; and describe strategies for teaching narrative construction to students with autism and intellectual disability.​

​A System of Instruction in a South African Township School

Kelsia King, M.S., BCBA
Director of Academics, Prospect Academy
​
Arvada, CO
​

Abstract: In collaboration with the leadership of Charles Duna Primary School and members of the New Brighton Professional Learning Community (PLC) in Gqeberha, South Africa, Partnerships for Educational Excellence and Research (PEER) International designed a flexible implementation of methods and curricula to build learner numeracy repertoires. This presentation will describe the process by which PEER team members, guided by Markle and Tiemann's System of Instruction (1967) and the Morningside Model of Generative Instruction (2020), designed assessment, facilitated teacher analysis of learner performance data, and guided teacher instructional decisions to improve learner educational outcomes in a post-apartheid elementary and middle school setting. Sensitivity to the context and contingencies in which we work in order to accomplish our mutual goals is essential. Thus, we will also discuss the social significance of effective dissemination of Instructional Design and Precision Teaching to environments in the United States and beyond. 
​
(1 BACB CEU)
Learning Objectives: Participants will be able to…
  • name at least 3 effects of the contingencies of apartheid on black South Africans' everyday life;
  • identify how gridding test results by objectives (Diagnostic and Prescriptive style) influences instructional decision making;
  • see a performance and identify the learning channel being used.

Using Instructional Design to Teach
​Autistic Children Emotion Recognition

Anna M. Linnehan, Ph.D., BCBA-D, LABA
Assistant Professor
Endicott College

 
Abstract: Many common theories describe emotions as an internally mediating process. Additionally, many scientific studies as well as teaching procedures for children rely on facial expression as the primary indications of emotions. However, these misconceptions have been recently updated or refuted by neuroscience. Additionally, while facial expression is part of the context of a description of emotions, facial expressions are not good indicators of specific emotions. The purpose of this presentation is to provide a parsimonious behavior analytic account of emotions as described by Skinner and updated by the Goldiamond-Layng theory, which states that emotions are not internal states but rather descriptions of changes in contingencies, or contingency descriptors. Emotion words are therefore treated as concepts (or abstract tacts). This presentation will discuss instructional design procedures, including content analysis, concept analysis and developmental testing to teach the recognition of the emotion-words, “fear” and “anger,” and the corresponding contingency effect (description of the consequence). Next steps in teaching, applying principles and strategies (Tiemann & Markle, 1991) will also be discussed. (1 BACB CEU)
Learning Objectives: Participants will be able to… 
  • describe why facial expressions alone are insufficient for emotion recognition;
  • distinguish between emotions and emotional behavior; and
  • identify contingencies associated with the emotion words “fear” and “anger” and explain how they can be applied in instructional settings. ​
Bio: Anna M. Linnehan is an Assistant Professor of Behavioral Science at the Institute for Applied Behavior Analysis and a faculty member at Endicott College. She holds both her master’s and doctoral degrees in Applied Behavior Analysis from Endicott College in Beverly, MA. Dr. Linnehan began her career as a professional chemist before transitioning to behavioral science, driven by her passion for using scientific principles to improve lives. Her research integrates the Goldiamond-Layng Theory, a behavioral contingency analytic approach to emotions, with instructional design to teach emotional concepts and help individuals identify and problem-solve their own emotional behavior. Her TEDx talk, "Why Reassurance Doesn’t Always Make Us Feel Better," highlights this work. In addition to her research, Dr. Linnehan is dedicated to the dissemination of nonlinear contingency analysis and assent-based procedures, applying Israel Goldiamond’s constructional approach to behavior. She also explores signal detection theory to analyze decision-making processes and behavior. Dr. Linnehan recently co-authored the book Decisions and Judgments in Ambiguous Situations: A Conceptual Introduction to Signal Detection Theory with Dr. T. V. Joe Layng. She also served as an editor and contributing author for Perspectives on Neurodiversity and Belonging: Reflections for Behavior Analysts. Her contributions extend to peer-reviewed journals, where she has served on multiple editorial boards, and she is an Advisor for the Cambridge Center for Behavioral Studies. As an educator, Dr. Linnehan enjoys teaching behavioral science at the undergraduate, master’s, and doctoral levels, inspiring the next generation of behavior analysts.

A Treatise on the Conditionability of Plants
Brendan Boehr, M.S., BCBA
Behaviour Scientist and Community Educator
St.Amant, Winnipeg, Manitoba, Canada

Abstract: Can the basic behavioural conditioning procedures that we know and love be applied to the behaviour of plants? Operant and respondent conditioning procedures are undeniably effective across the animal kingdom, including with individual cells and even bacteria and protozoa; and yet, neither in our textbooks nor our journals will you find an answer to this question. In fact, it seems our science has not even asked this question yet. But Brendan Boehr thinks the answer is (PROBABLY) YES! and in this presentation he is going to show you why. This is a treatise on the conditionability of plant behaviour; but it is more than that. It is a garden fertilized with interdisciplinary science, sprouting ambition, hoary indolence, and homemade operant rhizotrons that consistently yield more problems than solutions. So get out your gardening gloves and put on your thinking cap: these seeds aren’t going to water themselves. (1 BACB CEU)
Learning Objectives: Participants will …
  • list several reasons why the root apical meristem is a good candidate for behavioural conditioning;
  • describe equipment that could hypothetically be used to apply behavioural conditioning procedures to the roots of plants; and
  • ​describe plant behaviour using terminology commonly used by behaviour analysts to characterize animal behaviour.​
​Bio: Brendan Boehr hails from the bleak northern countryside of rural Manitoba, Canada. He likes his climate like he likes his data: cold, uncompromising, and breathtaking. His dual M.S. from the Florida Institute of Technology is put to good use delivering colorful workshops which are attended by thousands of families, clinicians, and professionals every year; and he is the creator of the 11-part Fulfilling Potential Workshop Series, which is hosted by St.Amant in Winnipeg and offered to all, free of charge. Brendan has practiced applied behaviour analysis in Canada and the USA as a behaviour analyst, university instructor, independent contractor, and consultant. He is drawn to theoretical, unconventional, and novel applications of behavior science; but you're more likely to find him writing amateur rap songs, paddling his canoe, and staring very, very closely at plants.

The Animals are Waiting: A “Freeing Up the Operant”
​Approach to Environmental Enrichment at Zoos

Rick Hester
Curator of Behavioral Husbandry
Cheyenne Mountain Zoo and Behavior Works

Abstract: Discrete trial training (DTT) is an essential strategy for teaching animals to be active partners in their medical and husbandry care. This approach has resulted in extraordinary welfare benefits and is now the standard of care in modern zoos. However, DTT is restricted by the trainers’ decisions. Trainers provide the cue, they set the behavioral criterion, they deliver the reinforcers, and they control the number of repetitions per session. Additionally, DTT occupies a relatively small portion of any zoo animal’s day. When training is the high point of their day, animals often do little more than wait for the next session to begin. After a training session has ended, animals are typically turned-out into less controlled habitats where trainers have prearranged so-called enrichment opportunities (devices and other conditions) intended to induce active animals who behave similarly to their wild counterparts. However, the goals of environmental enrichment, as suggested by Markowitz (1982), have never been realized. Recently, at Cheyenne Mountain Zoo, we have taken a free operant approach to environmental enrichment. With this approach, trainers engineer environments so that animals are free to make any possible operant response and to vary those responses as described by Lindsley (1996), such as the freedom to form and to speed responses. Two important dimensions have emerged when selecting and creating enrichment opportunities, i.e., time to satiation and time to depletion. Both strategies together, that is, 1) borrowing animals for discrete training sessions to meet our medical and husbandry goals, and 2) returning them to environments that free up their operant behavior, can greatly improve the welfare of animals in human care. 
​
(1 BACB CEU)
Learning Objectives: Participants will understand the…
  • role of discrete trial training in zoos;
  • goals of environmental enrichment.
  • free-operant principles outlined by Ogden Lindsley (1996) and their application with animals in human care.​
Bio: Rick Hester is the Curator of Behavioral Husbandry for the Cheyenne Mountain Zoo in Colorado. He oversees all the zoo’s behavior programming.

Systems Change and Science Education Interventionist
Director, Prostate Cancer Genomics Training Program at Johns Hopkins University
Office of Science and Technology Policy
Executive Office of the President | The White House 2025


​Abstract: In a time of widespread misinformation, politicized science, and urgent educational reform, Applied Behavior Analysis (ABA) stands at a crossroads. This talk explores the critical role of science in shaping behavior, informing education, and guiding the future of ABA. Drawing from the intersections of behavior science, learning theory, and public understanding, we will examine how ABA can remain grounded in its scientific foundations while adapting to the evolving demands of real-world practice. Through the lens of contemporary issues, ranging from science denial and social media misinformation to classroom interventions and policy debates, this session addresses three central questions: (1) What does the science of behavior demand from practitioners today? (2) How can ABA better inform and transform educational settings? and (3) What responsibilities do behavior analysts have in correcting misinformation and promoting scientific literacy? By bridging the gap between the lab, the classroom, and the public square, this talk makes the case that staying rooted in science isn’t just an academic exercise, it’s a mission-critical imperative for the field’s integrity, relevance, future impact and is best practice for the many students that depend on it.
Learning Objectives: 
By the end of this presentation, participants will be able to...
  • Describe the current expectations and ethical responsibilities of behavior analysts as informed by the evolving science of behavior;
  • identify strategies for applying ABA principles to improve and transform educational systems and classroom practices; and
  • explain the role of behavior analysts in addressing misinformation and promoting scientific literacy within their professional and public communities.​

Learning by Doing:
Transforming Workforce Training with Immersive Technology

Ellie Kazemi, Ph.D., BCBA-D 
CEO of Transform VXR
​Professor, CalState Northridge


Abstract: An immersive learning environment is an interactive space—physical or virtual—designed to recreate realistic scenarios or teach specific skills and techniques, including role-playing, simulations, and virtual learning platforms. Although approaches like Behavioral Skills Training (BST) are highly effective, they often lack scalability and personalization, especially when training in-person and with large groups. With advancements in cutting-edge technologies, such as artificial intelligence, immersive, experiential, and hands-on practice has become more accessible and scalable. However, the success of these experiences depends on the intentional application of instructional design principles and the science of behavior. Without proper design, guidance, and feedback, even well-intended immersive experiences, that look and feel “real”, can fall short or become ineffective. Immersive experiences within safe, scalable digital environments offer a transformative opportunity to close gaps in workforce training by fostering competence, confidence, and engagement. In this presentation we will explore how thoughtfully designed immersive learning, aligned with real-world performance outcomes, can reduce risks, improve employee confidence, and prepare professionals to thrive in evolving work environments. (.5 BACB CEU; .5 Ethics)
Learning Objectives: Participants will be able to…
  • identify the defining features of immersive learning environments, including simulations, role-playing, and conversational AI;
  • describe how to enhance learning outcomes for immersive experiences by integrating science of behavior; and
  • explain how immersive experiences can enhance teaching and learning.
Bio: Dr. Ellie Kazemi is a leading expert in workforce training, immersive learning, and outcome-driven strategies. As Director of AI and VXR Initiatives at California State University, Northridge, and CEO of Transform VXR, she pioneers AI-powered, immersive training solutions that enhance competency and performance. She has collaborated with NASA, FEMA, and the National Autism Data Registry to develop scalable, technology-enhanced training with measurable impact. Ellie founded a self-supported graduate program in behavior analysis at CSUN and authored Fieldwork and Supervision for Behavior Analysts, a widely used resource in ABA supervision training. She has also contributed to standard development, evaluation methodology, and measurement science in accreditation settings. As a principal investigator on national research grants, she has led efforts to advance simulation-based learning, AI, and workforce development. A sought-after speaker, Ellie has worked internationally and received multiple awards, including the ABAI Best Mentor Award and the Outstanding Service to the Community Award. ​

Concluding Remarks
Applied Behavior Analysis: Hard on the Problems, Easy on the Person 

Pat Friman, Ph.D., ABBP​ 
Vice President of Boys Town Center for Behavioral Health
Boys Town, Nebraska


Abstract: The underlying assumption of applied behavior analysis is a revolutionary perspective on problematic human behavior. It attributes the cause of the problems not to the misbehaving person him or herself, but to what has happened to the person over the course of their life prior to the exhibition of the problems. Thus it seeks not to fix the blame but rather to fix the problems instead. Actions stemming from this perspective are thus very easy on the person and very hard on the problems. Unfortunately only a tiny minority of the human species hold this view—they are known as behavior analysts. Their view is in direct opposition to the traditional and universal perspective on problem behavior, the most apt description of which is blame and punish. This view is hard on the person and often just makes the problem worse. In fact it is responsible for almost all of the horrible things humans have done to humans throughout history including wars, programs, genocides, martyrdoms, crucifixions, divorces, abuses, and rancorous exchanges between family members, friends, and colleagues. This talk will discuss the behavior analytic perspective and assert that each and every member of our field is an apostle for its dissemination. This is no trivial matter. Widespread adoption of the behavior analytic view could transform the quality of life on this planet. (.5 BACB CEU)
Learning Objectives: Attendees will be able to describe…
  • the circumstances view of behavior; and 
  • at least two of its many virtues.
